Abstract:
With the rapid development of modern medical technology and the dramatic increase in the amount of medical data, traditional centralized medical information management is facing many challenges. In recent years blockchain, which is a peer-to-peer distributed database, has been increasingly accepted and adopted by different industries and use cases. Key areas of healthcare blockchain applications include electronic medical record (EMR) management, medical device supply chain management, remote condition monitoring, insurance claims and personal health data (PHD) management, among others. Even so, there are a number of challenges in applying blockchain concepts to healthcare and its data, including interoperability, data security privacy, scalability, TPS and so on. While these challenges may hinder the development of blockchain in healthcare scenarios, they can be improved with existing technologies In this paper, we propose a blockchain-based healthcare operations management framework that is combined with the Interplanetary File System (IPFS) for managing EMRs, protects data privacy through a distributed approach while ensuring that this medical ledger is tamper-proof. Doctors act as full nodes, patients can participate in network maintenance either as light nodes or as full nodes, and the hospital acts as the endpoint database of data, i.e., the IPFS node, which saves the arithmetic power of nodes and allows the data stored in the hospitals and departments to be shared with the other organizations that have uploaded the data. Therefore, the integration of blockchain and zero-knowledge proof proposed in this paper helps to protect data privacy and is efficient, better scalable, and more throughput.
摘要:
随着现代医学技术的飞速发展和医疗数据量的急剧增加,传统的集中式医疗信息管理面临诸多挑战。近年来,区块链,这是一个点对点的分布式数据库,越来越被不同行业和用例所接受和采用。医疗保健区块链应用的关键领域包括电子病历(EMR)管理,医疗器械供应链管理,远程状态监测,保险索赔和个人健康数据(PHD)管理,在其他人中。即便如此,将区块链概念应用于医疗保健及其数据存在许多挑战,包括互操作性,数据安全隐私,可扩展性,TPS等等。虽然这些挑战可能会阻碍区块链在医疗保健场景中的发展,它们可以用现有技术进行改进,我们提出了一个基于区块链的医疗保健运营管理框架,该框架与星际文件系统(IPFS)相结合,用于管理EMR,通过分布式方法保护数据隐私,同时确保此医疗分类帐防篡改。医生充当完整的节点,患者可以作为轻节点或完整节点参与网络维护,医院充当数据的端点数据库,即,IPFS节点,这节省了节点的算术能力,并允许存储在医院和部门中的数据与上传数据的其他组织共享。因此,本文提出的区块链和零知识证明的集成有助于保护数据隐私,更好的可扩展性,和更多的吞吐量。
