Combined with the HVS and the DWT,a double color image watermarking algorithm based on Fibonacci scrambling transform is proposed.Firstly,the color host image separation and wavelet transform to the three primary colors are carried out.Then,the color watermark image data after Fibonacci scrambling transformation are embedded into the host image wavelet coefficients corresponding to the low-frequency color,which realizes the color watermark embedding and extraction.The experimental results show that the algorithm is robust enough to fight against various conventional attacks.
