In this paper, we propose a novel blind digital image watermarking algorithm which is resilient to many kinds of image processing attacks and geometric distortions. To embed the watermark, we first map the original watermark to another spread one aiming to fit for the image size and then embed it into the image two-level DCT coefficients we selected using a specified rule. We extract the watermark...
A RST-resilient watermarking scheme based on invariant features are proposed in this paper. The scale-invariant points of wavelet low-frequency sub-image are used to realize resynchronization after RST (Rotation Scale Translation) attacks. An improved HVS model is adopted to embed multiplicative spread spectrum watermark in DWT (Discrete Wavelet Transform) domain, and optimal water- marking detection...
