Extremely large scope in the field of designing CAPTCHA (completely automated public turing test to tell computers and humans apart)[1] are in demand these days. Various types of CAPTCHA tests have developed in order to address accessibility while implementing security. Our work is focused on creating novel genre CAPTCHA for enhanced security than existing one, against bot except human. For security purpose, we are creating and using different types of CAPTCHA. This paper endeavour to propose a solution to this ever-growing problem. PixCAPTCHA have designed for user dexterity and security. In this system, random pictures have displayed with the content of crop properties and instruction of how much pixels to be cropped. Then the user should crop the picture according to the given instruction and paste it in the space provided. This novel CAPTCHA is user friendly, but not for bot.
