Abstract

The embodiment of the invention discloses a living body detection and auxiliary living body detection method, device and equipment, the living body detection method can receive a to-be-detected videoshot and uploaded by terminal equipment, and in the process of shooting the to-be-detected video by the terminal equipment, a vibration motor of the terminal equipment is in an on state; sequentiallyselecting multiple frames of images from the to-be-detected video, and determining the jitter degree of the to-be-detected video in the shooting process based on the multiple frames of images; and judging whether the to-be-detected video is a real shot living video based on the jitter degree.

Description

technical field [0001] This document relates to the field of computer technology, and in particular to a method, device and equipment for living body detection and auxiliary living body detection. Background technique [0002] With the development of artificial intelligence technology, face recognition has been widely used in the field of identification. In order to prevent criminals from pretending to be legitimate users to deceive the face recognition system to endanger the property, personal and safety of legitimate users through photo printing, screen recapture and head mask, etc., related technologies also introduce liveness detection in face recognition. technology. Specifically, in face recognition, by shooting videos containing live actions such as blinking, opening mouth, and shaking the head, and by means of silent live bodies, it is possible to defend against attacks such as photo printing, screen recapture, and head membranes. [0003] However, the liveness det...
