The software system of the electronic device 100 may employ a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present invention uses an Android system with a layered architecture as an example to exemplarily illustrate a software structure of the electronic device 100.

Fig. 3 is a block diagram of the software configuration of the electronic apparatus 100 according to the embodiment of the present invention.

The layered architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, an application layer, an application framework layer, an Android runtime (Android runtime) and system library, and a kernel layer from top to bottom.

The application layer may include a series of application packages.

As shown in fig. 3, the application package may include applications such as camera, gallery, calendar, phone call, map, navigation, WLAN, bluetooth, music, video, short message, etc.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 3, the application framework layers may include a window manager, content provider, view system, phone manager, resource manager, notification manager, and the like.

The window manager is used for managing window programs. The window manager can obtain the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make it accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

The view system includes visual controls such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, the display interface including the short message notification icon may include a view for displaying text and a view for displaying pictures.

The phone manager is used to provide communication functions of the electronic device 100. Such as management of call status (including on, off, etc.).

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and the like.

The notification manager enables the application to display notification information in the status bar, can be used to convey notification-type messages, can disappear automatically after a short dwell, and does not require user interaction. Such as a notification manager used to inform download completion, message alerts, etc. The notification manager may also be a notification that appears in the form of a chart or scroll bar text at the top status bar of the system, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, prompting text information in the status bar, sounding a prompt tone, vibrating the electronic device, flashing an indicator light, etc.

The Android Runtime comprises a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system.

The core library comprises two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. And executing java files of the application program layer and the application program framework layer into a binary file by the virtual machine. The virtual machine is used for performing the functions of object life cycle management, stack management, thread management, safety and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface managers (surface managers), Media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., OpenGL ES), 2D graphics engines (e.g., SGL), and the like.

The surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications.

The media library supports a variety of commonly used audio, video format playback and recording, and still image files, among others. The media library may support a variety of audio-video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, and the like.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The following describes exemplary workflow of the software and hardware of the electronic device 100 in connection with capturing a photo scene.

When the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into an original input event (including touch coordinates, a time stamp of the touch operation, and other information). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation, and taking a control corresponding to the click operation as a control of a camera application icon as an example, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera drive by calling a kernel layer, and captures a still image or a video through the camera 193.

In the prior art, when a finger with a fingerprint input by a user touches a fingerprint identification area of an electronic device by mistake, the electronic device is unlocked without unlocking intention of the user, so that the possibility of misoperation is increased. The misoperation is specifically an operation that the user does not intend to execute the operation initiated this time, or another operation different from the operation that the user intends to execute.

Fig. 4 is a schematic diagram illustrating a scenario that a smart phone provided by an embodiment of the present application is placed in a bag. The user places the smart mobile phone and other articles in the handbag, and when the user stretches out the hand and turns over in the handbag and look for other articles, the fingerprint identification area of smart mobile phone is touched to the mistake, and at this moment, if the finger that touches the smart mobile phone by mistake is the finger that the user has input the unblock fingerprint, the smart mobile phone can be because of the fingerprint matches the successful unblock to the smart mobile phone. At this time, since the user unlocks the smartphone without the unlocking intention, the user may mistakenly touch an application program or an icon or the like in the unlocked operation interface when finding an object, which may cause a misoperation on the smartphone, such as dialing a phone call of the client or sending a short message to another user, and the like, and may cause an adverse effect on the user.

In another application scenario, the electronic device may be a smart phone. Exemplarily, fig. 5 shows a scene schematic diagram of a smartphone provided in an embodiment of the present application in a certain holding state of a user. The user places the smart phone on the desktop, and need take away the smart phone (the smart phone is in the lock screen state this moment) when the user leaves the desk, when the user used a certain gesture of holding to hold the smart phone, the finger of having typed the unblock fingerprint probably touched the fingerprint identification region of smart phone, and the smart phone can switch to the unblock state from the lock screen state. Because the unlocking operation is an unintentional unlocking behavior of the user, the user does not know that the smart phone is unlocked, and an application program or an icon and the like in an operation interface after unlocking can be touched in the process of holding the smart phone by the user, so that misoperation on the smart phone is caused, and the use experience of the user is reduced.

Illustratively, fig. 6 shows a scene schematic diagram of a smartphone provided in an embodiment of the present application in a state where a user intends to use the smartphone. With reference to the scene diagrams of fig. 4 to 6, it can be determined that, in a state where the user does not intend to unlock, state data of the smartphone, such as a holding state, a moving speed, and an apparatus pose, related to the apparatus, is different from the state data in a state where the user intends to unlock.

The method for preventing unlocking caused by mistaken touch is mainly realized by indicating a user to perform corresponding unlocking intention authentication operation after fingerprint identification and matching, so that the fingerprint unlocking is judged to be intentional unlocking of the user and is not mistakenly touched. Exemplarily, fig. 7 shows a fingerprint unlocking schematic diagram for preventing false touch according to an embodiment of the present application. Referring to fig. 7, when a user presses a fingerprint acquisition area with a finger with entered fingerprint information, if the electronic device detects that the fingerprint matching is successful, the electronic device will not unlock the device immediately, but will display an operation prompt message, for example, "slide up to unlock operation" in the figure, the user may execute corresponding operation according to the operation prompt message, and if the operation initiated by the user matches with the operation specified in the operation prompt message, unlock the device, and identify the intentional unlocking behavior of the user; otherwise, the unlocking operation is identified as unintended unlocking, and the screen locking state of the equipment is maintained. Although the above manner can avoid the false touch behavior of the user, in some scenes, the user cannot complete the corresponding unlocking operation in the operation prompt information, for example, the user holds the smart phone with one hand and holds other objects with the other hand, at this time, the user is in a state of controlling the smart phone with one hand, and the user may be difficult to complete the designated operation, for example, sliding the operation such as a preset distance or a designated track, thereby causing the unlocking failure. Therefore, although the occurrence of the false touch unlocking can be avoided by the operation task of completing the command, the unlocking efficiency of the user is also reduced. In order to solve the problems in the prior art, the fingerprint unlocking method provided by the embodiment of the application can generate the false touch recognition result based on the device state data by collecting the fingerprint information and the device state data during the pressing operation of the user, and does not need to execute the specified unlocking operation by the user every time of the unlocking operation, so that the probability of occurrence of false touch unlocking is reduced, and the unlocking efficiency of the user can be improved.

The first embodiment is as follows:

referring to fig. 8, an executing subject of the fingerprint unlocking method is an electronic device, and the electronic device may be a smart phone, a tablet computer, a computer, or any device configured with a fingerprint identification module. Fig. 8 shows a flowchart of an implementation of a method for unlocking a fingerprint according to an embodiment of the present application, which is detailed as follows:

in S81, if it is detected that the fingerprint identification area has been pressed in the lock screen state, device state data and fingerprint information corresponding to the electronic device at the time of the pressing operation are obtained.

In this embodiment, the electronic device obtains the fingerprint information of the user through the fingerprint acquisition module or the touch screen with the function of identifying the fingerprint under the screen.

In a possible implementation manner, a touch screen built in the electronic device is configured with an underscreen fingerprint identification module, and a fingerprint identification area of the underscreen fingerprint identification module may cover the entire touch screen or be set in a designated area of the touch screen. If the under-screen fingerprint identification module covers the whole touch screen, the fingerprint unlocking process is triggered when a user presses any area of the touch screen in the screen locking state of the electronic equipment; if the under-screen fingerprint identification module is arranged in the designated area of the touch screen, the user needs to press the designated area of the touch screen to trigger the fingerprint unlocking process.

Exemplarily, fig. 9 shows a schematic diagram of a touch operation provided in an embodiment of the present application. Referring to fig. 9, the electronic device includes a touch screen having an off-screen fingerprint recognition function, and a dotted area is used to indicate an effective area where off-screen fingerprint recognition can be implemented. Referring to fig. 9 (a), when the electronic device detects that the pressing operation of the user is in the effective area, the electronic device collects fingerprint information corresponding to the pressing operation and device state data at the current time, that is, executes a fingerprint unlocking process, and performs a false touch identification according to the device state data; referring to fig. 9 (b), when the electronic device detects that the pressing operation of the user is outside the effective area, the electronic device does not collect fingerprint information and device status data at the time of the pressing operation, and recognizes that the user does not need to perform a device unlocking operation.

