摘要：since the evolution of Internet, web security has become a primary concern and is also very challenging with its day by day growth. Our aim is to utilize CAPTCHAs as a system to improve the security for Internet based applications. There are many threats circulating on the Internet and one such threat is BOT, a malicious program, which runs automated tasks over the Internet and thus creates problem. As a shield to this problem we make use of CAPTCHA. The main idea behind this research is to provide a better methodology implementing the web security. We will try to develop the technique which will use the transparent image based CAPTCHA. Along with this we will also use the filters to increase the complexity in identifying the images. This will help in preventing the attacks from the Internet like BOT etc. The transparent images based CAPTCHA system makes exploitation a very difficult thing for BOT, but it is easier for a human being to interpret it.
