Korey Johnson to give presentation at HFES 2008

Korey Johnson (User Centric) will present a paper written by himself and co-author, Steffen Werner (University of Idaho) on the usability of user authentication mechanisms at the 52nd Annual Meeting of the Human Factors and Ergonomics Society (HFES). Previous studies (Johnson & Werner, 2006; 2007) have shown that Composite Scene Authentication (CSA) passcodes are more memorable than alphanumeric passwords over extended retention intervals. This study evaluated the memorability of six types of graphical passcodes of varying complexity (including three variants of CSA passcodes) over thirty-minute and one-week retention intervals