In this embodiment, when the electronic device detects that the fingerprint identification area has a pressing operation, the fingerprint information corresponding to the fingerprint acquisition area at the pressing operation time may be acquired through the fingerprint acquisition module, and the device state data corresponding to the pressing operation time may also be acquired. The device status data includes, but is not limited to: pose information, time information, pressing position coordinates, moving speed information and the like.

In one possible implementation, the electronic device may have built in motion sensors including, but not limited to: gyroscopes, acceleration sensors, angular velocity sensors, and the like. When the electronic equipment detects that the fingerprint acquisition area has the pressing operation, the offset parameter of the equipment motion to the gyroscope can be determined according to the speed of the angular velocity sensor, and the attitude angle corresponding to the electronic equipment at the pressing operation moment can be determined according to the offset parameter and the deflection quantity of the gyroscope; and determining the motion speed and the motion direction of the electronic equipment according to the speeds fed back by the acceleration sensor and the angular speed sensor. And taking the attitude angle, the movement speed and the movement direction as the equipment state data of the electronic equipment.

In a possible implementation manner, the electronic device may be configured with a pressure sensor in the fingerprint identification area, and the electronic device may obtain, by the pressure sensor, a pressure value corresponding to a time when the pressing operation is performed, and use the pressure value as one of the device state data. Since the larger the pressure value is, the higher the probability that the user intentionally performs fingerprint unlocking is, the pressure value of the pressing operation in the fingerprint identification area can be used as the reference data of the false touch identification.

In a possible implementation manner, the electronic device may obtain, through the proximity sensor, a distance value between the electronic device and an object located closest to the electronic device in the scene when detecting that the fingerprint identification area has a pressing operation, and use the distance value as one item of data in the device state data. For example, in a scenario where the electronic device is placed in a pocket, a distance between the electronic device and an object in the surrounding environment is small, for example, the electronic device may be close to an inner surface of the pocket; and under the scene of normal unlocking, the screen of the electronic equipment is over against the user, a certain distance exists between the screen of the equipment and the user at the moment, and the distance value acquired by the proximity sensor is larger, so that whether the unlocking operation is mistaken touch unlocking or not can be determined according to the distance value. Based on this, the distance value of the proximity sensor can be used as reference data for the false touch recognition.

In a possible implementation manner, when it is detected that the fingerprint identification area has a pressing operation, the electronic device may acquire, through the camera module, a scene image of the electronic device at the pressing operation time, determine, through the scene image, an ambient light intensity corresponding to the pressing operation time and a scene object included in the scene where the electronic device is located, and use the ambient light and the scene object as two items of data in the device state data. Exemplarily, fig. 10 shows a schematic diagram of an unlocking operation provided by an embodiment of the present application. As shown in fig. 10 (a), in a scene where a user intentionally unlocks the device, a screen of the device may face a face of the user, and a scene image acquired by the front camera module may include a face image; referring to fig. 10 (b), if the electronic device is placed in a pocket or a handbag, the user may touch the fingerprint identification area by mistake to trigger the unlocking operation, and the ambient light intensity may be lower than the ambient light intensity in the normal use state (generally, in the normal use state, in the exposed environment, the light intensity is stronger). Based on the reasons, whether the unlocking operation is mistaken touch unlocking or not can be determined in an auxiliary mode through the ambient light intensity and the scene object.

In this embodiment, the fingerprint information may be a fingerprint image or fingerprint feature data extracted based on the fingerprint image. If the fingerprint information is fingerprint feature data, the electronic device can receive a fingerprint image fed back by the fingerprint identification area, analyze the acquired fingerprint image through a preset fingerprint analysis algorithm, and acquire the fingerprint feature data corresponding to the fingerprint image. The fingerprint feature data includes but is not limited to: the fingerprint patterns (for example, a funnel (whorl), an arch (arch), and a loop (loop)), the average distance between the patterns, the number of the patterns, and the like.

In a possible implementation manner, after receiving the fingerprint image fed back by the fingerprint acquisition module, the electronic device can perform image enhancement on the fingerprint image through a preset preprocessing algorithm, so that the accuracy of subsequent fingerprint matching or fingerprint feature data extraction can be improved. The preprocessing algorithm comprises processing means such as contrast enhancement, binarization, graying, sharpness adjustment, brightness adjustment, image noise reduction and the like.

In S82, a fingerprint matching result of the fingerprint information and a standard fingerprint is obtained, and a false touch recognition result is generated according to the unlocking state data recorded in the historical unlocking process and the device state data.

Fingerprint matching process:

in this embodiment, the electronic device may be pre-entered with at least one standard fingerprint. The standard fingerprint may be a standard fingerprint image, or may be standard fingerprint data extracted based on the standard fingerprint image. The manner of acquiring the fingerprint image and extracting the standard fingerprint data may refer to the related discussion of the previous step, which is not described herein again.

In this embodiment, the electronic device may generate a fingerprint matching result according to the matching degree between the fingerprint information acquired by the current acquisition and the standard fingerprint. If the matching degree is larger than a preset matching threshold, outputting a fingerprint matching result which is successfully matched; otherwise, if the matching degree is smaller than or equal to the preset matching threshold, outputting the fingerprint matching result of which the matching fails.

In a possible implementation manner, if the fingerprint information is a fingerprint image, the manner of calculating the matching degree between the fingerprint information and the standard fingerprint may be: the electronic equipment stores a standard image corresponding to a standard fingerprint, takes the standard image as a background image, takes the fingerprint image as a foreground image, performs operations such as rotation and translation on the fingerprint image, calculates the contact ratio between the two images at each position, takes the maximum value of the contact ratio as the matching degree between the two images, and obtains a fingerprint matching result based on the obtained matching degree.

(II) false touch identification process:

in this embodiment, the electronic device may match the device state data with unlocking state data recorded in a historical unlocking process, determine whether the pressing operation is intentional unlocking operation at this time, and determine a false touch recognition result based on the determination result. The false touch recognition result includes but is not limited to: false touch operation and non-false touch operation. The false touch recognition result of the false touch operation indicates that the pressing operation is not the unlocking operation and is used for unlocking behavior triggered unintentionally; the false touch recognition result of the non-false touch operation indicates that the current pressing operation is the unlocking operation and is the unlocking behavior intentionally triggered. The electronic equipment can perform false touch recognition according to the equipment state data. Because equipment state data is gathered in the pressing operation process to need not the user and carry out corresponding intention identification operation, touch the identification process by mistake promptly and be imperceptible to the user, thereby improve the unblock efficiency and improve the convenient degree of unblock. It should be noted that the unlocking state data may be unlocking state data corresponding to an unlocking operation performed locally on the electronic device, or unlocking state data corresponding to an unlocking operation performed in a different place by another device, that is, the electronic device may establish a data synchronization link with the cloud server or another device to obtain unlocking state data of the other device.

In a possible implementation manner, the device state data collected by the electronic device includes an ambient light intensity value and a placement state of the electronic device; in this case, the generating of the false touch recognition result according to the unlocking state data recorded in the historical unlocking process and the device state data may specifically be: if the electronic equipment detects that the ambient light intensity value is smaller than a preset light intensity threshold value and the placement state of the electronic equipment is a preset state, for example, the electronic equipment is in a horizontal placement state, the electronic equipment is identified to be in an idle scene, and the false touch identification result of false touch operation is output; the idle scenes comprise an idle scene placed in the pocket and an idle scene placed in the bag, namely the electronic equipment is placed in the bag or the pocket, and at the moment, the user does not consciously control the electronic equipment, so that the unlocking operation can be recognized as mistaken touch unlocking.

Pressure value of pressing	Range of press coordinate positions	Amount of X-axis deflection	Amount of deflection of Y axis	Amount of Z-axis deflection
					0.5N-2N	(80,160)～(160,160)	50-100	140-160	120-140

TABLE 1

Optionally, the electronic device may configure corresponding false touch weights for different state dimensions, and when the electronic device may calculate the matching degree between the device state data and the unlock state data, the electronic device may count the number of the matched state dimensions, and calculate the matching degree based on the false touch weights corresponding to the state dimensions. For example, the press pressure value has a false touch weight of 0.5, the press coordinate position has a false touch weight of 0.2, and the deflection amount corresponding to each coordinate axis has a false touch weight of 0.1. If the state dimensions matched with the state data of a certain device are the pressing coordinate position, the X-axis deflection and the Y-axis deflection, the corresponding matching degree is calculated as follows: 0.2+0.1+0.1 ═ 0.4.

