  • 摘要: 电子医疗病历共享能够提高医疗诊断的准确性, 促进公共医疗领域的发展. 针对目前普遍存在的不同医院之间病历共享困难、病人无法掌握其病历的使用情况等问题, 本文提出了病人可控、云链协同的病历共享模型. 各级医院组成联盟区块链, 病历数据实行链上、链下混合存储. 病历共享模型利用聚类算法, 改进实用拜占庭共识算法, 使得各节点可以更高效地达成共识. 将基于属性的加密方案与多关键词加密方案结合进行病历加密, 实现了数据可控共享, 病人可自主定义访问策略, 同时用户可以对加密病历进行安全、精确检索. 考虑到用户属性的动态更新, 本文设计了属性更新子协议. 最后评估了模型的安全性和性能, 并分析了模型的优劣势.

    类型面临问题模型应对方法
    患者参与度目前患者无法完全掌握其电子病历的使用情况 本文利用 CP-ABE 方案设计了病人可控的 EHR 分享方案, 病人可自主设置访问控制, 决定谁可以访问病历
    隐私保护EHR存储着大量隐私信息, 在数据共享时可能会遭到攻击, 以及病人和用户在分享和访问电子病历时, 其身份信息应该受到保护 本文利用加密算法将 EHR 进行加密, 确保数据的保密性; 利用签名算法及将数据 Hash 值记录在区块链网络上, 保证数据的完整性及可审计性. 同时, 通过加密及属性分配保护病人及数据用户的隐私信息
    数据互操作性目前不同医院之间数据流动性太差, 当病人就诊时, 其在另一个医院的就诊记录不能被及时分享, 同时, 数据的完整性没有办法保障本文提出了云链协同的存储方式, 利用 CP-ABE 方案进行数据加密, 病人设置访问策略, 决定谁可访问数据, 实现不同医院的病历进行共享, 用户可利用可搜索加密方案, 对密文进行搜索
    医疗纠纷当医患之间发生矛盾时, 其提供病历的真实性无法确认本文利用区块链存储病历的 Hash 值, 防止数据被篡改, 保障数据的真实性
