Blockchain-based trusted computing in social network

MIT Media Lab employed blockchain to describe a decentralized personal data management system (i.e. Decentralizing Privacy) that ensures users own and control their data without authentication from a third party. In this paper, we employ a better encryption algorithm from NTT Service Evolution Laboratory to enforce the “Decentralizing Privacy”. Instead of using Proof-of-Work (PoW) for protection, we employ Proof-of-Credibility Score to improve the pervious system and analyzed attack situations.
