Not just a label. A complete evidence package.

Every Nutrition Label bundles the media, the metadata, and the supporting documents that prove its origin — license, contract, model release, split sheet, RAW session. Referenced from the C2PA manifest so anyone can trace the paper trail behind the asset.

  • Unlimited supporting documents per asset
  • Referenced — not parsed — from the C2PA manifest
  • Every file hashed and anchored to Hedera

What's inside

Four proofs, one label.

C2PA Manifest

A signed manifest embedded in the asset, referencing the label and every document.

Neural Watermark

Invisible, tamper-resistant signal that survives re-encoding, screenshots, and clips.

Content Fingerprint

Content-derived hash so we can recognize the asset even without its manifest.

Hedera Notary

A public, immutable timestamp of the manifest and label hash.

How it works

Three steps. That's the whole product.

STEP 01
Upload asset

Image, video, or audio. Drag it into the console.

STEP 02
Fill the Nutrition Label

Creator, rights, license, origin. Simple fields — no parsing.

STEP 03
Attach supporting documents

License, contract, consent form, RAW session. Anything that proves origin.

Behind the scenes we generate the C2PA manifest, embed the watermark, hash everything, and anchor it on Hedera. You just clickCreate Nutrition Label.
