Abstract: The present disclosure provides an identify authentication system. The authentication system includes an authentication terminal configured to issue an identity authentication request; and, an authentication server that is connected to the authentication terminal to receive the identity authentication request. The authentication server is configured to acquire one or more identity authentication scenarios from authentication scenarios based on the identity authentication request, and generate and transmit an authentication form after acquiring the authentication scenario. The authentication terminal is configured to submit the identity authentication information to the authentication server based on the authentication form. The identity authentication information includes basic user information and an authentication scenario image and video including a user. The authentication server is further configured to authenticate the user's identity based on the identity authentication information.
