Identity Authentication Method, Identity Authentication Device, And Terminal

An identity authentication device, comprising:

• an information providing module, configured to provide an authentication object with prompt information configured to prompt the authentication object to make a target authentication action, wherein the target authentication action comprises at least one of a facial expression and a head action;
• a first collecting module, configured to collect at least one frame of image;
• a detecting module, configured to detect whether authentication action information of the authentication object in the at least one frame of image matches reference action information generated by a target object making the target authentication action;
• and
• a result determining module, configured to determine that the authentication object passes an identity authentication in a case that a detection result of the detecting module indicates that the authentication action information of the authentication object matches the reference action information.

A terminal, comprising:

• one or more processors;
• and
• a memory stored with one or more programs configured to be executed by the one or more processors, wherein the one or more programs comprise an instruction to:
• provide an authentication object with prompt information configured to prompt the authentication object to make a target authentication action, wherein the target authentication action comprises at least one of a facial expression and a head action;
• collect at least one frame of image;
• detect whether authentication action information of the authentication object in the at least one frame of image matches reference action information generated by a target object making the target authentication action;
• and
• determine that the authentication object passes an identity authentication in a case that the authentication action information of the authentication object matches the reference action information.
