Safe and Secure Graphical Authentication System

Authentication is one of the main aspect in the computer applications, to grant access to particular individual authentication is the process to do that. Lots of research has been done in the development of such authentication scheme, which are simple in users perspective and is secure in attackers perspective. Early days of computers belong to the authentication which is based on the text passwords, text-based passwords are the most commonly used authentication scheme in the world. Now a days text-based passwords are way too much popular for authentication. On the other hand with the development of handheld devices Graphical Passwords got more attention in the authentication process. The reason behind development of graphical passwords is, they are easy to remember as compared to the text-based passwords. Everything on the internet needs authentication in the way of providing services to the user, so it is important to make sure that the security issues related to the authentication must have been solved by the authentication system. In this way to develop the authentication scheme which is easy to understand and difficult to crack, this research paper is all about. This paper focuses on the research done in the field of graphical passwords and finally we propose a graphical authentication system based on some previous work done. In this paper we are going to see how we can add more security to the authentication process by using the homomorphic encryption in the database.
