一种新的数字水印分存算法

提出了一种小波域上把RS码与线形变换共享方案相结合的数字水印分存算法.该算法在进行秘密共享时使用了RS纠错码,降低了一定的误码率,同时,水印嵌入小波域上对JPEG和JPEG 2000压缩具有较强的抵抗能力.此外,在水印信息隐藏前,对原始水印进行了加密处理,具有很高的安全性.实验表明,该算法具有较好的隐藏效果,并能很好地抵抗剪切、擦除、压缩等攻击且健壮性强.

A New Digital Watermarking Sharing Algorithm

A digital watermarking sharing algorithm based on the Reed-Solomon code and liner transformation secret sharing scheme is presented in this paper. The algorithm uses the RS code when implementing the secret sharing and encrypts the original watermark before embedding the original watermark,so the algorithm has high robustness and security. Experimental results show that the algorithm has a good performance of hiding,anti-cutting and erasing and anti-compressing.
