[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0034] At present, when user information is managed through a grid, the real-time performance of each user information in the grid is poor, which is not conducive to the further application of grid management. Based on this, a user information management method, an identity recognition method and an apparatus provided in an embodiment of the present application can effectively improve the real-time performance of user information in each grid area.

[0035] To facilitate understanding of this embodiment, a user information management method disclosed in the embodiment of the present application is first described in detail. Figure 1 A flowchart of a method for managing user information is shown, the method comprising the following steps:

[0036] Step S102: sampling and tracking the user's trajectory to obtain the user's location information.

[0037] It is understandable that users generally carry associated terminals such as mobile phones with them, and by receiving the positioning information sent by the associated terminal, the user's location information can be obtained. Specifically, the user's trajectory can be tracked through one or more positioning technologies such as BDS (BeiDou Navigation Satellite System, China's Beidou Satellite Navigation System), GPS (Global Positioning System, Global Positioning System), LBS (Location Based Service, Base Station Positioning), AGPS (Assisted Global Positioning System, Assisted Global Satellite Positioning System), GSM (Global System for Mobile communications, Global Mobile Communications System), IP (Internet Protocol, Internet Protocol) address positioning, WIFI (Wireless Fidelity, Mobile Hotspot) and gyroscope positioning, and then the user's location information is obtained, wherein the positioning accuracy of AGPS is low, while the positioning accuracy of GPS is high. Further, the associated terminal can also be a personal mobile device such as a laptop, a tablet computer, a smart watch, a smart bracelet, smart glasses, smart earplugs and a smart button-type device. It is understandable that when the user is sampled and tracked by receiving the location information sent by the associated terminal, the location information will carry the associated terminal ID (Identification) or the user's account information. At the same time, carrying the associated terminal ID or account information is helpful for quickly finding the corresponding user information.

[0038] Step S104: updating the current grid area where the user is located at the current sampling time according to the location information.

[0039] The grid is a further form of a mesh, which can directly express the position information and determine the grid area corresponding to the position coordinates. The grid area is obtained by pre-division. The embodiment of the present application further provides a method for dividing the grid area, which includes the following steps: first

[0040] (1) Establish a two-dimensional plane coordinate system.

[0041] Specifically, an X and Y two-dimensional coordinate axis is established based on the ground.

[0042] (2) Divide a region into several units.

[0043] The units of the X-axis and Y-axis are set to one kilometer, that is, every one kilometer is divided into one unit, and several units in the area can be obtained.

[0044] Taking an area of ​​2000 kilometers horizontally and 1500 kilometers vertically as an example, it needs to be divided into 2000*1500=3000000 grids.

[0045] (3) A unit is determined as a grid area, and the grid area is set in a grid server, and the grid is managed by the grid server.

[0046] In order to improve the utilization of the grid server, multiple grid areas can be set in one grid server. For example, take a region of 2000 kilometers horizontally and 1500 kilometers vertically as an example. If it is divided into 500 kilometers, it will be divided into 4 parts horizontally and 3 parts vertically, for a total of 12 small areas. Figure 2 A schematic diagram of a grid area is shown, where a region is divided into multiple units by the above method, and one unit is a grid area, namely, grid area 1, grid area 2, grid area 3, grid area 4, grid area 5, grid area 6, grid area 7, grid area 8, grid area 9, grid area 10, grid area 11 and grid area 12. In one embodiment, the above 12 grid areas can be deployed in the same or multiple grid servers. Preferably, the user density of each grid area is calculated, and the corresponding grid server is deployed for each grid area according to the user density.

[0047] Step S106, obtaining user information of the user corresponding to the account information.

