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 The metadata is updated when it is out of date.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).

26. A desktop searching tool comprising:
executable instructions stored in computer memory for execution by electronic processing circuitry, said instructions comprising instructions to;
i. search one or more computer directories for imagery or audio files;
ii. upon discovery of an imagery or audio file, analyze the imagery or audio file for a digital watermark embedded therein, and if a digital watermark is embedded therein, recover a plural-bit identifier;
iii. obtain metadata from the imagery or audio file; and
iv. query a remote database with the plural-bit identifier to determine whether the file metadata is current. - View Dependent Claims (27, 28, 29, 30)
