Differential privacy (DP) is the leading framework for publishing useful statistics with rigorous privacy guarantees. This Dagstuhl Seminar concentrates on DP for data sharing and statistical data release, where the goal is to approximate well-defined functions of data (e.g., counts, histograms, marginals, and time series), for example via synthetic data (artificial datasets that preserve statistical properties). This focus is of interest for public agencies and regulators, as well as other organizations that need to share information derived from datasets while respecting privacy requirements.
Major deployments of DP, such as the U.S. Census Bureau's 2020 TopDown system, and EU regulatory drivers (notably the 2022 Digital Markets Act on sharing search-related data with anonymisation) raise questions that are both theoretical and urgent in areas such as: tight privacy accounting under composition; adaptive (workload-aware) mechanisms for structured releases; reconciliation under policy invariants; principled utility metrics; and streaming DP for continuous publication. This seminar will be research-oriented, deepening theory while learning from and being motivated by practice. It aims to bring together researchers in design and analysis of differentially private algorithms with practitioners from statistical agencies and industry.
