- Abstract:
- Today there are many Internet sites which require only the entry by human users but unfortunately some computer softwares called bots are designed by some hackers to enter these sites and use their resources through false registration. As a result some systems named CAPTCHA have been introduced to tell apart human users and computer software. This paper introduces a new CAPTCHA method. In this method a simple mathematical problem is generated according to a predefined pattern but instead of some object's name, we put their images. Then the whole problem is saved and shown to the user inform of an image to be answered by him. But since answering this problem requires four abilities of understanding text of question, detection of question images, understanding the problem, and solving the problem, only a human user can answer this question and present computer programs are unable to solve it. This project has been implemented by PHP language. © 2007 IEEE