[0048] In order to reduce the time used to obtain user information, user information can be obtained by retrieving the user's account information or associated terminal ID in each grid server. In another embodiment, the aforementioned location information includes the location data corresponding to the current sampling moment and the location data corresponding to the previous sampling moment of the current sampling moment. The grid area where the user was located at the previous sampling moment is determined by the location data corresponding to the previous sampling moment, so as to search the user information of the user in the grid server corresponding to the grid area. Among them, the user information can include the ID number of the user device, user category information, user coordinate type, user current coordinate data, the grid area where the user is located and the coordinate data update time. Specifically, the user coordinate type can be AGPS or GPS.

[0049] Step S108: updating the user information to the target grid server corresponding to the current grid area according to the mode information.

[0050] Among them, the authorization relationship table between the user and each business server can be established with the mode information, and the authorization relationship table is associated with the user information and saved to the target grid server. The business server can be a merchant server or an identity authentication server. Taking the business server as a merchant server as an example, because a merchant includes at least one sub-merchant, and a sub-merchant includes at least one merchant terminal, each merchant terminal of each merchant belongs to the merchant system of the merchant, wherein the merchant terminal can be configured to initiate a payment operation to the user. Specifically, the mode information can include a specified association mode and a full association mode. When the user's mode information is a specified association mode, when establishing the authorization relationship table, only the authorization relationship table between the user and the specified merchant server in the grid area where the user is located is established; when the user's mode information is a full association mode, an authorization relationship table between the user and each merchant server in the grid area where the user is located is established.

[0051] It is understandable that, because at least the sampling time (ie, the aforementioned coordinate data update time) has changed in the user information, the corresponding information should also be changed in a timely manner in the target grid server corresponding to the current grid area.

[0052] Specifically, when the grid area where the user is currently located is the same grid area as the grid area where the user was located at the previous sampling time, it is only necessary to update the coordinate data and the coordinate data update time in the target grid server; when the grid area where the user is currently located is different from the grid area where the user was located at the previous sampling time, but the grid area where the user is currently located and the grid area where the user was located at the previous sampling time belong to the same grid server, only the grid area where the user is located, the coordinate data and the coordinate data update time are changed in the grid server (that is, the target grid server); when the grid area where the user is currently located is different from the grid area where the user was located at the previous sampling time, and the grid area where the user is currently located and the grid area where the user was located at the previous sampling time do not belong to the same grid server, the user information in the grid server corresponding to the grid area where the user was located at the previous sampling time is migrated to the target grid server, and the grid area where the user is located, the coordinate data and the coordinate data update time are updated. In another implementation, if the location data at the previous sampling time is (0, 0), the user is a new user, and the user information of the user can be directly updated to the target grid server.

[0053] The user information management method provided in the embodiment of the present application obtains the user's location information by sampling and tracking the user's trajectory, thereby determining the current grid area where the user is located, and then obtains the user's user information, and updates the user information to the grid server corresponding to the current grid area according to the mode information in the user information. The present application samples and tracks the user's location information, timely updates the grid area where the user is located, and timely updates the user information in the grid server corresponding to the grid area, thereby improving the real-time performance of grid management.

[0054] To facilitate understanding of the above embodiment, the embodiment of the present application further provides a step of updating user information to a target grid server corresponding to the current grid area according to the mode information, the method comprising:

[0055] (1) In the target grid server corresponding to the current grid area, obtain the business information within the current grid area.

[0056] It is understandable that, because when identity recognition is completed based on grid management, identity recognition can only be completed when the user is within a certain range (usually within 2 meters) from the service terminal, it is preferred to obtain various service information within the grid area where the user is located.

[0057] (2) Establish an authorization relationship table based on the model information and business information.

[0058] The authorization relationship table includes the correspondence between account information and business information. When the user's mode information is the specified association mode, when establishing the authorization relationship table, only the authorization relationship table between the user and the specified merchant server in the grid area is established; when the user's mode information is the full association mode, the authorization relationship table between the user and each merchant server in the grid area is established.

[0059] (3) The authorization relationship table is associated with the user information and updated to the target grid server.

