In recent years, graphical passwords have been proposed as a potential authentication solution due to their improved usability features and the superior human ability to recognize and remember images. In this paper we propose new recognition-based graphical authentication mechanisms called ImagePass, suitable for ubiquitous environments and touch based interfaces. The authentication mechanism introduces a novel feature based on one-time words that increases the security of the system without compromising its usability. Regarding usability, we explore the users' perception of the graphical mechanisms, and investigate a number of issues, such as memorability.
