Abstract
In this paper we have introduced a new form of captcha named CLAPTCHA. This Claptcha we believe can reform a new world of image and imagination based captcha. In this Claptcha, we have to find the English alphabets (alpha). Its efficiency is also proven here to be better than normal image based captchas or imagination captchas. Claptchas will be also more user friendly and enjoying.
