Currently, access to computer systems is often based on the use of alpha-numeric. The textual passwords or alpha-numeric passwords have been the basis of authentication systems for centuries. Similarly, it had also been the major attraction for crackers and attackers. However, users tend to face difficulty in remembering a password that is considered as secured password because this type of secured password usually has long string of characters and they appear randomly. Hence, most users tend to create simple, short and insecure passwords. As a consequence, most of the time, the usability level of passwords has not achieved an optimum for a secured password. In order to solve this problem, a new password scheme had been invented, known as Graphical Password System (GPS).
