随着医疗保健系统的持续数字化转型以及患者数据共享成为了解患者健康史的重要步骤的需求，网络安全必须处于最前沿并成为重中之重。因此，大多数现有的数据共享系统依赖于可信的第三方。因此，这些系统缺乏互操作性、数据碎片化、完整性、安全性和隐私性。在我们之前的工作中，我们设计了一个基于区块链的框架来保护患者健康记录交换（SPHRS），该框架在撤销或授予访问权限以及为护理提供者创建访问策略方面完全由患者控制。该框架通过使用智能合约进行用户身份认证和验证来实现安全性。采用分布式IPFS存储方式存储加密后的患者健康记录，并保证不变性。此外，NuCypher软件利用代理重新加密协议来安全地存储加密和解密密钥。在这项研究中，我们通过测试区块链交易的气体消耗，吞吐量，平均响应时间和平均值等指标来评估框架的性能。字节此外，该框架的安全性进行了讨论。SPHRS展示了我们如何建立一种新的方法来有效地保护患者健康记录共享。然而，它显示了一个有希望的结果，可以潜在地改变数字患者医疗保健系统。
With the healthcare system’s ongoing digital transformation and the need for patient data sharing to become an essential step to understanding the patient’s health history, cyber security must stay at the forefront and be made a top priority. As a result, most existing data-sharing systems depend on trusted third parties. As a result, these systems lack interoperability, data fragmentation, integrity, security, and privacy. In our previous work, we designed a framework based on Blockchain to secure patient health records exchange(SPHRS) that is fully controlled by the patient in terms of revoking or granting access and creating access policies for care providers. The framework achieves security by using smart contracts for user identity authentication and verification. The distributed IPFS storage is applied to store the encrypted patient health records and ensure immutability. In addition, NuCypher software takes advantage of a proxy re-encryption protocol to store the encryption and decryption keys securely. In this study, we assess the framework’s performance by testing metrics such as blockchain transactions’ gas consumption, throughput, Average response time, and average. Bytes. Furthermore, the security of the framework is discussed. SPHRS demonstrates how we can establish a novel approach to efficiently secure patient health record sharing. However, it shows a promising result that can potentially transform the digital patient healthcare system.
