It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented in sequences other than those illustrated or otherwise described herein.
For the sake of understanding the embodiments of the present application, a specific description will be given by taking the management network system architecture shown in fig. 1 as an example.
In the management network system architecture shown in fig. 1, an intelligent security gateway management platform 101 and at least one intelligent security gateway 102 are specifically included. It should be noted that the management network system architecture may include one or more intelligent security gateways 102, where n is a positive integer in fig. 1 as an example. Fig. 1 is provided as an example only, and is not intended to limit the number of intelligent security gateway management platforms and the specific architecture of the network architecture. The functionality of the intelligent security gateway management platform 101 may be implemented by one or more servers. For example, the smart security gateway management platform 101 may be a server cluster made up of a plurality of servers. For example, the server cluster may include an extraction server, an encryption server, a monitoring server, a transmission server, and the like. Different servers may perform different functions, e.g. an encryption server is responsible for encrypting the portrait characteristic data. A library of people of interest may also be included in the intelligent security network management platform. In the present application, the attention person library stores at least portrait images of attention persons. For convenience of description, the intelligent security gateway management platform will be hereinafter simply referred to as a management platform.
The intelligent security gateway management platform 101 is configured to manage each intelligent security gateway 102, such as access management of the intelligent security gateway 102, and provide the personal characteristic data of the person of interest to each intelligent security gateway 102. The intelligent security gateway 102 is configured to collect a person image, and identify the collected person image in combination with the person image feature data of the person of interest provided by the intelligent security gateway management platform 101.
In order to solve the problem of low efficiency caused by comparing the acquired images with the images included in the attention personnel library, the application provides a method and a device for issuing the portrait characteristic data.
Referring to fig. 2A, a schematic flow chart of a method for issuing image feature data is provided. The method may be implemented by the management platform or by one or more servers in the management platform.
201A, the management platform obtains the person image of at least one person of interest that needs to be focused by the intelligent security gateway.
In one possible implementation, the management platform may obtain an image of the person of at least one person of interest that is of interest to the intelligent security gateway from a library of persons of interest.
The attention person library may include administrative region information to which the attention person belongs or administrative region or intelligent security gateway identification information to which the attention person needs to be focused, in addition to the portrait image of the attention person.
202A, the management platform extracts the portrait characteristic data of at least one person concerned, which is concerned by the intelligent security gateway, according to the at least one portrait image.
Illustratively, the management platform may include one or more servers, each of which may deploy a portrait engine. The management platform is also used for calling interfaces on one or more portrait engines for extracting portrait characteristic data to perform characteristic extraction on the portrait image of at least one person of interest to obtain portrait characteristic data of at least one person of interest.
Optionally, the extraction algorithm used by the management platform to extract the portrait characteristic data is obtained from the intelligent security gateway, and may also be preconfigured in the management platform. The extraction algorithm employed by each intelligent security gateway included in the network system of interest may be the same or different, and in one approach, the management platform is configured with the extraction algorithm employed by each intelligent security gateway when the network system is deployed. In another mode, in the process of establishing connection between the intelligent security gateway and the management platform, the intelligent security gateway can send an extraction algorithm adopted by the intelligent security gateway to the management platform.
Optionally, when the extraction algorithm of the intelligent security gateway is updated, the intelligent security gateway may notify the management platform of the updated extraction algorithm, and further, the management platform uses the updated extraction algorithm to extract the portrait characteristic data of the person of interest for the intelligent security gateway.
As one example, the portrait characteristic data may include characteristic data of five sense organs, face shape data, and the like. The portrait characteristic data may be text data in a text format.
203A, the management platform encrypts the portrait characteristic data of the at least one person of interest, and sends the encrypted portrait characteristic data of the at least one person of interest to the intelligent security gateway.
And after receiving the encrypted portrait characteristic data, the intelligent security gateway stores the data in a local database. And when the portrait characteristic data is applied subsequently, decrypting the portrait characteristic data by using the encryption card. The security of the portrait characteristic data is ensured, and the portrait characteristic data is prevented from being leaked. Further, the encryption card may be a removable storage device. For example, after receiving the encrypted portrait characteristic data, the intelligent security gateway inserts an encryption card to decrypt the encrypted portrait characteristic data.
As a possible implementation, in case the function of extracting the portrait characteristic data is performed by an extraction server in the server cluster, the extraction server may detect whether to connect with the encryption server before encrypting the portrait characteristic data. And when the connection is determined, sending the image characteristic data of the at least one person of interest to an encryption server for encryption.
