User-oriented pseudo biometric image based one-time password mechanism on smart phone

Abstract

User authentication procedures should be enhanced its security on Smart phone. And more secure system should be implemented to minimize the user's privacy disclosure. Although image-based authentication mechanism was introduced recently, replay attack is also possible on existing one-time password based authentication system. In this paper, we implemented pseudo biometric image based OTP generation mechanism, which uses transformation function on captured biometric image from each user for providing enhanced secure authentication service on smart phone. © 2011 Springer-Verlag Berlin Heidelberg.
