Combining Differential Privacy and Secure Multiparty Computation
Martin Pettai and Peeter Laud
Abstract: We consider how to perform privacy-preserving analyses on private data from different data providers and containing personal information of many different individuals. We combine differential privacy and secret sharing in the same system to protect the privacy of both the data providers and the individuals. We have implemented a prototype of this combination and the overhead of adding differential privacy to secret sharing is small enough to be usable in practice.
