Abstract: “Graphical password scheme is perhaps the most widely used method to lock the mobile handsets but unfortunately they are easily guessable. In this paper, we have identified the security threat that the graphical password patterns in smart phones are predictable based on various important parameters like demographics, language proficiency, cultural backgrounds, etc. We further proposed a framework, which suggests you the most non-predictable and secure password pattern considering the demographics, language proficiency, and cultural backgrounds of the user.”

Keywords: Security threats, Predictable passwords, Graphical password patterns, demographics, cultural background, language proficiency, secure passwords.
