Multi-Freq-LDPy: Multiple Frequency Estimation Under Local Differential Privacy in Python. (arXiv:2205.02648v2 [cs.CR] UPDATED)

This paper introduces the multi-freq-ldpy Python package for multiple
frequency estimation under Local Differential Privacy (LDP) guarantees. LDP is
a gold standard for achieving local privacy with several real-world
implementations by big tech companies such as Google, Apple, and Microsoft. The
primary application of LDP is frequency (or histogram) estimation, in which the
aggregator estimates the number of times each value has been reported. The
presented package provides an easy-to-use and fast implementation of
state-of-the-art solutions and LDP protocols for …
