Abstract: Pixel value graphical password scheme was designed in 2012 to simplify the user authentication process and reducing the implementation setup resource of graphical password authentication system. It was developed and tested in laboratory control environment using a camera captured photo. Through a dynamic analysis on password strength, accuracies output and usability study, pixel value graphical password scheme shows a promising result with huge potential to put into practice. In some cases, there are few limitations which need to be solved in order to implement the pixel value graphical authentication system and this study is aimed to find an alternative for password text length and size on storage disk. This paper is organised into five sections where the background of the pixel value graphical password scheme is described in the introduction section, followed by a discussion on the password style, brief description of hexadecimal code on following section, then the comparative discussion between eight bits code and hexadecimal code, and the conclusion section. The references are listed at the end of this paper.