In one possible implementation manner, the manner of generating the false touch recognition result based on the device status data may be: the electronic device may obtain a plurality of status data of the user during the use of the device, including but not limited to: the state data corresponding to the unlocking operation, the state data of the electronic equipment in the walking state, the state data in the video scene watched through the electronic equipment, the state data in the call state and the like. The electronic device can configure corresponding state labels for different state data, and train a preset classification model based on all the state labels and the state data to obtain a state classification model which can be used for identifying whether the state classification model is in an unlocking state. The electronic equipment can import the equipment state data into the state classification model, identify the state label corresponding to the equipment state data, and identify whether the pressing operation of the user is mistakenly touched according to the state label. As described above, the status tag may include: unlocking operation state, walking state, video watching state and conversation state. As for the call state and the walking state, the electronic equipment is usually not allowed to be operated, and if the electronic equipment identifies that the equipment state data belongs to any state label, an operation identification result of the false touch operation is output; for the unlocking operation state and the video watching state, the electronic equipment is often required to be in a screen opening state, and if the electronic equipment identifies that the equipment state data belongs to any one of the state tags, an operation identification result of non-error touch operation is output.

(III) regarding the sequence of the execution of the fingerprint matching process and the false touch identification process:

in this embodiment, the electronic device may execute the two operations at the same time, that is, the electronic device may invoke two asynchronous processes, where one process is used to respond to the fingerprint matching operation and the other process is used to respond to the false touch recognition operation. Of course, the electronic device may also execute the two operations based on a preset execution sequence, for example, perform fingerprint matching first, and then perform false touch recognition based on the device status data; or the false touch identification is carried out firstly, and then the matching is carried out with the standard fingerprint based on the fingerprint information.

In this embodiment, based on the difference between the fingerprint matching result and the false touch recognition result, the following three different response operations can be handled. If the electronic device detects that the fingerprint matching result is a successful match (i.e., the fingerprint information matches the standard fingerprint) and the false touch identification result is a false touch operation, then the operation of S83 is executed; if the electronic device detects that the fingerprint matching result is a successful match (i.e. the fingerprint information matches the standard fingerprint) and the false touch identification result is a non-false touch operation, then the operation of S84 is executed; if the electronic device detects that the fingerprint matching result is a matching failure, the operation of S85 is executed regardless of whether the false touch recognition result is a false touch operation. In this embodiment, the execution order between the fingerprint matching result and the false touch recognition result does not have a certain sequence, and the electronic device needs to obtain the two recognition results and then execute the response determination process.

In S83, if the fingerprint matching result is a successful match and the false touch recognition result is a false touch operation, the screen lock state is maintained.

In this embodiment, if the fingerprint matching is successful, it indicates that the user performing the pressing operation at this time is an entered legal user, and identifies that the unlocking operation is legal, and since the false touch identification result is a false touch operation, it indicates that the user does not intentionally perform the unlocking operation, and belongs to a false touch unlocking behavior. The screen locking state is specifically a limited operation state of an interactive control of the electronic device, and only specified operations can be executed, such as screen lighting, password unlocking, fingerprint unlocking, and the like.

In S84, if the fingerprint matching result is a successful match and the false touch recognition result is a non-false touch operation, an unlocking operation is performed.

In this embodiment, if the fingerprint matching is successful, it indicates that the user performing the pressing operation is a logged-in legitimate user, and identifies that the unlocking operation is legitimate, and the false touch identification result is a non-false touch operation, and indicates that the user intends to unlock the electronic device, at this time, the unlocking operation may be performed on the electronic device, that is, the electronic device may be changed from the screen-locked state to the unlocked state. The unlocking state is specifically an unlimited operation state of an interactive control of the electronic device, and may be, for example, a sliding operation on a sliding screen, and an operation on an application program, a control, and the like on an operation interface.

Further, as another embodiment of the present application, after S84, the method may further include:

in S841, the unlocking state data corresponding to the unlocking operation is generated, and the unlocking state data is used to determine a false touch recognition result.

In this embodiment, when the electronic device detects that the current unlocking operation is an unlocking operation of the user without a wrong touch, the electronic device performs a result on the device intentionally. Accordingly, the electronic device may acquire the unlock state data corresponding to the unlock operation through each sensor in the electronic device, or may directly use the device state data acquired in S81 as the unlock state data corresponding to the unlock operation. The unlocking state data are stored in the unlocking state database related to historical unlocking operation, so that in the daily unlocking process of a user, sample data in the unlocking state database can be continuously increased, automatic collection of the sample data can be realized, the operation behavior of the user can be updated, and the accuracy of mistaken touch identification is improved.

In a possible implementation manner, when the electronic device generates the unlock state data, a corresponding time tag may be configured for the unlock state data. The smaller the difference between the time tag and the time of performing the false touch recognition operation is, the higher the corresponding weighting weight is, and the weighting weight is used for contribution effect in the subsequent generation of the false touch recognition result.

For example, if the electronic device specifically obtains the unlocking characteristic value based on all the unlocking state data when recognizing the false touch recognition result, in this case, the unlocking characteristic value may be obtained by superimposing according to each unlocking state data and the weighting weight. The specific calculation formula is as follows:

wherein, Unlocked_iAn unlocking characteristic value of the ith state dimension; time_jA weighted weight corresponding to the jth unlock state data, the additionThe weight is determined based on the difference between the time label of the unlocking state data and the time of the false touch recognition operation; hislocked_ijThe parameter value of the ith state dimension in the jth unlocking state data; m is the total number of the unlocking state data; n is the total number of state dimensions.

For example, when the electronic device identifies the false touch identification result, specifically, the matching number of the unlocking state data and the device state data is counted, and the unlocking probability corresponding to the device state data is obtained based on the matching number, so that the false touch identification result is generated based on the unlocking probability. In this case, when the unlocking probability is calculated according to the matching number, weighted superposition may be performed according to the weighted weights associated with the unlocking state data that are matched with the device state data, so as to obtain the unlocking probability.

Since the usage habit of the user may change over time during the usage of the electronic device. The smaller the difference between the time tag and the time of performing the false touch recognition operation is, namely the closer the difference is to the current time, the more similar the current unlocking habit of the user using the electronic equipment is, the higher the weighting weight is configured, so that the contribution of the latest unlocking habit of the user to the false touch recognition can be increased, the judgment logic of the false touch recognition can be updated along with the operation habit of the user, and the accuracy of the false touch recognition is improved.

In S85, if the fingerprint matching result is a match failure, the lock screen state is maintained.

In this embodiment, if the fingerprint matching fails, it indicates that the user performing the pressing operation is not an entered legal user, and no matter whether the unlocking operation is an intentional unlocking behavior, the device does not need to be unlocked, and the electronic device may maintain the screen locking state at this time.

In the embodiment of the application, when a user presses a fingerprint identification area, the electronic device acquires fingerprint information and also acquires device state data corresponding to the pressing operation moment, the device state data is compared with unlocking state data corresponding to a conventional unlocking process of the user based on the device state data, the device state data is compared with the unlocking state data corresponding to the conventional unlocking process of the user, a false touch identification result is obtained based on the comparison result, identification of a false touch event is achieved, a screen locking state is maintained when the false touch operation is determined, the possibility of false operation is reduced, and the use experience of the user is improved.

Example two:

different from the first embodiment, in the present embodiment, the manner of generating the false touch recognition result according to the unlocking state data recorded in the historical unlocking process and the device state data is specifically as follows: and determining the unlocking probability of the intentional unlocking operation of the user at this time by counting the number of unlocking state data matched with the collected equipment state data at this time, and obtaining a false touch recognition result based on the unlocking probability.

Fig. 12 shows a flowchart of an implementation of a method for unlocking a fingerprint according to a second embodiment of the present application, which is detailed as follows:

in S121, if it is detected that the fingerprint identification area has a pressing operation in the screen lock state, device state data and fingerprint information corresponding to the electronic device at the time of the pressing operation are obtained.

In S122, a fingerprint matching result of the fingerprint information with a standard fingerprint is obtained.

In S123, the number of matches of the unlock state data that matches the device state data is counted from the unlock state data of all the historical unlock operations.

