基于区块链技术的医药可追溯系统的研究

Research on medical traceability system based on blockchain technology

国内医药的溯源服务存在追溯信息完整性不足、追溯范围覆盖不全、追究责任的主体确认困难等问题。本文针对上述问题,在对国内部分医药市场需求调研和分析各领域与追溯产业结合的案例基础上,提出一种基于区块链技术,实现医药全程可追溯的方法。同时,利用区块链的公开透明,不可篡改,无需信任和去中心等优势,构建了基于区块链的溯源系统;结合RFID电子标签等技术,解决了传统溯源过分依赖中心以及容易篡改数据等痛点问题,实现了医药的采购、生产、加工到流通的全程可追踪溯源的功能。本文研究的主要内容有利于医药追溯的发展,助力于提升国内的药物质量,避免假药、劣药事件的频频发生。

The traceability service of domestic medicine has the problems such as insufficient information integrity,incomplete coverage of traceability,and difficulty in identifying the subject of accountability.In view of the above problems,based on the case of market demand research and analysis of some domestic medicines combined with traceability industry,a method based on blockchain technology is proposed to realize the full traceability of medicine.At the same time,taking advantage of the openness and transparency of the blockchain,non-tampering,no trust and decentralization,etc.,a traceability system based on the blockchain is constructed combined with RFID electronic tags and other technologies,solving the problems of traditional traceability about excessive dependence on the center and tamper with data.The system achieves the procurement of medicine,production,processing to circulation of the entire traceability function.This system is conducive to the development of medicine retrospectively and could help to improve the quality of domestic drugs to avoid the frequent occurrence of counterfeit drugs,bad drugs incidents.
