The communication cost of security and privacy in federated frequency estimation
Wei-Ning Chen, Ayfer Özgür, Graham Cormode +1
We consider the federated frequency estimation problem, where each user holds a private item from a size- domain and a server aims to estimate the empirical frequency (i.e…
The Poisson binomial mechanism for secure and private federated learning
Wei-Ning Chen, Ayfer Özgür, Peter Kairouz
We introduce the Poisson Binomial mechanism (PBM), a discrete differential privacy mechanism for distributed mean estimation (DME) with applications to federated learning and analy…
The Fundamental Price of Secure Aggregation in Differentially Private Federated Learning
Wei-Ning Chen, Christopher A. Choquette-Choo, Peter Kairouz +1
We consider the problem of training a dimensional model with distributed differential privacy (DP) where secure aggregation (SecAgg) is used to ensure that the server only sees…
