Call for Participation
June 15-19, 2009, Purdue University, West Lafayette, USA.

The mission of the IFIPTM 2009 conference is to share research solutions to problems of Trust and Trust management, including related Security and Privacy issues, and to identify new issues and directions for future research and development work. Building on the traditions inherited from the highly successful iTrust conference series, the IFIPTM 2007 conference in Moncton, New Brunswick, Canada, and the IFIPTM 2008 conference in Trondheim, Norway, IFIPTM 2009 focuses on trust, privacy and security from multidisciplinary perspectives. The conference will be an arena for discussion about relevant problems from both research and practice in the areas of academia, business, and government.


The IFIPTM 2009 conference has four pre-conference workshops on June 15 and 16:

· Sustaining Privacy in Autonomous Collaborative Environments (SPACE)
· Social Trust’09
· Joint International Workshop on Context-Aware Trust and WEB 2.0 TRUST (CAT09 2.0)
· The First International Workshop on Managing Insider Security Threats (MIST 2009)

In addition, there will be a tutorial on Online Trust and Reputation Systems, given by Prof. Audun Josang.

The main conference program features three Keynote talks given by Prof. Marianne Winslett (UIUC), Dr. Michael Novak (USAF AFRL/RYT), Prof. Eugene Spafford (Purdue); 17 regular paper presentations, and demonstrations.
