摘要
针对多水印系统中的联合问题,提出一种基于Shamir秘密共享的联合数字水印算法,把经过预处理的水印嵌入到整数小波域的中频系数上,该算法生成的水印不可见性较好,并且对单一攻击及多种复合攻击尤其对剪切攻击具有很好的鲁棒性,可验证数字作品的联合问题,并能很好地检测出作品的伪作者.
Due to the fact about joint ownership of multiple image and based on Shamir secret sharing scheme, a digital watermarking algorithm for joint ownership which embeds the pretreated watermarks in the intermediate frequency of integer wavelet transform is proposed in the article. The algorithm has a good hiding effect and is robust for single attack and even collage attacks especially for attack of cutting. This algorithm can justify joint ownership, and it could inspect the counterfeit author.
