基于区块链的医疗数据共享模型研究
A Medical Data Sharing Model via Blockchain
摘要
Abstract
According to the status quo of medical industry,verification,storage and synchronization of clinical data are difficult,therefore,clinic data sharing between institutions become a challenging task.There are many restrictions in data access and sharing for patients,doctors and even researchers,which results in a high cost of both resources and time for authority authentication and verification.To solve this problem,we propose a blockchain-based medical data sharing model,with advantages of decentralization,high security,collective maintenance and tamper resistance.We discuss the critical principles and components of this model in detail.Furthermore,we improve the consensus mechanism so as to better match different types of medical institutions for a more convenient,secure and faster data sharing.In addition,the merits and impacts of this model are presented and analyzed by comparisons in terms of existing issues in medical data.关键词
