Evaluation of Eye-Gaze Interaction Methods for Security Enhanced PIN-Entry In OzCHI '07: Proceedings of the 19th Australasian Conference on Computer-Human interaction: Entertaining User interfaces. Adelaide, Australia, November 28 - 30, 2007. ACM, New York, NY, 199-202. DOI= http://doi.acm.org/10.1145/1324892.1324932, ISBN 978-1-59593-872-5. (bib) |
Personal identification numbers (PINs) are one of the most common ways of electronic authentication these days and used in a wide variety of applications, especially in ATMs (cash machines). A non-marginal amount of tricks are used by criminals to spy on these numbers to gain access to the owners valuables. Simply looking over the victims shoulders to get in possession of their PINs is a common one. This effortless but effective trick is known as shoulder surfing. Thus, a less observable PIN entry method is desirable. In this work, we evaluate three different eye gaze interaction methods for PIN-entry, all resistant against these common attacks and thus providing enhanced security. Besides the classical eye input methods we also investigate a new approach of gaze gestures and compare it to the well known classical gaze-interactions. The evaluation considers both security and usability aspects. Finally we discuss possible enhancements for gaze gestures towards pattern based identification instead of number sequences. |
