Authentication Technique

Security is the degree of resistance to, or protection from harm. It applies to any vulnerable and valuable asset, such as person, community, nation, or organization. Thus, the determination of a user being allowed access to a resource(s) is done cautiously. Alphanumeric password has been used for authentication, however, it is inherently limited. Graphical password is a possible alternative. Consequently, this paper designs a new graphical password technique based on images, rather than alphanumeric strings. Although, graphical password technique is more secure than textual password. It is also vulnerable to attacks. The most common problem therefore with Graphical Password is the Shoulder Surfing problem, also called “PEEPING ATTACK”. In this paper, we proposed a user authentication technique called “FAKEPOINTER”- a user authentication technique that conceals users’ authentication secret regardless of a shoulder surfer success by video camera(s). In the software designed, a graphical password fake indicator (pointer) is incorporated to enhance users’ login (password) against attack. The system is designed to run on windows platform with .Net support with Microsoft Structured Query Language Server as the back end, C# as front end. The system performs better when compared to existing system.

The usage and management of information technology resources and services are revolutionized with the arrival of Cloud Computing. But, the revolution always comes with problems. Authentication is one such problem. Especially for Graphical Password Authentication System, there is a threat of shoulder surfing attack. This research presents a multi-level graphical password authentication mechanism by extending an existing method. UGPSCCCT (User guided Graphical Password Scheme for Cloud using Caesar Cipher Technique) is the existing method and this method is extended in this paper such that another level of security is added. The user credentials in this method are transmitted to the server in encryption format. A key is generated for every login to encrypt user details. The analysis of the proposed method is done by calculating the computational cost and communication cost of the proposed method
