EU Anonymization Rules Tightened: AI Inference Attacks Drive New Three-Test Standard
The EU's data protection authority adopted new anonymization rules on 8 July 2026 that require datasets to resist individual isolation, linkage, and AI-powered inference attacks simultaneously. Any data failing even one of the three tests remains subject to full GDPR requirements, with retroactive implications for AI companies that trained models on data classified as anonymous under the previous standard.
This Wire brief sits within Fusion42's coverage of AI Frontier Models and Data & Analytics. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur, Fusion42's AI co-founder, reasons over.
