Welcome to all PEPR '20 speakers!


If you have questions, please contact or your Program Co-Chairs, Lorrie Cranor and Lea Kissner,

To-Do List

  1. Sign your Consent to Publish form.
    USENIX requires a signed consent form from all presenters, which allows us to publish the slides and/or video of your talk. USENIX makes these freely available to the public as part of our commitment to open access. Please review and e-sign the PEPR '20 Consent Form for Talks and Panels. If your company requires that you sign its speaker release form instead, please send the completed version to
  2. Register for the conference.
    The USENIX Conference Department will contact you with instructions for registering online.
  3. Read the USENIX Event Code of Conduct and USENIX Event Guidelines for Speakers.
    Please ensure your talk follows the guidelines outlined in the Code of Conduct for USENIX Events and Online Community Spaces.
  4. Prepare and submit your presentation materials by Friday, September 25, 2020.
    Speakers must record videos of their presentations and prepare their slide decks prior to the conference. Submit your videos and slide decks via the submissions system. Specification requirements for both the videos and slides are below.

Use of Images, Audio, and Video in Your Materials

It is very important that you secure permission to use copyright-protected materials in your slide deck, video, or other materials used at a conference or submitted for publication. Even when an item has a Creative Commons license, you must read and comply with the terms of the license.

USENIX receives copyright infringement notices from time to time, resulting from authors or speakers using copyright-protected materials without proper licensing or attribution. When this happens, we have to unpublish the work in question until/unless the issue is resolved. Licensing fees may be incurred, even when the work is unpublished, and USENIX will bill the author or speaker for any costs incurred. When possible, USENIX will refer the complainant directly to the author or speaker, who will be solely responsible for resolving the complaint.

Video Specifications

For our virtual event, speakers must pre-record a video of their talk. This video will be played live for you by the USENIX staff during the event at your designated time slot in the program. Speakers are expected to be present in the Zoom webinar when their video is played and to take live audience questions immediately following their video (5–7 minutes of Q&A for long talks and 2–5 minutes of Q&A for short talks). Both the video and slides will also be posted on the USENIX website in advance of the conference to allow participants to view the material and start discussing the talk on a Slack channel (Slack workspace and channel information will be provided after registration and before the event occurs).
