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. The 19th PETS event will be organized by KTH and held in Stockholm, Sweden 2019 (exact dates TBD). 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 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 is 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. PoPETs does not have article processing charges (APCs) or article submission charges.

Submitted papers to PETS/PoPETs should present novel practical and/or theoretical research into the design, analysis, experimentation, or fielding of privacy-enhancing technologies.

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 versions. Papers accepted for an issue in the PoPETS 2019 volume must be presented at the symposium PETS 2019.

Submit papers for PoPETs 2019, Issue 1 at https://submit.petsymposium.org/2019.1/. Please see the submission guidelines and our FAQ for more information about the process.

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.

Suggested topics include but are not restricted to:
------------------------------------------------------

Behavioural targeting
Blockchain technologies applied to privacy
Building and deploying privacy-enhancing systems
Crowdsourcing for privacy
Cryptographic tools for privacy
Data protection technologies
Differential privacy
Economics and game-theoretical approaches to privacy
Empirical studies of privacy in real-world systems
Forensics and privacy
Human factors, usability and user-centered design for PETs
Information leakage, data correlation and generic attacks to privacy
Interdisciplinary research connecting privacy to economics, law, ethnography, psychology, medicine, biotechnology, human rights
Location and mobility privacy
Machine learning and privacy
Measuring and quantifying privacy
Mobile devices and privacy
Obfuscation-based privacy
Policy languages and tools for privacy
Privacy in cloud and big-data applications

Caspar Bowden Award for Outstanding Research in Privacy Enhancing Technologies
---------------------------------------------------------------------------------
You are invited to submit nominations for the 2019 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 monument.

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, 2017 until March 30, 2019.

Andreas Pfitzmann Best Student Paper Award
----------------------------------------------
The Andreas Pfitzmann PETS 2019 Best Student Paper Award will be selected at PETS 2019. Papers written solely or primarily by a student who is presenting the work at PETS 2019 are eligible for the award.

HotPETs
--------
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 will be published on the PETS 2019 website soon.
