Research And Implementation Of Code-sharing Flight Management System Based On Blockchain

With the development of the air transport industry worldwide,the "code-sharing" flight operation model has been born,that is,one carrier uses other airline codes on flights by agreement,or two carriers share the same airline on the same flight by agreement.Company code,so a passenger on a certain flight may buy a ticket from more than one airline.At present,the operation mode of code sharing has become the most popular way of cooperation in the global air transport industry.The management of code-share flight information is a distributed system involving flight information of multiple airlines.However,since there is no authoritative organization with centralized control and mutual recognition for certification,prevarication,wrangling and disputes occur from time to time.The emerging blockchain technology provides a new way to solve such problems.This paper analyzes and studies the operation mechanism and existing problems of blockchain technology,smart contract technology,and code-sharing flights.Based on the alliance chain,a new solution for code-sharing flight information management is proposed to avoid disputes in the information exchange of multiple airlines..In view of the current problems in the exchange and authentication of code-sharing flight information,an improved code-sharing flight system scheme based on blockchain is proposed to achieve the goal of tamper-proof and traceable information exchange between peer-to-peer enterprises.It analyzes and abstracts the management function of code-sharing flights,and integrates the traditional management module and the Hyperledger Fabric blockchain authentication module based on the alliance chain in the process of information exchange between different airlines.This solution can increase the support of blockchain nodes through controllable and limited modifications on the basis of ensuring the functions of the original system.At the same time,in view of the difficulty of verifying business data changes between distributed systems,a message verification mechanism of four interactions is proposed to abstract and standardize the information related to business changes in the improved system.Before and after sending and receiving a message,it interacts with the blockchain system once,and the blockchain is used to ensure the correct transmission and processing of the message.During the message uploading process,for the consideration of data privacy and data consistency,the summary of transaction data is selected to be uploaded to the chain.And implemented an improved code-sharing flight information management system based on blockchain.In addition to the management functions of the traditional code-sharing flight management system,the improved system also has chain code management,user management,and blockchain transactions of the blockchain system.verification and other functions.Experiments and system trial operation show that the improvement scheme is safe and operable,and the traditional system can be completed on the chain after a certain amount of transformation,and achieves the goal of anti-tampering and traceability under the information management and existing operating mechanism,which is of great importance.value and broad application prospects.