In one possible implementation, both the process of encrypting the portrait characteristic data and the process of sending the portrait characteristic data may take the form of a thread pool.
In one mode, the processing module runs N first threads; acquiring an ith group of characteristic data included in the portrait characteristic data of the at least one person through an ith first thread in the N first threads, encrypting the ith group of characteristic data through the ith first thread running M second threads to obtain the encrypted ith group of characteristic data, and sending the encrypted ith group of characteristic data; the portrait characteristic data of at least one person comprises N groups of characteristic data, N is an integer greater than 1, and i is an integer smaller than or equal to N.
In another mode, the processing module runs N threads; the jth thread in the N threads encrypts the jth group of characteristic data included in the portrait characteristic data of the at least one person to obtain encrypted jth group of characteristic data, and sends the encrypted jth group of characteristic data; the portrait characteristic data of at least one person comprises N groups of characteristic data, N is an integer greater than 1, and j is an integer less than or equal to N.
Alternatively, the grouping of the ith group of feature data and the jth group of feature data may be performed according to different persons of interest, for example, the portrait feature data of one person of interest may be grouped into one group; the group may be made based on the data of the same part in the portrait characteristic data, for example, the characteristic data of the five sense organs of all the people may be divided into a group.
In one possible implementation, the management platform may have multiple encryption methods when encrypting the image feature data, for example, the encryption may be performed using an SDK (Software Development Kit ). After encrypting the portrait characteristic data of at least one person of interest, the management platform may package the encrypted portrait characteristic data of at least one person of interest, for example, may use an XML data packet form or may use other data packets form to package, which is not specifically limited in the embodiment of the present application.
In one possible implementation, each thread may have a counting function, and the data amounts of the data packets sent by different threads may be preconfigured, so that each thread may count the number of data packets sent, thereby determining whether the number of data packets of the sent portrait characteristic data is accurate.
In a possible implementation manner, when determining that the intelligent security gateway fails in the process of sending the encrypted portrait characteristic data of at least one person of interest to the intelligent security gateway, the management platform stores part of portrait characteristic data, which is not received by the intelligent security gateway, in the encrypted portrait characteristic data of at least one person; and when the intelligent security gateway fault recovery is detected, the stored partial portrait characteristic data are sent to the intelligent security gateway.
Optionally, when the encryption failure or the transmission failure occurs in the process of encrypting or transmitting the portrait characteristic data, the management platform may record the event of the encryption failure or the transmission failure through the system log. Optionally, the thread responsible for encryption can configure a timeout mechanism, and when the thread responsible for encryption detects the encryption timeout, an alarm page of the encryption timeout is popped up on the display screen; or when the transmission fails, the thread responsible for the transmission can pop up the warning page of the transmission failure on the display screen. After the management platform determines that the problem is solved, the portrait characteristic data can be continuously encrypted or sent in a breakpoint continuous transmission mode.
The breakpoint continuous transmission function refers to that after a thread for encrypting or transmitting portrait characteristic data fails, the intelligent security gateway management platform can find out a time point when a problem occurs by looking up a management platform system log, and after the problem is solved, encryption or transmission is continued based on the time point. Further, after the management platform finishes successful sending, a prompt page for successful sending can be displayed on a display screen. Similarly, when the management platform determines that the transmission fails, a prompt page of the transmission failure can be displayed on the display screen. And, the management platform may further record the event of successful or failed transmission in the system log.
In one possible implementation manner, the management platform detects a transmission rate of the encrypted portrait characteristic data of at least one person sent to the intelligent security gateway, and displays prompt information when an average value of the transmission rates in a set duration is smaller than a preset threshold value, where the prompt information is used for prompting that the transmission rate of the intelligent security gateway is low. For example, a warning page can be popped up on a display screen of the intelligent security gateway management platform to prompt that the transmission rate is low. Further, the manager can analyze the reason for the low transmission rate in time to resume transmission.
Referring to fig. 2B, a flowchart of another method for issuing image feature data according to the present application is shown.
201B, the management platform acquires the character image of at least one person of interest who needs to be focused by the intelligent security gateway.
See step 201A for a specific process.
202B, the management platform extracts the portrait characteristic data of at least one person concerned, which is concerned by the intelligent security gateway, according to the at least one portrait image.
See step 202A for a specific process.
203B, the management platform encrypts the image characteristic data of the at least one person of interest.
See step 203A for a specific encryption process.
204B, the management platform stores the encrypted portrait characteristic data of the at least one person of interest in a storage space and sends configuration information to the intelligent security gateway.
