One of the most important topics in data protection or information security today is user authentication i.e. genuineness. The most common computer authentication or securing data is to use alphanumerical as the measure, using the text-based strong password schemes that often makes memorizing the password so difficult that makes the users writing them down on a piece of paper or saving inside the computer. The GUA (Graphical User Authentication) or simply graphical password has proposed an alternate scheme as an alternative to the text based schemes by the fact that humans tend to remember images better, as pictures are comparatively easier to be remembered or recognized.
