Abstract

Recent research reveals interaction effects among human cognitive processing factors, interaction device types and user authentication schemes towards security of user created graphical keys. Aiming to investigate how different visual behaviors of individuals with varying cognitive strategies affect the security aspects of graphical user authentication (GUA) across device types, this paper reports preliminary results of a user study (N=51) on graphical password composition using a recognition-based GUA scheme. Results reveal differences on key strength and complexity, as well as on gaze-based entropies between users with different cognitive strategies, which can be used for the design of user-adaptive GUA schemes.
