摘　　要：通过分析BMP位图文件的数据结构,提出基于BMP文件结构的信息隐藏方法.将秘密信息以文件流的操作方式嵌入到BMP文件冗余字节中,对原BMP文件的显示没任何影响.理论分析与实验结果均表明,此方法具有较好的不可见性、高效的隐藏与提取速度.With the analysis of the data structures of BMP file, information-hiding method based on the structures of BMP file is proposed in this paper. The secret information is embedded in the redundancy bytes of BMP file, which doesn＇t affect the display of former file. Theoretical analysis and experimental results show that the algorithm has high quality of hiding, detecting and security.
