This book presents the proceedings of the 6th International Conference on Trust Privacy and
Security in Digital Business (TrustBus 2009) held in Linz Austria d- ing September 3 4 2009.
The conference continues from previous events held in Zaragoza (2004) Copenhagen (2005)
Krakow (2006) Regensburg (2007) and Turin (2008). The advances in the information and
communication technologies (ICT) have raised new opportunities for the implementation of novel
applications and the pro- sion of high-quality services over global networks. The aim is to
utilize this infor- tion society era for improving the quality of life for all citizens
disseminating knowledge strengthening social cohesion generating earnings and finally
ensuring that organizations and public bodies remain competitive in the global electronic m-
ketplace. Unfortunately such a rapid technological evolution cannot be problem free. Concerns
are raised regarding the lack of trust in electronic procedures and the - tent to which
information security and user privacy can be ensured. TrustBus 2009 brought together academic
researchers and industry developers who discussed the state of the art in technology for
establishing trust privacy and security in digital business. We thank the attendees for coming
to Linz to participate and debate the new emerging advances in this area.
