Method for achieving user authentication by utilizing camera

Abstract

The invention discloses a method for achieving user authentication by utilizing a camera. The method comprises the following steps: (1) pre-collecting and storing a facial image of a user, (2) performing vivo detection on a facial image of a current user through the camera in the field use process, executing the step (3) if the detection succeeds, and prompting that the detection fails if not, (3) performing field photographing on the current user through the camera and performing storing, (4) comparing the stored facial image of the user with the pre-collected facial image of the user to obtain the degree of similarity, and (5) comparing the degree of similarity and a preset threshold value and determining whether the two compared facial images belong to the same person, wherein it is determined that the two compared facial images belong to the same person if the degree of similarity is greater than or equal to the preset threshold value, and the authentication cannot be passed if the degree of similarity is smaller than the preset threshold value. According to the method for achieving the user authentication by utilizing the camera, because dual detection is performed through a facial recognition system and the vivo detection, the situation of easily invading the system can be effectively controlled, and the security of user data is promoted.

Description

technical field [0001] The invention relates to the research field of computer identity verification, in particular to a method for realizing user identity verification by using a camera. Background technique [0002] The traditional identity verification methods mainly include passwords, fingerprints, tokens or magnetic cards, etc., but there are certain defects, for example: (1) The password is the most widely used device startup verification, and the user sets the startup password in the system setting module after the startup. When the user turns on the device next time, the correct password can be entered to open the device. Although the password method is more convenient, people's memory will often be forgotten with the passage of time or the increase in memory; if the password is written down in the notebook, it is easy to be stolen or lost; (2) Token or magnetic card to verify identity , the user installs an electronic identity verification system on the device, and...

Problems solved by technology

This verification method solves the above-mentioned problems of being easily forgotten, stolen or lost, but there are also some problems at the same time. For example, the quality problem when the image is taken will affect the reliability of the identity verification. Portraits or sculptures to replace real human faces, etc.
