摘要： 为提高抗压缩和抗噪声攻击能力，提出一种基于条带波变换的图像水印加密算法.对水印图像进行Arnold置乱、混沌调制及BCH纠错编码，提高了数字水印的安全性；在载体图像条带波系数的低频最佳几何流为对角的位置嵌入水印信息的BCH码.实验结果表明，条带波域嵌入方法克服了DCT域的块效应，继承了小波域的优点，具有较强的数据信息隐藏能力和较好的抗攻击性能，弥补了小波域的不足，具备了更强的抗噪声能力和抗压缩能力.

Abstract: To improve the resistance to compression and noise attack， a kind of image watermark encryption algorithm based on bandelet transform was put forward. Arnold scrambling， chaotic modulation and BoseChaudhuriHocquenghem(BCH)error correction coding were used in the watermark processing of images， which improved the security of the digital watermarking. The BCH codes were embedded at the location where the low frequency optimal geometric flow of the coefficient for the carrier image bandelet was diagonal. The results showed that the bandelet domain embedding method overcame the block effect in the Discrete Cosine Transform(DCT) domain and inherited the advantages of the wavelet domain， which had relatively strong data hiding capacity and better attack resistance. The bandelet domain embedding method made up the shortages of the wavelet domain and had much stronger resistance to compression and noise attack.

Key words: digital watermark, bandelet transform, Arnold scrambling, chaotic modulation, BoseChaudhuriHocquenghem code
