Pattern Point Based Graphical Authentication

Internet services such as social networks, e-banking, email, cloud services, blogs, all require some form of security like user authentication. Despite the availability of advanced authentication technologies such as smart cards, biometrics or USB tokens, passwords and PINs are still the most prevalent form of user authentication. Graphical passwords are a form of user authentication on which a lot of research has been undertaken over the past decade and a variety of alternative password schemes proposed. Proposed system develops image based and pattern based authentication method. It provides user to select image and grid pattern for making pattern password. It was found that brute-force attacks were largely ineffectual in terms of time required although image analysis had a profound impact on the effective password space. Password generated by this algorithm is more memorable than pass point mechanism. Proposed system is user friendly, effective, efficient, multifactor and multilayer authentication system. It keeps resistance against information leaks, brute force attack, phishing attacks, replay attack and man-in-the-middle attack.