The configuration information is used for indicating the storage address of the encrypted portrait characteristic data of the at least one person of interest in the storage space, so that the intelligent security gateway can acquire the encrypted portrait characteristic data of the at least one person of interest from the storage space according to the configuration information.
In a possible implementation manner, the time for sending the configuration information to the intelligent security gateway by the management platform and the time sequence for storing the encrypted portrait characteristic data of at least one person of interest in the storage space are not specifically limited in the embodiment of the present application. For example, the management platform may send configuration information to the smart security gateway prior to extracting the portrait characteristic data; then, the management platform may store the encrypted portrait characteristic data of the at least one person of interest in a storage space indicated by the configuration information.
For another example, the management platform may send configuration information to the intelligent security gateway when the portrait characteristic data is stored in the storage space, for example, when the management platform stores the encrypted portrait characteristic data in the storage space for the first time, the management platform sends the configuration information to the intelligent security gateway.
Optionally, after receiving the configuration information, the intelligent security gateway may detect whether there is portrait feature data in the storage space indicated by the configuration information, and if so, perform an extraction operation.
The storage space may be regarded as a temporary database in the management platform, and the encrypted characteristic data may be stored in the storage space in time sequence. Alternatively, there may be multiple storage spaces, with different storage spaces having different storage addresses. Different storage spaces are used for storing different portrait characteristic data, or different storage addresses store the same portrait characteristic data.
In one possible implementation, the process of storing portrait characteristic data may take the form of a thread pool. For example, the processing module runs N first threads; storing the encrypted ith group of characteristic data into a storage space through the ith first thread in the N first threads; the portrait characteristic data of at least one person comprises N groups of characteristic data, N is an integer greater than 1, and i is an integer smaller than or equal to N.
In one possible implementation, each thread may have a counting function, and the data amounts of the data packets that are sent by different threads may be preconfigured, so that each thread may count the number of stored data packets, thereby determining whether the number of data packets of the stored portrait characteristic data is accurate.
Specifically, the intelligent security gateway extracts the portrait characteristic data of at least one person concerned after encryption in the storage space according to the storage address of the storage space indicated in the received configuration information.
In one possible implementation, after the intelligent security gateway successfully extracts the portrait feature data, the management platform may record an event in the system log that the portrait feature data was configured successfully.
In one possible implementation manner, after the intelligent security gateway extracts the portrait characteristic data of at least one person of interest, the management platform may configure the updated portrait characteristic data of the person of interest to the intelligent security gateway in the following manner, where the image of the person of interest in the person library of interest may be updated or the person of interest may be increased, and so on:
in one mode: the management platform determines that a first person image included in at least one person image to be focused by the intelligent security gateway is updated; the management platform extracts the portrait characteristic data of the first person according to the updated first portrait image; the management platform encrypts the portrait characteristic data of the first person, stores the encrypted portrait characteristic data of the first person into a storage space, and sends configuration information to the intelligent security gateway. And the intelligent security gateway acquires the encrypted portrait characteristic data of the first person from the storage space according to the configuration information.
In another mode: when the number of people needing to be concerned by the intelligent security gateway is increased, the management platform extracts the figure characteristic data of the newly added people according to the figure image of the newly added people; the management platform encrypts the portrait characteristic data of the newly-added attention person, stores the encrypted portrait characteristic data of the newly-added attention person into a storage space, and sends configuration information to the intelligent security gateway. And the intelligent security gateway acquires the encrypted figure characteristic data of the newly-added attention person from the storage space according to the configuration information.
As an example, the management network system may include n intelligent security gateways, and the management platform performs extraction and encryption issuing of the image feature data for each intelligent security gateway.
Illustratively, the kth smart security gateway is initially established to complete, e.g., one smart security gateway newly installed by a unit of a county. After the management platform is connected with the kth intelligent security gateway, the person image of the person concerned, which needs to be concerned by the kth intelligent security gateway, and the extraction algorithm of the kth intelligent security gateway can be obtained. And further extracting the portrait characteristic data aiming at an extraction algorithm of the kth intelligent security gateway, and encrypting and issuing the extracted portrait characteristic data to the kth intelligent security gateway. For convenience of description, the portrait characteristic data initially issued by the management platform is referred to as full-scale characteristic data. Optionally, after the configuration of the full feature data is successful, the management platform may record the event of successful configuration in the system log according to the method described in step 204B. Optionally, the management platform may also record the issue status of the full-scale feature data of each intelligent security gateway, such as issued, not issued, or being issued, and so on.
