It is based on the application of controlled noise at the interface between the server that stores and processes the data, and the data consumers.

This paper investigates the utility gain of using Iterative Bayesian Update (IBU) for private discrete distribution estimation using data obfuscated with Locally Differentially Private (LDP) mechanisms.

However, as the collection of multiple sensitive information becomes more prevalent across various industries, collecting a single sensitive attribute under LDP may not be sufficient.

As shown in the results, differentially private deep learning models trained under gradient or input perturbation achieve nearly the same performance as non-private deep learning models, with loss in performance varying between $0. 57\%$ to $2. 8\%$.

The objective of this thesis is thus two-fold: O$_1$) To improve the utility and privacy in multiple frequency estimates under LDP guarantees, which is fundamental to statistical learning.

Regarding the latter, we introduce the use of past rehabilitation data to build more realistic data-driven identified models.
