基于雾计算的区块链病历管理架构设计与应用

Design and Application of Blockchain Medical Record Management Architecture Based on Fog Computing

雾计算是云计算的延伸概念,可以使计算和存储功能更接近应用程序和医疗信息数据源。提出了一种基于雾计算的区块链医疗数据管理架构,医疗数据所有者的元数据存储在私有区块链上,支持搜索和防篡改功能,并允许雾节点以分布式方式执行授权过程。案例研究表明,与其他方法相比,本研究所提出架构可以缩短患者医疗数据访问时间,满足可靠性和互操作性要求,为病历资料管理理论和实际应用提供借鉴。

Fog computing,one of the extended concepts of cloud computing that brings computing and storage functions closer to applications and medical information sources.A blockchain medical data management architecture based on fog computing is proposed,where the metadata of the medical data owner is stored on a private blockchain to support search and tamper-proof functions,and to allow fog nodes to perform authorization processes in a distributed manner.The case study showed that compared with other methods,the proposed architecture can shorten the access time of patients'medical data,meet the requirements of reliability and interoperability,and provide reference for the theory and practical application of medical record management.
