User Authentication Based On Persuasive Cued Click Points with Sound Signature

Various graphical password schemes have been proposed as alternatives to text-based passwords. Researches have shown that text-based passwords are fraught with both usability and security problems that make them less than desirable solution. Psychology studies have revealed that the human brain is better at recognizing and recalling images than text. Graphical passwords are intended to capitalize on this human characteristic in hopes that by reducing the memory burden on users, coupled with a larger full password space offered by images, more secure passwords can be produced and users will not resort to unsafe practices in order to cope. Cued click points (CCP) is a click-based graphical password scheme, a cued-recall graphical password technique. Users Click on one point per image for a sequence of images. The presence of hotspots remains as an issue in CCP. We propose a new clickbased graphical password scheme for authentication called Persuasive Cued Click Points (PCCP) with sound signature. A password consists of one click-point per image for a sequence of images. The next image displayed is based on the previous clickpoint so users receive immediate implicit feedback as to whether they are on the correct path when logging in. In order to provide greater security, the concept of viewport is introduced here. The viewport is positioned randomly, rather than specifically to avoid known hotspots. PCCP offers both improved usability and security. A graphical password system with a supportive sound signature increases the remembrance of the password. Here, user is asked to select a sound signature corresponding to click point. This sound signature will be used to help the user in recalling the click point on an image.
