The Power of the Hybrid Model for Mean Estimation [PDF]

open access: yesProceedings on Privacy Enhancing Technologies, 2020
Abstract We explore the power of the hybrid model of differential privacy (DP), in which some users desire the guarantees of the local model of DP and others are content with receiving the trusted-curator model guarantees. In particular, we study the utility of hybrid model estimators that compute the mean of arbitrary realvalued ...
