watermark(matlab)
- 数字水印的程序，用matlab编的,包含数字水印你的嵌入、提取及鲁棒性分析-digital watermarking process, using Matlab series, including your digital watermark embedding, robust extraction and analysis
logistic_dwt
- 】利用混沌动力学系统中logistic 映射先对水印图像进行置乱预处理以增强其鲁棒性, 在小波域中将原始音频信号按比例分段, 此比例为原始音频信号低频部分与水印信号个数之比, 然后将水印信号加入到音频信号的 低频部分。用StirMark 攻击后的实验结果表明, 该算法对StirMark 的部分攻击具有一定的鲁棒性。-The logistic- map sequences to encrypt the watermark are used. The original audio signal
Many-watermarking-embedding
- 提出了一种鲁棒的多水印嵌入与检测算法,该算法基于小波域,且提取水印时不需要原始图像,保护了原始图像的安 全。在该多水印算法中,提出并使用了一种将密码学和常规的数字水印制作方法- - - 叠加法和量化调制法,有机结合起 来的新的方法,在水印嵌入时,不同的水印,生成与该水印相关的不同的密钥,在进行水印的提取时,用不同的密钥和待测的 图像提取出相应的水印。通过将密钥向第三方注册,可以获得对原始图像的所有权。-A robust multi-watermark embedding and de

- 文件夹LSB中是空域LSB算法程序，文件夹COX中是Cox算法主要程序，文件夹DCT中是频域加在中频的算法的程序。 步骤：把LSB，COX，DCT三个文件夹考在MATLAB目录下； 运行lsb_embed,programme,dct2_embed_mod即可。其中PSNR.m是计算峰值信噪比程序；attact.m & robust.m是攻击程序。-Content: folder LSB of spatial LSB algorithm program, folder COX Cox a
code-for-robust-feature-based-image-water-marking
- A digital image watermarking scheme must be robust against a variety of possible attacks. In the proposed approach, a new rotation and scaling invariant image watermarking scheme is proposed based on rotation invariant feature and image norma
Image-Watermarking-using-Tetrolet-Transform
- This paper proposes new watermarking technique based on Tetrolet domain. The Tetrolet transform is a new adaptive Haar-type wavelet transform based on tetrominoes. It avoids Gibbs oscillation because it applies the Haar function at the edge of the im

- In this paper we proposed a method of embedding owner’s speech signal. Speech being a biometric data, the watermark signal in this method is expected to be more meaningful and has closer correlation with copyright holder. The main issue of co
