Abstract :
This paper describes the technical details of designing and implementing a simple anti breaking CAPTCHA system for ordinary MIS, including the layout of the characters, forming of CAPTCHA image, designing of corresponding cookies, etc. By the clever layout and twisting manipulation, its anti breaking strength is enhanced greatly. The system is designed in C and does not need the support of any dedicated graphics library. Therefore it can be not only suitable for ordinary MIS but also embedded application systems.
