Abstract: In recent years, the access to computer networks and systems is mostly based on the use of conventional passwords. As the number of online internet services (requiring authentication) is increasing rapidly, the number of needed passwords is also increasing. The result is the load on user’s memory to remember such increasing number of passwords that makes them to create short, simple and insecure passwords. This has a possible security risk on user’s privacy. Graphical passwords have been designed to make passwords more memorable and easier; humans are more adepted at remembering images.In this paper an experimental image-based authentication system has been developed by users through authentication to online purchasing websites. This system relies on user’s ability to recognize a previously seen image. A userquestionnaire has been developed before presenting the system to the users. The system has been tested in a 2-week experiment on nearly 33 MSc students in university of Portsmouth and library staff. After collecting the results, the analysis shows that the majority of the users were interested in using image-based authentication system. The project finding illustrates some results that shows the importance of the study of image-based authentication systems. For instance, the majority of users who succeeded in authenticating through using the system have created a story by using the images. This finding could define the image-based authentication as a common practical usage.
