Supplementary Material: From Privacy-Utility Trade-offs to Policies

Note: This record is currently fully anonymized to comply with double-blind peer review requirements. Author metadata and affiliations will be updated upon paper acceptance. This dataset and document serve as the supplementary material for the research paper: "From Privacy-Utility Trade-offs to Policies: Optimized Anonymization Recommendations for Data Trustees in Data Spaces". It contains extended evaluation results, metric tables, and visual failure mode illustrations for 11 spatial anonymization methods evaluated on a real-world dataset of 2,147 forest cadastral parcels. Furthermore, it includes the extended adversarial threat model results (Homogeneity, Background Knowledge, and Satellite Correlation scores) and the parameter sensitivity analysis for H3 grid and Geohash resolutions.
