Call for Papers
7th Workshop on Privacy Enhancing Technologies (PET '07)
University of Ottawa, Ottawa, Canada
June 20 - June 22, 2007

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. Approaches to protecting individuals, groups, but also
companies and governments from profiling and censorship include
decentralization, encryption, distributed trust, and automated policy

The 7th workshop on Privacy Enhancing Technologies addresses the
design and realization of such privacy 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 previous years, proceedings will be published 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
    * Privacy in Ubiquitous Computing Environments
    * 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

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 is strongly encouraged whenever
appropriate. Papers must conform to the Springer LNCS style. Follow
the "Information for Authors" link at this webpage.

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.

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, 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. Submitted papers should
be anonymized by removing or sanitizing author names, affiliations,
acknowledgments, and obvious self-references. 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

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. Click here for the 2004
version of this agreement.

Paper submissions must be received by February 23rd, 2007. We will
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 by April 23rd, 2007 and authors will
have the opportunity to revise for the preproceedings version due on
May 25th, 2007.

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.
