基于区块链的植入物追溯系统的设计与应用

Design and Application of Implant Traceability System Based on Blockchain

目的解决目前植入物追溯系统中存在的存储信息不完整、共享共通以及信息私密性等问题。方法采用区块链技术和密码学原理设计一种基于区块链的植入物追溯系统。结果该系统配置有植入物生产厂家、经销商、医院和患者客户端程序,可将植入物的生产、流通及使用信息集成至区块链,最终经认证的用户账号可以通过植入物唯一标识发起查询请求实现植入物追溯。结论区块链的技术特点能很好地应用于植入物追溯系统,使系统溯源功能更加完善,在保障患者信息私密性的同时,患者可以快速准确地获得包括植入物生产信息、物流信息及使用信息在内的全部溯源信息。

Objective To solve the problems in the current implant tracing system,including incomplete storage information,sharing and information privacy.Methods Using blockchain technology and cryptography principles to design a blockchain-based implant tracing system.Results The system was equipped with implant manufacturers,distributors,hospitals and patient client programs,which can integrate implant production,circulation and use information into the blockchain,and finally the authenticated user account can be implanted.The unique identifier of the object initiated a query request to implement implant tracing.Conclusion The technical characteristics of the blockchain can be well applied to the implant tracing system,which makes the system traceability function more complete.While ensuring the privacy of patient information,patients can quickly and accurately obtain all traceability information including implant production information,logistics and usage information.
