Two-Way Real-Time Authentication System Based on Dynamic Password and Multi-biometric

In this paper, we have designed a high-security two-way real-time authentication system using dynamic password and multi-biometric to solve the shortages of traditional information system. In order to guarantee the security of fingerprint eigen value and facial feature value, we encrypt them with dynamic password. By the method of two-way authentication, it not only can ensure authentication server to recognize the users, but also guarantee the users to verify authentication server, effectively prevent information from leakage caused by counterfeit servers and tampering. When we use the system, the server gets face feature extraction information from the client every three minutes, to protect the irreplaceable nature of the user. The technology of role-based access control simplifies license management. The technologies of MPEG-4 and local directional mode LDP are used to deal with the information of human face, to quantify the characteristics of the face value.
