Standards-based provenance, watermarking, verification, and evidence — for smaller generative-AI providers
A self-serve developer platform that helps smaller generative-AI providers add standards-based provenance (C2PA), connect watermarking, verify outputs, and maintain implementation evidence — mapped measure-by-measure to Section 1 of the EU Transparency Code of Practice, without claiming that any API call constitutes complete Article 50 compliance.
What this is. Technical controls and implementation evidence mapped to Section 1 of the EU Transparency Code.
Designed to help providers implement and evidence Article 50 marking measures. Compliance depends on the customer's complete implementation and circumstances.
What the platform does
Evidence and Code-measure mapping first; signing is the plumbing underneath.
Evidence
An append-only, hash-chained log of each marking event, mapped to Code Section 1 measures, exportable as an implementation-evidence package. Not marketed as an official or prescribed report format.
Detect & verify
A hosted manifest-validation and trust-state report — live today on the verify page. Per-tenant watermark detection is in private beta. Designed to be registry-compatible so it can join the common detection solution when it emerges.
Mark
C2PA manifest with a trusted timestamp, carrying a single permitted assertion set — AI-generated / AI-manipulated. Trust state is disclosed on every manifest. Watermarking via an adapter or your own provider.
Where the responsibility line sits
Every claim is itemized measure-by-measure, so no claim can exceed its row. See the Code-measure mapping for exactly what the platform implements and what remains the customer's responsibility.
Key dates
| Date | Event | Status |
|---|---|---|
| 27 Jul 2026, 18:00 CEST | Deadline for inclusion in the initial Code signatory list (signing stays open after) | Confirmed (Commission FAQ) |
| 2 Aug 2026 | Article 50 applies to all in-scope systems, regardless of when they were placed on the market | Confirmed — current law |
| 2 Dec 2026 | If the agreed Omnibus provision is formally adopted, systems already on the market before 2 Aug would have until this date for Art. 50(2) marking and detection | Agreed in Omnibus; pending final publication in the Official Journal — not yet law |
| 2 Feb 2027 | Watermark-detection interoperability commitment (common API method, embedded signpost, or consortium solution) | A Code signatory commitment — applies to signatories, not automatically to all providers |
