Personal identification verification refers to a method of verifying the identity of a living body, especially between a living body's face and personal identification data. In traditional technology, the verification of personal identification is generally done by encapsulating an interface through a back-end service.

Save the base map if passed. Specifically, it is divided into the following two situations:

1) If it is a person who is not on the document to verify the certificate, because the base map of the person on the document and the person on the document are easily judged to be inconsistent, it is easy to compare the base map every time the interface encapsulated by the back-end service is called. Pass, it will call the public security interface that needs to spend money;

2) When the corresponding person on the certificate is verified in real time, if the corresponding person on the certificate fails to compare with the base map, it will call the public security interface that needs to spend money.

For electronic devices such as electronic devices, the application scenarios of the above-mentioned personal identification verification method are only used to illustrate the technical solutions of this application, and are not used to limit the technical solutions of this application. The above-mentioned connection relationship may also have other forms.

Please refer to FIG. 2. FIG. 2 is a first schematic flowchart of a method for verifying a person's certificate according to an embodiment of the application. The method for verifying the person's certificate is applied to the server in FIG. 1 to complete all or part of the functions of the method for verifying the person's certificate. As shown in Figure 2, the method includes the following steps S210-S240:

S210. Receive a face image and identity information, where the identity information includes an ID number.

Among them, the face image refers to a face image, and the identity information includes an ID number.

Specifically, the terminal can take a face image through a camera, and obtain the identity information input by the user through a keyboard or voice device, etc., and send the face image and identity information to the back-end server for verification of the identity through a wired or wireless network After receiving the face image and identity information, the server verifies the face image.

S220. Determine, according to the identity information, whether a first face base map corresponding to the identity information is stored, wherein the first face base map is a person whose score is greater than or equal to a first preset score threshold Face base map, the score of the first face base map is derived from the real-time comparison score returned by the third-party interface for verification of the first face base map, used to describe the first face The similarity between the base map and the face base map stored in the third-party interface.

Among them, the face base map refers to the basis for comparison in the process of verifying the personal evidence. The face map and the face base map are compared to determine whether the face map and the face base map are similar or consistent, and then to determine the personal evidence Verified user identity.

The first face base map is a face base map with a score greater than or equal to a first preset score threshold, and the first preset score threshold is proportional to the accuracy of the first face base map Relationship, the higher the first preset score threshold is set, the more similar the first face base map is to the face base map stored in the third-party public security interface, and the face map is similar to the first face base map The result of personal identification verification is closer to the result of human identification verification by calling the public security interface of a third party on the face map. Wherein, the score of the first face base map is derived from the comparison score returned in real time by the third-party interface for verification of the first face base map, and is used to describe the first face base map The degree of similarity with the face map stored in the third-party interface. Specifically, the score of the first face map is verified by the third-party public security interface on the face map corresponding to the first face map. The comparison score returned by the kernel in real time is the comparison score returned by the public security interface according to the internal algorithm when the first face base map is compared with the face base map in the third-party public security system interface. , Used to describe the similarity between the first face base map and the face base map stored in the third-party public security interface, and the first face base map is similar to the face base map stored in the third-party public security interface The similarity of is proportional to the comparison score. The higher the comparison score, the more similar the first face base map is to the face base map stored in the third-party public security interface. If the score value returned by the public security interface of the face map corresponding to the first face base map is greater than or equal to the first preset score threshold during the verification of the human face in real time, the server converts the face corresponding to the first face base map The picture is saved as the first face base picture. Further, the first preset score threshold may be set according to actual business requirements for the accuracy of the verification of the personal identification. If the actual business requires high accuracy of verification of the identification, the first preset threshold may be set The larger the setting, the larger the first preset score threshold, the higher the similarity between the first face base map and the face base map in the public security system interface, and the more accurate the result of the verification of the human ID, the first preset score threshold The lower the lower, the similarity between the first face base map and the face base map in the public security system interface will be reduced accordingly, and the result of the verification of the personal identification is relatively inaccurate. Generally, in order to ensure the reliability of the verification of the personal identification, the first preset score The value threshold should be set much higher than the bottom line of the public security system interface verification. It should be noted that during the verification process, the default face base map stored in the third-party public security interface is true and reliable, and the face base map stored in the third-party public security interface is used for verification. Benchmark. For example, taking the full score as 100 points, the first preset score threshold is set to 90 points, and the face base maps are classified according to the scores obtained from the public security interface of the face base maps, and the face maps are compared. The face map with a value greater than or equal to 90 points is divided into the first face base map, which may also be called a reliable base map.

