Biometric information-based authentication method and apparatus

Abstract

Disclosed is a biometric information-based authentication method and apparatus, in which various types of biometric information extracted from a user are used. According to an embodiment of the present disclosure, the authentication method includes: checking first biometric information based on a physical characteristic of a user and second biometric information varying with a biological characteristic of the user; constructing a reference composite polynomial on the basis of one or more feature points respectively detected from the first and second biometric information and generating and storing security information using the reference composite polynomial; checking first and second measured biometric information of the user; constructing a detection composite polynomial on the basis of one or more feature points detected from the first and second measured biometric information and generating authentication information using the detection composite polynomial; and performing authentication of the user by comparing the security information with the authentication information.
