Orchard: Differentially Private Analytics at Scale

Edo Roth, Hengchu Zhang, Andreas Haeberlen, Benjamin C. Pierce
2020 USENIX Symposium on Operating Systems Design and Implementation  
Orchard accomplishes this by rewriting queries into a distributed protocol that can be executed efficiently at scale, using cryptographic primitives.  ...  This paper presents Orchard, a system that can answer queries about sensitive data that is held by millions of user devices, with strong differential privacy guarantees.  ...  Conclusion Prior to Orchard, it may have seemed that running differentially private queries at scale required either making compromises (on privacy, accuracy, or trust) or custom-building a cryptographic  ...
