Media
Media provenance
Anchored at capture, so a synthetic re-cut cannot inherit the proof.
The problem
An image or video carries no reliable record of where it came from, and generated media is now indistinguishable from a recording at a glance.
01
What is anchored
Images and video, anchored at the moment of capture.
02
When it is revealed
Anchored at capture; the proof travels with the file.
03
Who checks it
Newsrooms, platforms and viewers. A re-cut produces a different hash and fails the check.
The cycle is identical
Canonicalise the artifact, hash it with a secret nonce, anchor the fingerprint, then reveal inside the window. Only the schema and the window change from one application to the next.
