Abstract

A discrete wavelet transform (DWT)-based image watermarking algorithm is proposed, where the original image is not required for watermark extracting, is embedded watermarks into the DC area while preserving good fidelity and is achieved by inserting the watermark in subimages obtained through subsampling. Experimental results demonstrate that the proposed watermarking is robust to various attacks.
