History

Historical Context

Building on the 1995 EU Data Protection Directive, the European Commission adopted the General Data Protection Regulation, which took effect on May 25 2018 and unified privacy rules across member states. The GDPR’s strong enforcement has led firms such as Anthropic to embed compliance tools like invisible watermarks in AI outputs to meet emerging EU requirements.
