A Three Factor Authentication System for Smartcard Using Biometric, Visual Cryptography and OTP

摘要

In this paper, we use an authentication system that combines Biometrics, Visual cryptography and One-Time password (OTP). We propose a basis matrix construction method for generating shares in visual cryptography technique. Generated shares are in mutually orthogonal groups so that only shares from the same group can reveal the original image. The system provides the user a share of the biometric data and keeps the other share in the server itself. The security of our scheme is based on biometric verification using visual cryptography and hash of a OTP. Therefore, the scheme is appropriate to be used in applications such as smart card and device authentication systems.
