4 Overview of the Lantern Program The Lantern Program is a framework for sharing information related to harmful threats (known as “signals”) for the purpose of combating online child sexual exploitation and abuse (“OCSEA”). The Lantern Program seeks to facilitate cross-industry knowledge sharing, proactive detection of OCSEA, and industry-wide moderation of known or suspected child sexual abuse material (“CSAM”). The goal of signal sharing is to supplement company participants’ individual content moderation and trust and safety efforts by providing information that helps companies identify cases of OCSEA or offenders who may be operating across different platforms. 4.1 Signal Sharing The Lantern Program allows signal sharing among participants using a database built on Meta’s ThreatExchange platform. Signals shared on ThreatExchange may include hashes (including of known CSAM), URLs, common keywords or phrases, text 昀椀elds, search terms, or basic subscriber and user information (such as name, date of birth, gender, or contact information) that may indicate actual or potential cases of OCSEA. Participants are expected to manually review the signals that are shared in the database and establish violation of their own platform policies before taking action based on signals. Signals on ThreatExchange can be shared or accessed via a user interface or an API. 4.2 Participation Participation in the Lantern Program is currently limited to companies operating in the tech industry such as social media and other user-generated content platforms, messaging apps, and 昀椀le-sharing services. There are currently 10 companies participating in the Lantern Program; some participants are members of the Tech Coalition, while others are not. To be eligible to join the Lantern Program, prospective participants are required to: • Identify internal points of contact responsible for various aspects of the company’s involvement in the Lantern Program, • Have publicly accessible platform policies, including privacy policies and user content / conduct policies, as well as public reporting mechanisms for suspected child sexual exploitation or abuse on the platform, BSR TECH COALITION HUMAN RIGHTS IMPACT ASSESSMENT 19
