Papers MUST be anonymized
12 pages excluding bibliography & non-essential appendices (20 pages max)
Use SOUPS MS Word or LaTeX templates
More guidance:
See the common pitfalls document. (This document only addresses quantitative work, but we welcome other approaches.)

We invite authors to submit original papers describing research or experience in all areas of usable privacy and security. We welcome a variety of research methods, including both qualitative and quantitative approaches. Topics include, but are not limited to:

All submissions must relate to both human aspects and either security or privacy. Papers on security or privacy applications that do not address usability or human factors will not be considered.

Papers need to describe the purpose and goals of the work, cite related work, show how the work effectively integrates usability and security or privacy, and clearly indicate the innovative aspects of the work or lessons learned as well as the contribution of the work to the field.

Papers must use the SOUPS formatting template (available for MS Word or LaTeX) and be up to 12 pages in length, excluding the bibliography and any supplemental appendices. Authors have the option to attach to their paper supplemental appendices containing study materials (e.g. surveys) that would not otherwise fit within the body of the paper. These appendices may be included to assist reviewers who may have questions that fall outside the stated contribution of your paper, on which your work is to be evaluated. Reviewers are not required to read any appendices so your paper should be self contained without them. Accepted papers will be published online with their supplemental appendices included. Submissions must be no more than 20 pages including bibliography and appendices. For the body of your paper, brevity is appreciated, as evidenced by the fact that many papers in prior years have been well under this limit. All submissions must be in PDF format and should be blinded.

Submit your paper electronically at

Anonymization: Reviewing is double blind: Author names and affiliations should not appear on the title page, and papers should avoid revealing the authors' identity in the text. Any references to the authors' own work should be made in the third person. Contact the program chairs at if you have any questions.

Submissions that violate these requirements may be rejected without review.

Registering & submitting your paper: Technical papers must be registered by 5pm, US Pacific time, March 6 and submitted by 5pm, US Pacific time, March 13. These are hard deadlines! (Registering a paper in the submission system requires filling out all the fields that describe the submission, but does not require uploading a PDF of the paper.) Authors will be notified of technical paper acceptance by May 19, and camera-ready final versions of technical papers will be due June 12.

Rebuttals: This year, authors of submitted SOUPS papers will be given a chance to see and correct factual errors in early-round reviews during the rebuttal period, April 20-24.

Accepted papers will be published by the USENIX Association, and will be freely available on the USENIX and SOUPS websites. Authors will retain copyright of their papers. Submitted papers must not significantly overlap papers that have been published or that are simultaneously submitted to a peer-reviewed venue or publication. Any overlap between your submitted paper and other work either under submission or previously published must be documented in a clearly-marked explanatory note at the front of the paper. State precisely how the two works differ in their goals, any use of shared experiments or data sources, and the unique contributions. If the other work is under submission elsewhere, the program committee may ask to review that work to evaluate the overlap. Please note that program committees frequently share information about papers under review and reviewers usually work on multiple conferences simultaneously. Technical reports are exempt from this rule. If in doubt, please contact the program chairs for advice. You may also release pre-prints of your accepted work to the public at your discretion.

Authors are encouraged to review: Common Pitfalls in Writing about Security and Privacy Human Subjects Experiments, and How to Avoid Them. Note that this paper addresses research work taking an experimental and quantitative approach, with hypothesis testing and statistical inference. However, SOUPS welcomes submissions that take other approaches, and recognizes that other methodological considerations will be appropriate.

User experiments 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 in their submissions explanation of how ethical principles were followed, and may be asked to provide such an explanation should questions arise during the review process.

We seek poster abstracts describing recent or ongoing research or experience in all areas of usable privacy and security. SOUPS will include a poster session in which authors will exhibit their posters. Accepted poster abstracts will be distributed to symposium participants and made available on the symposium web site. Please follow the final submission formatting instructions when preparing your poster abstract to avoid the need for revision after acceptance decisions are made.

We also welcome authors of recent papers (2014 to 2015) on usable privacy and security to present your work at the SOUPS poster session. Please submit in a PDF file:

  1. the title and abstract of your conference paper,
  2. full bibliographical citation, and
  3. a link to the published (official) version, instead of the regular poster abstract.

In addition to the required poster abstract, authors are encouraged to optionally submit a draft of their poster (poster size: 32 x 40 in) to receive feedback before the conference. Please scale your poster to normal page size (A4 or letter) for submission.

To make poster presentations more interactive we also encourage you to demo your project alongside your poster. Due to space constraints, we can only support a limited number of such poster demos. If you would like to be considered for this demo option, please describe your demo requirements (e.g., a table, a power outlet) separately and submit them with your poster abstract.

This year, we will also be awarding prizes for the best posters. SOUPS attendees will be given voting forms to complete during the poster session. Posters with the highest votes will be awarded.

Poster submission requirements:

Submissions will close at 5pm, US Pacific time, May 26, 2015.


A continuing feature of SOUPS is a session of 5-minute talks. These could include emerging hot topics, preliminary research results, practical problems encountered by end users or industry practitioners, a lesson learned, a research challenge that could benefit from feedback, a war story, ongoing research, a success, a failure, a future experiment, tips and tricks, a pitfall to avoid, etc. If you would like to participate in the lightning talk session, please email by May 26, with your name, affiliation, the title, and a brief abstract (up to 200 words) of your lightning talk. Confirmations of a lightning talk slot will be given by June 9. Additional proposals will be accepted after the deadline if there is still room on the program. You will need to deliver your slides for the 5-minute talk to the Lightning Talks and Demos Chair via the same email address before July 22.

SOUPS is planning to include a demo session, in which participants will have the opportunity to interactively introduce to the full SOUPS audience their new, cool, and exciting visualization, user interface, or interaction paradigm related to security and privacy. Demo presentations will be 5 to 10 minutes in length, and should convey the main idea of the interface and one or more scenarios or use cases. To be considered for a presentation, a proposal describing the demonstration should be emailed to by May 26. Demo proposals should be no longer than two pages, and should use the formatting guidelines described above for poster abstracts. Confirmations of demo slots will be given by June 9.
