Appl. No.:

11/152684

Inventors:

Tony F. Rodriguez - Portland OR, US
Sean Calhoon - Lake Oswego OR, US
Geoffrey B. Rhoads - West Linn OR, US
J. Scott Carr - Tualatin OR, US

Assignee:

Digimarc Corporation - Beaverton OR

International Classification:

H04K 1/00

US Classification:

382100

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 The metadata is updated when it is out of date.

US Classification:

713 2, 713176, 463 29

Abstract:

Various improvements to data processing systems involve enhancements to BIOS functionality, use of identifiers associated with specific instances of hardware, and data hiding techniques—sometimes alone, sometimes in combination. Many of these improvements can be applied to increase the security of computer systems, and networks of which they form part.

G06Q 30/00
G06Q 90/00
G06K 15/00

US Classification:

235385, 235383

Abstract:

Systems and methods are provided for associating traceability codes on clamshells with unique identifiers on containers in which the empty clamshells are packed for later use. In various methods, the clamshells are marked with traceability codes and stacked together, one traceability code is read from one of the clamshells in each stack, a unique identifier is read from a container, and the stack is placed in the container. The traceability code is stored in association with the unique identifier for later retrieval. An exemplary table for making clamshell-to-container associations comprises a scanner for reading traceability codes and rails for positioning stacks of clamshells proximate to the scanner. The table can also comprise a second scanner positioned to read unique identifiers from containers placed proximate thereto. The table can further comprise a computing system to make and store the associations.

Assignee:

Digimarc Corporation - Beaverton OR

International Classification:

G06K 15/00

US Classification:

358 118, 358 328, 382100

Abstract:

The presently claimed invention relates generally to methods and apparatus employing digital watermarking. Once claim recites an apparatus including: electronic memory for storing received digital imagery or audio, in which the digital imagery or audio comprises digital watermarking including a first instruction, in which the digital watermarking is hidden in the digital imagery or audio through alterations of data representing the digital imagery or through alterations of data representing the audio; and an electronic processor programmed for: decoding the digital watermark from the digital imagery or audio to obtain a first instruction; and based at least in part on the obtained first instruction, updating said apparatus when an address associated with the digital imagery or audio changes. Of course, other claims and combinations are provided too.
