Episode notes
Legal Status Depends On Re-Identification Risk
- Regulators judge anonymity by the risk of re-identification, not by the process used to create data.
- Under GDPR, if re-identification is reasonably likely the synthetic set is treated as personal data.
The Three Legal Attack Vectors
- Regulators evaluate singling out, linkability, and inference when deciding anonymity.
- Failure on any of these dimensions can reclassify synthetic data as personal data under law.
Memorization Enables Membership Inference
- Generative models can memorize training examples, enabling membership inference attacks that reveal whether an individual's record was used.
- Overfitting to unique records makes synthetic outputs vulnerable to privacy breaches.
