摘要：Most of the computer systems use password as a method of choice for authenticating users. Text is generally is used for such authentication, but these textbased passwords are insecure.To provide a better security for user authentication Captcha (Completely Automated Public Turing tests to tell Computers and Humans Apart) as graphical passwords are used. Graphical passwords use images or representation of images as password. The human brain easily remembers the ‘Graphical image secret word’ when compared to the ‘Text secret word’. Nowadays, in market, many graphical image secret word software’s are available, as well as distinct graphical image secret word methods. The work proposed in this paper, merges Cued click points with token based verification and Captcha text. Prime intention of this proposal is to minimize the guessing attacks as well as to encourage users to select morerandom and difficulttoguess passwords.
