STAR: Distributed Secret Sharing for Private Threshold Aggregation Reporting (original) (raw)

Abstract

Servers often need to collect data from clients that can be privacy- sensitive if the server is able to associate the collected data with a particular user. In this document we describe STAR, an efficient and secure threshold aggregation protocol for collecting measurements from clients by an untrusted aggregation server, while maintaining K-anonymity guarantees.
