论文摘要
电子健康记录（EHR）管理系统需要在交换健康信息时采用有效的技术。当前的管理方法通常会面临可能使病历存储解决方案暴露于常见安全攻击向量的风险。但是，面向医疗保健的区块链解决方案可以提供分散，匿名且安全的EHR处理方法。本文介绍了使用分布式分类账技术和身份混音器（IDEMIX）的隐私EHR管理解决方案Prehealth。本文描述了使用HyperLeDger Fabric的权限区块链框架的概念验证实现。提出的解决方案能够有效地存储患者记录，同时提供匿名性和无链接性。实验性能评估结果证明了该计划对现实量表部署的效率和可行性。
Electronic health record (EHR) management systems require the adoption of effective technologies when health information is being exchanged. Current management approaches often face risks that may expose medical record storage solutions to common security attack vectors. However, healthcare-oriented blockchain solutions can provide a decentralized, anonymous and secure EHR handling approach. This paper presents PREHEALTH, a privacy-preserving EHR management solution that uses distributed ledger technology and an Identity Mixer (Idemix). The paper describes a proof-of-concept implementation that uses the Hyperledger Fabric's permissioned blockchain framework. The proposed solution is able to store patient records effectively whilst providing anonymity and unlinkability. Experimental performance evaluation results demonstrate the scheme's efficiency and feasibility for real-world scale deployment.
