Abstract :
This paper presents a multiple watermarking scheme for color images by using the concept of visual cryptography, wavelet tree, integer wavelet transform, and YCbCr color model. Experiment results show that all owners will have dual watermark authentication embedded in a protected color image, and the number of ownerships can be increased without re-computing. Applying the proposed four points distinguishing law, the owner´s dual watermarks can be extracted more imperceptibly.
