摘要：Today, internet has become a global tool for accessing services whether it is education, entertainment or e-commerce. In order to register on these sites, a distorted image of pseudorandom letters and digits is to be entered at the end of the form in order to gain access to the service. That distorted image is called Captcha(Completely Automated Public Turing Test To Tell Computers And Humans Apart).In this paper we are presenting a technique of the combination of noise and color in Captcha which will make it more human friendly and difficult for automated programs to break the Captcha.
