摘要: 提出一種基于矢量共享方案的數(shù)字水印算法,將矢量共享的思想用于數(shù)字水印.算法在對水印信息隱藏前,對原始水印和分塊水印都進(jìn)行擾亂處理,同時分存也具有加密作用,算法具有很高的安全性.實(shí)驗(yàn)表明,算法還具有很好的隱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. -
