CAPTCHA is a standard security technology for distinguish between human and computer program automatically which stands for Completely Automated Public Turing test to tell Computers and Human Apart. CAPTCHA has been widely used for preventing malicious programs to access web resources automatically. The basic idea of CAPTCHA is providing questions that human users can easily recognize and answer but computer programs cannot. With the rapid development of AI and image recognition, simple CAPTCHA is facing the problem of being cracked, while complicated CAPTCHA is difficult for the humans to recognize. In this paper, we propose a new CAPTCHA implementation mechanism based on handwritten 3D Animated CAPTCHA and based on the weak point of computer vision.
