Is your AI content Article 50 compliant? A checklist for SaaS companies

EU AI Act Article 50 becomes enforceable on August 2, 2026. Here's how to determine if your SaaS product is affected and what you need to do before the deadline.

Is your AI content Article 50 compliant? A checklist for SaaS companies

The EU AI Act Article 50 becomes enforceable on August 2, 2026. If your SaaS product generates AI content for users in the EU, you almost certainly have obligations under this article — and you may not even know it.

This checklist helps you determine your compliance status and what steps to take.

First: Does Article 50 apply to you?

Article 50 applies to providers and deployers of AI systems that generate synthetic content. You are a provider if you built or fine-tuned an AI model. You are a deployer if you integrated an existing AI model (DALL-E, Stable Diffusion, Midjourney, etc.) into a product used by EU residents.

Most SaaS companies with AI features are both.

Article 50 applies if you:
  • Generate AI images, videos, audio, or text for end users
  • Have EU users (even a small percentage)
  • Use any generative AI model — whether API-based or self-hosted

The three-layer requirement

The EU Code of Practice mandates a multi-layered marking approach:

  • Machine-readable metadata — Content must carry cryptographic provenance information (C2PA standard)
  • Watermarking — Content must contain an imperceptible signal that survives basic transformations
  • Fingerprinting or logging — Content must be identifiable even if metadata is stripped

A single layer is not sufficient. All three are required.

The compliance checklist

Layer 1: Provenance metadata (C2PA)

  • AI-generated images include a C2PA manifest
  • The manifest is cryptographically signed
  • The manifest records: generator model, organization, timestamp
  • The signature can be verified by a third party

Layer 2: Watermarking

  • Images contain an invisible watermark (LSB steganography or equivalent)
  • The watermark survives JPEG compression
  • The watermark survives basic resizing and cropping
  • The watermark can be detected by your verification endpoint

Layer 3: Fingerprinting/logging

  • A perceptual hash of each image is stored in a registry
  • The image can be identified even if all metadata is stripped
  • The registry is accessible via a verification API

Process and documentation

  • Your compliance implementation is documented
  • You have an audit trail of when and how content was signed
  • You can produce compliance evidence on request by regulators
  • Your DPA covers the data processing involved in signing

What happens if you're not compliant?

Fines under the EU AI Act can reach €15 million or 3% of global annual turnover, whichever is higher. Enforcement begins August 2, 2026.

The fastest path to compliance

Implementing all three layers yourself requires deep expertise in C2PA spec implementation, steganography, and perceptual hashing. The typical implementation timeline is 2-4 months for a team that knows what they're doing.

OpenCorpo handles all three layers in a single API call — under 200ms per image. You can be compliant in an afternoon.

OpenCorpo is a C2PA Conformance Program member. Our implementation is tested against the C2PA conformance suite.
