Face verification method and apparatus, server and readable storage medium

A face verification system, comprising a processor and a non-transitory computer-readable storage medium storing instructions executable by the processor to cause the system to perform operations comprising:

• acquiring a two-dimensional face image and a three-dimensional face image for face verification of a target user;
• performing face recognition on the acquired two-dimensional face image with respect to the target user to obtain a result of the face recognition;
• in response to the result of the face recognition indicating that the face recognition is successful, performing three-dimensional reconstruction on the acquired two-dimensional face image to obtain a reconstructed three-dimensional face image;
• performing liveness detection on the acquired three-dimensional face image to determine whether a face in the acquired three-dimensional face image corresponds to a live person;
• in response to determining that the face in the acquired three-dimensional face image corresponds to a live person, comparing the reconstructed three-dimensional face image with the acquired three-dimensional face image to determine a similarity value;
• and
• in response to the determined similarity value satisfying a condition, determining that the two-dimensional face image corresponds to the target user.

A non-transitory computer-readable storage medium for face verification, configured with instructions executable by one or more processors to cause the one or more processors to perform operations comprising:

• acquiring a two-dimensional face image and a three-dimensional face image for face verification of a target user;
• performing face recognition on the acquired two-dimensional face image with respect to the target user to obtain a result of the face recognition;
• in response to the result of the face recognition indicating that the face recognition is successful, performing three-dimensional reconstruction on the acquired two-dimensional face image to obtain a reconstructed three-dimensional face image;
• performing liveness detection on the acquired three-dimensional face image to determine whether a face in the acquired three-dimensional face image corresponds to a live person;
• in response to determining that the face in the acquired three-dimensional face image corresponds to a live person, comparing the reconstructed three-dimensional face image with the acquired three-dimensional face image to determine a similarity value;
• and
• in response to the determined similarity value satisfying a condition, determining that the two-dimensional face image corresponds to the target user.
