摘　　要：提出一种将秘密信息嵌入到两幅二值图像中的信息隐藏方法。利用游程编码统计两幅二值图像的游程长度,形成两个游程序列;根据两游程序列对应的黑游程长度奇偶性是否一致嵌入秘密信息,若两游程序列大小不相等,判断较大的游程序列的剩余黑游程长度奇偶性,并嵌入秘密信息。实验结果表明,该方法与已有方法相比,失真较小,安全性较高。A data hiding algorithm is proposed that embeds secret information into two binary images. RLC length of two binary images is counted with RLC algorithm, which forms two sequences of run. According to whether parity of back run-length of two sequences is same or not, secret information is embedded. If run sizes of two sequences are different, parity of residual black run-length of larger sequence is judged, and secret information is embedded. Experimental results show that compared with existing methods, the proposed method has a little distortion and good security.
