Labeling AI Content

Name: AI Content Labeling — C2PA & Watermarking for AIGC | Trufo
Brand: Trufo

How to set up AI labeling with Trufo to meet compliance requirements.

Updated July 1, 2026

For AI platforms, creative agencies, and other organizations that generate or distribute AI-generated and AI-modified content. Trufo's suite of products is built specifically to meet the EU AI Act and other AI-labeling regulations coming into force around the world.

The EU AI Act Code of Practice on transparency of AI-generated content was published in June 2026.

New providers of generative AI released after August 2, 2026 must comply.
Existing providers of generative AI who sign the Code of Practice must comply by December 2, 2026.

C2PA & AI Labeling Regulations

AI labeling regulations are taking effect around the world, with fines and penalties looming. The only solution that will work internationally is C2PA.

At a Glance

Here is an overview of the main AI labeling regulations, as of July 2026:

Jurisdiction	Instrument	Effective	Max Penalty
EU	AI Act Art. 50	Aug 2, 2026	€15M / 3% turnover
US	COPIED Act (pending)	TBD	FTC enforcement
China	CAC Labeling Measures	Sep 1, 2025	CAC enforcement
S. Korea	Basic AI Act	Jan 22, 2026	KRW 30M
UK	DSIT / Ofcom (draft)	TBD	TBD

The EU AI Act is the most imminent, and requires both cryptographic metadata and imperceptible watermarks from all AI providers (which applies not just to AI model providers, but any company that produces AI-generated or AI-modified content). There is also an interoperability requirement, so you cannot simply invent your own method to comply; however, Trufo products will work.

EU AI Act Guide

The US COPIED Act takes a more creator-centric approach: all AI providers must allow content owners to attach provenance to the content, and this provenance must not be tampered with or removed.

The Components

Trufo provides all the components required for full compliance.

Using the Signing API

Any organization using Trufo's Signing API can immediately attain compliance simply by signing all media that they publish or otherwise distribute. The AI disclosure assertion should be used and, except in cases where metadata will not be stripped, the Trufo watermark should be enabled. Note that the watermark can be set to per-disclosure (recovers the shared AI disclosure assertion) or per-content (recovers a specific C2PA manifest).

Immediate Compliance

There are many AI labeling regulations, each requiring multiple components working in tandem. With Trufo, you simply need to integrate a few clean API calls into your workflow.

Ergonomic AI Disclosures

Trufo allows you to efficiently manage and organize different AI disclosures for different tranches of AI-generated or AI-modified content via API and SDK.

Watermarks for Provenance

In order to satisfy the EU AI Act, the watermark needs to be interoperable, so simply adding on a traditional watermark or an open-source watermark is not sufficient. Through PawPrint, Trufo provides the first suite of watermarks designed for provenance.

Audit-Ready

Every signing event is logged, so that if auditors or regulators come knocking, you can pull the data you need. Trufo will also be providing automated compliance reports in the future, once the requirements for these reports are more clear.

CAWG Identity Support

By adding CAWG, you are not simply marking your content as “AI” in a derogatory manner; you are also adding creative credentials that can carry brand and attribution value.

One Integration, Many Jurisdictions

This single implementation covers requirements across the EU, US, China, and more. This is more efficient and reliable than tackling each region separately.

Building a C2PA Generator Product

If you are building your own C2PA Generator Product, you will need a C2PA Claim Signing Cert. If you support artists, you will also want to resell CAWG Identity Credentials. In both cases, you will also want to add on PawPrint as an interoperable watermark.
