Abstract
In an increasingly mobile world, the combination of mobile computing devices, publicly accessible Wi-Fi hotspots, and camera phones pose a significant threat to alphanumeric passwords in public environments. Graphical passwords, introduced as an alternative to alphanumerical passwords, help prevent successful shoulder-surfing attacks – covertly observing or recording a password login session, however, most cannot prevent intersection analysis on the data collected through shoulder-surfing. ColorDots is a new graphical password scheme designed to be easy to use and learn, to prevent successful shoulder-surfing attacks, and to hinder intersection analysis. A software implementation of ColorDots is tested, and the results analyzed. This study showed the ColorDots graphical password scheme does prevent shoulder-surfing, and hinders intersection analysis on digital recordings of multiple shoulder-surfing attacks. Furthermore, ColorDots may be just as convenient to use as alphanumeric passwords, while improving password security in public environments.
