摘要：
This paper presents an anti-geometric attacks algorithm of color image watermarking based on scale-invariant feature transformation. Firstly, detecting SIFT feature points in the red component of true color image and filter out the feature points information; Then three level wavelet transform is performed on the blue and green component of the color image and extract the low-frequency component coefficient. Finally, binary watermark which has been scrambled is embedded in the low-frequency wavelet coefficients of blue component. The simulation results show that the algorithm is robust against signal processing and geometric attacks.
