Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for liveness detection are provided. One of methods includes: displaying an image to a user, and capturing a face image of the user while displaying the image to the user; determining an eye image of an eye of the user based on the face image; extracting a to-be-verified image from the eye image of the user, wherein the to-be-verified image is reflection of the displayed image in the eye of the user; comparing the displayed image with the to-be-verified image to determine whether the to-be-verified image matches the displayed image; and performing liveness detection on the user based on a result of comparison.
