A network authentication system with multi-biometrics

In view of the recent increase of incidents over the Internet and other networks, the role of authentication techniques to prevent unauthorized access by malicious users becomes more significant. User authentication methods can be classified into three categories: (1) methods based on human memory such as passwords, (2) methods based on physical devices such as magnetic or IC cards, and (3) methods based on biometrics such as fingerprint and iris. As the first two categories cannot escape vulnerabilities caused by forgetfulness or losses, the third category attracts much attention in these days. This paper proposes a network authentication system with multi-biometrics to support various applications where user authentication is necessary. In particular, it can provide authentication services to a workflow process that is a typical intranet application. The paper also discusses the prototype implementations developed after the proposed system and their evaluation.
