Variable Biometric Information-Based Complex Authentication System and Complex Authentication Method Using the Same

摘要

A complex authentication system that uses personal variable biometric information which changes according to times and environments, and a complex authentication method using the same are disclosed. The variable biometric information-based complex authentication system includes: a mobile terminal configured to collect variable biometric information; a variable biometric information management server configured to store the variable biometric information received from the mobile terminal; and an agent server configured to, when the mobile terminal requests a login command regarding the ID, verify validity of the login command regarding the ID based on the variable biometric information. Accordingly, even if biometric information used in an authentication procedure is leaked, a damage resulting therefrom can be inhibited, and security of the authentication procedure can be enhanced by combining different types of variable biometric information or by combining variable biometric information of a plurality of users.
