Collaborative fingerprint authentication by smart card and a trusted host

The smart card is an important component in e-commerce security. In a previous CCECE paper, we introduced the idea for verification of the ownership of a smart card using fingerprints. An owner´s fingerprint is registered into a smart card. When using a smart card on a computer, the card software will match the user´s fingerprint with that stored in the card. This paper describes a continuation of this research. Our goal is to extend the role of the smart card to become an active authenticator for participation in the fingerprint authentication process. The heart of the problem lies in the limited computing power of the card´s processor. This paper reports the detailed descriptions of the design, implementation and experiments
