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 51st Annual Meeting of the Human Factors and Ergonomics Society (HFES). Issues that arise when using alphanumeric passwords will be discussed and empirical support will be provided for Composite Scene Authentication (CSA), the authors' novel method of authenticating users. The memorability of both alphanumeric and CSA passcodes will be examined at retention intervals as long as 6 weeks.
Korey has a strong interest in user interface design and user research, and has a background in research methods and usability. He received a B.A. in Psychology from Lewis and Clark college in Portland, OR and a M.S. in Human Factors Psychology from the University of Idaho. Korey is the co-inventor of a patent-pending graphical passcode technology that was the focus of his M.S. thesis research on usability of user authentication mechanisms. He also brings experience from the surface transportation industry.
