Testing design for pixel value graphical password scheme on image specimens

Abstract

In decades, authentication system is relying on username and password as pass-phrase object for authentication process. The longer, wider the variety of symbol choices, and randomly arranged phrase considered as a strong password. A strong password is hard to memorize and make it less preferred by most of the users in most of the cases. To make pixel value graphical password scheme a test-able subject, a coded prototype was developed and deployed. The coded prototype was called as Pixel Value Access Control (PVAC). The study is focused on the testing design and result of experimental testing on different scenario using 24 specimens are used to test the functionality of PVAC pixel value extraction process to produce an accurate pixel value.
