Description: 本文通过VC技术实现了数字图像水印LSB算法 ，嵌入与提取密钥是对称密钥算法中的序列密码算法。通过设计可以方便地在宿主图像中嵌人大量数字信息 ，在嵌入水 印容量上能实现较高容量和在最低位嵌入时有较好的不可见性。LSB算法的优点是其算法简单，计算速度比较快。但是对图像的各种操作如压缩、剪切等 ，都会使算法的可靠性受到影响，也有可能通过噪声增加或有损 压缩而消除水印，即鲁棒性较差 。 -In this paper, VC technology LSB algorithm of digital image watermark embedding and extraction of key stream cipher symmetric key algorithm. Through the design can be easily embedded in the host image in a large number of digital information, higher capacity and preferably not visible in the lowest bit is embedded in the watermark embedding capacity can be realized. The LSB algorithm advantage of simple algorithm, the calculation speed is relatively fast. But a variety of operations such as image compression, shear, etc., will enable the reliability of the algorithm is affected, there may be increased by noise or lossy compression to eliminate the watermark, i.e. poor robustness.
