Shoulder Surfing Resistant Graphical Authentication Scheme for Web Based Applications

Since the design and development of the first graphical authentication pioneered by Blonder in 1996, numerous research has been conducted on this area to be used in different scenario especially on the Internet. One of the major motivators is the picture superiority which as studies have shown, states that image/pictures provides higher memorability as opposed to Text based authentication. However, graphical authentication is still faced with some challenges. In this paper, a shoulder surfing resistant graphical authentication scheme is proposed to tackle the major issues related to the graphical authentication schemes developed. In summary, the proposed scheme provides a high level of resistance to shoulder surfing attacks, mitigating the need to upload pictures and aids in finding chosen objects in the scheme. Finally, the schemes still have some vulnerabilities thus, concluding that there cannot be a perfect graphical authentication scheme; each scheme has its merits and demerits making it a suitable candidate for different environment and/or event based on its architecture.
