Call for Papers

15th Privacy Enhancing Technologies Symposium (PETS 2015)
Drexel University, Philadelphia, PA, USA
June 30 – July 2, 2015

The annual Privacy Enhancing Technologies Symposium (PETS) brings together privacy and anonymity experts from around the world to discuss recent advances and new perspectives. PETS addresses the design and realization of privacy services for the Internet and other data systems and communication networks.

PETS seeks paper and panel submissions for its 15th event to be held in Drexel University, Philadelphia, PA, USA on June 30 – July 2, 2015. Papers should present novel practical and/or theoretical research into the design, analysis, experimentation, or fielding of privacy-enhancing technologies. While PETS has traditionally been home to research on anonymity systems and privacy-oriented cryptography, we strongly encourage submissions in a number of both well-established and some emerging privacy-related topics.

New starting this year: Papers will undergo a journal-style reviewing process and be published in the Proceedings on Privacy Enhancing Technologies (PoPETs). PoPETs, a scholarly journal for timely research papers on privacy, has been established as a way to improve reviewing and publication quality while retaining the highly successful PETS community event. PoPETs will be published by De Gruyter Open, the world's second largest publisher of Open Access academic content, and part of the De Gruyter group, which has over 260 years of publishing history.

Authors can submit papers to one of several submission deadlines during the year. Papers are provided with major/minor revision decisions on a predictable schedule, where we endeavor to assign the same reviewers to major revisions. Authors can address the concerns of reviewers and rebut reviewer comments before a final decision on acceptance is made. Papers accepted for publication by May 15th will be presented at that year's symposium. Note that accepted papers must be presented at PETS.

Authors are encouraged to view our FAQ about the submission process.

Important Dates for PETS 2016

PETS 2016 will be held July 19–22 2016 in Darmstadt, Germany.

Issue 2016.1:
Paper submission deadline: April 15, 2015 (firm)
Rebuttal period: May 23–25, 2015
Author notification: June 15, 2015
Camera-ready deadline for accepted papers and minor revisions (if accepted by the shepherd): July 15, 2015

Papers which were submitted to a previous PETS deadline and invited to resubmit after major revisions can submit the revised paper up to two weeks after the stated deadline. Such papers must however be registered by the usual deadline. Papers which were not submitted to a previous deadline or submissions which were rejected from a previous PETS issue must be submitted by the stated deadline. To be considered as a major revision, papers invited to resubmit must be registered no later than six months after the initial submission; otherwise the paper will be treated as a new submission.

Submission Guidelines
Papers to be submitted to the PET Symposium must be at most 10 pages excluding bibliography and appendices and 15 pages total in double-column ACM format ( PC members are not required to read the appendices, which should only be used to support evidence of the submission's technical validity, e.g., for detailed security proofs. Also, all papers must be anonymized (more information below). Papers not following these instructions risk being rejected without consideration of their merits.

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.

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.

Papers will need to be submitted via the submission server for Issue 3 at:

Anonymization of Submissions
All submitted papers will be judged based on their quality and relevance through double-blind reviewing, where the identities of the authors are withheld from the reviewers. As an author, you are required to make a good-faith effort to preserve the anonymity of your submission, while at the same time allowing the reader to fully grasp the context of related past work, including your own. It is recognized that, at times, information regarding the identities of authors may become public outside the submission process (e.g., if a pre-print is published as a technical report or on a pre-print server) – the PC will ignore this external information. Minimally, please take the following steps when preparing your submission:

Papers describing experiments with users or user data (e.g., network traffic, passwords, social network information), should follow the basic principles of ethical research, e.g., beneficence (maximizing the benefits to an individual or to society while minimizing harm to the individual), minimal risk (appropriateness of the risk versus benefit ratio), voluntary consent, respect for privacy, and limited deception. Authors are encouraged to include a subsection on Ethical Principles if human subjects research is conducted, and such a discussion may be required if deemed necessary during the review process. Authors are encouraged to contact PC chairs before submitting to clarify any doubts.

Accepted papers will be published as an Open Access Journal by De Gruyter Open, the world's second largest publisher of Open Access academic content, and part of the De Gruyter group, which has over 260 years of publishing history. Authors retain copyright of their work. Papers will be published under an open-access policy using a Creative Commons Attribution-NonCommercial-NoDerivs license.

Best Student Paper Award
The Andreas Pfitzmann PETS 2015 Best Student Paper Award will be selected at PETS 2015. Papers written solely or primarily by a student who is presenting the work at PETS 2015 are eligible for the award.

As with the last several years, part of the symposium will be devoted to HotPETs — the "hottest," most exciting research ideas still in a formative state. Further information is available on the HotPETS 2015 page.

Panel Submissions
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 symposium, (2) suggest a duration for the presentation (ideally between 45 and 90 minutes), and (3) suggest some possible presenters.

Submit your proposal in the same manner as a PoPETs paper by the Feb 15 deadline. (All panel proposals received by the Feb 15 deadline will receive full consideration for that year's PETS.) Please begin your panel title with "Panel Proposal:". The program committee will consider panel proposals along with other symposium events and will respond by the paper decision date with an indication of its interest in scheduling the event.
