Electronic medical records (EMRs) are extremely private data in the medical industry. Clinicians use the patient data that the EMR stores to quickly assess a patient's status and save diagnostic information. In the conventional medical model, it is easy for duplicate exams, medical resource waste, or the loss of medical records to happen when a patient is transferred between several medical facilities due to problems with data sharing and exchange, inadequate data privacy, security, confidentiality, and difficulties with data traceability. This paper recommends a Hyperledger Fabric-based strategy to promote the exchange of EMR models. With the use of Hyperledger Fabric, EMR stakeholders can be brought into the channel to facilitate data sharing. Attribute-based access control (ABAC) allows users to design the data access control policy, and the data access control may improve security. Any record stored in the blockchain can be viewed using the Hyperledger Fabric feature and it cannot be altered or destroyed, ensuring data traceability. Through proxy re-encryption, which makes sure that the data is not leaked during data exchange, data secrecy can be ensured. A module for medical tokens has now been added. Many foreign medical institutions currently use the medical token system, and the system described in this paper can use the tokens to pay for some medical expenses. The tokens are obtained by the patient's initiative to share their EMR with the medical institution for research, which is how many foreign medical institutions currently use the medical token mechanism. This paradigm can encourage the growth of medical data by enabling stakeholders to collaborate and share EMR trust.
电子病历(EMR)是医疗行业中极其私密的数据。临床医生使用电子病历存储的患者数据来快速评估患者状况并保存诊断信息。在传统医疗模式下,当患者因数据共享与交换问题、数据隐私性不足、安全性与保密性欠佳以及数据可追溯性困难等原因在多个医疗机构之间转诊时,重复检查、医疗资源浪费或病历丢失的情况很容易发生。本文推荐一种基于超级账本织物(Hyperledger Fabric)的策略来促进电子病历模型的交换。通过使用超级账本织物,可将电子病历利益相关者引入通道以促进数据共享。基于属性的访问控制(ABAC)允许用户设计数据访问控制策略,并且数据访问控制可提高安全性。使用超级账本织物功能可查看存储在区块链中的任何记录,且该记录无法被更改或销毁,从而确保数据可追溯性。通过代理重加密可确保数据保密性,它能保证在数据交换期间数据不会泄露。现在已添加了医疗令牌模块。目前许多国外医疗机构使用医疗令牌系统,本文所述系统可使用令牌支付部分医疗费用。令牌由患者主动将其电子病历与医疗机构共享用于研究而获得,这也是目前许多国外医疗机构使用医疗令牌机制的方式。这种模式可通过促使利益相关者协作与共享电子病历信任来推动医疗数据的增长。
