Medicine tracing system based on RFID and block chain and implementation method

Abstract

The invention belongs to the technical field of commerce, such as shopping or electronic commerce, and discloses a medicine tracing system based on RFID and a block chain and an implementation methodthereof, and the system comprises the steps: automatically inputting data of a medicine production, transportation and sales process into the block chain through RFID read-write equipment, and storingthe data; enabling the blockchain platform to adopt the form of an alliance chain, and allow a plurality of participants to jointly participate in the establishment and maintenance of an account book. The block chain network adopts a multi-channel architecture to isolate account book information in different channels to realize coarse-grained privacy protection, and further adopts an encryption algorithm and a permission management strategy in the channels to realize fine-grained privacy protection. The drug tracing system based on the RFID and the block chain is used for tracing drugs. The defects of data source reliability and data centralized storage of an existing drug enterprise self-built tracing system or a third-party tracing platform are overcome, and publicity and transparency of the drug tracing system are achieved.

Description

technical field [0001] The present invention belongs to business, such as shopping or e-commerce technical field, and in particular relates to a drug traceability system and implementation method based on RFID and block chain. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: drug traceability is of great significance to the drug safety of patients. The main reason why the former State Food and Drug Administration stopped the drug electronic supervision system is that the information security that pharmaceutical companies are concerned about cannot be guaranteed. At present, there are two modes of drug traceability, one is that pharmaceutical companies build their own drug traceability system, and the other is to use a third-party traceability platform. The drug traceability platform built by pharmaceutical companies is mainly designed for the clerks of pharmaceutical retail terminals. Consumers who purchase drugs ...

AI Technical Summary

Problems solved by technology

Regardless of whether the pharmaceutical company builds itself or uses a third-party platform, the traditional drug traceability system uses a centralized storage model. In this mode, since pharmaceutical companies and third-party platforms are stakeholders in the drug supply chain, when When storing information to their own detriment, these companies may tamper with the database to make drug traceability meaningless

[0003] To sum up, the problem with existing technologies is that both pharmaceutical companies and third-party platforms are stakeholders in the drug supply chain. When storing information is not good for them, companies may tamper with the database to make drug traceability impossible. significance

The data entered into the barcode using barcode technology cannot be updated, the information capacity is small, and the traceability information is mainly concentrated on drug production information, lack of drug circulation and sales information, and there is a risk of drugs being dropped midway; the centralized data storage mode cannot guarantee the storage of system information security and immutability
