This book contains the proceedings of the 5th International Conference on Trust,
Privacy and Security in Digital Business (TrustBus 2008), held in Turin, Italy on 4–5
September 2008. Previous events in the TrustBus series were held in Zaragoza, Spain
(2004), Copenhagen, Denmark (2005), Krakow, Poland (2006), and Regensburg,
Germany (2007). TrustBus 2008 brought together academic researchers and industrial
developers to discuss the state of the art in technology for establishing trust, privacy
and security in digital business. We thank the attendees for coming to Turin to partici-
pate and debate upon the latest advances in this area.
