Communication-Efficient Laplace Mechanism for Differential Privacy via Random Quantization
Ali Moradi Shahmiri, Chih Wei Ling, Cheuk Ting Li
We propose the first method that realizes the Laplace mechanism exactly (i.e., a Laplace noise is added to the data) that requires only a finite amount of communication (whereas th…

Vector Quantization with Error Uniformly Distributed over an Arbitrary Set
Chih Wei Ling, Cheuk Ting Li
For uniform scalar quantization, the error distribution is approximately a uniform distribution over an interval (which is also a 1-dimensional ball). Nevertheless, for lattice vec…
