# Differential privacy pyramid

## Appears In

                        - NIST Offers Draft Guidance on Evaluating a Privacy Protection Technique for the AI Era
                        - National Institute of Standards and Technology

Evaluating any claim to differential protection requires examining every component of the differential privacy pyramid. Its top level contains the most direct measures of privacy guarantees, including epsilon, which is a numerical value of how strong the privacy guarantee is. The middle level includes factors that can undermine a differential privacy guarantee, such as lack of sufficient security, and the bottom level includes underlying factors, such as the data collection process. The ability for each component of the pyramid to protect privacy depends on the components below it.
