Practical Private Set Operation via Secret Sharing for Lightweight Clients

This research proposes a new method for private set operations (PSO, techniques that let organizations securely compare or combine datasets without revealing private information) that reduces the computational burden on client devices. The approach uses secret sharing (splitting data into pieces so no single party can see the whole picture) to allow servers to do most of the work while clients can stay offline, making it practical for large-scale collaborative research across institutions like hospitals.
