Abstract
CAPTCHA is an ultra-modern security approach in the world of internet. There is various form of CAPTCHA. This paper proposed another form of CAPTCHA called Image-based CAPTCHA. Image-based CAPTCHA is more securing as compare to other CAPTCHA (Text and Audio based CAPTCHA) techniques. Image-based CAPTCHA has been introduced to address the limitations of previous CAPTCHA methods. It is used to controlled mutilations are applied to haphazardly picked images and introduced to a client for an explanation from a given list of words. In this paper, we centre on how AI strategies perceive Image-based CAPTCHA. Additionally, we recall the image-based CAPTCHA. This paper proposed a strategy dependent on the Back Propagation algorithm to pinpoint the image-based CAPTCHA.
