Paper Abstract

This paper deals with some detection issues of watermark signals. We propose an easy way to implement an informed watermarking embedder whatever the detection function. This method shows that a linear detection function is not suitable for side information. This is the reason why we build a family of non-linear functions based on nth-order statistics. Used with a side-informed embedder, its performance is much better than the classical direct sequence spread spectrum method.
