Pixel Value Graphical Password Scheme: Identifying Design Features and Requirements

Abstract

Pixel value graphical password scheme was introduced with the aim to solve problems faced by users during authentication process that arising from current graphical password scheme weaknesses. Even though the idea of graphical password scheme is still under analysis stage, many researchers have come out with a lot of vulnerabilities finding for current graphical password scheme. Literature studies on vulnerabilities finding has contributed for a development of method design features and requirements for pixel value graphical password scheme. This paper is organized as begin with a brief introduction on graphical password scheme, followed by literature study outcome, discussion on features and requirements, and enclosed with topic conclusion.
