Study and develop a new graphical password system

Abstract

Graphical password have been proposed as a possible alternative solution to text-based password, motivated particularly by the fact that humans can remember pictures better than text. The main aim of this project is to study the usability features of the recognition base graphical password methods regarding to general usability features and ISO standard usability features then a comparison study between the usability features and sub features of these methods has been done and finally map all that features and sub features to the existing graphical password methods to get the new usability features can be implemented in the new usable graphical password prototype. A graphical password system framework has been built and divided into two stages, new user and existing user stage, then the system implemented as prototype and an evaluation of the prototype usability features has been conducted by questionnaire survey in the UTM (CASE) and Computer Science Faculty students (Johor), then the user's feedback about the whole system and the usability features of the graphical password prototype results collected and analyzed and all the results percentages are very good which mean that the new graphical password system is acceptable from the usability point view..
