Protecting the security of sensitive information has become a matter of great concern to everyone. Data hiding technique solves the problem to some extent, but still some shortcomings remain for researching. By analyzing the pattern of files regulation and the features of storage in FAT32 file system, a new method of data hiding was proposed, which achieves on hiding files by erasing and transferring the directory entry of destination files, and rewrites the FATs through cluster redirection technology. Theoretical analysis and experimental results show that this method has the characteristics of large capacity, good concealment, strong robustness and excellent security, but low efficiency in hiding large files.
