Abstract

This paper assesses the usefulness of a proposed multiplicative perturbation method by contrasting the statistical efficiency achieved in point hypothesis testing of simple proportions with that of the differentially private aggregated Laplace mechanism. This efficiency is evaluated by obtaining an analytical expression that determines the sample size required for protected data to retain a given significance level and power.