Specifically, after the server receives the face image and identity information uploaded by the terminal, it judges based on the identity information whether the first face base map corresponding to the identity information is stored in the server’s local database, and if the identity information is stored in the server Corresponding to the first face base map, first compare the face map with the first face base map local to the server. If the first face base map corresponding to the identity information is not stored in the server, you can compare The face image is compared with the second face base image, or the third-party public security interface is called for the comparison of human identification verification, and the third-party public security interface is called. On the one hand, it will prolong the interface response time of human identification verification. On the other hand, the third-party public security interface is paid to call, and the call fee needs to be paid.

Further, there are two ways to determine whether the first face base map corresponding to the identity information is stored according to the identity information:

1) Check whether the first face base map corresponding to the identity information is found in the database of the server. Directly according to the identity information, go to the database of the server to find whether the first face base image of the face image exists. If the amount of data in the database is relatively large, the search time will be appropriately extended.

2) By means of preset logos or keywords. The server establishes a preset identifier for the identity information of the base map of the human face stored in the database, and performs real-time verification of the human identity. The preset identifier is first searched according to the identity information. If the preset identifier corresponding to the identity information can be found, the database is judged The first face base map corresponding to the identity information is stored, and if the preset identifier corresponding to the identity information cannot be found, it is determined that the first face base map corresponding to the identity information is not stored in the database. It is also possible to set keywords, for example, if the keyword is set to "TRUE", it is determined that the first face base map corresponding to the identity information is stored in the database, and the keyword is set to "FALSE" to determine that there is no The first face base map corresponding to the identity information is stored. Since the preset identifier or keyword is smaller than the amount of data in the database, the efficiency of judgment can be improved, thereby shortening the time for verification of the witness.

It should be noted that the face base map is generally derived from the face map uploaded by the terminal received by the server, that is, the server saves the face map whose score meets the requirements as a face base map to facilitate subsequent verification of the same identity information. . Under normal circumstances, in real-time verification of personal identification, if there is no face base map or the comparison between the face map and the face base map fails, the server will call the public security interface for verification. The personal information of the public security system is due to its authority. Sexuality is generally considered to be reliable. After the public security interface receives the call to verify the identity, it will compare the face map with the face map stored in the database of the public security system according to the identity information using the internal comparison of the public security system. The algorithm is compared, and the public security interface will return information such as the comparison result and the score of the comparison between the face image and the face base image in the public security system to the server, so that the server obtains the face image and the public security interface The comparison score of the face base map is used to determine the similarity between the face map and the face base map saved in the public security system, and then to determine the similarity between the face map and the human face. It should be noted that, In the process of verification, the default is to use the base map of the face stored in the public security system as the basis for comparison, that is, the base map of the face stored in the public security system is the closest to the real face of the living body.

S230: If the first face base map is stored, compare the face map with the first face base map to obtain a verification result of the verification.

Specifically, if the server determines that the first face base map corresponding to the identity information is stored, the face map is compared with the first face base map to obtain the comparison result, because the first person The face base map is very similar to the face base map of the public security interface, and it is more reliable as a personal certificate verification. The result of the personal certificate verification can be used as the final comparison result regardless of whether the personal certificate verification verification is passed. Since the score of the first face base map is higher, it indicates that the first face base map is more similar to the face base map corresponding to the identity information stored in the public security interface of the third party, because the identity stored in the public security interface is considered The face base map corresponding to the information is true and reliable. The more similar the first face base map and the face base map corresponding to the identity information stored in the public security interface are, the ratio of the face map to the first face base map can be considered The closer the result is to the comparison result of the face map and the face base map corresponding to the identity information in the public security interface, the more reliable the comparison result of the face map and the first face base map can be judged, and the comparison result obtained The more precise.

Further, in S240, if the first face base map is not stored, compare the face map with the second face base map, or call a third-party interface for verification.

Wherein, the second face base map is a face base map with a score greater than or equal to the second preset score threshold and less than the first preset score threshold. For example, taking the full score as 100 points, the face base map is classified according to the score obtained from the public security interface of the face base map, and the face base map with a face map score greater than or equal to 90 points is divided into the first A face base map, which divides the face base map whose score is less than 90 points and greater than or equal to 60 points into a second face base map, which can also be called a normal base map, where the normal base map is The public security interface passes the verification of the face image as a common base map, but according to the score, the face map is not so accurate. The bottom limit of the common base map is that the public security interface verifies the face map.

Specifically, if the first face base map is not available, the face map is compared with the second face base map to determine whether the verification of the face map passes. Since the reliability of the second face base map is not so high, if the comparison is passed, it indicates that the face map is similar to the face base map of the third-party public security interface and can be used as the final comparison result. No, considering the difference between the second face base map and the face base map of the public security interface, the third-party public security interface is further invoked to verify the face map, and finally a reliable personal identification is obtained through the public security interface Verify the results.

