Abstract
The main function of CAPCHA is to prevent malicious programs from register or login, malicious irrigation, bag breaking and other network attacks. Most of the current graphic CAPTCHA’s are generated based on numbers or letters by using a random function and then perform distortion or add viscosity curves. These graphic CAPTCHA’s can easily be identified by user, but provides an opportunity for malicious software attack website system. This paper puts forward an algorithm based on multiple layers to generate random Chinese character CAPTCHA’s which has a variety of deformation features. We apply it to dynamic webpage, to ensure the security of land check.
