摘要
作为信息隐藏技术的一个具体表现形式,数字水印是一种有效的数字产品版权保护和数据安全维护技术,在版权保护、"指纹"识别、拷贝保护、广播监视等方面有重要的应用[1]。用LSB算法对水印进行了嵌入和提取,并用Matlab实现了水印算法的仿真。通过仿真结果可以看出,LSB算法不影响原始图像的视觉效果,而且水印提取效果也较好,说明LSB算法具有较好的稳健性和良好的水印不可见性。
As a specific form of the ilfformation hiding technology, the digital watermarking is the effective technology of digital copyright protection and data security maintenance which is importantly applied in the aspect of copyright protection, ＂fingerprint＂ i- dentification, copy protection and broadcast monitoring. The LSB algorithm is used to make imbedding and extraction to the watermark and the simulation of watermarking algorithm is made with Matlab. The simulation results show that the LSB algorithm does not affect the visual effects of the original image and watermark extraction results are better, it indicates that the LSB algorithm has better robust- ness and good watermark invisibility.
