The distributed discrete gaussian mechanism for federated learning with secure aggregation

P Kairouz, Z Liu, T Steinke - International Conference on …, 2021 - proceedings.mlr.press
We consider training models on private data that are distributed across user devices. To
ensure privacy, we add on-device noise and use secure aggregation so that only the noisy …

The fundamental price of secure aggregation in differentially private federated learning

WN Chen, CAC Choo, P Kairouz… - … on Machine Learning, 2022 - proceedings.mlr.press
We consider the problem of training a $ d $ dimensional model with distributed differential

Scenario-based Adaptations of Differential Privacy: A Technical Survey

Y Zhao, JT Du, J Chen - ACM Computing Surveys, 2024 - dl.acm.org
Differential privacy has been a de facto privacy standard in defining privacy and handling
privacy preservation. It has had great success in scenarios of local data privacy and …

Differential privacy in the shuffle model: A survey of separations

A Cheu - arXiv preprint arXiv:2107.11839, 2021 - arxiv.org
Differential privacy is often studied in one of two models. In the central model, a single
analyzer has the responsibility of performing a privacy-preserving computation on data. But …

Federated learning is a collaborative machine learning framework where a global model is
trained by different organizations under the privacy restrictions. Promising as it is, privacy …

Flame: Differentially private federated learning in the shuffle model

R Liu, Y Cao, H Chen, R Guo… - Proceedings of the AAAI …, 2021 - ojs.aaai.org
Federated Learning (FL) is a promising machine learning paradigm that enables the

On the power of multiple anonymous messages: Frequency estimation and selection in the shuffle model of differential privacy

B Ghazi, N Golowich, R Kumar, R Pagh… - … Conference on the …, 2021 - Springer
It is well-known that general secure multi-party computation can in principle be applied to
implement differentially private mechanisms over distributed data with utility matching the …

User-level differentially private learning via correlated sampling

B Ghazi, R Kumar… - Advances in Neural …, 2021 - proceedings.neurips.cc
Most works in learning with differential privacy (DP) have focused on the setting where each
user has a single sample. In this work, we consider the setting where each user holds $ m …

Distributed, private, sparse histograms in the two-server model

J Bell, A Gascon, B Ghazi, R Kumar… - Proceedings of the …, 2022 - dl.acm.org
We consider the computation of sparse,(ε, ϑ)-differentially private~(DP) histograms in the
two-server model of secure multi-party computation~(MPC), which has recently gained …
