最近，世界各地医疗机构和制药公司的研究人员要求更广泛地访问医疗保健数据以进行二次使用，以提供增强和个性化的医疗服务。为此，卫生当局之间的医疗保健信息交换可以作为满足这些需求的基本概念，并能够发现新的见解和治疗方法。然而，健康数据是高度敏感和私有的信息，需要强大的身份验证和授权程序来管理对它们的访问。在这方面，云模式已被用于这些电子医疗保健解决方案中，但由于无法适应身体传感器生成的数据量的不断扩大以及它们对网络攻击的脆弱性，它们仍然效率低下。因此，由边缘计算和区块链支持的协作和分布式数据治理在提高整个系统的性能和安全性方面具有巨大的潜力。在本文中，我们提出了一个安全，高效的数据管理框架，名为“EdgeMediChain”，用于共享健康数据。拟议的架构利用边缘计算和区块链来促进和提供医疗保健生态系统在可扩展性，安全性和隐私方面的必要要求。基于以太坊的测试平台评估显示了EdgeMediChainin在执行时间方面的有效性，2000个并发交易减少了近84.75%，与传统区块链相比吞吐量更高，并且可扩展的分类账存储具有线性增长率。
Recently, researchers around the world in medical institutions and pharmaceutical companies are demanding a wider access to healthcare data for secondary use in order to provide enhanced and personalized medical services. For this purpose, healthcare information exchange between health authorities can be leveraged as a fundamental concept to meet these demands and enable the discovery of new insights and cures. However, health data are highly sensitive and private information that requires strong authentication and authorization procedures to manage the access to them. In this regard, the cloud paradigm has been used in these e-healthcare solutions, but they remain inefficient due to their inability to adapt to the expanding volume of data generated from body sensors and their vulnerability against cyberattacks. Hence, collaborative and distributed data governance supported by edge computing and blockchain promises enormous potentials in improving the performance and security of the whole system. In this paper, we present a secure and efficient data management framework, named "EdgeMediChain", for sharing health data. The proposed architecture leverages both edge computing and blockchain to facilitate and provide the necessary requirements for a healthcare ecosystem in terms of scalability, security, as well as privacy. The Ethereum-based testbed evaluations show the effectiveness of EdgeMediChainin terms of execution time with a reduction of nearly 84.75% for 2000 concurrent transactions, higher throughput compared to a traditional blockchain, and scalable ledger storage with a linear growth rate.
