APPARATUS AND METHOD FOR AUTHENTICATING BIOMETRIC INFORMATION
First Claim
1. A system for biometric authentication, comprising:
- a plurality of databases that separately stores each of a plurality of separated biometric information generated by separating the registered biometric information of a user and separately manages each of them;
a removable storage unit that stores a plurality of identifiers corresponding to each of the plurality of the separated biometric information; and
a biometric authentication apparatus that authenticates the user by receiving an input of biometric information for authentication from the user and comparing it to the registered biometric information,wherein the biometric authentication apparatus comprises a biometric information composing unit that makes a request for the separated biometric information to the plurality of databases using a plurality of identifiers that are read from the removable storage unit and composes the registered biometric information using the plurality of separated biometric information provided by the plurality of databases according to the request, and an authenticating unit that compares the composed registered biometric information to the biometric information for authentication and proceeds with the authentication.

Abstract
A method for biometric authentication and a system using the same are provided. The biometric authentication system of the present invention separates pre-registered biometric information of a user into a plurality of separated biometric information, disperses them to a plurality of databases and manages them. Accordingly, when a user authentication process is needed, the biometric authentication system performs an authentication by obtaining the separated biometric information that are managed by a plurality of databases and composing registered biometric information. The present invention reduces the risk of leakage of biometric information of a user due to hacking or theft since it allows biometric information to be separated, disperse and managed, which conventionally is store as a single file on a server, a database or a security token.
