%X A digital watermarking algorithm on color image based on human visual system and wavelet transform was proposed.This algorithm adopts YIQ color space to watermark embedding.The three-time random scrambling processing operations were made for the watermark before embedding.Then the wavelet coefficients of Y component were classified making use of the masking peculiarity of visual system.The calculation of JND values and the quantization of wavelet coefficients were made.Finally,the three scrambled watermarki...
