基于区块链技术的公共数字阅读平台

Public digital reading platform based on blockchain technology

针对现有数宇阅读平台普遗存在的阅读资源分市数乱、隐私数船保护函乏、版权保护力度不足等问题,设计并实现了一个基于区块链技术的公共数字阅该平台。基于开源框架Hyperledger Fabric搭建底层区块链网络,利用星际文件系统IPFS并结合代理重加密PRE技术,形成了黄源文件“链上索引,链下存储”的存储模式,在保证数据安全的前提下扩展了区块链网络的存储能力。同时,利用SimHash算法实现对阅读黄源的重复性检测,为作品版权保护授供了技术支持。经过详细的功能测试及安全性,隐私性分析,验证了该方案的可行性和有效性,为解决数字阅读平台目前存在的问题提供了一种可行思路。

The existing digital reading platforms generally have problems such as scattered distributionof reading resources,lack of privacy data protection and insufficient copyright protection.To addressthese problems,a public digital reading platform based on blockchain technology is proposed in thispaper.The underlying blockchain network was built based on Hyperledger Fabric.A storage modelof"on-chain indexing and off-chain storage"was formed by using the interplanetary file system(IPFS)cooperated with the proxy re encryption(PRE)technique.The storage capacity of blockchainnetwork was expanded on the premise of ensuring data security.In addition,the original test ofreading resources was achieved through SimHash algorithm,providing technical support for thecopyright protection.Through detailed functional testing,security analysis and privacy analysis,thefeasibility and effectiveness of the scheme were verified.Therefore,a feasible way to solve thecurrent problems of digital reading platforms is provided.
