AI content marking for EU AI Act Article 50 compliance.

01

Proofcan signs an AI-generated image with C2PA provenance, embeds an invisible watermark, and files the record in a public registry. Built for EU AI Act Article 50.

Three layers, so one can survive.

Metadata gets stripped. Files get re-encoded. A single mark is a single point of failure, so Proofcan writes three.

01Sign

A C2PA manifest declares the image as AI-generated, signed and timestamped to RFC 3161.

02Watermark

An invisible watermark carries the lookup ID and survives compression, resizing and format changes.

The hash and lookup ID go into the registry, so the record outlives the file itself.

a record that keeps moving

Lookup IDs and timestamps only — no file names, no accounts. A sample of the register's shape; the live feed lands with the aggregate endpoint.

what proofcan does not claim

  • It does not make you compliant. Article 50 obligations stay with you; this is tooling that helps you meet them.
  • It does not guarantee a watermark is permanent. Heavy edits, crops and screenshots can defeat any watermark.
  • It is not legal advice. Talk to your own counsel about how Article 50 applies to your business.
