A Gamified Approach to Improve Users' Memorability of Fall-back Authentication
英文摘要：
Security questions are one of the techniques used in fall-back authentication to retrieve forgotten passwords. This paper proposes a game design which aims to improve usability of system-generated security questions. In our game design, we adapted the popular picture-based "4 Pics 1 word" mobile game. This game asks users to pick the word that relates the given pictures. We selected this game because of its use of pictures and cues, in which, psychology research has found to be important to help with memorability. The proposed game design focuses on encoding information to users' long- term memory and to aide memorability by using the follow- ing memory retrieval skills: (a) graphical cues - by using images in each challenge; (b) verbal cues - by using verbal descriptions as hints; (c) spatial cues - by keeping same or- der of pictures; (d) interactivity - engaging nature of the game through the use of persuasive technology principles.
