| 摘 要： | 在分析BMP图像文件格式的基础上，设计了基于BMP图像的多文件分散式信息隐写方案。方案采用最不重要的比特位的方法对信息进行搭载，信息文件在搭载前采用AES算法进行加密处理，然后分割成多个信息文件块，分别搭载到多个BMP图像文件，方案通过验证信息文件的Hash摘要值来保证还原出的文件的完整性。经过测试与分析表明所提方案是可行的。

| Abstract: | Base on the analysis of the BMP image file format, the dispersed steganography scheme based on multiple BMP image files is designed. It adopts the method of least significant bits to carry information. The AES algorithm is used to encrypt the information file which is split into multiple file blocks carting disparate BMP file. Information file Hash values are verified to ensure the integrity of the restored file. Test and analysis show that the proposed scheme is feasible. |