Alternatively, if the server does not store the first face base map corresponding to the identity information, the third-party interface is invoked to perform the identification verification to obtain the comparison result of the identification verification from the third-party interface. If there is no face base map or the first face base map, you can call the public security interface of a third party to verify the personal identification through the public security interface, obtain the verification result from the public security interface, and obtain the personal identification verification from the public security interface. The results include information such as the comparison score between the face map and the face base map in the public security interface during the verification of the personal certificate or the failure of the verification of the personal certificate, and the internal comparison of the personal certificate in the public security interface in real time. Algorithm, due to the authority of the public security interface, it is generally believed that the data and comparison results of the public security interface are accurate and reliable.

The server displays the comparison result of the obtained ID verification or the ID verification, or returns the comparison result of the ID verification obtained in the above steps to the terminal to prompt the user through the terminal.

According to the method for verification of person identification provided by the embodiment of this application, when the interface for verification of the person identification is optimized, if a face image and identity information for verification of the person's certificate are received, it is judged according to the identity information whether there is a second corresponding to the said identity information. A face base map, where the first face base map is a face base map with a score greater than or equal to a first preset score threshold, and the score of the first face base map comes from a third-party interface pair The comparison score value returned by the first face base map for verification in real time is used to describe the similarity between the first face base map and the face base map stored in the third-party interface, if stored The first face base map, the face map is compared with the first face base map to obtain the comparison result of the witness verification. In the embodiment of this application, the face map in the verification verification is compared with the reliable first face map. A face base map is compared to directly obtain the comparison result of the comparison passed or failed, which can improve the accuracy of the verification of the witness, and at the same time reduce the number of calls to the third-party interface, thereby realizing the improvement of the witness by reducing the interface response time The efficiency of the verification, and the capital cost of the verification of the human certificate is saved due to the reduction of the third-party interface of the payment.

Please refer to FIG. 3. FIG. 3 is a second schematic flowchart of a method for verifying a person's certificate according to an embodiment of the application. As shown in Figure 3, the method includes the following steps S310-S380:

S310. Receive a face image and identity information, where the identity information includes an ID number.

Specifically, step S310 can refer to step S210 of the embodiment shown in FIG. 2, and the content of step S210 is included here by reference, and will not be repeated here.

S320. Determine whether a hierarchical face base map corresponding to the identity information is stored according to the identity information, wherein the hierarchical face base map is divided into the first face base map and the second face base map The second face base map is a face base map with a score greater than or equal to the second preset score threshold and less than the first preset score threshold.

Among them, the hierarchical face base map refers to the classification of the face base map according to preset standards. The higher the level, the more similar the face base map is to the user’s live face, and the more accurate the result of real-time comparison of human evidence will be. The more reliable the result of the verification of the personal certificate. The hierarchical face base map is divided into the first face base map and the second face base map, and the first face base map is a face base with a score greater than or equal to a first preset score threshold In the figure, the score of the first face base map is derived from the comparison score returned in real time by the third-party interface for verification of the first face base map, which is used to describe the first face base map Similarity with the face base map stored in the third-party interface, where the second face base map has a score greater than or equal to the second preset score threshold and less than the first preset score threshold Face base map. For example, taking the full score as 100 points, according to the comparison score value of the face image obtained from the public security interface, the face image greater than or equal to 90 points is divided into the first face base image, and the ratio of the face image is divided Face images with scores of less than 90 points and greater than or equal to 60 points are divided into ordinary base images, where the ordinary base image is verified by the public security interface against the face image as the ordinary base image, but according to the comparison score of the face image The value indicates that the face image is not so accurate. The bottom line of the ordinary base image is that the public security interface verifies the face image.

Specifically, after the server receives the face image and identity information uploaded by the terminal, it judges based on the identity information whether there is a hierarchical face base map corresponding to the identity information stored in the server’s local database, if the server stores a base map corresponding to the identity information First compare the face map with the local hierarchical face map of the server. If the hierarchical face map corresponding to the identity information is not stored in the server, call the third-party public security interface Comparing the ID verification and invoking the third-party public security interface will extend the response time of the ID verification interface on the one hand. On the other hand, the third-party public security interface is a paid call and requires a call fee.

Further, there are also two ways to determine whether a hierarchical face base map corresponding to the identity information is stored according to the identity information:

1) Check whether the face base map corresponding to the identity information is found in the database of the server. Directly according to the identity information, go to the database of the server to find whether there is a hierarchical face base map of the face map. If the amount of data in the database is relatively large, the search time will be appropriately extended.

