摘要
现今社会上数据的规模和种类变得越来越庞大和多样化,如何安全可信地共享异构数据资源成为了亟待解决的问题.为实现大数据的可信互联,提出基于Hyperledger Fabric的数据可信共享平台.首先,针对数据异源异构的问题,定义了数据架构的转换规则;然后,以数据提供方和数据需求方之间的数据共享全过程为导向,提出了数据可信追溯机制,保证了数据共享的真实性和完整性;此外,文中设计了一种数据处理即服务的数据共享框架,在确保数据可信的前提下,支撑数据调用、数据训练和数据匹配操作.通过对执行效率和智能合约性能进行验证分析,证明了本平台的有效性和实用性.
Abstract
With the increasing scale and variety of big data in today's society,how to securely and trustfully share heterogeneous data has become an urgent problem to be solved.In order to achieve trusted interconnection of big data,a data trusted sharing platform based on Hyperledger Fabric is proposed.First of all,the conversion rules of data architecture are defined to solve the problem of heter-ogeneous data sources.Second,guided by the whole process of data sharing between data providers and data requesters,this paper pro-poses a data trustworthy traceability mechanism to ensure the authenticity and integrity of data sharing.In addition,a data-processing-as-a-service data sharing framework is developed based on smart contract,which supports data invoking,data training and data matc-hing on the premise of ensuring the trustworthiness of data.Finally,the effectiveness and practicality of this platform is proved by eval-uating the execution efficiency and smart contract performance.
