摘要
针对云环境下电子健康记录信息安全共享的需求提出云环境下组合电子健康记录访问控制框架.在该框架中基于多个CDA文档的逻辑关系,提出并构建组合电子健康记录结构,应用基于属性的多级安全访问控制策略实现组合电子健康记录的安全管理,应用基于XLINK技术的XML Web服务实现组合电子健康记录的下载和查看.通过对比分析可说明,与已有方案相比,本方案提出的框架更加适合云环境下的电子健康信息安全共享.
To meet requirements of EHRs security sharing in the cloud computing conditions, this paper presents an access control fyamework for composite EHRs under the cloud computing environment. We propose and construct composite EHRs based on multi-CDAs＇ logical relationship. On the basis of attribute-based multilevel access control policy, we realize the security management of composite EHRs. By using the XML Web service, which based on the XML XLINK technology, we achieve the goal of downloading and checking composite EHRs. Compared with existing schemes, our project is much more suitable for EHRs security sharing in the cloud computing conditions.
