Optimal Privacy-Utility Trade-Offs in LDP: Functional and Geometric Perspectives
Seung-Hyun Nam, Hyun-Young Park, Si-Hyeon Lee
Local differential privacy (LDP) has emerged as a gold-standard framework for privacy-preserving data analysis. However, characterizing the optimal privacy-utility trade-off (PUT)…
Fundamental Limit of Discrete Distribution Estimation under Utility-Optimized Local Differential Privacy
Sun-Moon Yoon, Hyun-Young Park, Seung-Hyun Nam +1
We study the problem of discrete distribution estimation under utility-optimized local differential privacy (ULDP), which enforces local differential privacy (LDP) on sensitive dat…
Exactly Optimal and Communication-Efficient Private Estimation via Block Designs
Hyun-Young Park, Seung-Hyun Nam, Si-Hyeon Lee
In this paper, we propose a new class of local differential privacy (LDP) schemes based on combinatorial block designs for discrete distribution estimation. This class not only rec…
