Description

Method, device and terminal for realizing authentication
Technical Field

Currently, as devices for processing daily affairs and life entertainment, terminals (mobile phones, tablets and the like) store more and more user information, wherein the privacy of users is involved, such as private logs of users, personal audio and video files, important work logs or memorandum logs and the like. In order to ensure the security of the privacy of the user, the screen display of the terminal and the application in the terminal need to be authenticated to obtain corresponding authority, so that the terminal or the application can be used. Taking the terminal screen display as an example, the privacy security of the user and the locking of the terminal screen display are ensured for example, and the conversion from simple sliding unlocking and pressing unlocking to higher security face recognition, track patterns, PIN codes, digital passwords and the like is realized. Taking the screen display unlocking through the face recognition as an example, assuming that the terminal is set to adopt the face recognition technology to perform the screen display unlocking, the face image information of the user is stored in the terminal in advance; when the screen display unlocking is carried out, the terminal camera device shoots a face image of a user unlocking the terminal, image matching is carried out through an image feature extraction method, and the screen display unlocking is carried out on the terminal when the situation that the user unlocking the terminal is the same as the user storing the face image information is determined.
Face identification, track pattern, PIN code, digital code etc. have guaranteed user's privacy to a certain extent, but current unlocking method still has certain problem: for example, face recognition has a problem that it can be unlocked by using a still picture; PIN codes, track patterns and digital passwords have the problem of being easy to crack.
In summary, in the existing unlocking method, the face recognition can adopt static picture unlocking, PIN codes, track patterns and digital passwords are easy to crack; the authentication method applied in the terminal is basically the same as the screen display unlocking authentication method, so that the safety of the user privacy can not be guaranteed even if the user identity is authenticated by the existing authentication method.
