PKI Identity Authentication System Based On Fusing Face Recognition As Registration Factor

In recent years,the Internet and computer applications,fast forward,electronic identity authentication technology has become an important means to ensure the safety of network applications.In the electronic identity authentication technology,based on PKI(public key cryptography infrastructure)technology to USBKEY authentication medium authentication method is a trusted and common identity authentication technology,but based on USBKEY authentication method also has some shortcomings: First,the certification medium there are loans,misappropriation or abuse of the problem;the second is the risk of loss of certification media,such as the certificate is not promptly revoked may bring security risks;the third can not prove that the user personally to the scene operation.At the same time,based on the face of biometric authentication is currently using more technology,it is the only user's biological characteristics to authenticate the identity of the entity,the user must personally to complete the certification,but this certification is also inadequate: First,in the process of identity authentication,biometrics in the network to pass the attacker to steal,replay the security risk of attack;and second,biometric technology can not provide encryption,integrity protection and other more comprehensive security protection.In this paper,PKI technology and face biometrics technology were studied,in the PKI identity authentication system into the face biometrics as a certification factor,on the one hand through the integration of human face recognition,an increase of the user to the scene of the operation of the certification capabilities to improve the authenticity of identity authentication;On the other hand,dynamic indexing and downloading of user certificates and keys through facial biometrics reduce the risk of key loss,enhance the ability of anti-loss of media,reduce the requirement of media control and improve the convenience of users.The PKI authentication system,which integrates face recognition as a certification factor,has the advantages of safety,ease of use and low cost,and has wide application prospect.The work done in this paper is as follows:Based on the research of PKI authentication technology and face biometrics,this paper designs the identity authentication system which integrates face recognition as the authentication factor,Firstly,the topology and working principle of the system are introduced,the design of the system architecture is completed,and the function modules are described.And then the security of the system to do a specific analysis,and verify the public key cryptography and biometric fusion of the feasibility of the certification method.
