Anthropic Puts Hidden Watermarks on Claude Text Under New EU Rules
Anthropic embeds invisible watermarks in Claude text worldwide to meet EU transparency rules, with marks designed to survive copy-paste and some edits.
- Anthropic implemented machine-readable watermarks for New Claude models to tag AI-generated content worldwide, ensuring transparency across products like Claude Code and Claude Cowork.
- The initiative aligns with the European Union Code of Practice and transparency requirements under the Act, which Anthropic signed to standardize AI-generated content tracking.
- Anthropic utilizes invisible signals for Text, while Files carry signed provenance metadata based on the C2PA standard to record Content Provenance and Authenticity.
- Platforms including AWS, Google Cloud, and Microsoft Foundry now incorporate these markings, providing a machine-readable identity that helps third parties detect Claude-generated material.
- Detection reliability remains limited for both Text and Files, as Anthropic cautions that editing or Short passages can compromise the signals and undermine definitive authorship proof.
