In today's world securing file data is very important. The proposed Secure File System (SFS) provides file data security using steganographic techniques in a transparent and convenient way. The proposed SFS pushes information hiding services into the Linux kernel space, mounting it between the virtual file system layers and underlying file system. After SFS is integrated with the Linux Operating System (OS), it enables OS to provide file data security as its inherent functionality. SFS requires that the user creates a directory and name it with the prefix 'Secrt' to store the encrypted file data, such as secrtdir.
