Various embodiments of the method of the present invention are presented in terms of the above-described hardware architecture.
Referring to fig. 2, in a first embodiment of the identity verification method of the present invention, the identity verification method is applied to an authentication end, and the identity verification method includes the steps of:
step S10, receiving an authentication request including a face image to be verified, which is sent by a service end;
in the scheme, the identity verification system comprises an authentication end, a verification end and a storage end, wherein the authentication end is respectively in communication connection with the verification end and the storage end, and the verification end is in communication connection with the storage end. The authentication end establishes communication connection with the service end, when the service end processes a certain service needing identity verification, the service end packages the collected face image to be verified in an authentication request, and the authentication request comprising the face image to be verified is sent to the authentication end through a communication connection channel established with the authentication end.
The face image to be verified can be an original image acquired by the service terminal through an image acquisition device such as a camera and the like, and can also be an image obtained after preprocessing the acquired original image. In addition, the face image to be verified may be a section of video image including a face, may be one or more still images including a face that are shot, or may be one or more frames of images including a face that are captured from a video including a face of a person to be authenticated. Preferably, the face image to be verified is a static image or a frame image.
Step S20, sending the face image to be verified to a storage end, so that the storage end configures and feeds back first storage identification information corresponding to the face image to be verified;
after receiving an authentication request including a face image to be verified and sent by a service terminal, an authentication end analyzes the authentication request to obtain the face image to be verified, then sends the face image to be verified to a storage end through a communication connection channel between the authentication end and the storage end, a storage server platform stores the face image to be verified in a preset database after receiving the face image to be verified and sent by the authentication end, configures unique first storage identification information for the face image to be verified, then sends the first storage identification information to the authentication end, for the transmission safety of the first storage identification information, the storage end can encrypt the first storage identification information by using a public key in an asymmetric key generated by the authentication end, sends the encrypted first storage identification information to the authentication end, and the authentication end receives the encrypted first storage identification information, the first storage identification information can be obtained by directly adopting the private key generated by the user to decrypt.
When the requirement is stated, the authentication end does not immediately send the face image to be verified to the storage server platform after obtaining the face image to be verified, but first checks whether the face image to be verified sent by the service end meets the requirement of a preset face image, where the requirement of the preset face image may be that a set area in the face image to be verified includes a front face image and includes a complete facial image, the size of the preset face area meets the requirement of a preset size, the requirement of a preset face direction, the difference between the size of the face area contour in the face image to be verified and the size of the face image to be verified reaches a preset threshold, or at least one of the preset definition of the face image to be verified and the like. For example, the set region of the face image may be a photo collection frame of the authentication device, the face image is required to be a photo collection frame of the authentication device, the photo collection frame of the authentication device contains a front face photo of a face of a user and contains the complete five sense organs of the user, and a difference between the length and width of the collected face region of the user and the length and width of the photo collection frame is smaller than a preset threshold. And when the face image to be verified meets the preset face image requirement, the face image to be verified is sent to the storage end. When the face image to be verified does not meet the preset face requirement, particularly when multiple requirements exist in the preset face requirement, the reason which does not meet the requirements is sent to the service end, so that the service end adjusts the face image to be verified or acquires the face image to be verified again according to the reason which does not meet the requirements.
Before the authentication end sends the verification face image to the storage server platform, the living body detection can be carried out on the face image to be verified, and the living body detection can be carried out on the face image to be verified sent by the service end by adopting any existing or possible future living body detection method. The living body detection method includes, but is not limited to, an infrared living body detection method, a binocular living body detection method, a structured light living body detection method, a random instruction living body detection method, and the like, which is not limited by the present solution. When the face in the face image is a real face, the person to be verified is considered to be a living body, and the living body detection result can be 1. When the authentication end confirms that the face in the face image to be verified sent by the service end is a real face, the face image to be verified is sent to the storage end. When the authentication end confirms that the face in the received face image is a non-real face, the authentication end directly feeds back unqualified information of the living body detection of the face image to be verified to the service end.
In order to ensure the safety of the face image to be verified in the whole verification process, the face image to be verified is not stolen, so that the privacy of a user is leaked. The authentication end can encrypt the face image by adopting an asymmetric encryption algorithm, the authentication end can acquire a first public key in a pair of asymmetric encryption keys generated by the verification end, then the face image to be verified is encrypted by adopting the first public key, and the encrypted face image to be verified is generated, the asymmetric encryption algorithm comprises, but is not limited to, RSA, Elgamal, a knapsack algorithm, Rabin, D-H, ECC and the like, and the scheme does not limit the above. And then the authentication end sends the encrypted face image to be verified to the storage end so as to enable the storage end to store the encrypted face image to be verified, configures unique first storage identification information for the encrypted face image to be verified, and sends the first storage identification information to the authentication end.
Step S30, sending the first storage identification information to a verification terminal, so that the verification terminal returns the verification result of the face image to be verified after acquiring the corresponding face image to be verified from the storage terminal according to the first storage identification information;
after receiving the first storage identification information sent by the storage end, the authentication end directly sends the storage identification information to the verification end, so that after receiving the first storage identification information, the verification end obtains the face image to be verified corresponding to the first storage identification information from the storage end through a communication connection channel established between the authentication end and the storage end. After the verification end obtains the face image to be verified, the verification end calls each standard face image in the standard face image library to perform face comparison with the face image, judges whether a standard face image with the similarity exceeding a preset threshold exists in the standard face image library or not, and feeds back the verification result to the authentication end, wherein the verification result is the existence or the nonexistence of the standard face image in the standard face image library. In this embodiment, the face image conforming to the standard may be a face image that has been subjected to identity verification in advance through a correlation processing procedure, or a face image that is acquired through networking with the public security department. If the face image to be verified stored in the storage end by the authentication end is the face image to be verified encrypted by the authentication end by adopting the first public key of the verification end, the verification end acquires the encrypted face image to be verified from the storage end, and the encrypted face image to be verified is decrypted by adopting the first private key corresponding to the first public key, so that the face image to be verified is acquired.
It should be noted that the storage end sets the authority to acquire the face image to be verified, and performs authority verification on the platform or the terminal that acquires the face image to be verified. In this embodiment, the verifying end sends an obtaining request including the identification information and the first storage identification information to the storage end, after the storage end receives the obtaining request, the authority of the verifying end is judged according to the identification information in the obtaining request, specifically, whether the identification information of the verifying end is stored in a preset authority table or not is inquired according to the identification information of the verifying end, if yes, the verifying end is confirmed to have the obtaining authority, and the face image to be verified corresponding to the first storage identification information or the encrypted face image to be verified is sent to the unified verifying end. And after receiving the verification result fed back by the verification end, the authentication end forwards the verification result to the service end.
The embodiment receives an authentication request including a face image to be verified, which is sent by a service end; sending the face image to be verified to a storage end so that the storage end configures and feeds back first storage identification information corresponding to the face image to be verified; and sending the first storage identification information to a verification terminal so that the verification terminal returns a verification result of the face image to be verified after acquiring the corresponding face image to be verified from the storage terminal according to the first storage identification information. The authentication end directly sends the face image to be verified to the storage end after receiving the face image to be verified, and only sends the storage identification information corresponding to the face image to be verified. The verification end acquires the face image to be verified from the storage end according to the storage identification information, so that when the verification platform processes verification requests sent by the service end in a large batch, the verification end only sends one face image file and the storage identification information at the same time, and the occupied bandwidth of the storage identification information is far smaller than that of the face image.
Referring to fig. 3, in a second embodiment of the identity authentication method of the present invention, the identity authentication method is applied to an identity authentication system, and the identity authentication method includes the steps of:

