Disclosure Ledger

For agencies & brands publishing images

A durable declaration trail when provenance gets stripped

EU AI Act Art. 50 transparency obligations for AI-generated or manipulated content begin applying 2 August 2026. Publishing pipelines often strip embedded provenance (C2PA / Content Credentials). Disclosure Ledger lets you drop a publish-bound image, hash it in-browser, self-report an AI declaration, and keep a permanent public record page — plus CSV export.

The honest problem

  • Art. 50 raises the bar for transparency around AI-involved imagery — buyers need an audit trail they can point to, not a one-off email.

  • CMS uploads, CDNs, and social crops routinely discard embedded provenance metadata. Relying only on “the file still has C2PA” is fragile.

  • Teams still need a lightweight place to say: here is the hash of what we intended to publish, and here is our self-reported declaration.

This product does not interpret the law for you and does not claim your declarations satisfy Art. 50. Talk to counsel for legal adequacy.

How it works

Full walkthrough
  1. 1

    Drop image

    Client-side only for hashing — image bytes are not uploaded in this MVP.

  2. 2

    Hash + scan

    Browser computes SHA-256 and runs a best-effort provenance marker scan (not validation).

  3. 3

    Declare

    Self-report yes / no / partial AI involvement and optional notes.

  4. 4

    Public record

    Permanent /r/[id] page + CSV export. Always labeled unverified.

Frequently asked questions

Does this make me Art. 50 compliant?
No. Disclosure Ledger does not make you EU AI Act Article 50 compliant. It only stores a self-reported, unverified declaration and content-hash audit trail. Legal adequacy requires your own counsel and processes — not this product.
Does Disclosure Ledger verify or sign my images?
No. We do not verify authenticity, cryptographically sign or attest images, or certify authorship. Records are publisher-submitted declarations plus a hash.
What is Disclosure Ledger?
Disclosure Ledger is a product by Atlas AG: a declaration / audit-trail tool for publish-bound images. You hash an image in-browser, self-report AI involvement, and keep a permanent public record URL and CSV export.
Why might embedded provenance not be enough alone?
CMS uploads, CDNs, and social crops often strip embedded provenance such as C2PA / Content Credentials. Teams may still want a separate, durable record of what they intended to publish and what they declared.
Are public record pages meant for search engines?
No. Public /r/[id] record pages are marked noindex so user records are not spammed into search results. Marketing pages remain indexable.

What we never claim

  • No claim of legal compliance, signing, or verification.
  • No claim that records prove authenticity or authorship.
  • No claim that the provenance scan is a full C2PA implementation.
  • Every public record page states declarations are self-reported and unverified.
