TikTok EU data localization enforcement — Project Clover + EUR 345M GDPR fine
Date: 2023-09
Affected: TikTok / ByteDance — EUR 345M fine + EUR 12B data localization investment; all AI companies processing EU personal data with non-EU infrastructure
Attack vector: rce
Category: real-world
Severity: Critical

The Irish Data Protection Commission fined TikTok EUR 345 million for GDPR violations related to children's data processing and transparency failures. Separately, ongoing EU regulatory pressure over TikTok's data transfers to China led to the mandatory implementation of Project Clover — a EUR 12 billion program to localize European user data in European data centers. While not AI-specific, the case directly impacts TikTok's recommendation algorithm (an AI system) because training data, user interaction data, and model inference data must now be processed within EU borders. The enforcement established that AI systems processing EU personal data must comply with data localization requirements, and that the AI recommendation engine cannot be separated from the data governance obligations. This is the defining case for DSGAI20 — data localization violations in AI systems.

Impact: EUR 345M fine; EUR 12B infrastructure investment for data localization; establishes that AI recommendation systems cannot bypass data localization requirements; precedent for all AI companies with cross-border data flows

Mitigations:
Data residency assessment for all AI training and inference data
Data localization by design — process personal data in the jurisdiction of origin
Transfer impact assessments (TIA) for any cross-border AI data flow
Separate training pipelines per jurisdiction where required by law
