摘要
为了改善数字水印算法性安全,增强水印算法的抗干扰性,设计了一种基于小波域的水印算法,算法结合了Arnold置乱方法和DWT变换多分辨率特性,采用线性的、不同的嵌入强度的方法,有效地提高了水印的安全性。实验结果表明,该算法具有较好的抗压缩、抗剪切性和抗噪性。
Based on Arnold scrambling technology, making use of characteristics of DWT, the present study has designed a digital watermarking algorithm. It increases effectively safety for digital watermarking by making use of the linear and two different embedding operator. The findings of the experiment suggest that it has the fairly good resistant ability of compression, cutting and noise.
