Call for Papers

21st Privacy Enhancing Technologies Symposium (PETS 2021)

July 12–16, 2021

Location: The Internet

The annual Privacy Enhancing Technologies Symposium (PETS) brings together privacy experts from around the world to present and discuss recent advances and new perspectives on research in privacy technologies. Papers undergo a journal-style reviewing process, and accepted papers are published in the journal Proceedings on Privacy Enhancing Technologies (PoPETs).

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 published by Sciendo, part of De Gruyter, which has over 260 years of publishing history. PoPETs does not have article processing charges (APCs) 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. In addition to accept and reject decisions, papers may receive resubmit with major revisions decisions, in which case authors are invited to revise and resubmit their article to one of the following two issues. We endeavor to assign the same reviewers to revised submissions. Papers accepted for an issue in the PoPETs 2021 volume must be presented at the PETS 2021 symposium. Please view our FAQ for more information about the process.

Submission Guidelines
The submission guidelines contain important submission information for authors. Please note especially the instructions for anonymizing submissions and for ensuring ethical research. Papers must be submitted via the PETS 2021 submission server. The submission URL is:

Issue 4
Paper submission deadline: February 28, 2021 (firm)
Rebuttal period: April 7–9, 2021
Author notification: May 1, 2021
Camera-ready deadline for accepted papers and minor revisions (if accepted by the shepherd): June 15, 2021

Authors invited to resubmit with major revisions can submit the revised (full) paper two weeks after the stated deadline. Such papers must, however, be registered with an abstract by the usual deadline. All other papers than these major revision resubmissions must be submitted by the stated deadline, including papers submitted to and rejected from previous issues. To benefit from the two-week deadline extension, major revisions must be submitted to one of the two issues following the decision. Major revisions submitted to later issues are treated as new submissions, due by the regular deadline and possibly assigned to new reviewers.


Papers submitted to PETS/PoPETs should present novel practical and/or theoretical research into the design, analysis, experimentation, or fielding of privacy-enhancing technologies. Note that a paper's relevance to privacy applications is crucial for our community. PETS is open to topics from the wider area of security and privacy (cryptographic primitives, security mechanisms, differentially-private mechanisms, etc.) 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.).

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.

Caspar Bowden Award for Outstanding Research in Privacy Enhancing Technologies
You are invited to submit nominations for the 2021 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, 2019 until March 30, 2021.

Andreas Pfitzmann Best Student Paper Award
A winner of the Andreas Pfitzmann PETS 2021 Best Student Paper Award will be selected at PETS 2021. Papers written solely or primarily by a student who is presenting the work at PETS 2021 are eligible for the award.

As usual, part of the symposium will be devoted to HotPETs — the "hottest," most exciting research ideas still in a formative state. Further information will be published on the PETS website in early 2021.