[0060] Specifically, first determine whether the grid area at the previous sampling moment is the same as the current grid area. If so, update the current sampling time in the authorization relationship table and user information in the target grid server; if not, determine whether the grid server corresponding to the grid area at the previous sampling moment is the same as the target grid server. If the grid server corresponding to the grid area at the previous sampling moment is the same as the target grid server, update the current sampling time and current grid area information in the authorization relationship table and user information in the target grid server; if the grid server corresponding to the grid area at the previous sampling moment is not the same as the target grid server, migrate the authorization relationship table and user information from the grid server corresponding to the grid area at the previous sampling moment to the target server. By comparing whether the grid areas where the users are located are the same and determining whether the corresponding grid servers are the same, the number of data updates can be reduced, thereby reducing the load pressure on the grid server.

[0061] Furthermore, when it is necessary to migrate the user information and the authorization relationship table, it is necessary to establish a corresponding user object in the target grid server, so as to associate the authorization relationship table with the user information and save it in the user object. In addition, in order to further improve the real-time performance of the user information stored in the grid server, the user information of the user can be deleted in the grid server corresponding to the grid area at the previous sampling time, so that the user information stored in the grid server is the user in the grid area at the current moment. In addition, deleting the user information that is not in the grid area in the grid server can also improve the storage space utilization rate in the grid server.

[0062] The embodiment of the present application can also provide timeout management. Specifically, it determines whether the user's location information is received within a preset time period. If not, the user information corresponding to the user is deleted in the designated grid server. That is, when the update time of the coordinate data in the user information exceeds a certain time, the user is deleted from the current grid.

[0063] In order to realize the intelligent management of the grid server, the sub-grid area can be further divided according to the user density of each grid area. For example, it is determined whether the user density of the current grid area is greater than the first preset threshold. If the user density is greater than the first preset threshold, a first positioning request is generated based on the user density, and the first positioning request is sent to the user's associated terminal, so that the associated terminal determines the target sub-grid area where the user is located based on the first positioning data returned by the first positioning request, and then determines the target sub-grid area where the user is located according to the first positioning data. Among them, the first positioning request requires the user to provide accurate positioning information and increase the frequency of updating the location information, so that the sub-grid area where the user is located can be determined, and the current grid area is dynamically divided into multiple sub-grid areas. Furthermore, based on the target sub-grid area where the user is located, the user information is updated in the target grid server corresponding to the target sub-grid area. Further, it can also be pre-divided into multiple grandchild grid areas.

[0064] In addition, it is also possible to determine whether the user density of the current sub-grid area is less than a second preset threshold value. When the user density is less than the second preset threshold value, a second positioning request is generated based on the user density, and the second positioning request is sent to the user's associated terminal, so that the associated terminal determines the target grid area where the user is located based on the second positioning data returned by the second positioning request, and then according to the second positioning data, updates the user information in the target grid server corresponding to the target grid area based on the target grid area where the user is located. Among them, the second positioning request does not require the user to provide accurate positioning information and reduces the frequency of updating the location information, thereby reducing the power consumption of the user's associated terminal.

[0065] For ease of understanding, Figure 3A schematic diagram of the division of a grid area using Beijing as an example is shown. When a user migrates from one grid area to another, the user density in the newly migrated grid area is calculated first. When the user density is too high, the sub-grid area is further divided based on the current grid area, such as Figure 4 A schematic diagram of the division of a sub-grid area is shown, wherein the sub-grid area can be in units of 100 meters; when the user density is too low and there are sub-grid areas, the sub-grid areas can be merged. Preferably, when the user density is too high, the user's trajectory is tracked by a higher-precision positioning method; when the user density is too low, there is no need to track the user's trajectory with a higher-precision positioning method.

