Registry ideation, development, and evaluation

  • Dwork, C., Kohli, N., & Mulligan, D. (2019). Differential Privacy in Practice: Expose Your Epsilons!. Journal of Privacy and Confidentiality, 9(2). This paper proposed a registry for differential privacy deployments, including an initial set of attributes per deployment each entry should contain. They also interviewed practitioners about how they deploy differential privacy.

  • Nanayakkara, P., Ghazi, E., & Vadhan, S. (2025). Making Privacy Public: Toward a Differential Privacy Deployment Registry. arXiv preprint arXiv:2509.13509. This research paper developed a schema for each deployment and contributed to the design of the registry interface. The existing schema and interface draws substantially on the designs from this paper. They also conducted an exploratory user study of an interactive registry prototype with practitioners.

(2025) A Community-Driven Differential Privacy Deployment Registry. NIST Internal Report 8588, U.S. Department of Commerce. Initial Public Draft. This white paper offers a vision and governance proposal for the registry. NIST offered a public comment period on the proposal in late 2025, and the group is currently (as of March 2026) in the process of revising the paper and responding to the comments.

  • …your paper here! The registry is a community effort, and research studies on uptake of the registry are encouraged.
