Abstract: A password is a secret word or combination of alphabets used for user authentication to establish self identity. This password should be kept secret from those not allowed to access. Now-a-days data security is the most describing problem. Token based authentication like Smart card, Biometric based authentication like iris, fingerprint, facial, Knowledge based authentication like text based and Image based password. Graphical password are more secure than the text password because they are easy to remember and hard to crack. In this paper we will study survey of different types of Recall-based graphical user authentication algorithm based on usability attributes and attack pattern those we found and also different factors affecting to it. We will also implement multi-line grid algorithm.
Keywords: Graphical Password, Attack Pattern, User authentication, pure recall-based algorithm, cued recall-based algorithm, multi-line grid algorithm.
