Comment Period Extended
(November 14, 2025) The public comment period has been extended through December 5, 2025.
NIST is pleased to release the initial public draft of Internal Report (IR) 8588, A Community-Driven Differential Privacy Deployment Registry. This draft proposes a NIST-hosted database of community-contributed descriptions of differential privacy (DP) deployments.
DP is a mathematical definition of privacy, and DP deployments are computer systems that add calibrated noise to data to protect the privacy of individuals. Since DP is being used at scale in many contexts, a database of implementation descriptions is an important step to establish guidelines and best practices for its application.
The quality of the NIST-hosted repository proposed in IR 8588 is maintained through a public working group. This draft describes the data schema, working group function, and other important considerations.
The public comment period is open through November 14, 2025 December 5, 2025. See the publication details for a copy of the draft and instructions for submitting comments.
NIST invites the public to comment on the plan and especially welcomes contributions that will help maximize the value of the DP Registry.
