PhD Candidate Orooji Recognized for Paper on Privacy vs. Data Utility

Orooji Marmar headshotBATON ROUGE, LA – Marmar Orooji, a PhD candidate in engineering science with a concentration in information technology engineering, was recently given a finalist award in the Institute of Industrial and Systems Engineers (IISE) Data Analytics & Information Systems Division’s 2018 Best Student Paper Competition for her paper, “Improving Suppression to Reduce Disclosure Risk and Enhance Data Utility.

Her advisor on the paper was Associate Professor of Industrial Engineering Gerry Knapp.

The award was presented at the 2018 IISE Annual Conference in Orlando.

In the paper, Orooji and Knapp examine the trade-off between preserving privacy and data utility and state that the more changes made to the confidential dataset to reduce disclosure risk, the more information the data loses and the less data utility preserved. They propose an improved suppression method that reduces the disclosure risk and enhances the data utility by targeting the highest risk records and keeping the others intact. The effectiveness of this approach is documented through an experiment on a real-world confidential dataset.

In addition, the LSU IISE Chapter was awarded a Gold Award at the annual conference in the 2018 Chapter Recognition Program. The chapter is led by Student President Camille Giarrusso, an industrial engineering senior from Covington, La., and Knapp, the faculty advisor.
