摘要: 为实现高效安全的信息存储,在分析访问权限控制与加密技术等数据保护措施及现有文件隐写系统的基础上,提出基于NTFS文件系统的最小侵入式隐写系统。该系统可作为NTFS文件系统插件,在对底层的存储结构改动很小的情况下,隐藏用户选定的文件/文件夹。与现存数据隐藏方案相比,最小侵入式系统对文件系统的修改最小,且可获得更高的效率和更少的资源消耗。

Abstract: To enhance the security and efficiency in electricity data storage, Non-intrusive Add-on Steganographic(NAS) system based on New Technology File System(NTFS) is proposed, with the analysis of the access control and encryption and some existed steganographic file system. This system can be superimposed on NTFS file systems to provide concealment of user-selected files/folders with minimal changes to the underlying storage structure. Unlike current steganographic schemes, NAS requires just bare minimum modification to the file system, and is much more efficient and cost-effective.

Key words: safe storage, steganographic file system, New Technology File System(NTFS)
