Design and Implementation of an Optimized Way of Multi-Phase Grid and Color Based Password Authentication System in Cloud Computing
Human being can remember graphical notations & signs, very easily & for a long time. This paper is to build a mechanism for password so that the users’ password become more secure, remembering durability & easy to create. The authors have implemented for multi-tier authentication system, because multi-tier authentication system is more secure than single level authentication system. They are using graphical symbols as password, so that user can remember multiple passwords for a long time. Obviously, if they are giving more facility to the user then they must more concern towards the security of the passwords. This is a mechanism to optimize between facilities & securities.
