Research On Two-way Identity Authentication Method And Application Based On Dynamic Password And Face-assisted Recognition

With the development of information technology,identity authentication technology has also made great progress,but each identity authentication method has inherent deficiencies.While strengthening the security of the identity authentication method,a combination of multiple identity authentication factors should also be used to promote strengths and avoid weaknesses,thereby exerting the security effects of two-factor authentication and two-way identity authentication.This paper proposes a two-way identity authentication method based on dynamic passwords and face-assisted recognition.The main research results include the following aspects:(1)Analyze a variety of domestic and foreign identity authentication technologies and solutions,focusing on analysis and comparison of identity authentication methods such as static passwords,dynamic passwords,and biometrics;(2)Combined with the technical requirements for security protection of military-related secret information systems,the advantages and characteristics of face recognition,dynamic password,two-way authentication,and two-factor fusion technology are analyzed in view of the shortage of traditional static passwords and one-way authentication technologies,Proposed a two-way identity authentication method based on dynamic password and face-assisted recognition;(3)According to the proposed two-way identity authentication method based on dynamic password and face-assisted recognition,a scheme of two-way identity authentication system based on dynamic password and face-assisted recognition is designed.The client and the authentication server implement two-way identity authentication through the PKI mechanism,and the authentication server implements user identity authentication through the user's facial features and dynamic passwords sent by the client.At the same time,the system combines asymmetric cryptography,hash cryptography and digital signature technology to ensure the confidentiality,integrity and non-repudiation of identity authentication information;(4)According to the above design scheme,a two-way identity authentication scheme based on dynamic password and face recognition is designed and coded in detail,and verified by experiments in the network environment.At the same time,the verification results of the system were analyzed,and the system has solved the cannot be closed security problem brought by the USB port,can effectively prevent hacking Trojan user account password theft,fake website etc.Various network problems,security strength higher than that of traditional means of identity authentication,avoid caused by contact authentication products use data access risk,while ensuring the external equipment under control.
