Abstract
Some embodiments of this specification provide face liveness detection computer-implemented methods, devices, and media. In an example, multiple face images continuously captured for a first user are obtained. Two face images are selected from the multiple face images for a target attribute in one or more predetermined image attributes, where a degree of difference between two attribute values of the target attribute corresponding to the two face images satisfies a predetermined criterion. Both of the two face images are input into a pre-trained face liveness detection model corresponding to the target attribute to obtain a detection result corresponding to the target attribute.
