Topic: Optimising Twin Uniform Distribution for Multiplicative Noise Data Masking
Abstract:
Multiplicative noise masking is a well-known method to perturb data for privacy protection purpose. Twin uniform distribution has been introduced in the literature as a distribution for multiplicative noise, given the simplicity in its mathematical form and the ability to provide good value protection without sacrificing statistical utility. We further explore the impact of various distribution parameters on the performances of privacy protection and utility loss when multiplying twin uniform noise for data masking. An approach to optimise the multiplicative noise scheme with twin unform noise distribution is proposed. We apply the optimisation algorithm to a real accounts payable dataset, and conclude that it yields good results for both privacy and utility.
Biography:
Pauline is a lecturer in Statistics in the University of Wollongong, Australia. Before that, she had worked as statistical consultant in the Australian National University. Her recent research interests are the area of data privacy.
