Identifying the Re-usability of Triangle Scheme and Intersection Scheme on Mobile Device

Lim Kah Seng, Norafida Ithnin, Hazinah Kutty Mammi


Graphical passwords are vulnerable to shoulder surfing attacks as the images are easier to remember than the text. Thus, existing graphical password schemes incorporate an anti-shoulder surfing mechanism, to ensure the graphical password is secure from shoulder surfing attacks. Unfortunately, the literature review has shown that most of the graphical password schemes that have anti-shoulder surfing mechanisms are general device graphical password schemes, not mobile device graphical password schemes.  Therefore, in this experiment, two general device graphical password anti-shoulder surfing mechanisms, which are the Triangle Scheme and the Intersection Scheme, are reconstructed on a mobile device to test whether or not the general device graphical password anti-shoulder surfing mechanism is suitable for re-use in mobile devices.
