摘    要:为了防止水印内容被非法窃取及篡改,本文提出了一种基于傅立叶域的安全水印算法.算法通过密钥控制水印嵌入区域和水印提取.在提取水印时,如果密钥错误,则无法得到水印信息或得到错误的水印信息.实验结果说明,所提算法操作简单实用,对几何变换、滤波、加噪等恶意攻击有较好的鲁棒性.

关 键 词:数字水印  傅立叶域  安全性

Abstract:A novel secure watermarking algorithm based on Fourier domain is presented to protect the watermark from being stolen of falsified.The embedded domain and extraction of watermarks are controlled by keys.If an attacker does not use the right keys,he/she is not able to get the correct watermark.Experiments show that the algorithm is simple and can be used in some practical applications.The algorithm is also,to some extent,robust to attacks,such as geometric transformations,filters,noises and so on.
Keywords:digital watermarking  Fourier domain  security
