Abstract

Recently, it is spread a service through an open network, such as non-face-to face trading. It is constructed a PKI (Public Key infrastructure) for these service. An authentication using PKI based on an own of private key. Therefore the PKI authentication has a threat of improper use. And it has a problem of Cost of verification of CRL for a great many users, such as a government service. This paper presents a biometrics-based personal authentication system in which a smart card, a Public Key Infrastructure (PKI) such as an X.509 certificate, and biometric verification technologies are combined. So it is able to keep an operation security without the CRL verification. We have developed a prototype system in which the system is applied to a biometric management system. The proposed system can also be applied to some public key platforms such as the ‘electronic signature act’ and the next ‘e-Passport’, because our system has been developed on equivalent platforms.<br>
