Abstract:
1. A method for thwarting circumvention attempts on a watermarking system, the method comprising: (a) receiving a content at a content handling device that includes embedded watermarks; (b) extracting an embedded watermark from a segment of the received content, the extracted watermark being suitable for reporting to a user of the content handling device; (c) using a probability value to make a determination as to whether or not to report the extracted watermark, wherein the determination as to whether or not to report the extracted watermark includes discarding the extracted watermark according to a random value; (d) upon a determination to report the extracted watermark, reporting a value of the extracted watermark or a presence of the extracted watermark; (e) upon a determination not to report the extracted watermark, not reporting information related to the extracted watermark; and (f) repeating operations (b) through (e) for one or more additional embedded watermarks in the received content so that at least one of the extracted watermarks suitable for reporting is not reported.