2) By means of preset logos or keywords. The server establishes a preset identifier for the identity information stored in the database with the hierarchical face base map, and performs real-time verification of human identification. The preset identifier is first searched for according to the identity information. If the preset identifier corresponding to the identity information can be found, It is determined that the face base map corresponding to the identity information is stored in the database, and if the preset identifier corresponding to the identity information cannot be found, it is determined that the face base map corresponding to the identity information is not stored in the database. You can also set keywords. For example, if the keyword is set to "TRUE", it is determined that the face base map corresponding to the identity information is stored in the database, and the keyword is set to "FALSE", and it is determined that there is no The base map of the face corresponding to the identity information. Since the preset identifier or keyword is smaller than the amount of data in the database, the efficiency of judgment can be improved, thereby shortening the time for verification of the witness.

S330: If the hierarchical face base map is stored, determine whether the hierarchical face base map includes the first face base map.

Specifically, after the server receives the face image and identity information uploaded by the terminal, it judges whether there is a hierarchical face base map corresponding to the identity information stored in the local database of the server according to the identity information. The hierarchical face base map corresponding to the identity information is further determined whether a first face base map corresponding to the identity information is stored, wherein the first face base map has a score greater than or equal to the first preset score The face base map of the threshold value. If the server determines that the first face base map corresponding to the identity information is stored, due to the reliability of the default first face base map, the face map is compared with the first face base map and directly Obtain the comparison result verified by the witness.

S340: If the first face base map is included, compare the face map with the first face base map;

S350. Obtain a comparison result verified by a person certificate.

Specifically, if the server determines that the first face base map is stored, it compares the face map with the first face base map through face recognition technology to determine whether the identity verification of the identity verification is passed. , Regardless of whether the identity verification of the personal identification verification is passed, it will be regarded as the result of the identification verification.

S360: If the graded face base map does not include the first face base map, determine that the graded face base map only includes a second face base map;

S370. Compare the face image with the second face base image to determine whether the face image is verified.

Specifically, in the embodiment of the present application, the hierarchical face base map is divided into two levels, where one level is the first face base map with high reliability, and the other level is the relatively low reliability but also A second face base map verified by a third-party public security interface, where the second face base map has a score greater than or equal to the second preset score threshold and less than the first preset score threshold The bottom line of the face map, the bottom line of the second preset score threshold is the score of the third-party public security interface’s verification of the facial image, but it can also be higher than the third-party public security interface’s The points passed by the verification verification.

Since the hierarchical face base map is divided into two levels in this embodiment of the application, if the server determines that the hierarchical face base map is stored, and further determines that the hierarchical face base map does not include the first The face base map, it can be determined that the graded face base map only includes the second face base map whose reliability is lower than the first face base map, and the face map is compared with the second face base map. The comparison is used to determine whether the verification of the face image is passed. If the verification of the face image is passed, step S350 is entered, that is, the comparison result of the verification of the person certificate is obtained. If the verification of the face image is not passed, enter Step S380: Invoke the public security interface of the third-party interface to perform more reliable verification of the human certificate, and obtain the comparison result of the verification of the human certificate from the third-party interface.

S380. If the face map verification fails, or if the hierarchical face base map is not stored, call a third-party interface for personal identification verification to obtain a comparison result of the identification verification from the third-party interface .

Specifically, step S380 may refer to step S240 of the embodiment shown in FIG. 2, and the content of step 240 is included here by reference, which will not be repeated here.

When the embodiment of the application realizes the optimization of the verification process of the human identification, if the server receives the face image and identity information verified by the human identification, it first determines whether there is a hierarchical face base map corresponding to the identity information according to the identity information. The hierarchical face base map is stored, and it is further determined whether the hierarchical face base map includes a first face base map with higher reliability. If the first face base map is included, the face map is Compare with the first face base map to obtain the comparison result of the identification verification, or the graded face base map only includes the second face base map with relatively low reliability, if the face map The comparison with the second face base map fails, or the hierarchical face base map is not stored, and then the third-party public security interface is called for reliable verification of the person’s identification, so as to achieve the first person with higher reliability as possible The hierarchical comparison of face maps can obtain more accurate identification verification results, reduce the interface response time of calling the public security interface of a paid third party, and improve the accuracy and efficiency of identification verification.

Please refer to FIG. 4. FIG. 4 is a third schematic flowchart of a method for verifying a person's certificate according to an embodiment of the application. As shown in Figure 4, the method includes the following steps S410-S470:

S410. Receive a face image and identity information, where the identity information includes an ID number;

S420. Determine whether a first face base map corresponding to the identity information is stored according to the identity information, wherein the first face base map is a person whose score is greater than or equal to a first preset score threshold Face map

S430: If the first face base map is stored, compare the face map with the first face base map;

S440. Obtain a comparison result verified by a person certificate.

Specifically, steps S410-S440 may refer to steps S210-S230 of the embodiment shown in FIG. 2, and the contents of steps S210-S230 are included here by reference, and will not be repeated here.

