- 频域法加入数字水印的原理是首先将原始信号（语音一维信号、图像二维信号）变换到频域，常用的变换一般有DWT、DCT、DFT、WP和分形。然后，对加入了水印信息的信号进行频域反变换（IDWT、IDCT、DFT、WP），得到含有水印信息的信号。-Frequency-domain digital watermarking method by adding the principle is that first of all, the original signal (voice signal of on

- 本文提出了基于二维混沌映射的数字图像水印算法，混沌具有随机性、似噪声及对初始条件的极端敏感性等特点。将经过二维混沌映射置乱后的数字水印信号嵌入图像小波域的低频系数，实现了数字水印的隐蔽性、保密性和稳固性；利用二维混沌映射Arnold变换对水印信号进行置乱，不仅增强了水印信号保密性，同时有效提高了视觉上抵抗图像剪切攻击的能力。-In this paper, two-dimensional chaotic map based on digital image watermarking algorit
