Collecting Data while Preserving Individuals' Privacy: A Case Study

Alexis Bonnecaze and Robert Rolland

Abstract

Several companies exploit medical data to better understand medication consumption patterns. Their analyses are useful to various health actors in order to enhance health care management. In this article, we focus on a configuration which allows a network of pharmacies to forward medical data to a private company in order to construct a database. Pharmacies must operate in full compliance with legal requirements in terms of confidentiality and privacy. We show that our solution fulfills all the requirements. Our work leads us to introduce the concept of generalized discrete logarithm problem which is proven to be as hard as the discrete logarithm problem.
