Workshop on Privacy Enhancing Technologies

Dubrovnik (Cavtat), Croatia         30 May - 1 June 2005


Call for Papers:   5th Workshop on Privacy Enhancing Technologies 

Privacy and anonymity are increasingly important in the online world. Corporations, governments, and other organizations are realizing and exploiting their power to track users and their behavior, and restrict the ability to publish or retrieve documents. Approaches to protecting individuals, groups, but also companies and governments from such profiling and censorship include decentralization, encryption, distributed trust, and automated policy disclosure.

This 5th workshop addresses the design and realization of such privacy and anti-censorship services for the Internet and other communication networks by bringing together anonymity and privacy experts from around the world to discuss recent advances and new perspectives.

The workshop seeks submissions from academia and industry presenting novel research on all theoretical and practical aspects of privacy technologies, as well as experimental studies of fielded systems. We encourage submissions from other communities such as law and business that present their perspectives on technological issues. As in past years, we will publish proceedings after the workshop in the Springer Lecture Notes in Computer Science series.

Suggested topics include but are not restricted to:

* Anonymous communications and publishing systems
* Censorship resistance
* Pseudonyms, identity management, linkability, and reputation
* Data protection technologies
* Location privacy
* Policy, law, and human rights relating to privacy
* Privacy and anonymity in peer-to-peer architectures
* Economics of privacy
* Fielded systems and techniques for enhancing privacy in existing systems
* Protocols that preserve anonymity/privacy
* Privacy-enhanced access control or authentication/certification
* Privacy threat models
* Models for anonymity and unobservability
* Attacks on anonymity systems
* Traffic analysis
* Profiling and data mining
* Privacy vulnerabilities and their impact on phishing and identity theft
* Deployment models for privacy infrastructures
* Novel relations of payment mechanisms and anonymity
* Usability issues and user interfaces for PETs
* Reliability, robustness and abuse prevention in privacy systems

Stipends to attend the workshop will be made available, on the basis of need, to cover travel expenses, hotel, or conference fees. You do not need to submit a technical paper and you do not need to be a student to apply for a stipend. For more information, see the stipends page.

Papers should be at most 15 pages excluding the bibliography and well-marked appendices (using an 11-point font), and at most 20 pages total. Submission of shorter papers (from around 4 pages) is strongly encouraged whenever appropriate. Papers must conform to the Springer LNCS style. Follow the "Information for Authors" link at

Reviewers of submitted papers are not required to read the appendices and the paper should be intelligible without them. The paper should start with the title, names of authors and an abstract. The introduction should give some background and summarize the contributions of the paper at a level appropriate for a non-specialist reader. A preliminary version of the proceedings will be made available to workshop participants. Final versions are not due until after the workshop, giving the authors the opportunity to revise their papers based on discussions during the meeting.

Submit your papers in Postscript or PDF format. To submit a paper, compose a plain text email to containing the title and abstract of the paper, the authors' names, email and postal addresses, phone and fax numbers, and identification of the contact author (to whom we will address all subsequent correspondence). Attach your submission to this email and send it. By submitting a paper, you agree that if it is accepted, you will sign a paper distribution agreement allowing for publication, and also that an author of the paper will register for the workshop and present the paper there. Our current working agreement with Springer is that authors will retain copyright on their own works while assigning an exclusive 3-year distribution license to Springer. Authors may still post their papers on their own Web sites. For a preview of the 2005 agreement, see the 2004 version of the paper distribution agreement.

Submitted papers must not substantially overlap with papers that have been published or that are simultaneously submitted to a journal or a conference with proceedings.

Paper submissions must be received by February 7. We acknowledge all submissions manually by email. If you do not receive an acknowledgment within a few days (or one day, if you are submitting right at the deadline), then contact the program committee chairs directly to resolve the problem. Notification of acceptance or rejection will be sent to authors no later than April 4 and authors will have the opportunity to revise for the preproceedings version by May 6.

We also invite proposals of up to 2 pages for panel discussions or other relevant presentations. In your proposal, (1) describe the nature of the presentation and why it is appropriate to the workshop, (2) suggest a duration for the presentation (ideally between 45 and 90 minutes), (3) give brief descriptions of the presenters, and (4) indicate which presenters have confirmed their availability for the presentation if it is scheduled. Otherwise, submit your proposal by email as described above, including the designation of a contact author. The program committee will consider presentation proposals along with other workshop events, and will respond by the paper decision date with an indication of its interest in scheduling the event. The proceedings will contain 1-page abstracts of the presentations that take place at the workshop. Each contact author for an accepted panel proposal must prepare and submit this abstract in the Springer LNCS style by the "Camera-ready copy for preproceedings" deadline date.
