具体实施方式 Detailed ways
以下结合附图和实施例详细说明本发明技术方案。The technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments.
本发明实施例提供的基于动态密码的触摸屏手机解锁方法可采用软件技术实现，流程图参见图7：The method for unlocking a mobile phone with a touch screen based on a dynamic password provided by the embodiment of the present invention can be implemented using software technology, and the flow chart is shown in Figure 7:
步骤1，判断是否要设置指纹样本，是则在触摸屏上提供指纹输入框，采集指纹输入框获取的指纹数据作为指纹样本，并将指纹样本存储至手机的数据库中，否则进入步骤2进行验证。Step 1. Determine whether to set a fingerprint sample. If yes, provide a fingerprint input box on the touch screen, collect the fingerprint data obtained in the fingerprint input box as a fingerprint sample, and store the fingerprint sample in the database of the mobile phone. Otherwise, go to step 2 for verification.
首次使用此功能时，需采集指纹样本。这其中包括指纹识别、指纹存储等过程以及系统核对指纹次数和欢迎语等功能设置。用户可以根据个人需求向数据库添加指纹数据。手机的数据库可采用现有技术实现，后续验证使用数据库保存的已有数据。可以在手机的中央处理器（CPU）中留出存储指纹数据的空间。When using this function for the first time, a fingerprint sample is required. This includes processes such as fingerprint identification and fingerprint storage, as well as functional settings such as the number of times the system checks fingerprints and welcome words. Users can add fingerprint data to the database according to their personal needs. The database of the mobile phone can be implemented by using the existing technology, and the subsequent verification uses the existing data stored in the database. Space can be set aside in the phone's central processing unit (CPU) to store fingerprint data.
步骤2，在触摸屏上提供指纹输入框，采集指纹输入框获取的指纹数据，对比指纹输入框获取的指纹数据和手机的数据库中存储的指纹样本，判断是否匹配， 是则进入手机的系统，否则进入步骤3。Step 2: Provide a fingerprint input box on the touch screen, collect the fingerprint data obtained by the fingerprint input box, compare the fingerprint data obtained by the fingerprint input box with the fingerprint samples stored in the database of the mobile phone, and judge whether they match. If yes, enter the system of the mobile phone, otherwise Go to step 3.
步骤3，判断验证次数是否达到预设的验证次数上限，是则进入步骤4，否则返回步骤2重新进行下一次验证。Step 3, judge whether the number of verification times reaches the preset upper limit of verification times, if yes, go to step 4, otherwise return to step 2 and perform the next verification again.
验证次数上限可由用户或手机厂商预先根据情况设置，实施例设置为3。The upper limit of verification times can be set in advance by the user or the mobile phone manufacturer according to the situation, and it is set to 3 in the embodiment.
步骤4，提示用户输入手机的PIN码，判断用户输入手机的PIN码是否正确，是则进入手机的系统，否则禁止进入手机的系统。Step 4, prompting the user to input the PIN code of the mobile phone, judging whether the PIN code entered by the user is correct, if so, entering the system of the mobile phone, otherwise forbidding to enter the system of the mobile phone.
步骤2、3、4实现验证过程，当用户输入的指纹与数据库中已存储的指纹数据相匹配时，便可成功登录手机系统；若两者无法匹配，则弹出提示窗口，要求用户重新输入指纹并进行核对，直至用户设置的验证次数上限为止。如果在规定的验证次数上限内无法成功解锁，则启用紧急通道——PIN码。用户可输入手机的PIN码进行手机解锁。Steps 2, 3, and 4 implement the verification process. When the fingerprint entered by the user matches the fingerprint data stored in the database, the mobile phone system can be successfully logged in; if the two cannot match, a prompt window will pop up asking the user to re-enter the fingerprint And check until the upper limit of verification times set by the user. If it cannot be successfully unlocked within the specified upper limit of verification times, the emergency channel - PIN code will be enabled. The user can enter the PIN code of the mobile phone to unlock the mobile phone.
