摘要
随着当前数字经济的发展,数据共享和保护成为推动经济发展的必然选择。然而数据在共享过程中容易出现数据篡改、数据盗用、监管难度大等问题。文章提出基于区块链的数字内容共享和安全监管方案。区块链具有防篡改、可追溯、去中心化的特点,能够有效解决数据篡改和盗用问题。为了解决数字内容分享系统中的监管问题,文章提出了内容链和监管链的双链模型,增加了数据管理的灵活性和安全性,其中监管链对系统中的交易进行全程监督,从而构建责任可追责系统。IPFS提供了一个弱冗余、高性能的存储方式。该方案采用IPFS作为数字内容存储模块,将IPFS与区块链技术相结合从而保证数字内容的安全存储和访问控制。最后,实验分析和评估表明该方案是可行的。
With the development of the current digital economy,data sharing and protection are inevitable choices to promote the development of the economy.However,data tampering,data misappropriation,difficult supervision and other problems are easy to occur in the process of data sharing.This paper proposes a blockchain-based digital content sharing and security supervision scheme.Blockchain has the characteristics of antitampering,traceability,and decentralization,which can effectively prevent data tampering and theft.In order to solve the problem of supervision in the digital content sharing system,this paper proposes a double-chain model of content chain and supervision chain,which increases the flexibility and security of data management.The supervision chain supervises the transactions in the system throughout the whole process,so as to build a responsible accountability system.IPFS provides a weakly redundant,high-performance storage method.The system uses IPFS as the digital content storage module,and the combination of IPFS and blockchain technology ensures the safe storage and access control of digital content.Finally,the experimental analysis and evaluation show that the scheme is feasible.
