Abstract or Description

The work demonstrates a real-world system using a multiparty computation protocol that performs an accurate unduplicated accounting across homeless programs with guarantees of privacy protection for clients of domestic violence shelters. This paper describes the goals of the project, the regulatory environment and policy goals as well as technical details and results from third-party real-world experiments. The described solution is a new multi-party protocol ("PrivaMix") that works in real-time.
