Abstract

The invention discloses a face unlocking method based on motion analysis. The method comprises the steps that image information is collected, if the image information contains face image information, face recognition is conducted on the face image information, and a recognized face image is obtained; if the recognized face image is matched with a preset face image, and prompt information is sent out to prompt a user to make a corresponding face motion according to the prompt information; a face motion image of the user is collected, and the face motion of the user is analyzed; if the face motion of the user is matched with the face motion which is made by the user according to the requirement of the prompt information, a terminal device is unlocked. According to the face unlocking method, users without permissions are prevented from logging in to the terminal device through pictures or videos in a cracking mode, and face unlocking safety is improved. The invention further discloses a face unlocking device and terminal based on motion analysis.

Description

technical field [0001] The present invention relates to a technology for unlocking a terminal, in particular to a method and device for face unlocking based on motion analysis. Background technique [0002] Face unlocking is a means of authority management through face recognition or face verification technology. The terminal system can use the biometric feature of face as a password for authority protection. Face unlocking has applications in many fields: such as the unlocking of smartphones, the unlocking of access control in banks and prisons, and so on. Most of the existing face unlocking systems use such as figure 1 frame shown. Firstly, several face images of a user with certain authority are collected offline, and the user’s face feature library is established after preprocessing and feature extraction; when there are multiple authority users, a separate feature library will be established for each user; when unlocking online , the collected image information, afte...
