Implementation of Industrial Internet data traceability technology based on blockchain
To solve the problem of large amount of data and complex data relationships in Industrial Internet,a data traceability method based on blockchain and PROV-DM model is proposed.This method uses the PROV-DM model to record traceability infor-mation,which can describe multiple data relationships in Industrial Internet;The storage structure is blockchain blockchain,which can reduce the amount of data computation in the traceability query process and improve the efficiency of traceability queries;Each blockchain is equipped with a smart contract that effectively ensures encryption and decryption rates.Through experiments,the data traceability method can complete multiple functions such as data traceability record and traceability query,encrypt and decrypt tracea-bility information with large amount of data at a high speed,have high traceability query efficiency and large throughput,and basically meet the data traceability requirements of Industrial Internet.Therefore,the data traceability method based on blockchain and PROV-DM model has certain value in the practical application of Industrial Internet.
