Nowadays security matter is a great challenge in web-based systems and we are using various types of HIP to defend malwares in web.But today's conventional HIP models are able to defend bots but make a user ireful.This paper will focus on a new and simple model of CAPTCHA to defend bot-attack.This model makes a user easily to pass and also amuse them with its simplicity.Considering computational complexity, we are using a thin algorithm with some other technical tricks to make it both robust & simple.
