ABSTRACT

Privacy protection to medical & healthcare data is one of the bottleneck problems in Internet information fusion. In order to balance data processing capability with privacy concerns, a distributed dynamic authorisation method based on blockchain is proposed to realise trustworthy data access. URLs (Universal Resource Locator) are included in the authorisation information to indicate the data access interface as well as separating patients’ privacy data from blockchain to improve data process efficiency. The contents of smart contracts are demonstrated in a case study to validate the usability of the proposed authorisation method in medical data access between different hospitals.

摘要

医疗保健数据的隐私保护是互联网信息融合的瓶颈问题之一。为了平衡数据处理能力和隐私问题，提出一种基于区块链的分布式动态授权方法，实现数据的可信访问。URL（Universal Resource Locator）包含在授权信息中，用于指示数据访问接口以及将患者的隐私数据与区块链分离，以提高数据处理效率。在案例研究中展示了智能合约的内容，以验证所提出的授权方法在不同医院之间的医疗数据访问中的可用性。
