Social Navigation as a Model for Usable Security

Student: Paul DiGioia, UCI/ISR

Advisor: Paul Dourish, UCI/ISR

Abstract: As interest in usable security spreads, the use of visual approaches in which the functioning of a distributed system is made visually available to end users is an approach that a number of researchers have examined. In this poster, we discuss the use of the social navigation paradigm as a way of organizing visual displays of system action. Drawing on a previous study of security in the KaZaa peer to peer system, we present some examples of the ways in which social navigation can be incorporated in support of usable security.

Bio: Paul DiGioia is an undergraduate student in the Donald Bren School of Information and Computer Sciences at the University of California, Irvine. He will obtain his Bachelor of Science in Information & Computer Science in June, 2005, and will begin work on his Master of Science also from UCI beginning Fall, 2005. Paul's research interests include computer & network security technologies, human-computer interaction, and usable security.
