An efficient and secure biometric remote user authentication scheme using smart cards

Remote user authentication schemes are widely investigated recently. This paper points out some existent problems in smartcard based schemes. As a comprehensive solution, a novel authentication scheme using two-variant hashing technique and fingerprint-biometric is presented. Security analysis shows that the proposed scheme provides secure, robust, and trustworthy remote authentication over insecure network. Moreover, computational costs and efficiency of this scheme are encouraging for practical implementation in the resource-constraint environment.
