An Enhanced Graphical Password Technique Using Fake Pointers

Abstract

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.
