论文摘要
电子健康记录（EHR）在世界范围内广受欢迎。然而，当前的EHR系统与隐私和安全有关。我们提出了一种机制，该机制为大多数这些问题提供了解决方案。使用许可的以太坊区块链使世界各地的医院和患者可以相互联系。我们的机制结合了对称和非对称密钥密码学，以确保记录的安全存储和选择性访问。它使患者完全控制了他们的健康记录，还允许他们授予或撤销医院访问其记录的机会。我们已经使用IPF（行星间文件系统）来存储具有分发并确保记录不变性的优势的记录。提出的模型还维护了疾病的统计数据，而不会违反任何患者的隐私。
Electronic Health Records(EHR) are gaining a lot of popularity all over the world. The current EHR systems however have their fair share of problems related to privacy and security. We have proposed a mechanism which provides a solution to most of these problems. Using a permissioned Ethereum blockchain allows the hospitals and patients across the world to be connected to each other. Our mechanism uses a combination of symmetric and asymmetric key cryptography to ensure the secure storage and selective access of records. It gives patients full control over their health records and also allows them to grant or revoke a hospital's access to his/her records. We have used IPFS(inter planetary file system) to store records which has the advantage of being distributed and ensures immutability of records. The proposed model also maintains the statistics of diseases without violating the privacy of any patient.