S450. If the first face base map is not stored, determine whether a second face base map corresponding to the identity information is stored according to the identity information, wherein the second face base map is A face base map with a value greater than or equal to the second preset score threshold and less than the first preset score threshold;

S460. If the second face map is stored, compare the face map with the second face map to determine whether the face map verification is passed.

Specifically, in the embodiment of the present application, the face base map is also divided into two levels, where one level is the first face base map with higher reliability, and the other level is the first face base map with relatively low reliability but also the first level. The base map of the second face verified by the three-party public security interface.

After the server receives the face image and identity information verified by the human ID, it directly judges whether there is a face map based on the identity information from high to low, that is, according to the identity information, it first determines whether there is The first face base map corresponding to the identity information, if the first face base map is stored, compare the face map with the first face base map to obtain a personal ID verification directly As a result of the comparison, if the first face base map is not stored, it is further judged based on the identity information whether a second face base map corresponding to the identity information is stored, wherein the second face base map The picture shows a base map of a face with a score greater than or equal to the second preset score threshold and less than the first preset threshold. If the second face base map is stored, the face The image is compared with the second face base image to determine whether the face image verification is passed. If the face image verification passes, step S440 is entered to obtain the verification result of the person ID. If the facial image verification fails, the process proceeds to step S470, and the third-party interface is called to perform the verification of the human identification to obtain the comparison result of the verification of the human identification from the third-party interface.

S470: If the face map verification fails, or the second face base map is not stored, call a third-party interface for verification of the verification to obtain the verification result of the verification from the third-party interface .

Specifically, step S470 may refer to step S240 of the embodiment shown in FIG. 2, and the content of step 240 is included here by reference, and will not be repeated here.

In the embodiment of the present application, after the server receives the face image and identity information verified by the human certificate, it directly judges according to the priority of the face base map from high to low according to the identity information, that is, according to the identity The information first determines whether the first face base map corresponding to the identity information is stored, and if the first face base map is stored, compare the face map with the first face base map The comparison result of the verification of the personal identification is directly obtained. If the first face base map is not stored, it is further judged according to the identity information whether a second face base map corresponding to the identity information is stored. In the second face base map, the face map is compared with the second face base map to determine whether the verification of the face map is passed, and if the verification of the face map passes, the obtained face map is directly obtained According to the comparison result of the verification of the person's certificate, if the verification of the face image fails, or the first face base image and the second face base image are not stored, then the third-party interface is called for the person identification The verification is to obtain the comparison result of the verification of the person certificate from the third-party interface. Since it is first judged whether the first face base map with higher reliability is stored, the first face base map with higher reliability is stored. The situation in the figure can shorten the process of verification of the witness, thereby obtaining more accurate verification results of the verification more quickly, and further improving the accuracy and efficiency of verification.

Please refer to FIG. 5. FIG. 5 is a schematic diagram of an interaction process of the method for verifying a person's certificate according to an embodiment of the application. As shown in Figure 5, the process includes the following steps:

S5001. The front-end obtains a face image through shooting and obtains identity information through an input device, where the identity information includes an ID number.

Specifically, for real-time verification, the front-end device captures facial images through camera devices such as the front camera or rear camera, and the input component of the front-end device receives the ID number entered by the user through voice or text to uniquely identify the user. Identity information. In general, the identity information includes information such as an ID number that can uniquely determine the identity of a user. After the front-end obtains the face image and identity information required for verification of the human ID, it sends the face image and identity information to the back-end server for verification of the human ID, and obtains the human ID from the back-end server after the verification of the server’s ID The verification result is displayed.

S5002. The server receives the face image and identity information sent by the front-end, and invokes the identification verification service for identification verification.

S5003. The server invokes the identification verification service for identification verification, and determines whether the server stores a hierarchical face base map corresponding to the identity information. If the server does not store a hierarchical face base map corresponding to the identity information, go to step S5005 , Call the public security interface of the third party to verify the personal identification. If the server saves the hierarchical face base map corresponding to the identity information, enter step S5004, and use the local saved face base map for personal identification verification first to reduce the number of calls. The number of times that the public security interface of the three parties has verified the personal identification.

S5004. The server compares the received face map with a locally stored hierarchical face base map.

Specifically, if the server saves a hierarchical face base map corresponding to the identity information, the obtained face map is compared with the hierarchical face base map. Since the base map of the graded face is only different in the similarity of the base map of the face in the third-party public security interface, the comparison process of the base map of the graded face and the face map is not different. The comparison between the figure and the first face image is taken as an example to illustrate the process of comparing the face image and the graded face image. In one embodiment, the face image is compared with the first face image. The steps of comparing the face base map to obtain the verification result of the personal identification include:

Acquiring the similarity between the face image and the first face base image through face recognition;

Judging whether the similarity is greater than or equal to a preset threshold of similarity;

If the similarity is greater than or equal to the preset threshold of similarity, it is determined that the verification and comparison of the personal certificate is passed;

If the similarity is less than the preset threshold of the similarity, it is determined that the verification and comparison of the personal certificate fails.

