Recognition-Based Graphical Authentication with Single-Object Images

Abstract

Getting users to abandon text-based passwords has been a rather difficult task. Several alternatives to textual passwords have been proposed including authentication based on images. Research shows that graphical authentication mechanisms have some advantages, but they lack the necessary qualities to move them from isolated to mass market environments. This paper builds on current research and previous papers and presents the second iteration of ImagePass, a novel graphical authentication mechanism that follows usable security guidelines. Based on ambitious usability tests this approach has been demonstrated as a feasible authentication alternative for desktop and mobile environments.
