Abstract: The present disclosure relates to a method for identity authentication based on face recognition. The method comprises: initiating an interaction authentication request, which includes requested interaction tracks, and sending the interaction authentication request to an authentication client; receiving face interaction information sent by the authentication client; extracting face action tracks from the face interaction information; determining whether the face action tracks are consistent with the requested interaction tracks; if the face action tracks are consistent with the requested interaction tracks, determining that the authentication is passed, otherwise determining that the authentication fails. The above solution could prevent the authentication server from being cheated by face pictures or videos taken previously and could ensure that the face pictures or videos passing the authentication is taken in real time from a real person.
