Description: 提出了一种基于小波域的图像数字水印算法·该算法将相互正交的两种水印(鲁棒水印和参考
水印)同时添加到经过DWT后的载体图像小波系数中,然后用小波反变换得到添加了水印的图像·用提取出
的参考水印来估计图像所受到的攻击,由于提取出的鲁棒水印所受的攻击与参考水印受到的攻击一样,因此
可以估计出原始的鲁棒水印·通过对嵌入水印的图像进行加入噪声、滤波、压缩以及裁剪等大量图像处理等试
验,均能正确检测出水印,表明该算法具有很好的感知效果和鲁棒性
-A wavelet-based image digital watermarking algorithm that the algorithm will be mutually orthogonal two watermarks (watermark robust watermarking and reference) at the same time added to the carrier after image after DWT wavelet coefficients, and then using wavelet transform has been Add a watermark image to use to extract a reference to estimate the watermark image by the attacks, as a result of the robust watermark extracted suffered attacks and the reference watermark by the same attack, it can be estimated through the original Robust Watermarking of the embedded watermark image by adding noise, filtering, compression and cutting, such as a large number of image processing such as testing, can correctly detect the watermark, show that the algorithm has good performance and robustness of perception

Description: 对称密码体制的发展趋势将以分组密码为重点。分组密码算法通常由密钥扩展算法和加密（解密）算法两部分组成。密钥扩展算法将b字节用户主密钥扩展成r个子密钥。加密算法由一个密码学上的弱函数f与r个子密钥迭代r次组成。混乱和密钥扩散是分组密码算法设计的基本原则。抵御已知明文的差分和线性攻击，可变长密钥和分组是该体制的设计要点。-Symmetric cryptosystem trends will focus on block cipher. Block cipher algorithm is usually extended by the key algorithm and encryption (decryption) algorithm is composed of two parts. Key Expansion Algorithm will b-byte master key customers to expand into r sub-key. Encryption algorithm from a weak cryptography on the function f and r sub r th iteration key component. The spread of chaos and key block cipher algorithm is the basic principle of design. Explicitly known to resist differential and linear attacks, variable length keys and grouping of the system design features.

Description: research on against geometry attacks watermarking technology. A digital Watermarking scheme, which is based on combination of simple and reliable harries detector and image normalization, is proposed. The feather points remain holding after geometry attack. Applying image normalization to these non-overlapped circles which centered at the feature points, after that, we can determine area for watermark embedding. -research on against geometry attacks watermarking technology.
