摘要
随着计算机、网络和通信技术的飞速发展,特别是Internet的普及,信息的安全保护问题日益突出。数字水印技术作为知识产权保护的有效手段,易受到各种恶意攻击而导致水印无法提取。本文研究了数字水印在各种常见攻击下的鲁棒性度量问题,以标准测试工具Stirmark软件为平台,定量分析了Digimarc水印对信号处理变换和几何变换攻击的鲁棒性,所得结果有助于数字水印算法的设计和改进,使其具有更好的安全性和稳健型。
With the rapid development of computer,network and communication,espically the popularization of the Internet, information security and protection have become a key and attractive problem.Digital watermarking is an effective method for copyright protection,but it may easily be attacked and destroyed,so that the watermark is undetectable.The robustness measuring of digital watermarking under different attacks is studied, and regarding the Stirmark software as standard measuring tool, quantitative analysis of the robustness of Digamarc watermark on the signal process Transformation and geometric transformation attacks is made.The results can help design and improve watermarking algorithms holding better security and robustness.
