    Abstract: This patent document relates generally to steganography and digital watermarking. One claim recites, a method of encoding auxiliary information in an image or video. The method includes: determining a watermark tweak for an attribute of an image or video sample to encode auxiliary information in the image or video; and altering color values of the image or video sample to effect the watermark tweak, said altering alters color values based at least in part on both: i) visibility of color value alterations, and ii) anticipated watermark detection. Of course, other claims are provided too.

    Abstract: The present invention provides methods and systems to improve network searching for watermarked content. In some implementations we employ keyword searching to narrow the universe of possible URL candidates. A resulting URL list is searched for digital watermarking A system is provided to allow customer input. For example, a customer enters keywords or network locations. The keywords or network locations are provided to a watermark-enabled web browser which accesses locations associated with the keywords or network locations. Some implementations of the present invention employ a plurality of distributed watermark-enabled web browsers. Other aspects of the invention provide methods and system to facilitate desktop searching and automated metadata gathering and generating. In one implementation a digital watermark is used to determine whether metadata associated with an image or audio file is current or fresh. The metadata is updated when it is out of date. Watermarks can also be used to link to or facilitate so-called on-line “blogs” (or online conversations).
