Captcha as Graphical password

Graphical password is an alternative scheme of alphanumeric password that is tedious process to recall the complex password. Psychological studies of human mind argue that recalling of images is easier than alphabets or digits. In this thesis, proposed recognition-based authentication built on Captcha technology. I propose method "Click-on-Captcha-Objects", which contains Captcha based visual objects (letters of any language, digits, and user-defined images), it helps to memorable of a strong password.