In this embodiment, the unlocking state data may be unlocking state data acquired when the electronic device performs an unlocking operation in a use process, or may be unlocking state data about other electronic devices acquired from the cloud server. In particular, in an initial use stage of the electronic device (the initial use stage may be determined based on a use duration, for example, if the use duration is less than a preset duration threshold, the initial use stage is identified as the initial use stage; the initial use stage may also be determined based on an unlocking frequency, for example, if the number of times of the unlocking operation performed by the electronic device is less than a preset unlocking frequency threshold, the terminal device is identified as the initial use stage), the unlocking state data may be downloaded from the cloud server; on the contrary, if the electronic device is not in the initial stage of use, the unlocking state data acquired locally can be used,

in a possible implementation manner, the electronic device may perform discrete statistical analysis on unlocking state data of all historical unlocking operations to obtain a plurality of unlocking behavior types. Each unlocking behavior type corresponds to a state parameter interval, and the state parameter interval can be determined and obtained according to all unlocking state data belonging to the unlocking behavior type. For example, the electronic device may perform cluster analysis on all unlocking state data to obtain a plurality of unlocking clustering centroids, and determine the state parameter interval according to the unlocking clustering centroids and the effective centroid range. And marking a coverage space corresponding to each unlocking behavior type on a preset coordinate system according to the unlocking clustering mass center and the effective mass center range, and determining the unlocking behavior type of the unlocking state data based on the coverage space in which the unlocking state data falls on the coordinate system, so that the unlocking times of each unlocking behavior type can be obtained through statistics. Table 2 shows a statistical information table of unlocking behavior types provided in an embodiment of the present application. Referring to table 2, the unlock state data includes five state dimension parameters, which are the identification trigger region, the pressing pressure value of the pressing operation, and the attitude angle of the current electronic device (the attitude angle may be determined by the offset from the three-dimensional coordinate axis). Of course, the above state dimension may also include: unlocking time, information of the current position of the user, the movement speed and the movement direction of the equipment and the like. The pressing area may be determined according to a coordinate point of the pressing operation, or the fingerprint identification area of the electronic device may be divided into a plurality of identification trigger areas, and a parameter value corresponding to the identification trigger area is determined based on a number of the identification trigger area into which the pressing operation falls. Exemplarily, fig. 13 shows a schematic diagram of dividing a trigger area according to an embodiment of the present application. Referring to fig. 13, the fingerprint acquisition area of the electronic device covers the whole screen, the screen is divided into 12 areas according to the preset grid size, corresponding numbers are configured for the fingerprint acquisition areas, and then parameter values of dimensions of the "identification trigger area" in the unlocking state parameters corresponding to the unlocking operation can be determined according to the area acted by the pressing operation. If the pressed identification trigger area in fig. 11 is 8, the parameter value of the dimension of the "identification trigger area" in the unlock state data corresponding to the unlocking operation is "8".

TABLE 2

In a possible implementation manner, the electronic device may configure corresponding associated offsets for each state dimension included in the device state data. And if the difference value between the parameter value of each state dimension in the unlocking state data of the historical unlocking operation and the parameter value of the corresponding state dimension in the equipment state parameters is smaller than the correlation offset, identifying that the equipment state data is matched with the unlocking state data, so that the matching number of the unlocking state data matched with the equipment state data can be obtained. For example, the device state data includes three state dimensions of recognition trigger coordinates, a press pressure value and an attitude angle, the associated offset corresponding to each state dimension is (± 15), (± 1), (± 30 °), the device state parameter acquired at this time is specifically ([15,20], 5, 100 °), the unlock state data of the device state parameter needs to be (the distance from the point [15,20] is less than or equal to 15), the press pressure value is (4-6), and the attitude angle is (70 ° -130 °). And if the unlocking state data corresponding to the historical unlocking operation is ([15,21], 5 and 110 degrees) and the difference value between each state dimension of the equipment state parameter is smaller than the associated offset, identifying the unlocking state data as being matched with the equipment state data. If the unlocking state data corresponding to the historical unlocking operation is ([15,21], 1, 110 °), the unlocking state data is identified to be not matched with the device state data because the difference value between the pressing pressure dimension and the pressing pressure value of the device state data is greater than the associated offset.

In S124, an unlocking probability is determined based on the matching number, and the false touch recognition result is obtained according to the unlocking probability and a preset unlocking determination threshold.

In this embodiment, if the number of the unlocking state data matched with the device state data is larger, the corresponding unlocking probability is larger, which indicates that the present pressing operation is the intentional unlocking operation; conversely, if the number of unlocking state data matches the device state data is smaller, the corresponding unlocking probability is smaller, indicating that the present pressing operation is not an intentional unlocking operation.

In a possible implementation manner, the manner of determining the unlocking probability based on the matching number may be: and calculating the ratio of the matching number to the total number of all unlocking state data, and determining the unlocking probability based on the ratio. For example, the total number of the unlock state data is 30, the number of the unlock state data matched with the device state data collected this time is 15, the ratio of the two is 50%, the 50% may be used as the unlock probability, and a corresponding adjustment weight, for example, 1.5, may be configured for the ratio, so that the final unlock probability is 50% × 1.5 — 75%.

In a possible implementation manner, the electronic device matches the matching number with each preset reference range, and obtains a corresponding unlocking probability based on a matching result. Table 3 shows a correspondence table of the unlocking probability. Referring to table 3, the electronic device sets a correspondence table of a plurality of reference ranges, and the correspondence table configures corresponding unlocking probabilities for different reference ranges. And determining the unlocking probability corresponding to the equipment state data according to the matching number obtained by the statistics.

Range of number of matches	Probability of unlocking
		0～5	20％
6～15	60％
		15～+∞	100％

TABLE 3

In this embodiment, the electronic device may obtain the false touch recognition result according to the unlocking probability obtained by the current recognition and the comparison result between the preset unlocking determination thresholds. Specifically, if the unlocking probability is greater than or equal to the unlocking judgment threshold, generating a false touch recognition result of non-false touch operation; otherwise, if the unlocking probability is smaller than the unlocking judgment threshold, generating a false touch recognition result of the false touch operation.

In S125, if the fingerprint matching result is a successful match and the false touch identification result is a false touch operation, the screen locking state is maintained.

Further, as another embodiment of the present application, S125 may specifically include:

in S1253, if the unlocking probability is smaller than the unlocking determination threshold, unlocking prompt information is output.

In this embodiment, when the electronic device detects that the unlocking probability is smaller than the preset unlocking determination threshold, it needs to further determine whether the user has an unlocking intention, so that an unlocking prompt message is output. The unlocking prompt information is specifically used for prompting the user to execute the corresponding intention authentication operation. The above intent authentication operations include, but are not limited to: pressing a designated area, sliding a specific distance in a designated direction, or drawing a designated sliding trajectory. Fig. 14 shows schematic diagrams of three unlocking prompt messages provided in an embodiment of the present application. Referring to fig. 14, the prompt information in (a) in fig. 14 is a region designated for pressing; here, the designated pressing area may be an area different from the pressing operation initiated in S121, and in particular, may be another area having a distance greater than a preset threshold from the pressing operation initiated in S121. The prompt information in (b) of fig. 14 is to prompt the user to slide a specified distance in the horizontal direction. The prompt information in (c) in fig. 14 is to prompt the user to draw a "Z" -shaped slide trajectory.

Different from the prior art, the electronic device does not need the user to perform the intention authentication operation every time the electronic device performs the unlocking operation, and only when the unlocking probability is detected to be smaller than the unlocking determination threshold value, the user is required to perform the intention authentication operation, and when the unlocking probability is detected to be larger than or equal to the unlocking determination threshold value, the intention authentication operation is not required. That is, only when it is determined that the user is likely to perform the false touch operation this time, the intention authentication operation needs to be performed, so as to further improve the accuracy of the false touch recognition, and avoid the situation that the user cannot unlock the electronic device when the user has an unlocking intention.

In S1254, if the first touch operation matched with the unlocking prompt information is not received within the preset effective response time, the screen locking state is maintained.

In this embodiment, after the electronic device outputs the unlocking prompt information, a preset operation monitoring timer is started, and the screen is kept in a lighting state in the detection process, so as to collect the touch operation of the user. If the count value of the operation timer is greater than the effective response time and the touch operation initiated by the user is not received or the touch operation initiated by the user is not matched with the unlocking prompt message, executing the operation of S1254; and if the touch operation which is initiated by the user and matched with the unlocking prompt information is received when the count value of the operation timer is less than or equal to the effective response time, executing the operation of S1255.

