Description

Graph Theory Is a Branch of Discrete Mathematics. In Mathematics and Computer Science, Graph Theory is the Study of Graphs which is mathematical structures used to model pair wise relations between objects. There is wide use Of Graphs in providing Problem solving Techniques in various field of computer science, because it gives an intuitive manner prior to solve and present different results. Today all of us want to keep data online for smooth functioning of the various demands of an enterprise. So, data security in one is great challenge in front of the entire researcher. So, Graph theory plays a major role to make data secure and authenticate. The proposed algorithm is used to secure data using cryptography. Cryptography is a method with the help of which we can make data unreadable, but unreadable data only intended to read by the receiver. We have proposed many methods of keeping data save from malicious users. But we are using graph theory to make data secure and not easily accessible by anyone. Its aims to enhance authorization and authentication process by using multilevel authentication, to implement various security measure to protect data. Also user can change access control by using innovative method in every transaction at any instance of time according to individual user requirement and condition. In this book we provide a simple yet powerful method of how an unremarkable change to a graphical password interface can modify the distribution of user chosen passwords, and which is also simple and suitable of providing and transferring passwords.
