The GIFCT hash-sharing database is the safe and secure industry database of “perceptual hashes” of known terrorist content as defined by GIFCT’s hash-sharing database taxonomy. This database is currently the largest cross-platform technical tool supported by GIFCT in service of its tech company members. Content found by a member company is “hashed” in its raw form, ensuring there is no link to any source original platform or user data. Hashes appear as a numerical representation of the original content, which means they cannot be easily reverse engineered to recreate the content. Each company that is part of the hash-sharing database determines its use of and engagement with the database, depending on (among other things) their own terms of service, how their platform operates, and how they utilize technical and human resources. GIFCT is neither a tech company nor a social media platform, and we do not own or store any source data or personally identifiable information of any users associated with member platforms.