经过对比分析，本发明建议手机所采用最优的触摸屏是电容式触摸屏。电容式触摸屏的构造主要是在玻璃屏幕上镀一层透明的薄膜体层，再在导体层外加上一块保护玻璃，双玻璃设计能彻底保护导体层及感应器 。电容式触摸屏在触摸屏四边均镀上狭长的电极，在导电体内形成一个低电压交流电场用户触摸屏幕时，由于人体电场，手指与导体层间会形成一个耦合电容，四边电极发出的电流会流向触点，而电流强弱与手指到电极的距离成正比，位于触摸屏幕后的控制器便会计算电流的比例及强弱，准确算出触摸点的位置。电容触摸屏的双玻璃不但能保护导体及感应器，更有效地防止外在环境因素对触摸屏造成影响，就算屏幕沾有污秽尘埃或油渍，电容式触摸屏依然能准确算出触摸位置。After comparative analysis, the present invention suggests that the optimal touch screen adopted by the mobile phone is a capacitive touch screen. The structure of the capacitive touch screen is mainly to coat a transparent film body layer on the glass screen, and then add a protective glass outside the conductor layer. The double glass design can completely protect the conductor layer and the sensor. Capacitive touch screens are plated with long and narrow electrodes on all four sides of the touch screen, forming a low-voltage AC electric field in the conductor. point, and the strength of the current is proportional to the distance from the finger to the electrode, the controller behind the touch screen will calculate the ratio and strength of the current, and accurately calculate the position of the touch point. The double glass of the capacitive touch screen can not only protect the conductors and sensors, but also effectively prevent external environmental factors from affecting the touch screen. Even if the screen is stained with dirty dust or oil stains, the capacitive touch screen can still accurately calculate the touch position.
用户对触摸屏的接触通过触摸传感技术采集，可采用现有技术。现有技术中触摸屏手机的屏幕由外到里依次为：触摸屏、触摸检测部件、显示器、触摸屏传感控制器。触摸传感控制器目前提供一些通用的性能选项和形态，如滑块和邻近传感器。触摸传感器技术的进步使传感器驱动型接口更易于实现，对终端用户更为直观和简单。大多数触摸传感控制器依据所检测到的电容变化来工作。当某种物体或某个人接近或触摸传感器的导电金属片时，手指与金属片之间的电容发生变化。导电物体(如手指)在传感器附近移动将改变电容传感器的电场线并使电容发生变化。控制电路可测出电容的变化。触摸传感器接口通常通过测量与传感器垫片相连的电路的阻抗来检测电容变化。触摸控制器周期性地测量传感器输入通道的阻抗并用这些值来导出一个内部基准，即校准阻抗。控制器以这个阻抗值为基础判定是否发生了触摸事件。The user's contact with the touch screen is collected through touch sensing technology, which can adopt the existing technology. The screen of the touch screen mobile phone in the prior art is sequentially arranged from the outside to the inside: a touch screen, a touch detection component, a display, and a touch screen sensing controller. Touch-sensing controllers currently offer some common performance options and modalities, such as sliders and proximity sensors. Advances in touch sensor technology have made sensor-driven interfaces easier to implement, more intuitive and simpler for the end user. Most touch-sensing controllers operate based on detected changes in capacitance. When an object or a person approaches or touches the conductive metal piece of the sensor, the capacitance between the finger and the metal piece changes. Moving a conductive object, such as a finger, near the sensor changes the electric field lines of the capacitive sensor and causes a change in capacitance. The control circuit can measure the change of capacitance. Touch sensor interfaces typically detect changes in capacitance by measuring the impedance of the circuit connected to the sensor pad. The touch controller periodically measures the impedance of the sensor input channels and uses these values to derive an internal reference, the calibration impedance. Based on this impedance value, the controller determines whether a touch event has occurred.
步骤1采集指纹样本和步骤2获取指纹数据需要进行指纹识别。具体指纹识别目前有两种现有技术：A、读取指纹图像，对初步读取到的人体指纹图像进行清晰处理；建立指纹的数字特征数据；利用模糊比较法，对输入指纹和已存指纹进行对比。B、取像和取像设备，光学设备（历史久远），利用光的全反射原理；优点：体积小（3*1*1英寸）；纤维光、微型三棱镜矩阵，硅晶体传感器（最近），例如：电容传感器、温度感应传感器、超声波扫描（指纹取像技术中非常好的一类，建议使用）。通过对两种方式比较，前一种价格低、体积小、识别率高。Fingerprint identification is required for collecting fingerprint samples in step 1 and obtaining fingerprint data in step 2. There are currently two existing technologies for specific fingerprint identification: A. Read the fingerprint image, and clearly process the initially read human fingerprint image; establish digital feature data of the fingerprint; use the fuzzy comparison method to compare the input fingerprint and the stored fingerprint comparing. B. Imaging and imaging equipment, optical equipment (long history), using the principle of total reflection of light; advantages: small size (3*1*1 inches); fiber optics, micro-prism matrix, silicon crystal sensor (recently), For example: capacitive sensor, temperature sensing sensor, ultrasonic scanning (a very good type of fingerprint imaging technology, it is recommended to use). By comparing the two methods, the former one is low in price, small in size and high in recognition rate.
