个人健康记录 (PHR) 是每个患者的私人且重要的资产。迄今为止，已经介绍了许多关于管理和组织 PHR 的各个方面的工作。然而，PHR 在紧急情况下的作用仍存在不确定的问题。在传统的紧急访问系统中，患者无法同意紧急救援人员访问他/她的 PHR。此外，患者的 PHR 没有安全的记录管理，这会泄露高度机密的个人信息，例如发生的事情、时间以及谁有权访问此类信息。本文提出了一种基于许可的区块链超级账本结构和超级账本编写器的紧急访问控制管理系统（EACMS）。在所提出的系统中，我们使用智能合约定义了一些规则，用于紧急情况和紧急访问 PHR 数据项的持续时间，患者可以分配一些限制来控制 PHR 权限。我们通过超级账本编辑器根据响应时间、隐私、安全性和可访问性来实施我们提出的框架，从而分析了该框架的性能。实验证实，与传统的紧急访问系统相比，我们的框架提供了更好的效率。
Personal health records (PHRs) are private and vital assets for every patient. There have been introduced many works on various aspects of managing and organizing the PHR so far. However, there is an uncertain remaining issue for the role of PHR in emergencies. In a traditional emergency access system, the patient cannot give consent to emergency staff for accessing his/her PHR. Moreover, there is no secured record management of patient's PHR, which reveals highly confidential personal information, such as what happened, when, and who has access to such information. This paper proposes an emergency access control management system (EACMS) based on permissioned blockchain hyperledger fabric and hyperledger composer. In the proposed system, we defined some rules using the smart contracts for emergency condition and time duration for the emergency access PHR data items that patient can assign some limitations for controlling the PHR permissions. We analyzed the performance of our proposed framework by implementing it through the hyperledger composer based on the response time, privacy, security, and accessibility. The experiments con firm that our framework provides better efficiency compared with the traditional emergency access system.
