Abstract

In order to distinguish between human users and computer programs, CAPTCHA (completely automated public turing test to tell computers and human apart) mechanism is widely applied in Web sites such as accounts application Web site. While the major implementation of CAPTCHA method-2D still image verification code based on OCR technology is threatened by developing artificial intelligence and image recognition technologies. In this paper, we propose a new approach to implement CAPTCHA mechanism based on 3D animation, utilizing the weakness of computer vision, which make it robust to computer attacks and convenient for users to recognize, and implemented this method to generate a 3D animation verification code.