为改进指纹识别效果，可以进行图像增强：当手指不干净或者有伤疤、干燥、湿润时，不能获得清晰的图像。为了克服这种现象，可以设计一个适合、匹配的滤镜和恰当的阀值。可参考第三代生物射频传感器：第三代生物射频指纹识别技术，射频传感器技术是通过传感器本身发射出微量射频信号，穿透手指的表皮层去控测里层的纹路，来获得最佳的指纹图像。因此对干手指，汉手指等困难手指通过可高达99%，防伪指纹能力强，指纹敏感器的识别原理只对人的真皮皮肤有反应，从根本上杜绝了人造指纹的问题，宽温区：适合特别寒冷或特别酷热的地区。因为射频传感器产生高质量的图像，因此射频技术是最可靠，最有力的解决方案。除此之外，高质量图像还允许减小传感器，无需牺牲认证的可靠性，从而降低成本并使得射频传感器思想的应用到可移动和大小不受拘束的任何领域中。In order to improve the fingerprint recognition effect, image enhancement can be carried out: when the finger is not clean or has scars, dry or wet, a clear image cannot be obtained. In order to overcome this phenomenon, a suitable and matching filter and an appropriate threshold can be designed. Refer to the third-generation bio-RF sensor: the third-generation bio-RF fingerprint recognition technology. The RF sensor technology emits a small amount of RF signal through the sensor itself, penetrating the skin layer of the finger to control and measure the texture of the inner layer to obtain the best fingerprint image. Therefore, it can pass up to 99% of dry fingers, Han fingers and other difficult fingers. It has strong anti-counterfeiting fingerprint capabilities. The recognition principle of the fingerprint sensor only responds to human dermis, which fundamentally eliminates the problem of artificial fingerprints. Wide temperature range: Ideal for extremely cold or extremely hot regions. Because RF sensors produce high-quality images, RF technology is the most reliable and robust solution. In addition to this, the high image quality allows the sensor to be reduced without sacrificing the reliability of the authentication, thereby reducing the cost and enabling the application of the RF sensor idea to any field where it is mobile and size-independent.
本发明进一步提出，可以采集一个以上手指的指纹样本并存储至手机的数据库中；当进入步骤2进行验证时，在触摸屏上提供相应数目的钥匙图标，当用户点击某一钥匙图标时，在触摸屏上提供指纹输入框，对比指纹输入框获取的指纹数据和手机的数据库中存储的相应指纹样本。The present invention further proposes that the fingerprint samples of more than one finger can be collected and stored in the database of the mobile phone; when entering step 2 for verification, a corresponding number of key icons will be provided on the touch screen; A fingerprint input box is provided on the screen, and the fingerprint data acquired in the fingerprint input box is compared with the corresponding fingerprint samples stored in the database of the mobile phone.
为便于实施参考，提供实施例的具体实现流程说明如下：For the convenience of implementation reference, the specific implementation process description of the embodiment is provided as follows:
(1)当用户首次使用此功能时，需进行指纹数据采集，经过信息处理后，将该数据存至数据库中。此步骤是对指纹数据的采集、图像与处理的综合应用，包括以下子步骤。(1) When the user uses this function for the first time, fingerprint data collection is required, and after information processing, the data is stored in the database. This step is a comprehensive application of fingerprint data collection, image and processing, including the following sub-steps.
(1.1) 如图8所示，实施例所用手机的屏幕由外到里依次为：触摸屏101、触摸检测部件102、显示器103、触摸屏传感控制器104和指纹采集器105。指纹采集器可参考现有技术实现，例如晶体传感器等。所得指纹存储至手机的数据库106中。(1.1) As shown in Figure 8, the screen of the mobile phone used in the embodiment is sequentially from outside to inside:
在用户的手指触摸安装在显示器前端的触摸屏之后，系统根据手指在指定位置的指纹录入进行数据分析。触摸检测部件位于显示屏幕前，主要作用是检测用户触摸位置，而触摸屏传感控制器的主要作用是从触摸检测装置上接受触摸信息，并将其转换成出点坐标，再传送给手机的CPU；同时指纹采集器采集指纹的图像，所得采集图像输入CPU。这时坐标数值将会与指纹采集器的坐标数值（和预设的指纹输入框位置一致）进行比较，若输入的坐标在指纹处理器的坐标之内，则CPU开始进行指纹图像的处理。After the user's finger touches the touch screen installed on the front of the display, the system performs data analysis based on the fingerprint entry of the finger at the designated position. The touch detection component is located in front of the display screen, and its main function is to detect the user's touch position, while the main function of the touch screen sensor controller is to receive touch information from the touch detection device, convert it into the coordinates of the exit point, and then send it to the CPU of the mobile phone ; At the same time, the fingerprint collector collects the image of the fingerprint, and the acquired image is input to the CPU. At this time, the coordinate value will be compared with the coordinate value of the fingerprint collector (consistent with the position of the preset fingerprint input box). If the input coordinate is within the coordinate of the fingerprint processor, the CPU will start processing the fingerprint image.
