A one-card-pass user authentication scheme using image morphing

摘要

A novel smart card user authentication scheme is proposed in this paper. It is the first authentication scheme that can achieve "one-card-pass" functionality, that is, an authorized card user may register with any department in an organization, and then, by just passing the face-to-face authentication but without conducting any extra registration, the card user can use his/her card to gain different services from all authorized departments in this organization. To enhance the security, image morphing and de-morphing techniques are used in our proposed scheme. Both the theoretical analyses and experimental results show that our proposed scheme is secure and very simple to implement.
