Abstract
A novel blind digital image watermarking scheme is proposed in this paper. It makes full use of the multi-resolution of discrete multiple wavelet transform (DMWT) to embed a binary image watermark into the original image by changing energy difference of cross binding wavelet tree (CBWT). Experimental results indicate that the watermark embedded with the proposed algorithm is invisible, robust and secure.
