Identity authentication method and apparatus

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• obtaining an audio/video stream, wherein the audio/video stream is generated by a target object to be authenticated, the target object associated with a user;
• determining whether a lip reading component and a voice component in the audio/video stream are consistent;
• in response to determining that the lip reading component and the voice component are consistent, performing voice recognition on an audio stream in the audio/video stream to obtain voice content, and using the voice content as an object identifier of the target object;
• obtaining a model physiological feature corresponding to the object identifier from object registration information;
• performing physiological recognition on the audio/video stream to obtain a physiological feature of the target object;
• comparing the physiological feature of the target object with the model physiological feature to obtain a comparison result;
• and
• in response to the comparison result satisfying an authentication condition, determining that the target object has been authenticated.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• obtaining an audio/video stream, wherein the audio/video stream is generated by a target object to be authenticated, the target object associated with a user;
• determining whether a lip reading component and a voice component in the audio/video stream are consistent;
• in response to determining that the lip reading component and the voice component are consistent, performing voice recognition on an audio stream in the audio/video stream to obtain voice content, and using the voice content as an object identifier of the target object;
• obtaining a model physiological feature corresponding to the object identifier from object registration information;
• performing physiological recognition on the audio/video stream to obtain a physiological feature of the target object;
• comparing the physiological feature of the target object with the model physiological feature to obtain a comparison result;
• and
• in response to the comparison result satisfying an authentication condition, determining that the target object has been authenticated.
