Embodiment Construction

[0040] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] After analysis, another main difference between photos and real people is: real people can have various expression changes, while a single photo can only have one expression; although multiple photos may have multiple expressions, the change of expression is not continuously.

[0042] Based on the above analysis, the core of the present invention is to provide a facial recognition system based on facial expression recognition, which requires the user to make at least two facial expressions during the authentication process. Since photos cannot change facial expressions, it is possible to distinguish between a single photo and real person. At the same time, face tracking is used to determine that the expression changes are ...

Abstract

The invention provides an identity authentication method and an identity authentication system based on a human face, which are used for solving the problem of distinguishing real persons from photos in the authentication process of the human face. The identity authentication method comprises the following steps of: carrying out human face authentication and facial expression recognition on a current frame image; carrying out comprehensive authentication on a human face authentication result and a facial expression recognition result of a continuous multiframe according to a preset strategy; and if the comprehensive authentication result is human face authentication pass and at least comprises two expressions, passing the identity authentication of the human face. According to the identity authentication method and the identity authentication system provided by the invention, by combining the expression recognition with human face recognition, the authentication performance is improved and the phenomenon that a jactitator passes the authentication by using a photo is avoided.

Description

technical field [0001] The invention relates to the technical field of pattern recognition, in particular to a face-based identity authentication method and system. Background technique [0002] Biometric recognition technology is a science that utilizes individual's unique physiological and behavioral characteristics to achieve identity recognition and (or) individual verification purposes, such as recognition of face, fingerprint, palm print, iris, voice, etc. In the biometric identification technology, the recognition technology characterized by human face has developed very rapidly in recent years. [0003] With the development of face recognition technology, face recognition-related application systems are gradually increasing. As an application system related to face recognition technology, face authentication systems have achieved more and more applications in automatic access control, face login, etc. . The face authentication system uses the camera to collect the ...
