摘要: 提出一种基于矢量共享方案的数字水印算法,将矢量共享的思想用于数字水印.算法在对水印信息隐藏前,对原始水印和分块水印都进行扰乱处理,同时分存也具有加密作用,算法具有很高的安全性.实验表明,算法还具有很好的隐藏效果和抗剪切功能.

Abstract: A digital watermarking sharing algorithm based on vector secret sharing scheme is presented, which applies the thought of vector sharing to digital watermarking. The algorithm disturbs both the original watermark and the sharing block watermark before hiding the original watermark. The sharing processing has the effect of disturbing too. So the algorithm has highly security. Experimental results show the algorithm has a good effect of hiding and anti-cutting. -