Specifically, the comparison between the face map and the graded face base map is a process of using face recognition and then comparing. Through face recognition, according to facial features, such as facial features, specific features can be based on facial features. The position, shape, size and proportion of each part of the face are compared, and the similarity between the face map and the base map of the graded face is recognized. The similarity can be set to 80%, for example, if the face map is compared with the graded face The base map meets the similarity requirements, the face map and the graded face base map pass, the face map and the graded face base map do not meet the similarity requirements, the face map and the graded face base map do not pass, and The score of face similarity can be obtained according to specific algorithms. Further, it can also be combined with the obvious features of the detected face, for example, whether there are obvious features such as scar shape or mole in a certain position of the face. Since these obvious features are easy to distinguish, you can first detect whether there are these obvious features. These obvious features are compared to the face, and then the facial features are compared.

Furthermore, there are two statistical methods for similarity:

(1) Set the comprehensive similarity of the facial features to 100%, and each part of the facial features accounts for 20%, and calculate whether the cumulative sum of the similarities of the five senses meets the requirement of 80%;

(2) Calculate the similarity of each part of the five sense organs separately, set the similarity of each part of the five sense organs to 100%, and require the similarity of each part of the five sense organs to meet the requirements of 80%, relatively speaking, the similarity required by this method More accurate, more accurate than the result.

More specifically, the process of comparing the face map with the graded face base map includes the following steps:

S50041. The server judges whether the hierarchical face base map contains the first face base map. The first face base map can also be called a reliable base map. If the hierarchical face base map has a reliable first face base map , Enter step S50042, if the graded face base map does not contain a reliable base map, the graded face base map is only the second face base map, that is, the normal base map, and the obtained face map is compared with the normal base map. The graphs are compared, and step S5006 is entered.

Wherein, the first face base map refers to that the comparison score value obtained from the third-party public security interface stored by the server exceeds the first preset score threshold, so that the face corresponding to the identity information stored in the public security interface can be determined A face image whose base image meets the similarity requirements. Judging whether the base map is reliable is based on the score corresponding to the face base map. Therefore, there will be a corresponding score field data for each face base map. The score is generally derived from the verification of the human certificate through the public security interface. The score returned by the public security interface at the time. Taking 100 points as an example, define a high score, such as 90 points. When the score of the face image is greater than this value, the base image is considered reliable and defined as a reliable base image, which is the first face Bottom map: The face map that is lower than this score, but has also been verified by the public security interface, is defined as a normal map, which is the second face map. Further, when the service interface calls the public security interface, and the returned score is greater than or equal to the high score, the hierarchical face base map is upgraded to a reliable base map. It should be noted that the decomposed face map is the face map corresponding to the identity information that the server originally obtained through various channels and stored in advance. For example, in the business process of purchasing insurance products, the user is the first time to do this in a company After the face image submitted during the business is verified by the third-party public security interface, the server will store the obtained face image as a hierarchical face base map, and then the user needs to conduct real-time human identification verification in other businesses in the unit. The face map can be used as a hierarchical face base map for comparison during the verification process. For real-time verification, the user will be required to provide the current face map and provide some personal information of the user as identity information, such as mobile phone number, ID number, name or gender, etc., to match the user’s current face map with the base map through the identity information.

S50042: The server judges whether the generation duration of the first face base map exceeds a preset duration threshold.

Specifically, the server determines whether the generation duration of the first face base map exceeds a preset duration threshold, that is, determines the timeliness of the first face base map. If the generation duration does not exceed the preset duration threshold, the The first face base map satisfies the timeliness, the first face base map can be used as a valid base map for personal verification, and if the generation time exceeds the preset duration threshold, the first face base map does not To satisfy the timeliness, the first face base map is reduced to the second face base map. Perform real-time verification of human identification to determine whether the first face base map meets the timeliness requirements. By setting the timeliness of the first face base map, it can be ensured that when the public security system information changes, the first face base map can be updated in time, and then by ensuring that the first face base map is updated in time, so as to improve the verification Accuracy and reliability. Increase the timeliness of the reliable basemap, for example, one month, that is, the reliable basemap can be maintained for one month. After one month, the reliable basemap is downgraded to a normal basemap, and the original normal basemap is overwritten, and the score is set to a higher For low scores, take 100 points for example. For example, set to 50 points. This score can be as long as the public security interface fails the comparison. The next time the person-to-card comparison is performed, if the face information is updated, this grading person The face map can also be updated in time. The face information update here generally refers to the slight change in the contour of the face as the age grows, such as the situation where the ID card is expired and reissued.

