Graphical Password: Prototype Usability Survey

Abstract

Access to computer networks and systems is most often based on the use of conventional passwords nowadays. However, users have difficulty remembering a password that is long and random-appearing. So, they create short, simple, and insecure passwords. Graphical passwords have been designed to try to make passwords more memorable and easier for people to use, to create and, therefore, more usable and secure. Using a graphical password, users click on images rather than type conventional passwords. We have designed a usable graphical password system focusing in the usability features to the users, called Jetafida. In this paper we describe the Jetafida usability features, and the system usability features had been tested by questionnaire survey. This done by thirty computer students participates and uses the system for three times in different times to see the usability features achieved in the system. Where these features are ease of use, ease to create, ease to memorize, ease to learn and the overall system design and layout. The results show that the participants found that the proposed usable graphical password system has been achieving the usability features built in.
