This document proposes a Multi-facet Password Scheme (MAPS) for mobile authentication called Chess-based MAPS (CMAPS) that combines information from multiple facets (types of information) to generate passwords. CMAPS uses gestures on a chessboard interface to create passwords with a larger password space than 4-digit PINs or 8-character passwords, improving security. User studies showed CMAPS achieved high memorability while exceeding the security of standard passwords. The document reviews related work in graphical passwords, mobile authentication schemes, and gamification of security mechanisms. It also outlines threats assumed for the mobile authentication system, including a stolen device and an attacker unable to access data through other means.
