[0002] With the rapid development of e-commerce and global supply chains, the logistics industry is facing the challenge of massive data transmission. Logistics data not only contains basic information such as the location and status of goods, but also sensitive information such as customer privacy and trade secrets. Its security is directly related to corporate operations and user trust. Traditional logistics data transmission methods are vulnerable to security threats such as hacker attacks and information leakage, and an efficient and intelligent security monitoring system is urgently needed.

[0003] Chinese Patent Publication No. CN116938607A discloses a data transmission method and device for smart logistics, which includes the following steps: responding to a logistics delivery request, selecting a destination logistics site based on a preset logistics site map; executing a preset work order encryption process based on the logistics delivery request and the destination logistics site, encrypting and generating a logistics delivery work order; and sending the logistics delivery work order to the destination logistics site. This application is based on the work order encryption process, and encrypts and generates the logistics delivery work order through encryption operations of different dimensions and different levels, thereby ensuring that the data transmission of the logistics delivery work order has good confidentiality, effectively avoiding information leakage, and improving the level of information security; it can be seen that the invention only encrypts and transmits logistics data, does not extract data and judge the transmission environment, and has the problem of low security in the transmission of logistics information.
