Content Moderation in an End-to-End Encrypted World

Content Moderation in an End-to-End Encrypted World

Friday, April 1, 2022
10:00 AM - 11:00 AM

Join the Stanford Internet Observatory, the Greater Washington DC Chapter of the Internet Society, and the Center for Democracy and Technology on April 1 to discuss Content Moderation in an end-to-end encrypted world. Speakers include Riana Pfefferkorn, Research Scholar at the Stanford Internet Observatory, Mallory Knodel, Chief Technology Officer at the Center for Democracy and Technology, and Ryan Polk, Director of Internet Policy at the Internet Society.

In recent years, we have seen law enforcement agencies and policymakers shift the focus of the encryption debate to social media platforms and messaging services’ content moderation policies and practices. While not always explicitly targeting end-to-end encryption (E2EE), proposals to regulate social media companies, including the proposed EARN IT Act bill in the U.S., MeitY’s Intermediary Guidelines in India, and the proposed Online Safety Bill in the U.K. could have serious implications for end-to-end encrypted (E2EE) services.

As this policy debate continues, companies have proposed methods to moderate content on E2EE platforms that raise privacy concerns, such as those that utilize machine learning and client-side scanning. To better inform the debate, researchers at CDT and the Stanford Internet Observatory have produced timely research to assess the impact that various techniques would have on the E2EE systems of online service providers.

This event will feature presentations on critical research in this area, and will highlight global efforts to defend encryption against movements to undermine it. These presentations will be followed by an open discussion on the road ahead for content moderation in an end-to-end encrypted world.
