Pharmaceutical information tamper-proof traceability management system based on mobile block chain

Abstract

The invention relates to a pharmaceutical information tamper-proof traceability management system based on a mobile block chain, characterized by comprising a block chain module, a pharmaceutical barcode input module, a query module, a certificate center module, a mobile device terminal for connecting the block chain module through a mobile block chain API, a database module for reading and storing data and a front-end technical module for realizing data visualization. The pharmaceutical bar code input module encrypts the privacy data of the drug and the enterprise through the public key andstores the read bar code data into the block chain module through the first intelligent contract, and the query module reads the privacy and 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 data, and guarantees the transparency of the drug supply chain. The mobile block chain API not only enables the mobile device to participate in the network governance and transaction information verification as a node in the block chain network, but also can access thedata on the storage chain, thereby improving the convenience.

Description

technical field [0001] The invention relates to a drug information anti-tampering traceability management system based on a mobile block chain. Background technique [0002] blockchain technology. The core technical characteristics of blockchain technology are "decentralization" and "de-trust". As a distributed general ledger technology, a smart contract basic platform, and a new distributed computing paradigm, it can effectively build programmable currency and a programmable society. Moreover, it can well guarantee information tamper-proof and information certification. Therefore, blockchain technology is bound to have a profound impact on anti-tampering of drug information and traceability of supply chain information. 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...

AI Technical Summary

Problems solved by technology

1) A lot of time and energy consumption: to realize the blockchain technology can only be realized on the computer side and to participate in the governance of the network, it needs to be online all the time, so it consumes more energy and time

2) Inconvenient to carry: Since it is impossible for regulatory authorities, enterprises or the public to carry a computer all the time, and it is very inconvenient to go out with a computer, so if the blockchain technology can only be implemented on the computer side, it cannot be used anytime, anywhere Participate in the blockchain network to verify the transaction process, etc., so it is very inconvenient

3) Inconvenient query: The traditional blockchain technology can only query data through the computer terminal, and cannot track drug information in real time, but the mobile blockchain can not only directly access the data on the storage chain, but also through Participate in the consensus mechanism to obtain rights and interests

[0007] 2. The current drug supply chain system is not perfect, and there are the following shortcomings: 1) Lack of trust: the information of each subject in the supply chain is stored 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 the information is easy to be artificially modified, so there is no trust between the parties

2) Leakage of private data: According to the law, companies need to provide drug data to the competent authorities and also need to disclose it to the outside world. However, because corporate data may involve commercial secrets, companies are worried about the issue of private data leakage

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

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
