Method and system for generating trusted logistics voucher based on block chain

Abstract

According to the method and system for generating the logistics voucher based on the block chain provided by the invention, the seal application is approved according to the application information submitted by the seal application, so that the supervision of seal records from the seal node and the approval node of the block chain is ensured; according to the invention, by generating the seal record data packet, acquiring the complete logistics voucher after seal and the application information submitted by the corresponding seal user, and storing the seal record data packet in the logistics voucher block chain, the chaining evidence storage is realized, and the authenticity of the seal record data in each link is ensured; through the block chain, automation of logistics vouchers from collection to online management is realized, corresponding transaction data can be queried in the block chain according to the feedback transaction hash, backtracking of historical data is realized, authenticity and legality of the data are ensured, a user can query a complete voucher chain, and the user experience is improved. And the authenticity and credibility of the logistics voucher can trace back the seal using record and content of each time of seal completeness.

Description

technical field [0001] The invention relates to the technical field of logistics and transportation, and in particular, to a method and system for generating a trusted logistics certificate based on a block chain. Background technique [0002] Logistics will generate various documents in the process of transportation, storage, loading and unloading, handling, etc., and the logistics documents need to be updated and saved in real time according to the change of logistics order status. The existing logistics mainly transmit the execution of logistics through paper documents. With the increase of the logistics business volume, the logistics documents and the corresponding logistics status are prone to errors. In order to make the logistics documents easy to manage, it is usually necessary to set up a logistics document management system. [0003] The existing logistics document management system mainly collects the paper logistics documents generated in the offline business man...

AI Technical Summary

Problems solved by technology

[0004] (1) It is difficult to guarantee the authenticity of logistics documents, and it is difficult to effectively supervise the forgery and counterfeiting in the offline manual entry process, which will damage the credibility of logistics documents or vouchers;

[0005] (2) Due to the huge volume of logistics business, after the accident, it is difficult to trace all the logistics documents generated in the logistics business only manually, it is difficult to trace all the relevant data generated in the accident, and it is difficult to identify the logistics documents in the historical data or the authenticity of the certificate;

[0006] (3) With the growth of the logistics business volume and the changes in the business status of the transportation, transshipment, storage and other processes in the logistics process, the efficiency of manual entry of logistics vouchers will decrease accordingly, resulting in labor costs, time costs and corresponding data Storage costs will increase dramatically

[0007] The above defects lead to the existing logistics document management system is not conducive to the management of logistics documents
