General information about PETs Submit your paper

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
27th PETS is expected to be an event with a physical gathering held in
somewhere in Europe (TBA). 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 strongly 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 strictly
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. Please see the review process page
for more information.

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 2027 submission server. The submission URL is:
https://submit.petsymposium.org/.

Author Rebuttals

The authors will have a chance to rebut/answer reviewer
concerns/questions through a short rebuttal phase. Reviewers are asked
to take the rebuttals into consideration during the discussion.The
authors will be able to submit a separate, 250-word rebuttal response
to each individual review.

Revision Process

Authors who are 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 it 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

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
2027 may not be resubmitted until Issue 1 of Volume 2028. This policy
enables authors ample time to substantially improve their papers and
helps mitigate the overburdening of reviewers.

Scope (Refined for PoPETs 2027)

Papers must present novel research into privacy-enhancing technologies
(PETs) and the social, cultural, legal, or situational contexts in
which they are used. Interdisciplinary work is welcome as long as it
clearly shows how the contributions impact PETs.

Please follow the guidelines given below to ensure that your
submission passes desk review and receives a full review by the
program committee. You may ask the chairs for clarification of scope
before the submission deadline.

    Papers must have strong ties to privacy in digital systems.

    The core contribution must be relevant to real-world privacy applications.
        The first page must clearly state how the work is relevant to
        real-world privacy applications.

        Relevance to real-world privacy applications must also be
        present throughout the entire paper by dedicating a
        substantial portion of the submission to work that is
        traditionally considered practical or applied.

    For contributions of theoretical nature (e.g., improvements on
    cryptographic primitives or improvements on differential privacy),
    the paper should provide details about how the proposed advances
    would be integrated into a real-world application.

    Improvements motivated by real applications, but presented in
    isolation without connection to those applications, do not
    demonstrate relevance in practice and are therefore out of scope.

    Papers with empirical evaluations must show a clear connection to
    privacy and to real-world applications.

    Evaluations that are based on purely synthetic datasets, or on
    non-privacy-relevant datasets (e.g., MNIST, CIFAR, or SVHN) must
    contain a well-marked paragraph explaining why the results of the
    evaluation can be extrapolated to real-world use cases where
    privacy is of relevance.

    Papers that treat privacy as a superficial application domain
    (e.g., if the only relationship to privacy is a privacy-related
    dataset) do not demonstrate relevance to real-world privacy
    problems and are therefore out of scope.

Suggested topics include but are not restricted to:

    Anonymous communication and censorship resistance
    Blockchain privacy
    Building and deploying privacy-enhancing systems
    Cloud computing and privacy
    Compliance with privacy laws and regulations
    Cryptographic tools for privacy
    Data protection technologies
    Defining and quantifying privacy
    Differential privacy and private data analysis
    Economics and game-theoretical approaches to privacy
    Forensics and privacy
    Genomic and medical privacy
    Human factors, usability, and user-centered design of privacy technologies
    Information leakage, data correlation, and abstract attacks on privacy
    Interdisciplinary research connecting privacy to economics, law,
      psychology, etc.
    Internet of Things privacy
    Location privacy
    Machine learning and privacy
    Measurement of privacy in real-world systems
    Mobile devices and privacy
    Policy languages and tools for privacy
    Profiling and data mining
    Social network privacy
    Surveillance
    Traffic analysis
    Transparency, fairness, robustness, and abuse in privacy systems
    Web privacy

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):

    Source code (e.g., system implementations, proof of concepts)
    Datasets (e.g., network traces, raw study data)
    Scripts for data processing or simulations
    Machine-generated proofs
    Formal specifications
    Build environments (e.g., VMs, Docker containers, configuration scripts)

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
petsymposium.org with a link to the artifact along with an artifact
badge so that interested readers can find and use your artifact.

Artifact Review Committee
    TBD

Tadpole Reviewers

    Tadpole Reviewers are a way for more junior members of the PETs
    community to participate in reviewing without formally joining the
    PC. They provide at most one additional round 2 review per issue,
    as well as participate in the discussion and decision making for
    the paper they are assigned. Tadpole reviews are additional
    reviews and do not replace reviews written by full PC members.
