EU rules require detectable machine-readable marks

The Commission describes a technical marking duty for covered AI-generated or altered content.

Evidence explainer

What this establishes

The duty goes beyond a visible notice. Providers must make covered outputs technically detectable as generated or altered.

Why it matters: Technical provenance is a distinct policy instrument from user-facing deepfake labels.

Limits and context: The Commission FAQ and final legal text determine scope, exceptions and the treatment of systems already on the market.

Require covered providers to attach detectable technical provenance markers to synthetic or materially altered content.

Article 50 establishes transparency duties for specified AI interactions and synthetic or manipulated content.

The EU’s Article 50 transparency duties became applicable as enforcement powers expanded.
