PET 2003 was the 3rd Workshop on Privacy Enhancing Technologies. It all startedin2000withHannesFederrathorganizing"DesigningPrivacyEnhancing Technologies: Workshop on Design Issues in Anonymity and Unobservability," July 25-26, 2000, held at the Computer Science Institute (ICSI), Berkeley, CA (LNCS 2009). Roger Dingledine, Adam Shostack, and Paul Syverson continued in April 2002 in San Francisco (PET 2002, LNCS 2482). This year was Dresden, and as long as the new PET ?eld prospers, we intend to hold this workshop annually. The workshop focused on the design and realization of anonymity and an- censorship services for the Internet and other communication networks. Besides the excellent technical papers, we had four panels, led by Richard Clayton, - drei Serjantov, Marit Hansen, and Allan Friedman. This year we also extended our work-in-progress talk schedule, allowing 24 people from the audience to - troduce a variety of new technologies and perspectives. An event like PET 2003 cannot happen without the work and dedication of many individuals. First we thank the authors, who wrote and submitted 52 full papers.
