摘要: 针对多媒体版权信息保护的多方性和多类性,提出一种多重数字水印算法。在整数小波域,利用矩阵范数量化方法,将鲁棒水印嵌入到逼近子带,将脆弱水印嵌入到细节子带,水印提取检测可分层进行,且为盲检测。仿真表明,该算法兼具鲁棒性和敏感性,且能够较精确反映篡改区域,是一种有效的多重数字水印方案。

Abstract: A multiple digital watermarking algorithm is proposed to complete multi-sexual and multi-type of protecting multimedia information.In integer wavelet domain,robust watermarks are embedded into low frequency zone and fragile watermarks into different layers progeny details by the quantization method of matrix norm.Watermarks can be detected in different layers,which is a blind detecting algorithm.Experiments show that the algorithm not only has both robustness and fragile sensitivity,but also exactly locates distorted part.It is an effective watermarking algorithm.