Since the face changes with age, in order to improve the accuracy of the comparison, you can set the timeliness of the reliable base map, such as setting different durations such as one week or one month. Further, according to the appearance change law of different age groups, different time periods can be set for different age groups. For example, because the appearance of young people is in the stage of long body, the appearance changes quickly, and a shorter time limit can be set. Because of the stable appearance of young people, a relatively long time limit can be set. At the same time, a shorter time limit can be set during the age change stage. For example, the age threshold of 30, 50, or 60 years old can be set to be shorter. The time limit.

For the reliable basemap with time-sensitive setting, it is necessary to judge whether the reliable basemap is out of date. If the reliable basemap has expired, go to step S50044, if the reliable basemap has not expired, go to step S50043.

S50043. The server compares the face image with the first face base image to determine whether the comparison between the face image and the first face base image passes, and obtains the comparison result.

Specifically, when calling the back-end service's person verification interface, first determine whether the person's first face base map, which is a reliable base map, exists, and if it exists, directly compare it with this reliable base map. The result is that the comparison is not passed, and step S50045 is entered, or the comparison is passed, and step S50046 is entered. Regardless of whether the comparison result is passed or not, the comparison result is directly returned to the front end, and the third-party public security interface is not called.

S50044. The server reduces the first face base map to the second face base map.

Specifically, the server reduces the first face base map to the second face base map by modifying the score of the first face base map to be less than the first preset score threshold and greater than or equal to The value of the second preset score threshold is to modify the score of the first face base map to be below the first preset score threshold of the first face base map, for example, 100 points As an example, if the first preset score threshold is 90, the score of the first face base map can be set to 70, and step S5006 is entered to compare the face map with the second face base map.

S5005. If the server judges that there is no hierarchical face base map corresponding to the identity information, the server calls the public security interface of the third party, and sends the obtained face image to the public security interface, and then enters step S5009 to verify the identity through the public security interface. The comparison result of personal certificate verification.

S5006. The server compares the face map with the second face base map, and then proceeds to step S5007.

S5007. The server face map is compared with the second face base map. If the comparison passes, step S5008 is entered to obtain the comparison result. If the comparison fails, the second face base map is a normal base map, which is reliable If it is unstable, step S5005 is entered, and the public security interface is further invoked to verify the identity, so as to obtain a reliable identity verification result through the public security interface.

S5008. If the server passes the comparison between the face image and the second face base image, the comparison is passed as the comparison result, and the comparison result is subsequently sent to the front end.

S5009. The public security interface receives the face image and identity information sent by the server, and compares the obtained face image and identity information using the internal algorithm of the public security interface, and then enters step S5010.

Specifically, when the server interface calls the public security interface, the public security interface will return the comparison score value of the face image verified by the human certificate. This score is based on the uploaded face image and the identity information stored by the public security. The face base map is compared, and a result of the comparison passed or failed will be returned at the same time, and then the face map and the corresponding score will be saved, and the score will be returned when the public security interface is called next time When it is larger than the saved graded face basemap, overwrite the original graded face basemap and score and record the update time.

S5010: The public security interface judges whether the comparison of the face image for verification of the person's identity is passed.

Specifically, it is generally believed that the personal information such as the face map stored in the public security is stable and reliable. Due to the reliability of the face map stored in the public security, the obtained verification result is generally regarded as the final verification result. . The public security interface uses an internal algorithm to compare the face image with the face base map pre-stored in the public security to obtain the comparison result. If the public security interface passes the comparison, step S5011 is entered, and if the public security interface fails the comparison, step S5013 is entered.

S5011, if the public security interface has passed the verification and comparison of the person's certificate, go to step S5012.

S5012. The public security interface returns the comparison result and the comparison score value that have passed the comparison to the server, and proceeds to step S5015, where the server obtains the comparison result, and further returns it to the front end.

S5013. If the public security interface fails to pass the verification and comparison of the person's certificate, proceed to step S5014;

S5014. The public security interface generates a comparison result that fails the comparison, and at the same time generates a comparison score value, and returns the failed comparison result and the comparison score value to the server, and step S5015 is performed. Among them, the comparison score is compared by the public security interface based on the face image and the face base map stored in the public security interface through face recognition. The higher the score, the higher the score, the face image and the public security interface The more similar the internally stored face base maps are, it indicates that the face map is consistent with the ID, and the more reliable the verification of the identity of the witness is, and the lower the comparison score is, the more the face map is stored in the public security interface. The lack of similarity indicates that the possibility of inconsistency between the face image and the ID is increased. The reliability of the verification of the identity of the ID is relatively low, and the score is as low as the preset level, which is the result of the failed verification of the ID.

