  Abstract

This paper presents a new watermarking scheme to reduce the detection error probability through removal of local mean values of an original signal equivalently. At first, we show that the error probability is reduced by the removal of the local mean values. In the removal process, we are in need of a method that equivalently removes the local mean valucs without modification of the origianl signal since the process changes the original signal. The method is based on the principle that as the watermark with zero local mean values is embedded, the local mean values of the original signal is equivalently removed in detection of the watermark. The principle are analytically proven, and the superiority of the proposed method is verified by experiments for variety of watermarks
