The Workshop on Hot Topics in Privacy Enhancing Technologies (HotPETs) is held in conjunction with the Privacy Enhancing Technologies Symposium with the goal of fostering new ideas and spirited debates on privacy. HotPETs is talks-only (i.e. no published proceedings) and follows a discussion-oriented format that is especially suited to new and developing work. HotPETs strives to present talks that are informative and engaging, and each year the workshop concludes with an audience vote for the Best Talk Award.

Title:Thank You for Protecting Human Rights

Abstract: I will share real world stories of how privacy-enhancing technologies protect the basic human rights of everyday people in places where these rights are abused daily. By focusing on technologies you know and your right to freedom of expression and information, I hope to: impart why these technologies are crucial for the people living within more than 50 countries whose free expression is regularly suppressed, introduce some areas I think we could be doing more, provide some on-ramps for people in the room to get involved, and make plenty of space for audience driven discussion at the end.

Bio:Dan Blah Meredith is the founding Director of the Open Technology Fund (OTF), a program of Radio Free Asia created in 2012 to support global Internet freedom and privacy-enhancing technologies. Before OTF, he was senior producer and technologist for the Al Jazeera Network and a senior technology fellow at New America Foundation. Notable projects that the OTF has supported include The Tor Project, Open Whisper Systems, Cryptocat, GlobaLeaks, Tor2web, The Guardian Project, Commotion Wireless, Lantern, Serval Project, Briar, NoScript, Qubes OS, and Tails. Over the past decade, Dan has identified as an activist, technologist, journalist, and now funder exploring emerging trends intersecting human rights, transparency, global communication policy and technology, information security, and the Internet.

Call for Talks: HotPETs 2016

9th Workshop on Hot Topics in Privacy Enhancing Technologies (HotPETs 2016)

Held in conjunction with the 16th Privacy Enhancing Technologies Symposium July 22, 2016. The Workshop on Hot Topics in Privacy Enhancing Technologies (HotPETs) fosters new ideas and spirited debates on privacy. We are calling for engaging and informative 10-15 minute talks on hot topics in privacy enhancing technologies (PETs), with each talk to be followed by a 5-10 minute question period. Short, written talk proposals should be sent by May 13th, 2016, to <hotpets16(a-t)> (details below). The nature of HotPETs' discussion-oriented format is especially suited to works in progress and new ideas that have not yet been fully formed.


Topics of interest include, but are not limited to:

  • Anonymous communications and publishing systems

  • Censorship resistance

  • Challenges in deploying PETs

  • Cryptographic protocols with application to privacy

  • Economics of PETs

  • Genetic privacy

  • Human computer interaction with PETs

  • Impact of PETs in the wild

  • Interdisciplinary privacy

  • Legal issues surrounding PETs

  • Location privacy

  • Online surveillance

  • Privacy and identity management

  • Privacy-enhanced access control and authentication

  • Privacy in databases

  • Privacy in social networks

  • Public policy regulating the use and development of PETs

  • Usability of PETs

  • User studies of PETs


Who should submit:

We invite submissions from activists, artists, developers, journalists, lawyers, public servants, researchers, scholars, and any others who can give a compelling, novel talk about privacy and privacy-enhancing technologies. PETS and HotPETS attract world-renowned experts on the research, development, and practice of PETs. If you are excited to give a talk to such a group, and you think they would be excited to hear it, then you should submit. Some example talks:

  • Researcher describing recent research results or a work in progress, especially on a novel or newly-important topic in privacy or security

  • Experiences from an activist working with PETs "on the ground"

  • Software developer describing a recent experience with a privacy-enhancing tool they built

  • Government official discussing interactions between technology and the development of privacy or security-related policy


Travel funds may be available to support attendance at HotPETs, especially for accepted talks. For more information please contact hotpets16(a-t)


What to submit:

We invite two-page talk proposals that give an overview of what you intend to present, including any results or conclusions you intend to share. HotPETs strives for engaging talks and focused discussions, and so proposals should display exciting ideas that can be communicated clearly and with brevity.


We encourage you to link to additional sources of your work (e.g., software, videos, websites, papers) within your proposal. The HotPETs chairs will strive to incorporate these additional sources into the review process, although full review of material beyond what is contained in the submission text is not guaranteed.


A proposal must include a title and a list of authors responsible for the work to be presented (one of whom must give the talk). It must be no more than two pages including references. It must be submitted as a Word or PDF document, and we recommend that proposals use either this Word template or this LaTeX template. For detailed information on using these templates, see the ACM SIG Proceedings templates.


HotPETs has no official proceedings, but accepted submissions will be made available on the HotPETs website (authors may revise them after acceptance). Authors may have the option to include talk-related resources, such as slides or software, on the HotPETs website. With speaker consent, recordings of HotPETs talks may be made during the workshop and put online.


Submission Review:

The HotPETs chairs will review the submissions and make the final decisions on acceptance. The chairs may request external input or advice to make fully informed decisions.


The chairs will seek to accept submissions that have the potential to create an engaging workshop for speakers and attendees. Accepted submissions may include those that provoke interesting discussion, provide unique insight or value to the PETs community, share new and emerging PETs-related research, and have the potential to expand engagement between the PETs community and PETs users.


The chairs seek submissions that are complete and concise. They should provide a full overview of the proposed talk, including (if available) any conclusions or findings that are to be presented.


HotPETs Best Talk Award:

A goal of HotPETs is to present talks that are informative, engaging, and even entertaining. To recognize such talks, each year HotPETs concludes with a vote by the audience for its favorite talk. The talk with the most votes wins the Best Talk Award!
