A pair of Bitcoin entrepreneurs and the MIT Media Lab has revealed a prototype for a system called Enigma, a decentralized cloud platform with guaranteed privacy. Enigma allows users to store, share, and analyze personal data without it being fully revealed to any party. Powered by the blockchain, Enigma aims to be a secure, multi-party computation. The team at MIT has already developed a prototype for Enigma, which is based on a highly optimized version of secure multi-party computation, guaranteed by a verifiable secret-sharing scheme. MIT Media Labs’ whitepaper says:
“For storage, we use a modified distributed hashtable for holding secret-shared data. An external blockchain is utilized as the controller of the network, manages access control, identities and serves as a tamper-proof log of events. Security deposits and fees incentivize operation, correctness and fairness of the system…
Similar to Bitcoin, Enigma removes the need for a trusted third party, enabling autonomous control of personal data. For the first time, users can share their data with cryptographic guarantees regarding their privacy.”…