S5015. The server returns the comparison result of the obtained ID verification to the front end to complete the ID verification. Among them, the sources of the comparison results of the verification of the witnesses include the following three types:

(1) The server compares the face image with the first face base image. Due to the reliability of the base map of the first face, the comparison result is directly returned to the front end as the comparison result of the verification of the person certificate;

(2) The server compares the face image with the second face base image. If the comparison is passed, it means that the face image has a certain similarity with the second face base image, and the comparison result is returned to the terminal. If the face image and the second face base image fail to be compared, the public security interface is further called , And use the comparison result of the public security interface as the result of the verification of the personal certificate.

(3) Obtain the verification result of the person certificate through the public security interface. If the server does not have a base map, or the comparison between the face map and the second face base map fails, the server calls the public security interface to verify the identity, and returns the comparison result of the public security interface as the verification result to the front end , Go to step S5016, that is, display the comparison result of the verification of the human ID through the front end.

Further, the public security interface is called for real-time identification verification. If the public security interface passes the verification and comparison of the facial image, it can update the server's hierarchical face base map according to the score data returned by the public security interface to make the server classify people The face map is updated in time to improve the reliability of follow-up verification. The above method also includes the following steps:

S5017: The server judges whether the result of the comparison of the public security interface is obtained. If the result of the comparison of the public security interface is obtained, step S50171 is entered. If the real-time verification of the public security interface fails to pass the verification, step S5015 is entered, and the result of the verification of the identity verification is directly returned to the front end.

S50171: If the server obtains the result of the comparison of the public security interface, obtains the comparison score value returned by the public security interface, and proceeds to step S50172.

Specifically, if the server obtains the comparison result of the third-party public security interface, obtains the score of the face image included in the comparison result obtained from the third-party interface, and then proceeds to step S50172 to determine the Whether the score of the face image is greater than or equal to the second preset score threshold, if the score of the face image is greater than or equal to the second preset score threshold, the face image and its score Store it.

S50172: Determine whether the comparison score is greater than or equal to a first preset score threshold.

Specifically, it is determined whether the comparison score is greater than or equal to the first preset score threshold, that is, it is determined whether the comparison score is greater than the reliable score of the preset reliable base map, and if the comparison score is greater than The preset reliability score of the reliable basemap indicates that the face image obtained by the server this time is reliable, and step S50173 is entered, that is, the server saves the face image as the reliable basemap as the first face basemap, and saves it Update time, real-time follow-up verification. If the first face base map is still within the preset validity period, the first face base map will be used as a reliable base map for verification, due to the comparison of reliable base maps Whether the result is passed or not, it can be directly used as the result of the identification verification, thus avoiding calling the public security interface, which not only improves the efficiency of the identification verification, but also saves the cost of calling the public security interface for identification verification. For example, taking 100 points for example, if the preset reliable base map has a reliable score of 80 points, and the public security interface returns a score of 95 points, the face image can be saved as a reliable base map.

If the comparison score is less than the first preset score threshold, it is determined that the face image cannot be used as a reliable base image, and step S50174 is entered to determine whether the comparison score is greater than the score of the second face base image. The score returned by the face image is greater than the score of the originally stored second face basemap or there is no second face basemap, indicating that the face image is better than the original second face basemap or has no second face basemap. The two-face base map is more reliable than the face map in the public security interface. This face map can be replaced with the original second face base map or saved as the second face base map to improve subsequent identification Verify the efficiency and reliability. Therefore, if the server determines that the comparison score is less than the preset reliable score of the reliable basemap, step S50174 is entered.

S50174: Determine whether the score of the face image is greater than or equal to a second preset score threshold.

S50175: If the score of the face image is greater than or equal to the second preset score threshold, store the face image and its score.

Specifically, if the server determines that the score is greater than the score of the existing second face basemap, or if there is no original basemap, the basemap replaces the existing second face basemap and its score, or The face map is saved as a second face base map to improve the efficiency of subsequent identification verification and save the cost of calling the public security interface for subsequent identification verification. If the server determines that the score is not greater than the score of the second face base map, it directly returns the comparison result returned by the public security interface to the front end, that is, step S5015 is entered.

In the embodiment of the present application, by introducing a hierarchical face base map, especially the first face base map, during the verification process of the personal identification, the following beneficial effects can be brought: 1) The face base in the face base library can be made The comparison result is more accurate; 2) Reduce the number of calls to the public security interface, save capital costs and reduce interface response time; 3) The timeliness of the reliable first face base map is set to ensure that the public security system information When changing, the server's hierarchical face base map keeps up with the update in time, so as to improve the accuracy of the server's identification verification.
