Sharemind MPC supports several different SMC schemes called protection domains, but the SUNFISH platform uses the shared3p protection domain, which stands for 3-out-of-3 secret sharing with passive security. Sharemind uses MPC to analyse data that was not accessible before. Sharemind resolves trust issues by removing centralised control and unwanted data access points.

This framework implements a frontend for a variety of backends but its own backend only uses three-party semi-honest computation with an honest majority [BLW08]. It also allowstheuseofABYandFRESCOasbackendwhiletheproprietary backend is not freely available. The inner product example takes Sharemind MPC frameworks, which limit MPC steps to two or three parties, but adding support for further frameworks requires only modest effort.

The Sharemind system uses three servers to hold the shares of secret val-ues. In Sharemind terminology, these servers are data miners. The miners are connected with each other over the network using secure channels and use secure MPC protocols to evaluate a function on the secret shared data. Sharemind uses additive secret sharing scheme in the model of Sharemind supports different secure com-puting protocols abstracted as protection domains [6].

Recently MPC has developed from a purely theoretical research field into a multitude of practical deployments. An overview of numerous MPC applications is given by Archer et al. [Arc+18]. Sugar Beet Auction The classic example of a problem where MPC can be Sharemind MPC (Multi-Party Computation) End-to-end data protection with accountability In a service powered by Sharemind, data owners encrypt their data on premises and upload them to Sharemind.

A good overview of the recent advances can be found in [6][4], especially in the full versions.

Sharemind is a privacy technology enabling new data-driven services and business models. Achieve big data privacy and process databases you could not access before.

The system is secure against a Secure multi-party computation (also known as secure computation, multi-party computation (MPC), or privacy-preserving computation) is a subfield of cryptography with the goal of creating methods for parties to jointly compute a function over their inputs while keeping those inputs private.
