Chaotic hash-based fingerprint biometric remote user authentication scheme on mobile devices

This paper presents an efficient and practical chaotic hash-based fingerprint biometric remote user authentication scheme on mobile devices e.g. cell phone and PDA. Our scheme is completely based on the new family of one-way collision free chaotic hash functions, which are much efficient than modular exponentiation-based authentication schemes e.g. RSA. Proposed scheme is two-factor authentication scheme and a user has to identify him with: something he knows (e.g. password) and something he is (e.g. fingerprint biometric). Security analysis shows that the proposed scheme provides secure, robust, and trustworthy remote authentication of mobile users over insecure network. In addition, computational costs and efficiency of the proposed scheme are encouraging for the practical implementation in the real environment. (C) 2006 Elsevier Ltd. All rights reserved.
