Design Of Asset Management System Based On RFID And Blockchain

Asset management is the identification,counting,and monitoring of items(assets)with high value in the enterprise.A large group of companies has a large variety of assets,and the assets are scattered in the internal departments of various subsidiaries,and even outside the enterprise.Therefore,asset management,asset transfer and other management business processes in asset management are complex and the information is abundant.The current asset management methods used today are prone to the following problems:(1)multi-party collaboration of complex businesses leads to manual waste and low efficiency;(2)security issues such as asset loss are difficult to trace and confirm;(3)opaque grasp of asset information leads to difficulties in asset reorganization and distribution,resulting in asset waste.This thesis analyzes the business of the asset management system and proposes the application of RFID technology and blockchain technology as key technologies for asset management to achieve the traceability and anti-counterfeiting functions of asset management.The main contributions of the asset management system based on RFID and block introduced in this thesis are:(1)Architecture design of asset management system.The system uses RFID and blockchain technology to design an RFID-based asset management web system and an asset management blockchain storage model.It not only uses the characteristics of RFID to improve the efficiency of asset management,reduces labor costs,but also makes use of the unavailability of blockchain.Tampering provides a strong guarantee for asset traceability and anti-counterfeiting.(2)Design of asset management blockchain storage model.The system adds RFID storage to the blockchain model to further ensure the security of block data.At the same time,this article designs a hybrid dual-chain block structure technology,and separately designs a consensus mechanism and a block structure for the dual chain.Innovatively introduced both transaction-based and account-based block structures into the unified block system.Finally,the three-layer verification mechanism design of RFID,main chain,and side chain storage was designed to further improve the traceability,anti-counterfeiting,andresponsibility positioning performance of asset management.(3)Design the RFID tag data writing mechanism.As assets are scattered inside and outside the enterprise,and the value is high,this article combines the RFID data of the assets with the resume information,and applies the idea of blockchain to design a label writing mechanism with clear responsibility and strong anti-counterfeiting and traceability.Based on this,an asset management system is designed and implemented,including: RFID reader application interface and terminal interaction design;reader interface and client,handheld terminal interface call and functional interaction design;RFID data security design.
