Graphical Password Authentication

Abstract: We propose and examine the usability and security of Cued Click Point (CCP), a cued-recall graphical password technique. Users click on one point per image for a sequence of images. The next images are based on the previous click point. We present the result of an initial user study which revealed positive results. Therefore graphical password has been proposed by many researchers as an alternative to text based password Graphical passwords can be applied to workstation, web log-in applications, ATM machines, mobile devices etc. This paper presents implementation of Cued click point (CCP) graphical password which uses circular tolerance. Then it is found that CCP with circular tolerance is better as compared to CCP with rectangular tolerance. Key words: CCP, Secret click, Graphical password.