(1.2)指纹图像处理主要包括图像采集、图像预处理、细节点提取及指纹匹配。其中在(1.1)通过指纹采集器已完成对图像采集，指纹采集器采集的图像输入cpu，接下来需要进行图像预处理。预处理的目的是去除图像中的噪声，把它变成一幅清晰的点线图，以便提取正确的指纹特征，从而达到正确匹配。预处理过程主要包括指纹规格化、平滑滤波处理、方向增强处理、二值化、细化等，可采用现有技术，本发明不予赘述。(1.2) Fingerprint image processing mainly includes image acquisition, image preprocessing, minutiae extraction and fingerprint matching. Wherein (1.1) the image acquisition has been completed by the fingerprint collector, and the image collected by the fingerprint collector is input into the CPU, and image preprocessing is required next. The purpose of preprocessing is to remove the noise in the image and turn it into a clear point-line map in order to extract the correct fingerprint features and achieve correct matching. The preprocessing process mainly includes fingerprint normalization, smoothing filter processing, direction enhancement processing, binarization, thinning, etc., and existing technologies can be used, which will not be described in detail in the present invention.
(1.3)在步骤(1.2)的基础上提取指纹特征信息，得到指纹特征模板，即可作为指纹样本存储至指纹数据库中的有效数据。(1.3) On the basis of step (1.2), the fingerprint feature information is extracted to obtain a fingerprint feature template, which can be used as valid data stored in the fingerprint database as a fingerprint sample.
以上指纹图像的处理过程可采用软件编程技术由cpu执行实现，也可以将图像预处理过程模块化设计为采用图像转换器实现，生成输入指纹特征模板可模块化设计为采用指纹模板处理器实现。指纹采集器输出图像到图像转换器，图像转换器输出到指纹模板处理器，然后存储到数据库。The processing process of the above fingerprint image can be implemented by the cpu using software programming technology, and the image preprocessing process can be modularly designed to be implemented by using an image converter, and the generated input fingerprint feature template can be modularly designed to be implemented by using a fingerprint template processor. The output image of the fingerprint collector is sent to the image converter, and the output of the image converter is sent to the fingerprint template processor, and then stored in the database.
为了提高效率，具体实施时，用户输入指纹时可以先通过触摸屏进行指纹触点的定位及判断；当采集指纹输入框获取的指纹数据时，先根据触摸屏传感控制器采集后输入手机的中央处理部件的坐标信息，判断用户输入的坐标是否在指纹输入框内，是则对采集图像进行图像预处理并提取指纹特征信息，否则提示重新输入。可以通过触摸检测部件和触摸屏传感控制器的坐标数值与指纹处理器的坐标数值进行比较，若所输入的内容的坐标在指纹处理器的坐标之内，则CPU开始进行指纹图像的处理。所输入的指纹在规定范围内时，采用指纹处理器处理得到指纹特征模板，并将其存入数据库中。In order to improve efficiency, when the user inputs the fingerprint, the user can first locate and judge the fingerprint contact through the touch screen; The coordinate information of the component is used to determine whether the coordinates input by the user are in the fingerprint input box, and if so, perform image preprocessing on the collected image and extract the fingerprint feature information, otherwise prompt to re-enter. The coordinate value of the touch detection component and the touch screen sensor controller can be compared with the coordinate value of the fingerprint processor. If the coordinates of the input content are within the coordinates of the fingerprint processor, the CPU starts to process the fingerprint image. When the input fingerprint is within the specified range, the fingerprint processor is used to process the fingerprint feature template and store it in the database.
