Abstract
Watermarking typically involves adding one sequence to another to produce a new sequence containing hidden information. This method is based on modifying a distribution, obtained via segmentation, to hide information, thus allowing subsets of the distribution to still potentially reveal the watermark. We use vector quantization to segment a colour image and then shift each distribution by a random amount. The result is that we can detect a watermark without pre-processing because only comparisons between distributions are needed.
