Abstract

This paper proposes a click based Graphical CAPTCHA to overcome the spyware attacks. In case of traditional Text-Based CAPTCHA's user normally enters disorder strings to form a CAPTCHA, the same is stored in the key loggers where spywares can decode it easily. To overcome this, Click-Based Graphical CAPTCHA uses a unique way of verification where user clicks on a sequence of images to form a CAPTCHA, and that sequence is stored in pixels with a random predefined order. Captcha as graphical passwords (CaRP) offers protection against online dictionary attacks on passwords, which have been for long time a major security threat for various online services. We are integrating the captcha technology with PCCP (called Persuasive cued click points) or Click based password system for higher security. It offers higher security when compared to the existing Captcha Technology. The password scheme in Graphical Captcha is highly secure and it’s better when compared to the existing technology.
