摘要
针对普适家庭医疗系统(UHMS)中用户的隐私保护问题,提出UHMS中一种基于改进的角色访问控制策略、P3P技术标准和第三方可信机构的认证隐私保护模型——uPPM。模型基本实体包括用户、隐私控制中心和家庭医疗中心,其实质是将信息隐藏技术、隐私偏好策略和代理技术有机结合以适用于普适计算的特性——上下文感知。基于BAN逻辑分析论证了该模型的正确性和安全性。
In order to protect users' privacy in UHMS, this paper proposes a privacy preserving model for authentication, ubiquitous home medical system authentication privacy preserving model uPPM. The proposed model uses Platform for Privacy Preference(P3P) standard technology, improves Role-Based Access Control(RBAC) policy and credible third-party organization. There are three basic entities in model, including users, privacy control center and home medical center. The model combines with information hiding technology, privacy preferences strategies and agent technology organically to adapt to the characteristics of pervasive computing context-aware. It is analyzed and proved to be correct and safe by the model based on BAN logic.
