Intelligent Cloud Cabinet Management Platform Based On Blockchain

The Internet has promoted the network process of the logistics industry,and cloud cabinet emerged at the historic moment in the pursuit of efficient and convenient distribution methods in the logistics industry.The terminal distribution form with Cloud Cabinet as the main body not only ease the operation pressure of terminal delivery stations,but also improve the efficiency of logistics operations.Of course,this win-win distribution method that logistics benefits user experience also have some problems,especially the following disadvantages brought by the system implementation architecture characterized by a typical central server: 1)hosting of the central server The way of the system user's private information make the data flow of the system users' private information difficult to be visible to the system user himself,as well as access control,which leads to the lack of his own information control right and it is difficult to avoid the leakage and illegal abuse of private information;2)Lack of credible information The traceability mechanism make it difficult to weigh responsibilities openly and transparently among logistics participants when business disputes occur.To this end,this is blockchain technology to provide a smart cloud cabinet management platform architecture,and design and implement the actual needs of cloud cabinet products of related companies.The main work is as follows:(1)Aiming at the characteristics of the current smart cloud cabinet management platform architecture and business,especially its requirements in terms of information security and user experience,by introducing permission chain technology in the blockchain,a DBPoS consensus mechanism oriented to the permission chain is proposed.This consensus mechanism on the basis of the DPoS consensus mechanism,a PBFT algorithm is used as the core resolution mechanism.In the voting phase resolution mechanism,a multi-factor random seed algorithm is introduced to compete for witness nodes,thereby solving the issue of fairness in DPoS elections.The feedback mechanism improves the enthusiasm of the nodes to vote and the efficiency of finding the wrong nodes.Experimental analysis shows that the consensus mechanism is feasible in the smart cloud cabinet management platform.(2)Aiming at the issues of system user privacy protection and access control rights,by introducing blockchain technology and combining the principle of identity autonomy SSI,a users' self-management BUCM model is proposed.This model uses authentication nodes,control function permission chains,and the three major parts of the data storage service are users' registration authentication and access control to ensure user privacy and security and access control.Based on this,a mechanism of accountability based on Merkel's key spanning tree is proposed to account for users who absconded illegally.Comparative analysis shows that the model satisfies the requirements of reliability and security.(3)On the basis of the above work,combined with the DBPoS consensus mechanism and BUCM model,through the integration of blockchain technology,the smart cloud cabinet management platform prototype system based on the blockchain is designed and implemented,which satisfies users' autonomous management and various logs.Information is efficiently accessed on the chain.Its information also provides credible evidence for blame blame in the event of a dispute.