Aiming at the kth intelligent security gateway, after the management platform determines that the configuration of the full-quantity feature data of the kth intelligent security gateway is successful, the issuing state of the full-quantity feature data of the kth intelligent security gateway is changed from an undelivered state to an issued state.
In another possible manner, the person of interest k in the kth smart security gateway1 Person image update of (e.g. person of interest k)1 The character image is updated due to the hairstyle change. The management platform acquires the attention person k1 The updated character image is used for paying attention to the person k aiming at the extraction algorithm of the kth intelligent security gateway1 And encrypting and issuing the extracted portrait characteristic data to a kth intelligent security gateway. It should be noted that, on the kth intelligent security gateway, the updated attention person k1 The portrait characteristic data of (a) will be overlaid with the portrait characteristic data before update.
It should be noted that, in the embodiment of the present application, there may be overlapping among the attention personnel required to be paid attention to by multiple smart security gateways, for example, the attention personnel required to be paid attention to by the kth smart security gateway and the kth+1th smart security gateway each include the attention personnel k1 . Further, when the person image of a person of interest in the person-of-interest library is updated, for example, person of interest k1 The management platform needs to configure the updated attention person k to both the kth intelligent security gateway and the kth+1th intelligent security gateway1 Is of figure characteristic data of (a). Specifically, the k+1th intelligent security gateway is configured with the updated attention person k1 Means for human figure characteristic data and configuration of the updated attention person k to k intelligent security gateways1 The manner of the portrait characteristic data is similar and will not be described in detail here.
In another possible manner, the kth smart security gateway adds a person of interest k that needs attentionn . The management platform acquires the attention person kn Aiming at the person image of the kth intelligent security gateway, carrying out attention person k according to the extraction algorithm of the kth intelligent security gatewayn And encrypting and issuing the extracted portrait characteristic data to a kth intelligent security gateway.
For convenience of description, in the embodiment of the present application, the updated and newly added portrait characteristic data may be referred to as incremental characteristic data.
Referring to FIG. 3, a detailed description is provided in connection with a flow chart for configuring incremental feature data.
The following specifically describes an example in which the management platform is a server cluster composed of a plurality of servers. For example, an extraction server included in the server cluster is responsible for extracting incremental feature data, an encryption server is responsible for encrypting portrait feature data, a monitoring server is responsible for detecting a portrait image of a person of interest in a person-of-interest library, and so on.
301, a monitoring server in the management platform determines that the intelligent security gateway has been configured with the full amount of feature data.
The monitoring server of the management platform can perform periodic detection on the person images of the attention personnel in the attention personnel library or on the changes of the attention personnel required to be focused by the intelligent security gateway. For example, the detection period may be one day or 12 hours or one week, etc.
Here, the management platform is used for periodically detecting the person images of the attention person in the attention person library, and specifically, the increase of the attention person or the change of the person images of the attention person can be detected, so that the management platform generates the incremental characteristic data.
302, an extraction server in the management platform determines an intelligent security gateway needing to be configured with incremental feature data, acquires an extraction algorithm of the intelligent security gateway, and extracts the incremental feature data.
For a specific extraction process, see step 202B.
303, the extraction server in the management platform detects whether the connection with the encryption server is successful.
And if the connection is successful, the management platform sends the incremental characteristic data to the encryption server for encryption.
See step 203B for a specific encryption process.
304, a sending server in the management platform sends configuration information to the intelligent security gateway and stores the encrypted incremental feature data into the storage space.
See step 204B for specific storage procedures and transmit configuration information procedures.
And 305, the intelligent security gateway acquires the incremental characteristic data according to the configuration information.
See step 204B for a specific process.
306, it is determined whether the configuration was successful.
In one possible implementation manner, after the configuration is successful, a prompt page for the successful configuration appears on a display screen of the intelligent security gateway management platform; similarly, the configuration failure can also occur a prompt page of the configuration failure on a display screen of the intelligent security gateway management platform.
307, if the configuration is successful, the configuration is recorded in a system log of the management platform, and the state of the intelligent security gateway incremental feature data issuing is modified.
See step 204B for a specific process.
308, if the configuration fails, checking the system log of the management platform, finding out the failure reason, continuing the configuration through the breakpoint continuous transmission function after the problem is solved, and repeating the step 306.
309, the management platform determines whether there is a next smart security gateway that needs to be configured with incremental feature data.
If so, steps 302-309 are repeated.
In one possible implementation, after the incremental feature data is obtained by the smart security gateway, the data is saved in a local database. And when the portrait characteristic data is applied subsequently, decrypting the incremental characteristic data by using the encryption card. See step 203A for a specific decryption process.