[0066] Furthermore, with the continuous development of artificial intelligence technology, biometrics is being promoted and developed as a new technology. The current level of biotechnology, taking face recognition technology as an example, has reached more than 1 million face comparisons per second, and the error rate has reached one in ten million. Therefore, the current level of biotechnology has reached a new height. However, although the error rate has reached one in ten million, it is obviously still insufficient in the face of countries with super populations. In addition, biometric technologies such as faces will be affected by aspects such as shooting angle and lighting, which seriously affect the comparison results. Therefore, the embodiment of the present application also provides a method for identity recognition based on the above embodiment, see Figure 5 A flow chart of an identity recognition method is shown, the method comprising the following steps:

[0067] Step S502: using the user information management method provided in the above embodiment to update the user information in each grid server.

[0068] Step S504: when a service request sent by a service terminal is received, the grid area where the service terminal is located is determined according to the service request.

[0069] Among them, the business terminal can be a cash register, a POS (point of sale), a smart scanner, a handheld device, a smart TV, a mobile phone, a claw machine, a game console, an automatic payment machine, a self-service recharge machine, an intelligent facial payment device, a self-service terminal (e-government self-service terminal, e-banking self-service terminal, e-tax self-service terminal, hotel check-in self-service terminal, ATM (Automatic Teller Machine, automatic teller machine), a queuing machine, a number-taking machine, a self-service single machine, a self-service invoice machine, a self-service ticket collection machine and a self-service settlement machine, etc.), a shared device, an intelligent robot, an intelligent car, a drone, an identity authentication machine, a member and VIP identification device, an intelligent access control, an intelligent video intercom device and an intelligent gate and other devices. In addition, the business terminal can locate the position of the business terminal through one or more positioning technologies such as BDS, GPS, LBS, AGPS, GSM, IP address positioning, WIFI and gyroscope positioning to obtain the location information of the business terminal. Specifically, when the business terminal performs identity recognition, it will notify the target object to cooperate in completing the biometric information collection, so that the business terminal can determine the grid area where the business terminal is located based on the target object's living biometric information and the location information of the business terminal when receiving a business request sent by the business terminal according to the location information in the business request.

[0070] The biometric information may be one or more of the biometric features of face, iris, sclera, eye pattern, palm vein, palm print, ear print, finger vein and voice print.

[0071] Furthermore, the live biological feature information of the target object may be live human face information.

[0072] Step S506: in the grid server corresponding to the grid area where the service terminal is located, user information of each authorized user in the grid area where the service terminal is located is obtained according to the authorization relationship table.

[0073] It is understandable that, because the target object should be near the service terminal when handling the corresponding service, the user information of each user is searched preferentially in the grid area where the service terminal is located.

[0074] Step S508: searching for biometric information corresponding to each user information.

[0075] The corresponding pre-stored biometric information of each user is queried through the user information.

[0076] Preferably, in order to reduce the amount of data exchange, the grid server only stores the user information of the user, but not the user's biometric information, so as to improve the overall efficiency and stability. In addition, because the grid server is not configured to perform identity recognition based on biometric information, the response speed of the grid server can also be accelerated, further improving the stability of the grid server.

[0077] Step S510: performing biometric matching based on the target object's living biometric information and the biometric information corresponding to each user information to obtain a biometric matching result.

[0078] Preferably, before performing biometric matching, liveness determination is performed first to determine whether the liveness biometric information of the target object is directly derived from a live body, so as to prevent others from impersonating the biometric information of the target object through means such as photographs.

[0079] Step S512, completing identity recognition based on the biometric matching result.

[0080] For ease of understanding, the present application embodiment also provides a method for completing identity recognition based on biometric matching results, the method comprising the following steps:

[0081] (1) Determine whether the biometric matching result is a successful match.

[0082] (2) If yes, determine whether the successfully matched user is unique.

[0083] It is understandable that there may be users with similar biometric information to the target object, so it is determined whether the successfully matched user is unique.

[0084] (3) When the successfully matched user is unique, the successfully matched user is determined as the target object to complete identity recognition.

[0085] (4) When the successfully matched user is not unique, an identity confirmation request is sent to the associated terminal of each successfully matched user.

