Abstract

With growing use of internet and its services, a large number of organizations are making use of password to provide security. A password is a secret word or combination of alphabet used for user authentication. Authentication to user account to access internet services on-line is achieved victimization password. The password is most convenient means of authentication. But now a day’s password becomes hacked by the attacker. To provide more security, we are using Kerberos and the video CAPTCHA as authentication technique. Kerberos is an authentication protocol and CAPTCHA is a (Completely Automated Public Turing Test to tell Computer and Human Apart) test which provide a way to differentiate user into a human and malicious program. CAPTCHA become the most widely used standard security technique to prevent automated computer program attack. Our aim is to proposed a system which can be a better than existing CAPTCHA and provide higher level of authentication.

Keywords: CAPTCHA, Video CAPTCHA.
