A tamper-proof traceability management system for pharmaceutical information based on block chain

Abstract

The invention relates to a drug information tamper-proof traceability management system based on block chain, characterized in that it comprises a block chain module, a drug bar code input module forreading the drug bar code, a query module for querying drug information data, a database module for reading and storing the data queried by the inquiry module into a database, a front-end technical module for visualizing the data in the database module, and a certificate center module for providing a public key and a certificate to a drug bar code input module and a private key and a certificate to the inquiry module; The drug bar code input module encrypts the privacy data of the drug and the enterprise through the public key and stores the read bar code data into the block chain module through the first intelligent contract. The query module reads the privacy data and the public data in the block chain module through the private key and the second intelligent contract. The invention realizes the tracking of the drug supply chain and the visualization of the information data, and ensures the transparency of the whole drug supply chain.

Description

technical field [0001] The invention relates to a block chain-based drug information tamper-proof traceability management system. Background technique [0002] blockchain technology. 2015 is known as the first year of the world's blockchain. In October 2015, searches with blockchain technology as the keyword continued to top the list. 2016 is the first year of blockchain in China, and 2017 is the first year of blockchain from laboratory to application. Blockchain technology is still developing rapidly. Blockchain technology is attracting attention and interest from all walks of life. Among them, blockchain technology is the most popular in the financial field, but with continuous development, blockchain technology needs to continue to expand into various fields, so as to continuously use blockchain technology to solve data privacy and protection issues in various fields . At present, the development of blockchain technology is still concentrated in the financial field, ...

AI Technical Summary

Problems solved by technology

[0007] 1) Lack of trust: the information of each subject in the supply chain is stored separately in the subject itself, the information between the subjects is not transparent enough, and the interests of cooperative enterprises are less considered, which leads to uneven distribution of interests among all parties and slow information transmission, so information is easily leaked Human modification, so there is no trust between the various subjects

[0008] 2) Leakage of private data: According to the law, companies need to provide drug data to the competent authority and also need to announce it to the outside world. However, because the company's data may involve commercial secrets, companies are worried about the problem of private data leakage

[0009] 3) Difficulty in regulatory traceability: due to the lack of mutual trust, once disputes or quality problems (such as counterfeit drugs on the market, expired drugs, etc.) occur, the efficiency of finding the cause of the problem is low, it is difficult to obtain evidence, and it takes a lot of manpower and material resources

[0010] 4) It is difficult to distinguish the authenticity of drugs: There are many uncertainties in the entire supply chain system of drugs, and users, hospitals or clinics have no idea about the quality of the drugs they receive and whether they are produced by the manufacturer , can only be judged by humans, so there is no guarantee that the obtained drugs are real and effective