In this embodiment, the receiving no first touch operation matching with the unlocking prompt message includes: the user does not initiate any touch operation within the effective response time, and the touch operation initiated by the user within the effective response time is not matched with the unlocking prompt information. The touch operation matched with the unlocking prompt information specifically comprises the following steps: and touch operation, wherein the operation deviation between the standard operations corresponding to the unlocking prompt information is smaller than a preset deviation threshold value. The operation deviation may be specifically determined according to a type of a standard operation indicated by the unlocking prompt information, for example, if the operation type of the standard operation is a click operation, the operation deviation is specifically a distance value between the operation deviation and a specified coordinate of the click operation; if the operation type of the standard operation is a sliding operation in a specified direction, the operation deviation is specifically a vector included angle between the operation type and the specified direction; if the operation type of the standard operation is to draw a specified sliding track, the operation deviation is specifically a deviation amount from the specified sliding track.

Exemplarily, fig. 15 shows an acquisition schematic diagram of a first touch operation provided in an embodiment of the present application. Referring to (a) in fig. 15, in order to determine whether the user has an unlocking intention, the electronic device displays a prompt message drawing a "Z" -shaped sliding trajectory on the touch screen. If the user intentionally unlocks, the electronic device may acquire a first touch operation with a higher similarity to the "Z" shape, as shown in (b) of fig. 15; on the contrary, if the user does not intend to illustrate the lock, the sliding track corresponding to the first touch operation collected by the electronic device may have a larger difference from the "Z" shaped sliding track, as shown in fig. 15 (c), and at this time, the electronic device may recognize that the first touch operation matching with the unlocking prompt information is not received.

Exemplarily, fig. 16 shows an acquisition schematic diagram of a first touch operation provided in another embodiment of the present application. Referring to (a) of fig. 16, in order to determine whether the user has an unlocking intention, the electronic device displays a prompt message sliding in an upward direction to a preset position on the touch screen. If the user intends to unlock, the electronic device may acquire a first touch operation moving from the pressing area to the designated area, as shown in (b) of fig. 16; on the contrary, if the user does not intend to illustrate the lock, the first touch operation collected by the electronic device is not the movement track of the preset position, as shown in fig. 16 (c), and at this time, the electronic device recognizes that the first touch operation matched with the unlocking prompt information is not received.

Exemplarily, fig. 17 shows an acquisition schematic diagram of a first touch operation provided in another embodiment of the present application. Referring to (a) of fig. 17, in order to determine whether the user has an unlocking intention, the electronic device clicks a prompt message of a designated area on the touch screen. If the user intends to unlock, the electronic device may acquire a pressing operation of the designated area, as shown in (b) of fig. 17; on the contrary, if the user does not intend to illustrate the lock, the electronic device may recognize that the first touch operation matched with the unlocking prompt information is not received when the first touch operation acquired by the electronic device is not the pressing operation in the designated area, as shown in fig. 17 (c).

In this embodiment, when the user cannot initiate the first touch operation matched with the unlocking prompt information within the effective response time, it indicates that the unlocking operation of the user is an unintended unlocking operation, and at this time, the device is maintained in the screen locking state.

In S1255, if the first touch operation matched with the unlocking prompt information is received within the valid response time, an unlocking operation is performed.

In this embodiment, when the user initiates a touch operation matched with the standard operation corresponding to the unlocking prompt information within the effective response time, it is recognized that the unlocking operation is the intended unlocking operation of the user, and the electronic device is unlocked at this time.

In the embodiment of the application, when the unlocking probability is detected to be low, namely, when the false touch recognition result is the false touch operation, the prompt unlocking prompt information is generated so as to further confirm the unlocking intention of the user, and therefore the accuracy of false unlocking recognition is improved.

Further, as another embodiment of the present application, before S1253, the method further includes:

in S1251, a last historical pressing time corresponding to a historical pressing operation successfully matched with the standard fingerprint is acquired, and a pressing interval is determined based on the historical pressing time and the pressing operation time.

In this embodiment, when the electronic device outputs the false touch recognition result, the unlocking determination threshold may be dynamically adjusted according to a pressing interval of the pressing operation by the user. The history pressing operation of the previous fingerprint matching success specifically comprises the following steps: and another historical pressing operation which is closest to the pressing operation initiated by the user in the fingerprint identification area at the time is performed from all the historical pressing operations of which the collected fingerprint information is matched with the standard fingerprint. The electronic device may record the trigger time of each pressing operation, that is, the historical pressing time, and calculate a time difference between the historical pressing time corresponding to the historical pressing operation that was successfully matched with the standard fingerprint last time and the time of the pressing operation initiated this time, to obtain the pressing interval. For example, if the user triggers a pressing operation in the fingerprint identification area at 14:10:15, the first historical pressing time when the user last initiated the first pressing operation (but the fingerprint matching was unsuccessful) is 14:10:13, the second historical pressing time when the user initiated the second pressing operation initiated the second time close to the current time (the fingerprint matching was successful) is 14:10:10, and the first pressing operation does not match the standard fingerprint, the pressing interval is calculated by calculating the pressing interval from the second historical pressing time of the second pressing operation and the pressing operation time of the pressing operation initiated this time, that is, 14:10:15-14:10:10 is 5s, and the pressing interval corresponding to the pressing operation this time is 5 s.

In one possible implementation, in order to reduce the storage pressure of the database, the electronic device may configure the maximum storage duration for the time tag of each pressing operation, for example, 60 s. The electronic device may configure a timer for an operation record corresponding to each pressing operation, where the operation record includes a historical pressing time corresponding to the pressing operation. And if the count value of the timer of any operation record is detected to be larger than the maximum storage time length, deleting the operation record. Therefore, if the pressing interval between two pressing operations of the user is greater than 60s, the corresponding operation record of the last pressing operation does not exist in the current pressing operation, and at this time, if it is detected that the current pressing operation does not have the associated last pressing operation, the pressing interval is configured to be a default value, for example, 60 s.

In S1252, the unlock determination threshold is configured based on the press interval.

In this embodiment, the electronic device may determine the unlocking determination threshold used in the false touch recognition process according to the pressing interval. This unblock is judged the threshold value and is used for judging this time to press the operation and whether to touch the operation for the mistake, specifically: if the unlocking probability is greater than or equal to the unlocking judgment threshold, obtaining a false touch identification result of non-false touch operation; and otherwise, if the unlocking probability is smaller than the unlocking judgment threshold, obtaining a false touch identification result of the false touch operation. Wherein, if the shorter the pressing interval is, the smaller the numerical value of the corresponding unlocking judgment threshold value is; conversely, the longer the pressing interval, the larger the numerical value of the corresponding unlock determination threshold. Because the user presses the fingerprint identification area for many times in a short time interval, and the acquired fingerprint information is matched with the standard fingerprint, the identification user has stronger unlocking intention at the moment. Based on the unlocking judgment method, the electronic equipment can reduce the unlocking judgment threshold value corresponding to the non-error touch operation, so that the occurrence probability that the unlocking cannot be successfully performed due to the fact that the equipment state corresponding to the unlocking operation is inconsistent with the unlocking state obtained in the history due to the change of the operation habit under the condition that the unlocking intention exists is reduced.

In one possible implementation manner, the electronic device may be divided into a plurality of pressing interval regions, and corresponding unlocking determination threshold values are divided for different pressing interval regions. Alternatively, if there are only two pressing interval regions, that is, two intervals greater than a certain interval threshold and less than or equal to the certain interval threshold, the electronic device may compare the pressing interval with the interval threshold, and determine the unlocking determination threshold based on the comparison result. For example, the pressing interval is divided into two intervals, which are greater than 5s or less than or equal to 5s, and each pressing interval area is configured with a corresponding unlocking determination threshold, for example, a pressing interval greater than 5sThe unlocking determination threshold value configured in the interval is T_α1The unlock determination threshold value of the pressing interval of 5s or less is T_α2。

In one possible implementation, the electronic device may establish a transfer function between the press interval and the unlock determination threshold, e.g., T_αF (break), where T_αThe break is the pressing interval for the unlock determination threshold. Alternatively, the pressing interval is inversely proportional to the unlock determination threshold.

