Research And Implementation Of Controllable Sharing Mechanism Of Fine-grained Logistics Data

With the development of cooperation and communication between different enterprises in the logistics field,data sharing has become an inevitable phenomenon in the logistics industry.However,for the data owner,some data are important data related to the core interests.Once they are leaked in the sharing process,they will face significant losses.Therefore,the sharing of logistics data among collaborators will face the problems of data disclosure and privacy protection.With the emergence of new technologies such as industrial Internet identity resolution technology and blockchain,new ideas and technical support have been provided to solve this problem.This paper studies data sharing in the field of logistics,and proposes a finegrained access control mechanism for logistics data sharing based on identification analysis technology and blockchain.The main work and innovation are summarized as follows:(1)A fine-grained logistics data identification analysis method based on identification analysis technology is proposed.This paper fully analyzes the demand for sharing data in the logistics field,and then classifies the data attributes to form fine-grained data according to the attributes and access requirements of the logistics data.In addition,the functional application of the industrial Internet identity resolution system is studied,including the functions of identity registration,identity management and identity resolution for data.And research the identification scheme and coding rules for the fine-grained data generated by the sharing requirements,realize the identification of the fine-grained data,and share the data in the form of identification code,so as to keep the data locally and protect the data sovereignty.(2)A controllable sharing method of logistics data based on extended attribute encryption algorithm and blockchain is proposed.Research blockchain technology with decentralized,traceable,tamper-proof and other characteristics,and realize identity authentication and controllable sharing of logistics data through blockchain.At the same time,the application of CP-ABE technology based on password policy in logistics business collaboration scenarios is studied,and the original attribute encryption algorithm is extended to realize the reuse of access policy attributes,reduce the operation time during encryption,and improve efficiency.Then conduct controllable sharing research on data attributes and visitor attributes,and use attribute encryption technology to encrypt shared data,so as to achieve both data encryption protection and access control in the process of data sharing.(3)A controllable sharing mechanism of fine-grained logistics data is designed.On the basis of the above two research contents,and in combination with the actual situation of data sharing requirements and restrictions in the logistics field,we will study the controllable sharing mechanism of logistics fine-grained data combining identification analysis and blockchain.The relevant experimental tests of Handle system,blockchain and attribute encryption algorithm in identity resolution technology have been carried out to verify the feasibility of the mechanism.This mechanism improves the credibility of user access control,enhances the data security in the process of logistics data sharing,and provides a new method of secure data sharing for partners with data sharing needs in the logistics field.
