Abstract

The invention provides a living body detection method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining multiple frames of to-be-detected images corresponding to a target action in response to a living body detection request, wherein the target action is an action for instructing a user to make during the living body detection; based on the feature point position information matched with the target action in each frame of to-be-detected image, determining a detection value used for representing the completion condition of the target action and corresponding to each frame of to-be-detected image; and detecting the detection value based on a detection scheme matched with the target action to obtain a living body detection result.

Description

technical field [0001] The present disclosure relates to the technical field of face recognition, and in particular, to a living body detection method, device, computer equipment, and storage medium. Background technique [0002] At present, live body detection technology is widely used in various smart devices to detect whether the "user" who is currently performing face recognition is a real user. [0003] In related technologies, when performing liveness detection, it is necessary to obtain a user's face image in real time through an image acquisition device, and then detect whether there is a face image that meets preset conditions in the face image acquired in real time, such as a face image with an open mouth , if yes, it can be determined that the liveness detection is passed. However, in the process of performing liveness detection, illegal registrants can deceive the image acquisition device by forging face images, making the security of identity verification based...
