摘　　要：信息安全乃至个人信息的安全随着信息化的普及逐渐成为社会关注的焦点。借鉴物理隔离的思想,提出一种基于隔离技术的、可个性化配置的桌面保护系统,克服用户在上网过程中的权限透明问题,有效保证个人信息安全。在分析上述个性化桌面保护系统相关技术的基础上,给出其控制模型并对该模型进行了描述。最后,对个性化桌面保护系统所涉及的类物理隔离技术、基于角色的访问控制、信息强审计、信息流向控制、用户访问日志等关键技术进行了详细阐述。As the informatization is popularized, information security as well as individual information security, has come to be the focus of the society. Using the ideology of physical isolation, a desktop protector advanced, which could be individual configured and efficiently guaranteed the individual information. With this desktop protector, the user can use the network in his transparence privilege and protect his information in security. Based on analyzing the corresponding technology of such individual deslaop protector system, the control model of the system is presented. After describing the model, some key techniques are particularly discussed, such as quasiphysical isolated technology, role based access control, information strong audit, information flow-direction control and users visiting log,