[0086] When the successfully matched user is not unique, an identity confirmation request is sent to the associated terminal of each successfully matched user, so that the target object returns identity confirmation information based on the identity confirmation request.

[0087] (5) When receiving the identity confirmation information sent by the associated terminals of each successfully matched user in response to the identity confirmation request, the identity confirmation information sent by each associated terminal is judged to obtain a judgment result.

[0088] (6) Complete identity recognition based on the judgment results.

[0089] After obtaining the user information of each user in the grid area where the business terminal is located, the user information and business request are sent to the payment system, so that the payment system searches for the corresponding biometric information based on the user information, and then completes the identity recognition and determines the identity information of the target object, thereby completing the payment operation. Specifically, the target object's live biometric information is matched with the biometric information of each user to determine the user information of the target object, and then complete the identity recognition. In addition, if the identity recognition does not match the user information corresponding to the target object, the user information of each grid area adjacent to the grid area where the business terminal is located can be obtained. Furthermore, the payment system can forward the live biometric information of the target object to the face recognition server, and identify the identity information of the target object through the specially designed face recognition server, thereby improving the efficiency of the payment system in performing payment operations.

[0090] by Figure 2 Taking the schematic diagram of a grid area as an example, when a service request sent by a service terminal is received, it is determined that the service terminal is in the grid area 12, and the user information currently in the grid area 12 is searched in the grid server corresponding to the grid area 12. After obtaining the user information of each user in the grid area 12, since the service request carries the live biometric information of the target object, after finding the biometric information corresponding to each user through each user information, biometric matching can be performed, and then identity recognition is completed, and the current user information corresponding to the target object is determined, and the payment operation is completed based on the current user information. If the identity recognition does not match the current user information corresponding to the target object, the information of each user in the grid area 11 or the grid area 8 can be obtained to reduce the problem of failure to complete the payment operation due to positioning error.

[0091] The method for identity recognition provided in the embodiment of the present application updates the user information in the grid server through the aforementioned user information management method and device, and determines the grid area where the business terminal is located based on the location information of the business terminal carried in the business request when receiving a business request, and then searches the grid server corresponding to the grid area where the business terminal is located according to the authorization relationship table for the user information of each authorized user in the grid area, obtains the biometric information corresponding to each user information, performs biometric matching on the live biometric information of the target object with the biometric information of each authorized user, and completes biometric identification based on the matching result. By obtaining user information in the corresponding grid area, the embodiment of the present application effectively reduces the amount of user information obtained, improves the speed and accuracy of biometric identification, and thus shortens the time used for identity identification, achieving the purpose of completing identity identification efficiently and accurately. In addition, narrowing the scope of obtaining user information to within a grid area can effectively alleviate the problem of poor recognition effect when biometric identification is applied in a country with a large population.

[0092] Further, see Figure 6 A structural schematic diagram of a system is shown, which includes a main server, and a dynamic grid server, a face recognition server and a payment server respectively connected to the main server, wherein the main server is configured to realize communication between the payment server, the dynamic grid server, the face recognition server and the business terminal and the user-associated terminal, the dynamic grid server is configured to confirm the grid area where the user and the business terminal are located, the face recognition server is configured to match the face information corresponding to the target object, and the payment server can be connected to other payment platforms and configured to complete the payment.

[0094] (1) Through grid management, the number of biometric features can be controlled within the grid and adjacent grids, which can reduce the number of biometric feature comparisons, thereby improving the biometric feature comparison search speed and reducing the investment in face recognition servers.

[0095] (2) The number of people in the grid can be dynamically adjusted according to the population distribution density.

[0096] (3) Raster map management is faster.

[0097] (4) Grid management does not require loading of biometric information, effectively reducing the amount of data exchange, thereby improving overall efficiency and stability;

[0098] (5) Grid management does not perform biometric matching operations, which speeds up the response of the grid server and makes the grid server more stable and reliable.
