摘要
数字水印技术是一种在开放的网络环境中用以保护版权和认证来源及完整性的新技术。针对如何解决水印不可见性和鲁棒性矛盾这一问题提出了一种新的水印方案。实验结果表明,算法具有良好的不可见性,对常见的图像处理操作,如JPEG压缩、低通滤波、噪声攻击等具有较强的鲁棒性。
With the popularization of Internet and the development of multimedia techniques, digital multimedia has become the main means of information communication. Digital watermark is a new technology which can protect copyright and authentication source. This paper proposes a new image watermarking scheme in order to solve the contradiction between imperceptibility and robustness. Experiment results indicate that this method is very robust against the common signal processing attacks such as JPEG compression,filtering,noise contamination,cropping.