The face image to be verified can be an original image acquired by the service terminal through an image acquisition device such as a camera and the like, and can also be an image obtained after preprocessing the acquired original image. In addition, the face image to be verified may be a section of video image including a face, may be one or more still images including a face that are shot, or may be one or more frames of images including a face that are captured from a video including a face of a person to be authenticated.

After receiving the face image to be verified sent by the authentication end, the storage server platform stores the face image to be verified in a preset database, configures unique first storage identification information for the face image to be verified, and then sends the first storage identification information to the authentication end. After receiving the first storage identification information sent by the storage end, the authentication end directly sends the first storage identification information to the verification end.
It should be noted that, for the purpose of secure transmission of the first storage identification information, the storage end may encrypt the first storage identification information by using a public key in an asymmetric key generated by the authentication end, and send the encrypted first storage identification information to the authentication end, and the authentication end receives the encrypted first storage identification information, and directly decrypts the first storage identification information by using a private key generated by the authentication end, so as to obtain the first storage identification information, and then sends the first storage identification information to the verification end.

In this embodiment, after the authentication end obtains the face image to be verified, the authentication end does not immediately send the face image to be verified to the storage server platform, but first checks whether the face image to be verified sent by the service end meets a preset face image requirement, where the preset face image requirement may be that a set region in the face image to be verified includes a front face image and includes a complete facial image, a size of the preset face region meets a preset size requirement, a preset face direction requirement, a difference between a contour of the face region in the face image to be verified and a size of the face image to be verified reaches a preset threshold, or at least one of a preset definition of the face image to be verified and the like. For example, the set region of the face image may be a photo collection frame of the authentication device, the face image is required to be a photo collection frame of the authentication device, the photo collection frame of the authentication device contains a front face photo of a face of a user and contains the complete five sense organs of the user, and a difference between the length and width of the collected face region of the user and the length and width of the photo collection frame is smaller than a preset threshold. And when the face image to be verified meets the preset face image requirement, the face image to be verified is sent to the storage end.
When the authentication end confirms that the face image to be verified does not meet the preset face requirement, particularly when multiple requirements exist in the preset face requirement, unqualified information and unqualified reasons are sent to the service end together, so that the service end adjusts the face image to be verified according to the unqualified reasons or acquires the face image to be verified again. For example, if the detected face image to be verified does not contain the complete facial features of the user, the blocking phenomenon of the facial features of the face image sent by the service end can be reminded; if the face in the face image to be verified is detected to be too large or too small, the face in the face image at the service end is reminded to be too large or too small, so that an operator at the service terminal can adjust the distance from the user to the camera; and if the face of the face image is detected to be inclined, reminding the business terminal of the inclination of the face image, and the like. The reminder comprises one or more combinations of a text reminder, a voice reminder, an image reminder and the like.
In the embodiment, preliminary form detection is performed on the face image to be verified sent by the service terminal, only the face image to be verified meeting the requirement is stored in the storage terminal, and then the subsequent identity verification process is performed, so that the situation that the face image to be verified, the form of which does not meet the requirement, flows into the subsequent verification process to cause that the verification load of the verification terminal is too heavy is avoided, and after the preliminary form detection is failed, the reason why the detection is not passed can be fed back to the service terminal, so that the service terminal can pertinently adjust the face image to be verified according to the reason why the detection is not passed, and the passing rate of form detection of the subsequently sent face image to be verified is improved.
