Abstract

Public services collect massive volumes of data to fulfill their missions. These data fuel the generation of regional, national, and international statistics across various sectors. However, their immense potential remains largely untapped due to strict and legitimate privacy regulations. In this context, Lomas is a novel open-source platform designed to realize the full potential of the data held by public administrations. It enables authorized users, such as approved researchers and government analysts, to execute algorithms on confidential datasets without directly accessing the data. The Lomas platform is designed to operate within a trusted computing environment, such as governmental IT infrastructure. Authorized users access the platform remotely to submit their algorithms for execution on private datasets. Lomas executes these algorithms without revealing the data to the user and returns the results protected by Differential Privacy, a framework that introduces controlled noise to the results, rendering any attempt to extract identifiable information unreliable. Differential Privacy allows for the mathematical quantification and control of the risk of disclosure while allowing for a complete transparency regarding how data is protected and utilized. The contributions of this project will significantly transform how data held by public services are used, unlocking valuable insights from previously inaccessible data. Lomas empowers research, informing policy development, e.g., public health interventions, and driving innovation across sectors, all while upholding the highest data confidentiality standards.
