Carleton University - School of Computer Science Undergraduate Honours Project Fall 2011 A security analysis of information leakage in graphical password discretization methods Weinan Liu 
ABSTRACT Graphical password systems play very important role in user authentication in last 12 years. In implementing click-based graphical password systems, Robust Discretization and Centered Discretization algorithms are proposed. However, the two discretization algorithms may leak information to attacker and help them to guess the correct password point on image. This paper designs and implements an experiment to test whether information will be leaked given the discretization grids over image. |
