With an adding number of automated software bots and automated programs that abuse and loose public web services, the user is primarily needed to go through and break a Turing test problem, before they're allowed to use web operations and web services. This Turing test is nominated as CAPTCHA (Completely Automated Public Turing test to distinguish Computers and Humans Apart). CAPTCHA is an acronym of the Completely Automated Public Turing test to distinguish Computers and Humans Apart. CAPTCHA is a fashion of testing which ensures that only those people just passing the test and not the system computer generated (bots) are allowed to proceed further. The development of CAPTCHA system is to furnish creative and confirmation tests that can be fluently answered by humans and delicate for bots.[1] CAPTCHA system based on puzzle is developed with the help of an image CAPTCHA. This type of CAPTCHA had developed by using HTML, JavaScript/ JQuery and Cascading Style Sheet (CSS). The CAPTCHA system is developed using a sequence of phases of development that are in the methodology of Waterfall Method.
