A fingerprint-based user authentication scheme for multimedia systems

In the applications of multimedia communication, besides the content-based authentication, the user authentication is also an important issue to protect the multimedia resources. In this paper, we improve a fingerprint-based remote user authentication proposed by Lee, Ryu and Yoo (Electron. Lett., vol. 38, no. 12, pp. 554-555, 2002). The scheme is novel by introducing a fingerprint-based verification into authentication scheme using smart cards. However, their scheme is vulnerable to masquerade attack. In this article, we propose an improved scheme to enhance the security of their scheme in order to overcome the vulnerability. Our scheme protects the host resources which can only be accessed by authorized users
