摘要
信息隐藏技术的出现和发展,为信息安全的研究扩展了一个新的领域。编程时采用最低有效位算法(LSB算法)将秘密信息嵌入作为载体的24位真彩色BMP图像中,并对算法进行了两点改进:将控制信息也当作秘密信息嵌入到BMP文件的图像数据区;嵌入信息时,与载体信息进行了一步运算。
The appearance and development of information hiding technology has opened a new field for infosec study. In the process of programming, the confidential information is embedded into the carrier of 24-place real color BMPimage by the minimum effective place algorithm (LSB algorithm). The algorithm is modified in two aspects: the control message is taken as confidential information and embedded into BMP document; while embedding information, a single-step operation is done with carrier information.
