ABSTRACT:
Disclosed is a method for the detection of pseudo-symmetric watermarks in an information signal. The method includes receiving the information signal, wherein the watermark is embedded in respective sections of the information signal by tiling a finite number of a plurality of watermark patterns, accumulating the sections, and correlating the accumulated sections with a sum of the plurality of watermark patterns. In particular, the information signal is folded as if there was only a single basic pattern. The presence of the watermark is then detected by a cyclic sliding correlating.
