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 n^th-order statistics. Used with a side-informed embedder, its performance is much better than the classical direct sequence spread spectrum method.
