Privacy Enhancing Technologies: Second International Workshop, PET 2002, San Francisco, CA, USA, April 14-15, 2002, Revised Papers - Lecture Notes in Computer Science 2482 (Paperback)

The second Privacy Enhancing Technologies workshop (PET2002), held April 14-15, 2002 in San Francisco, California, continued the enthusiasm and quality of the ?rst workshop in July 2000 (then called "Designing Privacy Enhancing Technologies: Design Issues in Anonymity and Unobservability," LNCS 2009). The workshop focused on the design and realization of anonymity and an- censorship services for the Internet and other communication networks. For c- venienceitwasheldattheCathedralHillHoteljustpriortotheTwelfthConf- ence on Computers, Freedom, and Privacy (CFP2002), but it was not formally a?liated with that conference. There were 48 submissions of which we accepted 17. The program committee listed on the next page made the di?cult decisions on which papers to accept, with additional reviewing help from Oliver Berthold, Sebastian Clauss, Lorrie Cranor, Stefan K.. opsell, Heinrich Langos, Nick Mathewson, and Sandra Ste- brecher. Thanks to all who helped and apologies to anyone we have overlooked. Thanks also to everyone who contributed a submission. Besides the contributed papers we were honored to have an invited talk by someone who as much as anyone could be said to have started the entire technology ?eld of anonymity and privacy: David Chaum. The talk covered his recently developed voting technology based on visual secret sharing, and as if thatweren'tenough,alsodescribednewprimitivesforelectroniccash.Therewas also a lively rump session, covering a variety of new and upcoming technologies.
