Encoding passwords using QR image for authentication

Today, the world is moving beyond the imagination of the people, day by day new era in technology comes which create huge impact on their lives. As the invention of the computer takes place, now most of the work is performed with the help of computer. In order to protect the main resource of the people, it is important to make the modification in older technology or create a new one. Level of security such as textual password, biometric etc. are imposed. But there is some disadvantage i.e. textual password is easy to remember. On the other hand by using graphical approach, we can give the best alternative to the passwords as done in this paper. We presented a system based on the graphical scheme that uses QR code and the basic methodology is inside the levels of encryption in QR code. Our aim is to give the more complexity to the high yielding encryption in graphical passwords.
