CAPTCHA system based on puzzle is developed by using a technique based on an image CAPTCHA. Then, this type of CAPTCHA had developed by using HTML, JavaScript / JQuery and Cascading Style Sheets (CSS). The CAPTCHA system is developed using a sequence of phases of development that are in the methodology of evolutionary prototyping model. Applications certification is expected a confirmatory test that is easily solved by the user and then be interactive authentication applications.
