Patent attributes
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a payment based on a face recognition are provided. One of the methods includes: acquiring first face image information of a target user; extracting first characteristic information from the first face image information, wherein the first characteristic information includes head posture information of the target user and gaze information of the target user; determining whether the target user has a willingness to pay according to the head posture information of the target user and the gaze information of the target user, including determining whether an angle of rotation in each preset direction is less than an angle threshold and whether a probability value that a user gazes at a payment screen is greater than a probability threshold; and in response to determining that the target user has a willingness to pay, completing a payment operation based on the face recognition.
