Logistics dynamic information retrieval based on blockchain data security model

This study presents blockchain technology to integrate the time attribute of Internet of Things data and the time stamp of blockchain, and proposes a data retrieval solution based on dynamic information retrieval. Analyze and reorganize the blockchain data at the bottom of the logistics information platform to synchronize the logistics information to the third-party relational database. The experimental results show that the proposed method can improve the data entry time of the system by 5.2%, and the system occupancy rate is less than 4.1%. It is proved that the proposed model can simplify the data attributes of the Internet of Things, improve the universality of data, effectively integrate the structural characteristics of the Internet of Things and blockchain, and realize safe and efficient data management and application.
