Research on Distributed Network Data Storage Security based on block chain

Abstract

With the advantages of mass storage and easy expansion, distributed storage architecture has become the main way of user big data storage, but the confidentiality, integrity and availability of data are facing serious challenges.As a new distributed shared ledger, blockchain technology has become an important technology to ensure data security since it was proposed by virtue of its characteristics of decentralization, tamper-proof and anonymity.Based on blockchain technology, this paper studies the key technology and application scheme design of data distributed storage, and verifies the feasibility of the scheme.
