METHOD AND SYSTEM FOR SECURELY STORING BIOMETRIC PARAMETER IN DATA BASE, AND METHOD FOR AUTHENTICATING USER BY SECURELY STORING BIOMETRIC PARAMETER IN DATA BASE

摘要

PPROBLEM TO BE SOLVED: To achieve secure authentication based on biometric parameters. PSOLUTION: Biometric parameters to be registered are acquired from a user, and are encoded as a syndrome. A hash function is applied to produce a registered hash, which is then stored in a data base. The registered syndrome is decoded using a syndrome decoder and authenticated user biometric parameters to produce decoded biometric parameters. A hash function is applied to the decoded biometric parameters to produce an authenticated hash. Whether the user access is granted or not is determined by comparing the authenticated hash and the registered hash. PCOPYRIGHT: (C)2006,JPO&NCIPI
