Abstract

The invention discloses a human face living body detection method and device, human face living body detection equipment and a medium. The method comprises the following steps of controlling a position mark to be displayed on a screen; controlling the display of a moving track of the position mark, and controlling a shooting device to shoot a video of a user; and determining the matching degree between the position change track of the nose tip of the user in the video and the movement track of the position mark, and thereby obtaining a first human face living body detection result. According to the method, the living body detection result is obtained based on the matching degree between the change track of the nose tip position of the user and the movement track of the position mark, so safety of video living body detection is effectively improved.

Description

technical field [0001] The present invention relates to detection technology, in particular to a human face liveness detection method and device, a human face liveness detection device and a medium. Background technique [0002] Face liveness detection refers to the technology of judging whether the face in a given image or video is from a real person or from a spoofed face (mask, printed photo, photo displayed on the screen or video clip played, etc.). Face liveness judgment is an important anti-attack and anti-fraud technical means, which is widely used in banking, insurance, Internet finance, e-commerce and other industries and occasions involving remote identity authentication. [0003] The existing face liveness detection methods are mainly divided into two categories according to the input method: picture liveness detection methods and video liveness detection methods. [0004] For the picture living method, the input is generally one or several pictures, the amount o...
