Vaccine traceability method and system based on alliance chain

Abstract

The invention provides vaccine tracing method and system based on alliance chain. The method includes: 1) creation step: respectively creating a blockchain service network and an application layer, wherein the blockchain service network is used for executing a contract method called by signature transaction and performing data synchronization to acquire real block data; 2) submitting step: synchronizing the real block data to the application layer by using the blockchain service network, calling an entity login contract to login an entity account by means of the application layer, and submitting vaccine environment record and vaccine circulation record through the blockchain service network; 3) tracing step: submitting retrieval requirement to the blockchain service network by means of theapplication layer, and according to the retrieval requirement, tracing and acquiring the vaccine environment record and vaccine circulation record by means of the blockchain service network. The method and system can be integrated with a vaccine tracing system which is established in the prior art and satisfies industrial standards, and can effectively acquire the vaccine environment record and vaccine circulation record.

Description

Technical field [0001] The invention belongs to the technical field of block chains, and specifically relates to a vaccine traceability method and system based on alliance chains. Background technique [0002] Article 10 of the Vaccine Administration Law of the People’s Republic of China clearly stipulates the main responsibility of vaccine marketing license holders to establish vaccine electronic traceability systems. However, the current traceability system is usually unilaterally used by vaccine marketing license holders with traditional information Technically established, the data generated by it cannot verify the authenticity of the source and the integrity of the content. [0003] There are existing technologies for applying blockchain technology to the traceability of products (including drugs), which realizes that the source of the data and the integrity of the data can be verified. However, in the field of vaccine traceability, there are still the following issues to be r...

AI Technical Summary

Problems solved by technology

[0004] 1. Most traceability methods cannot be integrated with the currently established vaccine traceability systems that meet industry standards, and require new naming rules for product traceability codes or a new vaccine traceability system;

[0005] 2. The basic product data (such as manufacturer, license, product specification, etc.) is mixed with the circulation data, resulting in the processing of a large amount of repetitive product basic information, and most of the product basic information is unnecessary;

[0006] 3. Lack of scalable design for blockchain network processing capabilities, it is difficult to support the scale of vaccine traceability data nationwide;

[0007] 4. The credibility of the vaccine circulation history depends on the query on the chain and the query efficiency is low, which brings inconvenience to the verification work;

[0008] 5. The circulation process of the vaccine involves the relationship between parent and child packaging. The traceability method in the prior art does not accommodate this relationship, so it is impossible to form a complete circulation history of child packaging accompanied by parent packaging;

[0009] 6. Most vaccines are required to be kept within a strict refrigerated temperature range during the whole process of circulation. During this process, the environmental tracking equipment will continuously generate temperature / location information. There are two limitations in the traceability method of the existing technology: one is that the refrigerated unit environment has not been realized The association between records and the vaccine circulation process; second, it is difficult to cope with the high-frequency and large-scale data pressure of environmental records
