Abstract

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.
