Trust and Privacy in Digital Business

Sincerely welcome to proceedings of the 1st International Conference on Trust and Privacy in Digital Business, Zaragoza, Spain, held from August 30th to September 1st, 2004. This conference was an outgrowth of the two successful TrustBus inter- tional workshops, held in 2002 and 2003 in conjunction with the DEXA conferences in Aix-en-Provence and in Prague. Being the first of a planned series of successful conferences it was our goal that this event would initiate 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 and privacy in digital business. We thank you all the attendees for coming to Zaragoza to participate and debate the new emerging advances in this area. The conference program consisted of one invited talk and nine regular technical papers sessions. The invited talk and keynote speech was delivered by Ahmed Patel from the Computer Networks and Distributed Systems Research Group, University College Dublin, Ireland on Developing Secure, Trusted and Auditable Services for E-Business: An Autonomic Computing Approach. A paper covering his talk is also contained in this book. The regular paper sessions covered a broad range of topics, from access control - sues to electronic voting, from trust and protocols to digital rights management. The conference attracted close to 100 submissions of which the program committee - cepted 29 papers for presentation and inclusion in the conference proceedings.
