Abstract: This paper proposes a kind of novel algorithm of information hiding based on classified blocks of wavelet domain and chaotic sequences encrypting hiding information. It includes the chaotic sequence making, the method of classified blocks based on texture shelter and algorithm of information embedding and extracting. Matlab is used to realize algorithm of information hiding; and the PSNR of the carrier image and the NC of extracting information are calculated. Experimental result shows that the algorithm is convenience, safeness, trustiness and plenty of information hiding. The project has better application foreground and value in Internet communication.

Key words: chaotic sequence, texture shelter, wavelet transform, information hiding

摘要： 提出一种新颖的基于混沌序列加密隐藏信息，并对载体图像进行小波域块分类的信息隐藏算法。包括混沌序列的生成、基于纹理掩蔽的块分类方法和信息嵌入与提取算法。利用Matlab实现信息隐藏的算法，计算载体图像的峰值信噪比和提取信息的相似度。实验证明，利用该算法隐藏信息更为方便、安全可靠，信息隐藏量大，在因特网通信中具有较好的应用前景和使用价值。
