Title: Applications of Blockchain in Ensuring the Security and Privacy of Electronic Health Record Systems: A Survey
Journal: Elsevier Computers & Security
Abstract: Due to the popularity of blockchain, there have been many proposed applications of blockchain in the healthcare sector, such as electronic health record (EHR) systems. Therefore, in this paper we perform a systematic literature review of blockchain approaches designed for EHR systems, focusing only on the security and privacy aspects. As part of the review, we introduce relevant background knowledge relating to both EHR systems and blockchain, prior to investigating the (potential) applications of blockchain in EHR systems. We also identify a number of research challenges and opportunities.

摘要：由于区块链的普及，目前已经提出了许多基于区块链的医疗健康应用，例如电子健康记录（EHR）系统。因此，本文将对基于区块链设计的EHR系统中的安全和隐私方面进行系统的文献综述。在调研区块链在EHR系统中（潜在）应用前，我们将介绍与EHR系统和区块链相关的背景知识作为综述的一部分。我们还提出了一些研究挑战和机遇。
