U-DPAP: Utility-aware Efficient Range Counting on Privacy-preserving Spatial Data Federation

Summary: U-DPAP: first DP-only privacy-preserving scheme for range counting in spatial data federations (no SMC). Proposes grouping-based perturbation and representative-silo selection to optimize privacy-utility and efficiency-utility, with formal guarantees and empirical gains.
