Abstract

The purpose of this document is to provide a high level understanding of the trade-offs that are required when designing and deploying differentially private systems (e.g., privacy, utility, number of trusted parties). Its goal is to enable a less-expert reviewer in their analysis of differentially private systems, and to suggest issues and dimensions to consider when reviewing a system.
