摘要
在互联网飞速发展的信息时代,网络已经成为人们生活中重要的资源库也是用于交流的重要枢纽,各种资源、信息都可以通过网络平台以压缩的形式传输。为了确保信息安全,如何在压缩文件中嵌入水印以及在传输过程中完整的保留水印的问题急需解决。为此本文利用MATLAB语言开发了基于HVS的数字水印系统,与已往的空域或变换域的水印算法不同,结合本文提出的双位嵌入法,把水印嵌入到了压缩域。通过实验仿真,结果表明这种新的水印方案与现有的水印嵌入法相比更具有抵御水印攻击力,而且更好保证了水印嵌入的鲁棒性和满足了视觉阈值效应。尤其适合用于剪切、滤波、噪声和压缩等领域的水印嵌入,从而保护这些领域的信息安全。
Along with the rapid development of computer and network technology ,the digital product transmission is more and more frequent on the network .And it mostly transfers in compressed form .So how to ensure that digital wa‐termarking is not erased in network transmission has become a pressing problem .A digital watermark system based on HVS is developed using MATLAB in this paper .It is different from the past system based on watermarking algorithm of spatial or transform domain ,the system combined with the method of double bits is proposed in this paper ,and the wa‐termark was embedded in the compressed domain .Through simulation experiments ,the results show that the water‐marking embedding scheme proposed here has good robustness for shearing ,filtering ,noise and compression .
