A drug information management method and system based on a block chain

Abstract

The invention discloses a drug information management method and system based on a block chain, and the method comprises the steps: carrying out the role management and identity authentication of a drug supply chain participating enterprise, and determining the drug supply chain as a blockchain node; After the original medicine information and the enterprise identity information are preprocessed,determining medicine tracing information; Releasing the drug tracing information on a block chain, so that each block chain node has a data backup corresponding to the drug tracing information; Constructing a drug circulation transaction on the block chain based on a preset transaction model, and updating the drug tracing information recorded by the block chain; And in response to a drug information query request, carrying out transaction query on the block chain, and analyzing the queried transaction to obtain the actual circulation information of the drug. According to the invention, peer-to-peer participation and privacy information of all enterprises are ensured, and the drug information tracking efficiency and accuracy are improved.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a block chain-based drug information management method and system. Background technique [0002] With the development of society and the advancement of science and technology, people pay more attention to healthy life and use drugs more and more cautiously. Patients or drug dealers expect to be able to track and obtain all the distribution information of corresponding drugs. [0003] The traditional drug information management system usually maintains or operates a drug information management platform or drug information traceability platform by a commercial company. Enterprises in the supply chain upload drug-related information to the platform, and then the platform summarizes and provides Inquiry and other services. This mode of operation has the following problems: [0004] The original information of all drugs is uploaded to the platform, and the ope...

Problems solved by technology

[0004] The original information of all drugs is uploaded to the platform, and the operator of the platform can obtain and modify this information. On the one hand, it will damage the commercial privacy and interests of related companies, and on the other hand, it is difficult to guarantee the authenticity of the data; and the centralized platform resists attacks. The ability of the platform is relatively weak, and it relies heavily on the technical strength of the platform operator; the data interface provided in the platform is limited, which is not conducive to the integration of relevant data in the platform into its own enterprise resource planning system by enterprises

It can be seen that the traditional drug information management system cannot guarantee the peer-to-peer participation and privacy of all enterprises, nor can it meet the accuracy and efficiency of actual drug tracking information
