Title: Method and arrangement for detecting a watermark

IPC: H04N5/913
Filed: 1998-05-11
Abstract: PURPOSE: A method for detection a watermark is provided to detect a watermark embedded in an information signal, and to remove a watermark from an information signal having an embedded watermark. CONSTITUTION: Recently developed methods for copy protection rely on a watermark detector to judge whether multimedia content can be copied or not. In such copy protection schemes, a watermark detector examines the multimedia content and outputs a signal(D) indicating whether a watermark is present or not. Known watermark detectors determine a decis ion variable(y) indicating to which extent the watermark is present, for example, the amount of correlation between the input signal and a reference copy of the watermark to be detected. The watermark is detected if the decis ion variable exceeds a predetermined threshold(y2). Such a detector is vulnerable to an attack which is described in this patent application. Disclosed is a watermark detector which increases the work load for an attacker by several orders of magnitude. To this end, the detector generates a random output signal for a predetermined range of decis ion values(y) between the threshold(y2) and a further threshold(y1).
