摘要: 基于直方图的数字水印算法,因具有较强的抗几何攻击和图像处理攻击能力,一直是信息隐藏领域研究的热点.为了进一步扩大容量和解决比例关系相等问题,提出了多Bin多进制直方图数字水印算法概念,引入图像直方图多Bin全局调整策略,设计了一种广义的多Bin多进制图像数字水印算法.实验结果表明,设计的算法比现有算法至少提高2倍的嵌入容量;同时,在满足载体图像视觉质量的基础上,还能抵抗一定程度的几何攻击和图像处理攻击.

关键词: 直方图修改, 多Bin多进制, 全局调整

Abstract: The existing histogram-based digital watermarking algorithms,on account of its strong capability to resist geometric attack and image processing attack,have been the focus and hotspot of data hiding domain. In order to further expand capacity and resolve the relationship issue of equal proportions,the author initially proposes a concept of multi-Bin and M-ary histogram digital watermarking algorithm by introducing a new multi-Bin adjustment strategy of image histogram,and designs a generalized multi-Bin and M-ary image digital watermarking algorithm. Experiments show that the proposed algorithm achieves at least 2 times embedding capacity than the existing related works,and can resist geometric attacks and image processing attacks to some extent on the basis of satisfying the image quality.

Key words: histogram modification, multi-Bin and M-ary, multi-Bin adjustment strategy