In S126, if the fingerprint matching result is a successful match and the false touch identification result is a non-false touch operation, an unlocking operation is performed.

Further, as another embodiment of the present application, after S126, the method further includes:

in S1261, the unlock state data corresponding to the unlock operation is generated, and the unlock state data is used to determine a false touch recognition result.

Further, as another embodiment of the present application, after S1261, the method further includes:

in S1262, a second touch operation initiated by the user on the electronic device is monitored, and the valid identifier corresponding to the unlocking state data is configured based on the second touch operation.

In this embodiment, after the electronic device is unlocked, a second touch operation initiated by the user on the electronic device may be acquired, where the touch operation includes but is not limited to: the method comprises the steps of performing touch screen operation on a screen, performing pressing operation on keys on the electronic equipment and the like. In a possible implementation manner, the electronic device may configure a monitoring duration for a monitoring process of the second touch operation, that is, collect all touch instructions initiated by the user within the monitoring duration from the unlocking time of the electronic device, that is, serve as the second touch operation. It should be noted that, if the user does not initiate any touch operation within the monitoring duration, the second touch operation may be null.

In this embodiment, the operation behavior of the acquired second touch operation is analyzed, so as to determine whether the second touch operation is a intentionally initiated touch operation of the user, and configure an effective identifier corresponding to the unlocking state based on the intention recognition result. Specifically, if the second touch operation is an unintended touch operation, identifying the unlock state data as invalid unlock data, and configuring a valid identifier; on the contrary, if the second touch operation is the intentional touch operation, the unlocking state data is necessarily valid unlocking data, and a valid identifier is configured.

In a possible implementation manner, if the second touch operation is null, that is, the user does not initiate any touch operation within the monitoring duration, the valid identifier of the unlock state data is configured as the first bit value. And when the valid identifier is a first bit value, identifying the unlocking state data as invalid unlocking state data. If the user needs to unlock the equipment, the user often needs to perform related operations on the equipment, and the user does not perform any operation after unlocking, the unlocking operation can be identified as mistaken touch unlocking and not intentional unlocking operation.

In a possible implementation manner, if the second touch operation is specifically a click operation, and the click coordinates corresponding to all the click operations in the monitoring duration do not have an operable display object on the display interface, for example, an icon of an application program or an operable control is not included, but an inoperable display object such as a background picture is displayed. At this time, the electronic device recognizes the second touch operation as an unintended touch operation, and configures the valid identifier of the unlock state data as a first bit value.

The manner of configuring the valid identifier of the unlock state data according to the second touch operation may be:

mode one (determining valid identifier based on coordinate offset):

1. if the second touch operation is a click operation on any display object in a display interface, calculating an offset between a click coordinate of the click operation and a center coordinate of the display object;

2. if the offset is larger than a preset offset threshold, configuring the effective identifier of the unlocking state data into a first bit value; when the valid identifier is a first bit value, identifying the unlocking state data as invalid unlocking state data;

3. if the offset is smaller than or equal to the offset threshold, configuring the valid identifier of the unlocking state data as a second bit value; and when the effective identifier is a second bit value, identifying the unlocking state data as effective unlocking state data.

In this embodiment, if the second touch operation initiated by the user after the unlock state is a click operation, a click coordinate corresponding to the click operation on the display interface may be obtained. Since a certain contact area exists between a finger of the user initiating the click operation and the touch screen, that is, the click operation of the user corresponds to a click area, the coordinate of the geometric center of the click area can be used as the click coordinate. The electronic equipment can identify the display object indicated by the clicking operation, acquire the corresponding center coordinate of the display object on the display interface, calculate the offset between the clicking coordinate and the center coordinate, and judge whether the clicking operation is the intentional clicking operation or not based on the offset. The display object is specifically an operable object in the display interface, such as a virtual key, a dialog box, an information prompt box, an application icon, an input box, and the like.

Illustratively, fig. 18 shows a schematic diagram of an offset between a click operation and a display object provided by an embodiment of the present application. Referring to fig. 18, a display object indicated by a click operation initiated by a user is an application program 1, and the electronic device may obtain a click coordinate of the click operation and a center coordinate of a corresponding icon of the application program 1 in a display interface, calculate a distance value between the two coordinates, and use the distance value as the offset.

Illustratively, fig. 19 shows a schematic diagram of a click operation provided by an embodiment of the present application, where an offset threshold of the electronic device is x. Referring to fig. 19 (a), after the electronic device is unlocked, a click operation of the user on the application program 1 is detected, and an offset between the click operation and the center coordinate of the application program 1 is z, where z is less than x, at this time, the electronic device recognizes that the user is intentionally performing the click operation, and thus recognizes that the unlock state data is valid data and is set as a second bit value.

Referring to fig. 19 (b), after the electronic device is unlocked, a click operation of the user on the application program 1 is detected, and an offset between the click operation and the center coordinate of the application program 1 is y, where y > x, and at this time, the electronic device recognizes that the user performs the click operation unconsciously, and thus recognizes that the unlocked state data is invalid data, and sets the data to be the first bit value.

Referring to (c) of fig. 19, after the electronic device is unlocked, a click operation of the user on the current interface is detected, and the click operation does not have a corresponding application program or valid control, at this time, the user is identified as an unintentional click operation, and therefore, the unlock state data is identified as invalid data and is set as a first bit value.

In this embodiment, if the offset amount is greater than the preset offset threshold, it is recognized that the user may not click the display object under an intentional condition, and at this time, the valid identifier is configured as the first bit value, that is, the unlock state data is recognized as invalid unlock data. Otherwise, if the offset is less than or equal to the offset threshold, it is recognized that the user clicks the display object under the intentional condition, and at this time, the valid identifier is configured as a second bit value, that is, the unlock state data is recognized as valid unlock data. The electronic equipment can obtain the false touch recognition result of the equipment state data through the effective unlocking state data. Alternatively, the electronic device may delete invalid unlock state data.

Mode two (determination of valid flag based on amount of sliding track deviation):

1. if the touch operation is a sliding operation, calculating the deviation amount between the sliding track of the sliding operation and the standard track;

2. if the deviation amount is larger than a preset deviation threshold value, configuring the effective identifier of the unlocking state data into a first bit value; when the valid identifier is a first bit value, identifying the unlocking state data as invalid unlocking state data;

3. if the deviation amount is smaller than or equal to the deviation threshold value, configuring the valid identifier of the unlocking state data as a second bit value; and when the effective identifier is a second bit value, identifying the unlocking state data as effective unlocking state data.

In this embodiment, if the second touch operation initiated by the user after the unlock state is a sliding operation, a sliding track corresponding to the current click operation on the display interface may be obtained. The electronic device can identify the sliding type corresponding to the sliding track, and compare the sliding track with the standard track of the corresponding sliding type to obtain the deviation amount. The slide type may be divided based on the direction of the slide trajectory, such as an upward slide, a leftward slide, a downward slide, and an upward slide; the sliding type may also be divided according to a trajectory shape of the sliding trajectory, for example, a straight shape, a circular shape, a Z-shape, or the like. The deviation amount may be the length of a non-overlapping portion between two tracks, or an included angle between two tracks.

Illustratively, fig. 20 shows a schematic diagram of the deviation amount between the sliding operation and the standard trajectory provided by an embodiment of the present application. Referring to fig. 20, the sliding operation initiated by the user is sliding to the right, and a sliding angle of the sliding to the right and the standard track have a certain included angle, which can be taken as a deviation amount between the two sliding tracks.

Exemplarily, fig. 21 shows a schematic diagram of a sliding operation provided by an embodiment of the present application, where a deviation angle of the electronic device is x. Referring to fig. 21 (a), after the electronic device is unlocked, it is detected that the user has initiated a rightward sliding operation, an included angle between the rightward sliding operation and the horizontal rightward direction is z, and z is less than x, at this time, the electronic device recognizes that the user intentionally performs the sliding operation, and thus recognizes that the unlock state data is valid data, and sets the unlock state data as a second bit value.

Referring to fig. 21 (b), after the electronic device is unlocked, it is detected that the user has initiated a rightward sliding operation, an included angle between the rightward sliding operation and the horizontal rightward direction is y, and y is greater than x, at this time, the electronic device recognizes that the user has performed an unintentional sliding operation, and thus recognizes that the unlock state data is invalid data, and sets the unlock state data as a first bit value.

