A study of graphical password for mobile devices

Abstract

The objective of this project is to conduct a comprehensive research into the usability; design and security of graphical password on touch screen devices. We address the design limitation of touch screen devices and possible solutions. We also propose a simple graphical password scheme designed specifically for touch screen devices. Further, expert reviews and usability studies were used to explore user interactions in order to gain a more complete understanding on the potentials to improve the graphical password design for touch screen mobile devices.
