Differential privacy
Differential privacy (DP) is a wide-ranging paradigm for statistically-guaranteed data privacy. The Privacy Engineering Team at the Wikimedia Foundation is currently exploring various uses for DP at WMF. This page (and its subpages) intend to document project statuses, design decisions, and potential future directions.
