    Topic: Optimising Twin Uniform Distribution for Multiplicative Noise Data Masking 


    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.


    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.



    After the talk we will be holding a dinner at The Golden Drum restaurant, Shop 1/14 Childers St, Canberra. (Golden Drum | Canberra ACT | Facebook). If you are interested in attending the dinner, please let me know by 5pm Monday 25 March by entering your details at SSA Canberra Branch dinner attendance sheet or contacting me (; 0407 916 868). Please regard this as a firm commitment, not just an intention. For withdrawals after the deadline, please remove your name from the sheet and phone or text me (0407 916 868).

    NOTE: We are offering discounts to SSA Early Career and Student members who attend dinner! Specifically, dinners will be a fixed charge of $10 for student members and $20 for early career members. Others will pay their share of the bill, after SSA applies a small subsidy. Typically this is $30-$40. Please bring cash if possible."
