【 摘 要 】

This paper introduces the basic knowledge of the digital image and information hiding technology, it is major to discuss about the embedding and abstracting process of hiding the digital file information, and the result of experiment has proved that information hiding has a better hiding effect; the examination of LSB information hiding technology, propose to compare secret information file's bits with carrier image's low bits, the success or failure of result is directly related to the effect of the hiding information. The experimental result shows that when the carrier image hide secret information, the quality of the image has a little change, and the size of the file is unchanging, and file summary is identical, moreover secret information can recover from carrier image perfectly; also shows that the LSB algorithm's hiding effect, simplicity, safety of digital image information hiding.
