Use-based Privacy

Abstract: Modern applications collect, generate, and share vast quantities of data, and much of this data is private, sensitive, or subject to legal restrictions. The current approach to handling data privacy—notice and consent—is inadequate for today's privacy requirements. Use-based privacy is an alternative philosophy that stems from the observation that most privacy concerns are about uses, not accesses. In this talk, I will describe our investigation into the feasibility of use-based privacy as a technical solution to the challenges of data privacy. This work includes a study of existing user privacy preferences and a new policy language designed for expressing use-based privacy, and I will discuss our experience building a system that uses Intel's Software Guard Extensions (SGX) as a root of trust for enforcing use-based privacy in decentralized, distributed systems. I will also talk about my ongoing interests in technology-assisted teaching at scale and in improving participation and diversity in computer science.
