Abstract

In some Websites it is necessary to distinguish between human users and computer programs which is known as CAPTCHA (completely automated public turing test to tell computers and human apart). CAPTCHA methods are mainly based on the weaknesses of OCR systems while using them are undesirable to human users. In this paper a new CAPTCHA method is introduced on the basis of showing a movie of a personpsilas action. Then we ask the user to describe the movement of that person. The user should select the sentence which describes the motion from a list of sentences. If the user chooses the right sentence we can guess that the user is a human and not a computer program. The main advantage of this method is its simplicity and also the difficulty of computer attacks to it. This project has been implemented by PHP scripting language.
