The annual iTrust international conference looks at trust from multidis- plinary perspectives: economic, legal, psychology, philosophy, sociology as well as information technology, is built on the work of the iTrust working group (http://www.itrust.uoc.gr), and has had four highly successful conferences in Europe to date. The annual PST conference has quickly established itself as a leader in m- tidisciplinary research on a wide range of topics related to Privacy, Security and Trust, looked at from research and practice, through academe, business, and government. 2007 marks the 4th year of PST's existence. The two conferences come together in 2007 as the first annual meeting and conference of the newly formed IFIP Working Group on Trust Management (IFIP WGll.ll), a major step forward in Trust Management work globally. IFIPTM 2007 received 76 submission from 25 different countries: Canada (15), USA (10), United Kingdom (8), China (6), Finland, Italy (4), Korea, Switzerland, France, Ireland, Spain, Germany, Denmark, Jordan, Poland, Kuwait, Singapore, Iran, Netherlands, Japan, Luxembourg, Australia, Norway, Austria, Tunisia. The program committee selected 25 papers for presentation and inclu­ sion in the proceedings. In addition, the program and the proceedings include 4 short papers. This volume contains the proceedings of the IFIPTM 2007, the Joint iTrust and PST Conferences on Privacy, Trust Management and Security, held in Moncton, New Brunswick, Canada, in 2007. The annual iTrust international conference looks at trust from multidisciplinary perspectives: economic, legal, psychology, philosophy, sociology as well as information technology. This volume, therefore, presents the most up-to-date research on privacy, security, and trust management.
