Enabling a Privacy-Preserving Data Life Cycle
with Lightweight Secure Computation

Many of the most exciting developments in technology are premised on clever use of massive datasets. At the same time, today's practices for collecting, processing, and sharing data bring profound risks — the theft of individuals' medical records, businesses' financial data, and governments' secrets. The goal of this project is to develop new, lightweight privacy-protecting tools that let individuals, businesses, and governments reap the benefits of large datasets while providing strong, cryptographic privacy guarantees for user data.

Our systems operate in a setting with a small number of infrastructure servers and many millions of clients. The servers gather, process, and share user data while revealing as little as possible — to themselves and to system users — about any individual's data, and privacy holds as long as at least one server is honest.
