Security Implementation of 3-Level Security System Using Image Based Authentication
Now-a-days, as information systems are more open to the Internet, the importance of security for networks is tremendously increased. Usable security has unique usability challenges because the need for security often means that standard human-computer-interaction approaches cannot be directly applied. An important usability goal for authentication systems is to support users in selecting better passwords. Users often create memorable passwords that are easy for attackers to guess, but strong system-assigned passwords are difficult for users to remember. So researchers of modern days have gone for alternative methods. Here a graphical password system with One-Time Password (OTP) is discussed. In proposed work a click-based graphical password scheme called Persuasive Cued Click Points (PCCP) is presented.
