AN ENHANCED MULTILEVEL AUTHENTICATION SCHEME USING GRAPHICAL PASSWORDS

With the advent of internet, various online attacks have been increased and among them the most popular attack is phishing. An enhanced multilevel authentication scheme using graphical passwords focuses on solving the problem of phishing using Visual Cryptography. Visual Cryptography is explored to preserve the privacy of image by decomposing it into two shares that are stored in separate database servers such that the original image can be revealed only when both are simultaneously available that is we are achieving mutual authentication by this. Using this approach one can cross verifies both the user and the website as of genuine or not. Once the user finds the legitimate, he logs into the website using his password.In this paper, we have proposed Multi-level Authentication using graphical passwords, which is a generalization to improve the security from online attacks . In this approach we could achieve mutual authentication in which both the user and the website are authenticated.
