A Robust Graphical-Based Authentication for Knowledge Level Using Persuasive Cued Click Points
S. Subadra, S. Ushanandhini
Abstract: The graphical based technique is mainly used for authentication purpose. The purpose of this paper is increasing the security space and usability and avoiding the weakness of conventional password. The graphical based password technique uses persuasive cued click point. This persuasive Cued click points was designed to reduce patterns and reduce the usefulness of hotspots for attackers. An important usability goal for authentication systems is to support users in selecting better passwords, thus increasing security by expanding the effective password space. In click-based graphical passwords, poorly chosen passwords lead to the emergence of hotspots. The graphical password technique use robust discretization method, this discrete method is used to determine a click points tolerance square & corresponding grid. The click-based graphical passwords, encourage users to select more random, and hence more difficult to guess, click-points.
