Data Trusted Sharing Platform Based on Hyperledger Fabric
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.
