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.
