The Privacy Blanket of the Shuffle Model Advances in Cryptology ...

Webb1 juni 2024 · ArXiv. Shuffle model of differential privacy is a novel distributed privacy model based on a combination of local privacy mechanisms and a secure shuffler. It has been shown that the additional randomisation provided by the shuffler improves privacy bounds compared to the purely local mechanisms. Accounting tight bounds, however, is … Webb20 juni 2024 · The privacy blanket of the shuffle model. abs/1903.02837, 2024. Amplification by shuffling: From local to central differential privacy via anonymity. Jan 2024; 2468-2479; Úlfar Erlingsson; Webb\\ The Shuffle Model is an adaptation of the Local Model, with the randomization step exactly the same, but afterwards a “shuffler” is added to perform a random permutation of the data. The level of noise required for the same privacy guarantee is reduced, by making it impossible for the central entity or an adversary to tell which data belongs to which user. harvard university free furniture
