摘要
数字水印技术是解决数字作品版权保护的一个重要手段。衡量数字水印技术可靠性的标准是能否抵抗各种水印攻击,而几何攻击是目前困扰数字水印领域发展的突出问题,数字水印多采用盲水印算法。总结了当前抗几何攻击的各种盲水印方法,并对今后的研究方向进行了探讨。
Digital watermarking technology is an important method to protect the copyright of digital works. Its reliability mainly depends on whether it can resist kinds of watermarking attacks. Geometric attack is a crucial problem to the development of digital watermarking. Blind watermarking is used widely. In this paper, current methods against geometric attacks for blind watermarking are summarized and the research directions are discussed.
