The study of embedding an invisible signature watermarking in a digital image

摘要

摘要: 数字水印作为数字媒体版权保护的有效手段,近几年来在国际上引起了人们极大的兴趣,该文研究了在数字图像上实现隐形签名水印的方法,提出了一个基于小波变换和离散余弦变换(DCT)组合处理的数字图像隐形签名水印方案,它首先对原始图像作适当层次的二维小波分解,然后对低频小波逼近子图和签名水印作二维DCT,最后签名水印的DCT系数被嵌入到逼近子图的中高频段DCT系数中,实验结果表明,所提出的数字图像水印方案很好地实现了图像水印的鲁棒性和不可视性间的统一,经常规的数字图像处理操作及噪声干扰,签名水印仍能被可靠、清晰地检测出。

Abstract: As an effective method to provide copyright protection for digital media, digital watermarking has drawn extensive attention recently. By inserting the signature watermarking DCT coefficients into some middle-high frequency range DCT coefficients of the original image, the paper proposes a watermarking scheme of embedding an invisible signature in a digital image based on the combination of wavelet transform and cosine transform. The experimental results demonstrate the robustness and invisibility of digital image watermarking, and the signature watermark can be reliably and explicitly detected even though the watermarked image being degraded by commonly used image processing techniques.
