sMPCの参考リンクまとめ

The Jana system provides a single encrypted database whose data is processed by MPC engines so as to service the users’ queries. A key aspect of the Jana system is how it integrates MPC, differential privacy, and searchable encryption in a seamless manner. The Sharemind system provides a shared database, whose goal is to enable the joint analysis and sharing of data from multiple sources without revealing any information about the shared records. Partisia has also conducted experiments of secure statistical data processing using MPC enabling banks to share customer data, without compromising the customers’ privacy

For example, in the medical data use-case from above, it is likely that each peer in the system will belong to some hospital, and hence will have some data that it can see but the other peers cannot.

For example we can use the blockchain facilities for identity management and communication (or even use an existing im- plementation of a consensus protocol to implement a broadcast channel that may be needed in the protocol).
