Sincerely welcome to the proceedings of the 2nd International Conference on Trust, Privacy, would be and Security in Digital Business, held in Copenhagen, Denmark, from August 22nd till 26th, 2005. This conference was the successor to the successful TrustBus 2004 conference, held in 2004 in conjunction with the DEXA conferences in Zaragoza. It was our goal that this event would be a forum to bring together researchers from academia and commercial developers from industry to discuss the state of the art of technology for establishing trust, privacy, and security in digital business. We thank the attendees for coming to Copenhagen to participate and debate the new emerging advances in this area. The workshop program consisted of one invited talk and 11 regular technical paper sessions. The invited talk and keynote speech was delivered by Hannes Federrath from the Chair for Management of Information Security at the University of Regensburg, Germany, on “Privacy Enhanced Technology, Methods – Markets – Misuse”. A paper covering his talk is also contained in this book. The regular paper sessions covered a broad range of topics, from access control issues to electronic auctioning, from trust and protocols to smart cards. The conference attracted over 100 submissions of which the Program Committee accepted 32 papers for presentation and inclusion in the conference proceedings. The authors of the accepted papers come from 16 different countries. The proceedings contain the revised versions of all accepted papers.
