100 Re-identification Attack Pain Points

Anonymization is not a binary state — it is a fragile equilibrium that collapses under adversarial pressure. 4 spatiotemporal points identify 95% of people, 15 attributes re-identify 99.98%. 10 pain points per category across the full attack surface.

This page is part of the anonym.community PII pain point research project, which documents 1,478 distinct pain points generated by 98 irreducible structural drivers across 14 research tracks and 240 jurisdictions. The research synthesizes privacy legislation analysis, enforcement decisions, technical literature, and real-world case studies to explain why PII privacy problems persist despite technological and regulatory advances. The complete research corpus is freely available at anonym.community.
