面向机场行李全流程跟踪的改进PoA共识机制区块链系统研究

Research on an Improved PoA Consensus Mechanism Blockchain System for Airport Luggage Full Process Tracking

智慧机场建设是机场高质量发展的核心之一。目前,客运行李的错装、漏装、迟交、行李破损丢失时各方责任难以划分以及行李全流程跟踪数据公信度较低等是目前亟待解决的问题。传统方法大多依赖于人工和监控设备来追踪,极大地耗费人力物力,同时存在数据盲区以及数据被篡改的可能性,公信度较低。对此,设计基于区块链技术的机场行李全流程跟踪系统,采集多个关键节点的行李数据信息并上传至区块链中;在此基础上,提出一种基于PoA共识算法的改进模型,保证数据的真实有效性和高公信度,解决系统自治、责任划分和赔付问题,并提高网络的安全性和可维护性,为行李跟踪数据的溯源和防篡改等智慧机场建设相关研究提供了新思路。

Smart airport construction is one of the core elements of high-quality airport development.But Misloaded,missed,delayed,difficult to divide responsibilities when baggage is damaged and lost of passengers’checked baggage,and the credibility of baggage tracking data in the whole process is one of the problems that need to be solved urgently,most of the traditional solutions rely on manual and monitoring equipment to track,which greatly consumes manpower and material resources,and there are data blind spots and the possibility of data tampering,the credibility is low.Therefore,design a whole process tracking method of airport baggage based on blockchain technology,Collect baggage data information from multiple key nodes and upload it to the blockchain;Design incentive mechanism to encourage all parties to actively participate in the data link;At the same time,an improved model based on PoA consensus algorithm is proposed to improve the security and maintainability of the network,so as to provide a reference for the traceability and tamper proof of baggage tracking data and Smart airport construction.
