26 January 2022 GIFCT

GIFCT’s hash-sharing database (HSDB) is a cross-platform database that enables the sharing of “hashes” (or “digital fingerprints”) of known terrorist and violent extremist content (TVEC) between member platforms in a secure, efficient, and privacy-protecting manner. The HSDB allows GIFCT members to identify and act on TVEC quickly, in accordance with their respective policies and terms of service. Learn more about the HSDB here.
