Multi-factor authentication process using more than one token with watermark security

Abstract

Authentication is the process of verifying a user's credentials when they are requesting services from any secure system. A simple authentication only involves a username and password, which can be easily deciphered. Hacking technologies have become more diversified and advanced, security and authentication have become unable to rely on ID and password-based authentication alone. Single-factor authentication using an ID and password has been found to be vulnerable to malware attacks, replay attacks, offline brute force attacks, key logger trojans, dictionary attacks and shoulder surfing. Adding a strong factor will reduce the chances of the user's identification from being hacked. This paper proposes a new multifactor authentication scheme, which combines with hard token, password and biometric token with watermark image. Compared with the previous schemes this scheme has higher security in remote authentication and lower communication complexity. © 2013 Springer Science+Business Media Dordrecht.
