基于区块链的个人健康记录分布式框架研究

Study on Blockchain-based Distributed Framework of Personal Health Records

利用区块链技术构建个人健康记录分布式框架,分析采用区块链存储医疗大数据存在的问题并提出相应改进措施,包括采取开放式电子健康记录规范(openEHR)标准,在区块链中仅存储主索引和查询位置等。阐述架构设计及安全性,指出其有助于实现可信任的个人健康记录访问。

The distributed framework of Personal Health Records(PHR)has been built by utilizing blockchain technology.The paper analyzes the problems with storing healthcare big data by adopting blockchain technology and comes up with corresponding measures to achieve improvement,including adopting openEHR standard,only storing prime index and location query in the blockchain,etc.It also elaborates on the architecture design and security of the framework,points out that such a framework can facilitate the reliable access to PHR.
