Description:
The increasing prevalence of data-driven decision making requires robust mechanisms to protect sensitive information while allowing its utility for collective benefit. Differential Privacy (DP) offers a rigorous framework for achieving strong privacy guarantees. This tutorial will explore how differential privacy can be leveraged to facilitate secure and privacy-preserving information sharing in various contexts. We will dive into the fundamental concepts of DP and discuss its application in scenarios where data are acquired, shared, aggregated, or processed to derive collective insights, ensuring individual contributions remain private.
The tutorial will cover recent advances in applying DP to practical challenges in information exchange, including methods for private estimation, learning, and inference, as well as incentive compatible and privacy-preserving mechanisms for optimal data sharing and acquisition. Attendees will gain an understanding of the trade-offs involved in designing DP mechanisms for real-world systems and learn about the techniques that enable effective information flow while mitigating privacy risks. Our discussion will highlight the importance of careful design to balance privacy with the goals of data utility, sharing, and collaborative knowledge generation, as well as open problems and research questions of interest to the WINE community in this space.
