Abstract: Methods, apparatus, and systems for signal continuity assessment using embedded watermarks are provided. The embedded watermarks are recovered from the content and one or more attributes associated with the recovered watermarks are identified. A continuity of the content can then be assessed in accordance with the one or more attributes. The continuity assessment may be based on a variety of factors, including but not limited to a determined heartbeat of the recovered watermarks, a density, separation, location, or extent, of the recovered watermarks, as well as information associated with the watermarks, such as a stego key, channel bits, packet numbers, a fingerprint, or the like.