Referring to (c) in fig. 21, after the electronic device is unlocked, the sliding operation of the user on the current interface is detected, but the direction of the sliding operation cannot be identified, and there is no preset gesture matching with the sliding operation, at this time, the user is identified as an unintended sliding operation, and therefore, the unlocking state data is identified as invalid data and is set as the first bit value.

Illustratively, fig. 22 shows a schematic diagram of a sliding operation provided by another embodiment of the present application, where an effective sliding length of the electronic device is l, and a deviation angle threshold is x. As shown in (a) in fig. 2, after the electronic device is unlocked, it is detected that the user initiates a rightward sliding operation, and a distance t of the rightward sliding operation is obtained, where t is greater than l, at this time, an included angle z between the rightward sliding operation and the horizontal right is determined, and if the included angle z is less than x, the electronic device recognizes that the user performs the sliding operation with intent, and thus recognizes that the unlocking state data is valid data, and sets the unlocking state data as a second bit value.

Referring to fig. 22 (b), after the electronic device is unlocked, it is detected that the user initiates a rightward sliding operation, and a distance s of the rightward sliding operation is obtained, where s is greater than l, at this time, an included angle y between the rightward sliding operation and the horizontal rightward direction is determined, and if the included angle y is greater than x, at this time, the electronic device recognizes that the user performs an unintentional sliding operation, and thus, the unlocked state data is recognized as invalid data and is set as a first bit value.

Referring to (c) in fig. 22, after the electronic device is unlocked, it is detected that the user initiates a rightward sliding operation, and a distance q of the rightward sliding operation is obtained, where q is less than l, and at this time, no matter whether an included angle between the rightward sliding operation and the horizontal rightward is less than x, the electronic device recognizes that the user performs the sliding operation unconsciously, and thus recognizes that the unlock state data is invalid data, and sets the unlock state data to be a first bit value.

Therefore, whether the recognition operation is a valid operation can be determined by a plurality of feature quantities, for example, by the moving distance of the sliding track, the angle with the standard direction, the similarity with the standard sliding track, and the like, and if the plurality of feature quantities are all within the preset valid feature range, the touch operation is recognized as a valid operation.

In a possible implementation manner, the number of the second touch operations may be multiple, in this case, the electronic device may collect multiple continuous touch operations of the user, respectively execute the effective determination process, and determine the effective identifier of the unlocking state data based on effective identification results of the multiple touch operations.

In this embodiment, if the deviation amount is greater than the preset deviation threshold, it is recognized that the user may not generate the sliding track under an intentional condition, and at this time, the valid flag is configured as the first bit value, that is, the unlock state data is recognized as invalid unlock data. On the contrary, if the deviation amount is less than or equal to the deviation threshold, it is recognized that the user generates the sliding track under the intentional condition, and at this time, the valid identifier is configured as the second bit value, that is, the unlock state data is recognized as valid unlock data. The electronic equipment can obtain the false touch recognition result of the equipment state data through the effective unlocking state data. Alternatively, the electronic device may delete invalid unlock state data.

It should be noted that S1253 to S1255 are used for determining the unlocking intention of the user; and step S1262 is also for determining the unlocking intention of the user. I.e. the two embodiments described above need to achieve similar technical effects. Therefore, if S125 in the second embodiment is implemented by specifically using S1253 to S1255, S126 may not include S1262 thereafter; if S1262 is included after S126 in the second embodiment, S125 may be implemented without using S1253 to S1255.

Further, as another embodiment of the present application, after S1262, the method may further include:

in S1263, if the valid identifier of the unlock state data is the first bit value, a screen lock operation is performed.

In this embodiment, if it is detected that the second touch operation performed by the user after the unlock state is an unintended unlock behavior and the valid identifier of the unlock state data is configured as the first bit value, the screen lock operation may be performed on the electronic device again, so that the user is prevented from continuing to perform the unintended false touch behavior, and the influence of the false touch behavior is reduced.

In S127, if the fingerprint matching result is a matching failure, the lock screen state is maintained.

In the embodiment of the application, the matching number between the acquired equipment state data and the unlocking state data of historical unlocking operation is counted, so that whether the habit of pressing the fingerprint identification area is consistent with the historical unlocking behavior or not can be judged, whether the pressing operation is mistaken touch operation or not is identified, the mistaken touch identification is identified, the screen locking state is kept when the mistaken touch operation is determined, the misoperation of a user is avoided, and the use experience of the user is improved.

Example three:

different from the first embodiment, in the present embodiment, the manner of generating the false touch recognition result according to the unlocking state data recorded in the historical unlocking process and the device state data is specifically as follows: and training the obtained mistaken touch recognition model according to the unlocking state data recorded in all historical unlocking processes, and importing the obtained equipment state data into the mistaken touch recognition model so as to output a mistaken touch recognition result.

Fig. 23 shows a flowchart of an implementation of a method for unlocking a fingerprint according to a third embodiment of the present application, which is detailed as follows:

in S231, if it is detected that the fingerprint identification area has a pressing operation in the screen-locked state, device state data and fingerprint information corresponding to the electronic device at the time of the pressing operation are obtained.

In S232, a fingerprint matching result of the fingerprint information and a standard fingerprint is obtained.

In S233, importing the device state data into a preset false touch recognition model to obtain a false touch recognition result; the false touch recognition model is obtained based on the unlocking state data training.

In this embodiment, the above false touch recognition model includes, but is not limited to: and the intelligent recognition model is obtained by model training of a Support Vector Machine (SVM), a decision tree, ensemble learning, a neural network and the like.

In a possible implementation manner, the electronic device may obtain the above false touch recognition model through a local training manner. If the false touch recognition model is obtained in a local training mode, unlocking state data needs to be obtained firstly. In this case, the electronic device may obtain the unlock state data in a local collection manner, for example, in a process that a user uses the electronic device, the device state data of the electronic device at the time of performing the unlock operation is recorded every time the user performs the unlock operation, so as to obtain the unlock state data. The electronic equipment can also acquire the obtained unlocking state data in a downloading mode from the cloud server, under the condition, the state data of the equipment at the moment of executing the unlocking operation is recorded by the electronic equipment and other equipment every time the unlocking operation is executed, and the state data are uploaded to the cloud server, namely the cloud server can store the unlocking state data of all the terminals, and the electronic equipment can be downloaded from the cloud server. Of course, the user may first download the original unlock state data from the cloud, and then acquire the unlock state data in a manner of collecting the unlock state data from the local use process.

In a possible implementation manner, the electronic device may further obtain the false touch recognition model in a cloud downloading manner. The training process can be executed at the cloud server, and the electronic equipment only needs to download the error touch recognition model from the cloud server. Under this condition, electronic equipment can upload the unblock state data that the collection obtained to the high in the clouds server in the use to through the above-mentioned mistake of high in the clouds server update adjustment recognition model that touches, the high in the clouds server can regularly release above-mentioned mistake and touch recognition model.

In a possible implementation manner, the electronic device may obtain the false touch recognition model in a manner of combining cloud downloading and local training. In this case, the cloud server may train the unlocking state data uploaded by each device to obtain an original model, and send the original model to the electronic device. The electronic equipment can acquire unlocking state data in the using process, and trains the original model based on the locally acquired unlocking state data to acquire the false touch recognition model.

In S234, if the fingerprint matching result is a successful match and the false touch identification result is a false touch operation, the screen locking state is maintained.

Further, as another embodiment of the present application, if the false touch recognition result includes an unlocking probability, S234 specifically includes:

Further, as another embodiment of the present application, after S2351, the method further includes:

in S2352, a second touch operation initiated by the user on the electronic device is monitored, and the valid identifier corresponding to the unlock state data is configured based on the second touch operation.

Note that S2343 to S2345 are used to determine the unlocking intention of the user; and step S2352 is also for determining the user' S unlocking intention.

Further, as another embodiment of the present application, after S246, the method further includes:

in S2461, the unlock state data corresponding to the unlock operation is generated, and the unlock state data is used to determine a false touch recognition result.

In the embodiment of the application, when a user presses a fingerprint identification area, the electronic device acquires fingerprint information and also acquires device state data corresponding to the pressing operation moment, and when the fingerprint information is detected to be matched with a standard fingerprint, the device state data is compared with unlocking state data corresponding to a conventional unlocking process of the user, and a false touch identification result is obtained based on the comparison result, so that the identification of a false touch event is realized, and when the false touch operation is determined, a screen locking state is maintained, the possibility of false operation is reduced, and the use experience of the user is improved.

