摘　　要：针对现有基于FAT32的文件隐藏方法存在的不足,提出了一种通过修改目录项属性和重构FAT表项序列的文件隐藏方法;分析了Linux支持FAT32的重要数据结构和函数,利用Linux中的缓冲机制,在Linux操作系统上进行了方法实现。分析表明,该方法不仅能实现不依赖于操作系统的文件隐藏,而且隐藏方法简单,运算轻量,文件隐藏强度高。In order to overcome the shortage of existing method based on FAT32 file system, an novel method using the technique of modifying directory relevant property and refactoring FAT table entry sequence was proposed. By analyzing some crucial data and functions of Linux, we realized the proposed method employing buffer mechanism in Linux operation system. The experimental result and theoretical analysis showed that this method can achieve OS independent file hidden, moreover, it can easily operate and has the advantages of lightweight computing and strong hidden effect.
