Call for Papers

25th Privacy Enhancing Technologies Symposium (PETS 2025)

July, 2025 (dates to be confirmed)

Washington, DC and Online

The annual Privacy Enhancing Technologies Symposium (PETS) brings together experts from around the world to present and discuss recent advances and new perspectives on research in privacy technologies. The 25th PETS will be a hybrid event with a physical gathering held in Washington, DC, USA and a concurrent virtual event. Papers undergo a journal-style reviewing process, and accepted papers are published in the journal Proceedings on Privacy Enhancing Technologies (PoPETs). Authors of accepted papers are encouraged to attend and present at the physical event, where their presentations can be recorded for the virtual event and where they can participate directly in in-person research, technical, and social activities. However, in-person attendance is not required for publication in the proceedings.

PoPETs, a scholarly, open-access journal for research papers on privacy, provides high-quality reviewing and publication while also supporting the successful PETS community event. PoPETs is self-published and does not have article processing charges or article submission charges.

Authors can submit papers to PoPETs four times a year, every three months, and are notified of the decisions about two months after submission. Authors will receive a decision of accept, revise, or reject; those receiving revise will be invited to revise their article with the guidance of a revision editor according to a well-defined set of revision criteria and will have up to four months to attempt to complete the required revisions. Authors of rejected papers must skip a full issue prior to resubmission.

Submission Guidelines

The submission guidelines contain important submission information for authors. Please note especially the instructions for anonymizing submissions, for ensuring ethical research, and for using AI in writing or editing the manuscript. Papers must be submitted via the PETS 2025 submission server. The submission URL is:

Review Process (New for 2025)

Authors invited to revise their submissions will be provided with a set of revision criteria that must be satisfactorily completed before their paper can be accepted. Authors of such papers will not resubmit to the next issue, but will instead be assigned a revision editor who will guide the revision process by interactively reviewing new versions of the paper and providing feedback and guidance on the changes necessary for acceptance. Authors will be instructed to propose a revision schedule that is agreeable to the revision editor. Authors may complete the necessary changes as soon as is practical but no later than four months following the author notification deadline: revisions that are accepted by the revision editor within 1 month of the author notification will appear in that issue, while revisions that are accepted by the revision editor between 1-4 months of the author notification will appear in the following issue. Not all papers that receive a revise decision will be accepted: papers that do not adequately incorporate the required revisions by the following issue's revision deadline will be rejected. Please see the review process page for more information.

Resubmission of Rejected Papers (New for 2025)

Authors of rejected papers may consider resubmitting to a future issue of PoPETs, but must skip one full issue before resubmission. For example, papers that are rejected from Issue 1 may not be resubmitted until Issue 3 or later. This policy follows into future volumes as well. For example, papers that are rejected from Issue 3 of Volume 2025 may not be resubmitted until Issue 1 of Volume 2026. This policy enables authors ample time to substantially improve their papers and helps mitigate the overburdening of reviewers.

Scope (New for 2025)

Papers submitted to PETS/PoPETs should present novel practical and/or theoretical research into the requirements, design, analysis, experimentation, or fielding of privacy-enhancing technologies and the social, cultural, legal, or situational contexts in which they are used. PETS is also open to interdisciplinary research examining people’s and communities’ privacy needs, preferences, and expectations as long as it is clear how these findings can impact the design, development, or deployment of technology with privacy implications.

Note that a paper's relevance to privacy applications is crucial. PETS is open to topics from the wider area of security and privacy as long as it is clear how these serve to improve or understand privacy in technology (e.g., it includes a use case, evaluation on real data, integration with an application, etc.) in real systems. A paper that makes significant contributions in an area such as theoretical cryptography but fails to clearly tie its contributions to improving or understanding privacy in real systems is unlikely to be accepted. The chairs and the program committee, at their discretion, may reject papers based on scope

Suggested topics include but are not restricted to:

We also solicit Systematization of Knowledge (SoK) papers on any of these topics: papers putting together existing knowledge under some common light (adversary model, requirements, functionality offered, etc.), providing novel insights, identifying research gaps or challenges to commonly held assumptions, etc. Survey papers, without such contributions, are not suitable. SoK submissions should include "SoK:" in their title and check the corresponding option in the submission form.

Artifact Review
PoPETs reviews and publishes digital artifacts related to its accepted papers. This process aids in the reproducibility of results and allows others to build on the work described in the paper. Artifact submissions are requested from authors of all accepted papers, and although they are optional, we strongly encourage you to submit your artifacts for review.

Possible artifacts include (but are not limited to):

Artifacts are evaluated by the artifact review committee. The committee evaluates the artifacts to ensure that they provide an acceptable level of utility, and feedback is given to the authors. Issues considered include software bugs, readability of documentation, and appropriate licensing. After your artifact has been approved by the committee, we will accompany the paper link on with a link to the artifact along with an artifact badge so that interested readers can find and use your artifact.

Caspar Bowden Award for Outstanding Research in Privacy Enhancing Technologies
You are invited to submit nominations for the 2025 Caspar Bowden Award for Outstanding Research in Privacy Enhancing Technologies. The Caspar Bowden PET award is presented annually to researchers who have made an outstanding contribution to the theory, design, implementation, or deployment of privacy enhancing technologies. It is awarded at PETS and carries a cash prize as well as a physical award statue. Any paper by any author written in the area of privacy enhancing technologies is eligible for nomination. However, the paper must have appeared in a refereed journal, conference, or workshop with proceedings published in the period from April 1, 2023 until March 30, 2025.

Andreas Pfitzmann Best Student Paper Award
A winner of the Andreas Pfitzmann PETS 2025 Best Student Paper Award will be selected at PETS 2025. Papers written solely or primarily by a student who is presenting the work to PETS 2025 are eligible for the award.

Artifact Award
A winner of the PETS 2025 Artifact Award will be announced at PETS 2025. Artifacts for papers accepted to PETS 2025 are eligible for the award.

HotPETs and FOCI
As with the last several years, part of the symposium will be devoted to HotPETs — the "hottest," most exciting research ideas still in a still in a formative state — and FOCI, a workshop showcasing the latest results from the Free and Open Communication on the Internet community. Further information will be published on the PETS website in early 2025.