Compared with the first embodiment, the embodiment performs the fingerprint identification process, and performs the false touch identification operation after the fingerprint matching is successful. Since the response speed of the fingerprint recognition operation is faster and the calculation amount is smaller than that of the false touch recognition operation, the unlock state can be directly maintained when the fingerprint matching fails without performing the false touch recognition operation with a large calculation amount or waiting for the result of the false touch recognition operation, thereby reducing the unnecessary calculation amount.

Note that S2563 to S2565 are for determining the unlocking intention of the user; and step S2572 is also for determining the user' S unlocking intention. I.e. the two embodiments described above need to achieve similar technical effects. Therefore, if S256 is implemented by using the methods of S2563 to S2565 in the second embodiment, S2572 may not be included after S257; if S2572 is included after S257 in the second embodiment, S256 may be implemented without using S2563 to S2565.

Note that S2653 to S2655 are for determining the unlocking intention of the user; and step S2662 is also for determining the unlocking intention of the user. I.e. the two embodiments described above need to achieve similar technical effects. Therefore, if S265 is implemented by specifically employing the methods from S2653 to S2655 in the second embodiment, S2662 may not be included after S266; if S2662 is included after S266 in the second embodiment, S265 may be implemented without using S2653 to S2655.

Further, as another embodiment of the present application, after S2662, the method may further include:

at S2663, if the valid identifier of the unlock state data is the first bit value, performing a screen lock operation; and when the valid identifier is a first bit value, identifying the unlocking state data as invalid unlocking state data.

Example seven:

different from the first embodiment, in the seventh embodiment, the operation of generating the false touch recognition result according to the unlocking state data recorded in the historical unlocking process and the device state data is performed first, and after the fingerprint matching result is successful, the operation of obtaining the fingerprint matching result of the fingerprint information and the standard fingerprint is performed.

Fig. 27 shows a flowchart of an implementation of a method for unlocking a fingerprint according to a seventh embodiment of the present application, which is detailed as follows:

in S271, if it is detected that the fingerprint identification area has a pressing operation in the lock screen state, device state data and fingerprint information corresponding to the electronic device at the time of the pressing operation are obtained.

In S272, a false touch recognition result is generated according to the unlocking state data recorded in the historical unlocking process and the device state data.

In S273, if the false touch recognition result is a false touch operation, the screen lock state is maintained.

In S274, if the false touch recognition result is a non-false touch operation, a fingerprint matching result between the fingerprint information and a standard fingerprint is obtained.

In S275, if the fingerprint matching result is a matching failure, the lock screen state is maintained.

Further, as another embodiment of the present application, after S276, the method further includes:

in S2761, the unlock state data corresponding to the unlock operation is generated, and the unlock state data is used to determine a false touch recognition result.

Compared with the first embodiment, the embodiment performs the false touch recognition operation, and executes the fingerprint recognition process after determining that the false touch operation is not performed, and does not need to execute the fingerprint recognition and the false touch recognition for any pressing operation, thereby reducing unnecessary fingerprint recognition operation and reducing resource consumption in the unlocking process.

Example eight:

different from the seventh embodiment, in the present embodiment, the manner of generating the false touch recognition result according to the unlocking state data recorded in the historical unlocking process and the device state data is specifically as follows: and determining the unlocking probability of the intentional unlocking operation of the user at this time by counting the number of unlocking state data matched with the collected equipment state data at this time, and obtaining a false touch recognition result based on the unlocking probability.

Fig. 28 shows a flowchart of an implementation of a method for unlocking a fingerprint according to an eighth embodiment of the present application, which is detailed as follows:

in S281, if it is detected that the fingerprint identification area has a pressing operation in the lock screen state, device state data and fingerprint information corresponding to the electronic device at the time of the pressing operation are obtained.

In S282, the number of matches of the unlock state data with the device state data is counted from the unlock state data of all the historical unlock operations.

In S283, an unlocking probability is determined based on the matching number, and the false touch recognition result is obtained according to the unlocking probability and a preset unlocking determination threshold.

In S284, if the false touch recognition result is a false touch operation, the screen locking state is maintained.

Further, as another embodiment of the present application, S284 may specifically include:

in S2843, if the unlocking probability is smaller than the unlocking determination threshold, unlocking prompt information is output.

In S2844, if the first touch operation matched with the unlocking prompt information is not received within the preset effective response time, the screen locking state is maintained.

In S2845, if the first touch operation matched with the unlocking prompt information is received within the valid response time, a fingerprint matching result of the fingerprint information and a standard fingerprint is obtained.

In this embodiment, the electronic device receives the first touch operation matched with the unlocking prompt message within the effective response time, so that the fingerprint information can be matched with the standard fingerprint, and the electronic device can be directly unlocked after the fingerprint matching result which is successfully matched is obtained; on the contrary, if the fingerprint information is not matched with the standard fingerprint, a matching result of fingerprint matching failure can be obtained, and the electronic equipment is maintained in an unlocked state.

In a possible implementation manner, when the electronic device detects that the fingerprint matching fails, the electronic device may output fingerprint identification failure information on the touch screen to prompt the user to re-acquire the fingerprint information, and turn off the touch screen again after lighting for a preset time. Because the touch screen of the electronic device can be in the bright screen state when the first touch operation is collected, if the screen locking state of the electronic device is directly maintained, the user cannot determine that the touch operation is not matched with the unlocking prompt information or the fingerprint identification is wrong. Based on this, the electronic device can output fingerprint identification failure information to prompt the user to re-acquire fingerprint information.

Illustratively, fig. 29 shows a schematic diagram of fingerprint matching failure provided by an embodiment of the present application. Referring to fig. 29, the electronic device lights up the touch screen, and outputs unlocking prompt information, that is, "slide up to unlock" on the touch screen, and the user initiates a first touch operation of sliding up in the effective response time, at this time, the electronic device matches the fingerprint information collected in S281 with the standard fingerprint, and detects that the two are not matched, and therefore, outputs "fingerprint matching failure" information on the touch screen to prompt the user to collect the fingerprint information again.

As another embodiment of the application, if the electronic device detects that the first touch operation is matched with the unlocking prompt information and detects that the user initiates another pressing operation again in the fingerprint identification area within the preset screen lighting time, the fingerprint information is obtained again, the fingerprint information is matched with the standard fingerprint to obtain a fingerprint matching result, and the unlocking state data does not need to be collected again and the mistaken touch identification operation does not need to be carried out.

Further, as another embodiment of the present application, before S2843, the method further includes:

in S2841, a last historical pressing time corresponding to the historical pressing operation successfully matched with the standard fingerprint is acquired, and a pressing interval is determined based on the historical pressing time and the pressing operation time.

In S2842, the unlock determination threshold is configured based on the pressing interval.

In S285, if the false touch recognition result is a non-false touch operation, a fingerprint matching result between the fingerprint information and the standard fingerprint is obtained.

In S286, if the fingerprint matching result is a matching failure, maintaining the lock screen state

In S287, if the fingerprint matching result is a successful match, an unlocking operation is performed.

Further, as another embodiment of the present application, after S287, the method further includes:

in S2871, the unlock state data corresponding to the unlock operation is generated, and the unlock state data is used to determine a false touch recognition result.

Further, as another embodiment of the present application, after S2871, the method further includes:

in S2872, a second touch operation initiated by the user on the electronic device is monitored, and the valid identifier corresponding to the unlocking state data is configured based on the second touch operation.

It should be noted that S2843 to S2845 are used for determining the unlocking intention of the user; and step S2872 is also for determining the unlocking intention of the user. I.e. the two embodiments described above need to achieve similar technical effects. Therefore, if S284 in the second embodiment is implemented by using the methods of S2843 to S2845, S2872 may not be included after S286; if S2872 is included after S287 in the second embodiment, S284 may be implemented without using S2843 to S2845.

I.e. the two embodiments described above need to achieve similar technical effects. Therefore, if S303 is implemented by using the methods S3033 to S3035 in the second embodiment, S3062 may not be included after S306; if S3062 is included after S306 in the second embodiment, S303 may be implemented without S3033 to S3035.
