Identity verifying method with video human face and digital lip movement password combined

Abstract

The invention relates to the technical field of video image processing and mode recognizing, and provides an identity verifying method with a video human face and a digital lip movement password combined. The identity verifying method mainly comprises the following steps that firstly, human face area detecting and lip area positioning preprocessing are carried out; secondly, human face features are extracted through Gabor filtering, and video human face identity verifying is carried out; thirdly, lip area features are extracted, and overall lip feature modeling and lip movement identity verifying are carried out through a hidden markov model; fourthly, password subunit dividing is carried out on the digital lip movement password, and password content recognizing and matching are carried out. According to the method, identity verifying is carried out according to the biological features and the behavior features of people, video human face information, lip movement behavior features and specific password content information are required to be included while identity recognizing and matching are conducted, multiple protection roles are played in identity verifying, stability and safety of the system can be improved, and the method has good application prospects.

Description

technical field [0001] The invention relates to the technical field of video image processing and pattern recognition, in particular to an identity verification method combining video face and digital lip movement password. Background technique [0002] With the rapid development of information technology, the ever-expanding physical and virtual activity spaces of human beings are increasingly faced with identity verification issues, such as private offices, personal smart safes, computer user login and authorized transaction systems, and so on. A safe, reliable and convenient identity authentication method can not only effectively protect the safety of personal property and information, but also bring more convenience and benefits to people's daily life. However, how to accurately identify personal identities is still a key problem to be solved in today's information age society. [0003] With its unique universality and stability, the biometric authentication technology p...

However, there is no necessary connection between the traditional personal password information and the user, and the system cannot confirm the identity of the password user

According to the literature review, the method of simultaneously using biometric characteristics and personal password information to enhance the security of the identity verification system is usually to manually enter the password and biometric characteristics for authentication and matching. This method generally requires multiple sensor devices to obtain biometric information and Password information, it is more inconvenient to use

[0006] For the direct integration of personal password information and biometric features, in the current biometric feature recognition system, the face, fingerprint, palmprint, iris and other modes that use static data input cannot dynamically implant personal security password information. Although voice signals are easy to Embed personal password information, but the read-out private password is easily detected and stolen by others, thus lacking privacy and security
