通常，病历（MR）包含患者的疾病导向的敏感信息。此外，MR需要在不同机构之间共享，例如，因此，保留MR的隐私和完整性至关重要。基于区块链的安全MR共享系统可以适当地管理这些方面。本文提出了一种基于区块链的电子（e-）MR共享方案，该方案（i）将医学图像和文本视为输入，（ii）通过由非对称密码系统和动态DNA编码组成的双重加密机制来丰富数据隐私，（iii）通过将加密的e-MR存储在为区块链中的每个用户指定的不同块中来确保数据完整性，以及（iv）最终，使授权实体能够通过解密重新获得e-MR。初步评估、分析、与最先进的作品进行比较等，这意味着拟议计划的有效性。
Usually, a medical record (MR) contains the patients’ disease-oriented sensitive information. In addition, the MR needs to be shared among different bodies, e.g., diagnostic centres, hospitals, physicians, etc. Hence, retaining the privacy and integrity of MR is crucial. A blockchain based secure MR sharing system can manage these aspects properly. This paper proposes a blockchain based electronic (e-) MR sharing scheme that (i) considers the medical image and the text as the input, (ii) enriches the data privacy through a two-fold encryption mechanism consisting of an asymmetric cryptosystem and the dynamic DNA encoding, (iii) assures data integrity by storing the encrypted e-MR in the distinct block designated for each user in the blockchain, and (iv) eventually, enables authorized entities to regain the e-MR through decryption. Preliminary evaluations, analyses, comparisons with state-of-the-art works, etc., imply the efficacy of the proposed scheme.
