Guidelines for Evaluating Differential Privacy Guarantees

A supplier says its analytics product offers differential privacy. What should you ask before relying on that claim? NIST explains how the guarantee is defined, what choices affect its strength, and how implementation decisions can change the protection people actually receive.

Inside the whitepaper

• Identify whose data the guarantee protects and what counts as a change to the dataset.
• Understand how privacy parameters and repeated analyses affect the overall guarantee.
• Review the complete data pipeline for implementation risks that a mathematical proof alone cannot address.
