摘要

A face liveness recognition method includes: obtaining a target image containing a facial image; extracting facial feature data of the facial image in the target image; performing face liveness recognition according to the facial feature data to obtain a first confidence level using a first recognition model, the first confidence level denoting a first probability of recognizing a live face; extracting background feature data from an extended facial image, the extended facial image being obtained by extending a region that covers the facial image; performing face liveness recognition according to the background feature data to obtain a second confidence level using a second recognition model, the second confidence level denoting a second probability of recognizing a live face; and according to the first confidence level and the second confidence level, obtaining a recognition result indicating that the target image is a live facial image.

說明書

FIG. 1 is an application environment diagram of a face liveness recognition method according to an embodiment of the present disclosure. Referring to FIG. 1, the face liveness recognition method is applicable to a face liveness recognition system for performing facial recognition with face liveness detection. The face liveness recognition system includes a terminal 110 and a server 120. The terminal 110 and the server 120 are connected through a network. The terminal 110 may be configured to perform the face liveness recognition method. The terminal 110 may also acquire, from a real scene, a target image including a human face, and send the acquired target image to the server 120 so that the server 120 performs the face liveness recognition method. The terminal 110 may specifically be a mobile phone, a tablet computer, a notebook computer, or the like, or at least one thereof. The server 120 may specifically be an independent server or a server cluster that includes multiple independent servers.
