Since it was introduced in 2006 by theoretical computer scientists Dwork, McSherry, Nissim, and Smith, differential privacy has become the leading framework for ensuring that individual-level information is not leaked through statistical releases or machine learning models built from sensitive datasets. In addition to a rich theoretical literature, differential privacy has also started to make the transition to practice, with large-scale applications by the US Census Bureau and technology companies like Google, Apple, Microsoft, and Meta. After giving some of this background, I will describe OpenDP, a community effort to advance the practice of differential privacy that we have been building over the past few years. In particular, OpenDP is developing a trustworthy and open-source suite of differential privacy tools that can be easily adopted by custodians of sensitive data to make it available for research and exploration in the public interest. Finally, I will give a taste of some of the intriguing research questions that this effort to bring differential privacy to practice has raised.
