When the signal is in the noise: Exploiting Diffix's Sticky Noise

Understand

Anonymized data is highly valuable to both businesses and researchers.

• A large body of research has however shown the strong limits of the de-identification release-and-forget model, where data is anonymized and shared.
• This has led to the development of privacy-preserving query-based systems.
• Based on the idea of "sticky noise", Diffix has been recently proposed as a novel query-based mechanism satisfying alone the EU Article~29 Working Party's definition of anonymization.
