基于安全目录的文件保护机制

针对现有的文件保护方法侧重于保护单个设备上文件信息的特点, 面向跨设备使用和保护文件信息的需求, 提出一种高效的基于安全目录的文件保护机制。该机制可动态地检测安全目录中的用户行为, 实时保护文件信息, 支持文件多设备安全共享。实验结果表明, 基于安全目录的文件保护机制具有良好的可用性、响应速率和存储性能。

An Efficient Safe Directory Based File Protection Mechanism

Existing file protection approaches and the applications are suitable for the users who own one single device but not the users with multiple devices. A novel mechanism is proposed that provides an efficient and fast cryptographic-based protection approach for files in an appointed directory called safe directory. The highlights are its ability to protect sensitive files automatically in a short time and the support for secure file sharing across devices. All operations in the safe directory are monitored in real time and the files in the directory are protected automatically. Experimental results show that proposed mechanism performs well in performance.
