An Analysis of Numerical Grid-Based Authentication

Passwords have been used as an authentication method for a long time. Many variations have also been proposed and applied. Grid-based passwords are also ones that have caught up with others in popularity. This paper analyses the security of such system. How the way that users select cell positions in different grid sizes affect overall security of the system is investigated. How they think of the ease of use of each of the grid sizes is also studied. As a result, an attempt is then made to find a balance between security and usability.
