Compound Password System for Mobile

Authentication on mobile devices deviates from the traditional text-based password system. The choice to use alternative password systems comes at a cost and in this paper we explore the current issues with said systems and propose a new method for authentication on mobile devices. In this paper we explore the current landscape of mobile authentication. The mobile authentication systems, Personal Identification Number and Pattern passwords both have issues which makes them weak to attacks. Our goal is to create a scheme that can strengthen the security of mobile passwords by combining both methods of authentication. When a new security system is implemented there is two factors that determine the system's success, the complexity of the system and the usability or feasibility of the system. This paper looks to define the complexity of our scheme in terms of security.
