抗几何攻击的盲数字水印技术耿敏，李恩平，梁华庆(中国石油大学电子信息工程系，北京102249)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。-Blind digital watermarking technology Min, Li Yun Ping, Liang Hua (China University of Petroleum Engineering Department of Electronic Information, Beijing 102249) Abstract : Digital watermarking technique is addressing the digital copyright protection an important means. Digital watermarking technology to measure the reliability standards ability to resist various watermark attack and the geometric attacks is troubled developments in the field of digital watermarking the outstanding issues, the use of digital watermarking blind watermarking algorithm. Summarizes the current attacks against the various geometric blind watermarking methods, and future research directions are discussed.