步骤2中，先判断用户输入的坐标是否在指纹输入框内，是则对比指纹输入框获取的指纹数据和手机的数据库中存储的指纹样本，否则提示重新输入。In step 2, first determine whether the coordinates input by the user are in the fingerprint input box, and if so, compare the fingerprint data acquired in the fingerprint input box with the fingerprint samples stored in the database of the mobile phone, otherwise prompt to re-enter.
(2) 用户每次使用手机，验证使用过程如下：(2) Every time the user uses the mobile phone, the verification process is as follows:
用户每次使用手机，点亮屏幕时，会出现一扇已有一把锁的中国式大门（大门旁边会有一把或并列摆有几把钥匙（根据数据库里的指纹个数决定。即指纹库有一个指纹，桌面上有一把钥匙），如图1。Every time the user uses the mobile phone, when the screen is turned on, a Chinese-style door with a lock will appear (there will be one or several keys placed side by side next to the door (determined according to the number of fingerprints in the database. That is, the fingerprint database has A fingerprint, a key on the table), as shown in Figure 1.
当用户点击钥匙图标时，屏幕会显示如图2所示的空白区域作为指纹输入区，弹出“开启指令”提示用户输入指纹。对输入指纹的采集、图像与处理与（1）实现方式一致，具体匹配可采用现有技术。When the user clicks the key icon, the screen will display a blank area as shown in Figure 2 as the fingerprint input area, and an "open command" will pop up to prompt the user to input the fingerprint. The collection, image and processing of the input fingerprints are consistent with (1), and the specific matching can use the existing technology.
当用户的指纹信息匹配成功时，画面中门上的锁会自动打开，并且出现欢迎语（用户可个性化设置，例如“Welcome！”）开门后即可看到手机桌面信息，如图3。When the user's fingerprint information is successfully matched, the lock on the door in the screen will be automatically unlocked, and a welcome message will appear (users can customize it, such as "Welcome!"). After opening the door, you can see the desktop information of the mobile phone, as shown in Figure 3.
若用户的指纹匹配不成功，则会弹出提示信息“请重新输入指令”要求用户在指纹区重新输入。同时，门锁会增加一把锁（门锁增加的个数由机主设定的验证次数有关，例如，机主设定验证次数为三，则门锁最大值有3把），如图4出现了两把锁。If the user's fingerprint matching is unsuccessful, a prompt message "Please re-enter the command" will pop up to ask the user to re-enter in the fingerprint area. At the same time, the door lock will add a lock (the number of door locks added is related to the number of verifications set by the owner, for example, if the number of verifications set by the owner is three, the maximum number of door locks is 3), as shown in Figure 4 Two locks appeared.
若三次验证权限已用完，屏幕会显示“抱歉，开启不成功，您无法进入！”，如图5，出现了三把锁。If the three verification permissions have been exhausted, the screen will display "Sorry, the opening was unsuccessful, you cannot enter!", as shown in Figure 5, three locks appear.
为了确保因识别不清晰等因素干扰到本机机主无法正常使用手机，在如图5所示情况发生时，桌面的右下角会有“紧急通道”字样。当用户点击时，屏幕会弹出“请输入本机PIN码”的提示，如图6。这时用户只要输入正确的PIN码即可进入到自己的手机系统中。In order to ensure that the owner of the mobile phone cannot use the mobile phone normally due to factors such as unclear identification, when the situation shown in Figure 5 occurs, the word "emergency channel" will be displayed in the lower right corner of the desktop. When the user clicks, the screen will pop up a prompt "Please enter the local PIN code", as shown in Figure 6. At this time, the user only needs to input the correct PIN code to enter into the mobile phone system of oneself.
若用户最终无法解锁手机或手机丢失时，用户可到该手机品牌的官网上进行挂失。在输入自己的身份证等有效证件后，便可通过云服务读取下载自己的重要信息。用户在使用时需将自己的信息上传到云服务器的前提下，才可下载读取信息。这样既可以保护行货手机的版权，与水货手机服务相区别，又可以为用户提供方便安全的服务。If the user cannot finally unlock the mobile phone or loses the mobile phone, the user can report the loss on the official website of the mobile phone brand. After entering your own ID card and other valid documents, you can read and download your important information through cloud services. Users can only download and read information under the premise of uploading their own information to the cloud server when using it. In this way, the copyright of licensed mobile phones can be protected, which is different from parallel mobile phone services, and convenient and safe services can be provided for users.
验证过程中的获取指纹数据具体实现与（1）中采集指纹样本的具体实现一致。The specific implementation of fingerprint data acquisition in the verification process is consistent with the specific implementation of fingerprint sample collection in (1).
