Abstract

A vector quantisation (VQ) based watermarking scheme with shadow watermark extraction ability for multi-users is proposed. One watermark is embedded only in the host image, and only the user with the first-class key can extract the original watermark directly; other users with the second-class keys can only extract the shadow watermarks. The watermark can also be obtained by combining all the shadow watermarks.
