Abstract

We introduce the notion of weighted watermarking for proof-of-ownership watermark protection of multimedia works that are the product of more than one author and where each author is considered to be of different importance relative to the other authors. We specifically examine weighted segmented watermarking for still images and generalise previous work on performance measurement of watermark embedding patterns in the presence of cropping attacks.
