Abstract
The aim of this paper is to present conceptual foundations for an ongoing comprehensive study on the effects of Mental Model and culture on the selection and the design of the Recognition-Based Graphical Password (RBG-P). A flexible Security, Usability, Mental (SUM) meta-model has been proposed to provide better insights on designing a usable RBG-P through manipulating the optimal equilibrium solution expanse (δ) without compromising security. This manipulation results in the design requirements, which is a consequence of the combinative effects of both the user and the designer mental models as constituted by the culture. A cognitive map has been produced to explicate the relationship between constituents of usability and security provided by the RBG-P. The development of the mental model process necessitates the building of new mindset and culture. This multifaceted relationship of the Shared Mental Model (SMM) development is represented by extrapolating of Metcalfe’s law to social networks.
