Filed:

Jun 13, 2005

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 The metadata is updated when it is out of date.

G06F 17/00
H04L 9/00

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.

Appl. No.:

11/381295

Inventors:

Sean Calhoon - Lake Oswego OR, US
Tony F. Rodriguez - Portland OR, US

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.

Watermarks can also be used to link to or facilitate so-called on-line “blogs” (or online conversations).

International Classification:

G06Q 30/00

US Classification:

382100, 235375, 23546208

Abstract:

In some arrangements, product packaging is digitally watermarked over most of its extent to facilitate high-throughput item identification at retail checkouts. Imagery captured by conventional or plenoptic cameras can be processed (e.g., by GPUs) to derive several different perspective-transformed views—further minimizing the need to manually reposition items for identification. Crinkles and other deformations in product packaging can be optically sensed, allowing such surfaces to be virtually flattened to aid identification. Piles of items can be 3D-modelled and virtually segmented into geometric primitives to aid identification, and to discover locations of obscured items. Other data (e.g., including data from sensors in aisles, shelves and carts, and gaze tracking for clues about visual saliency) can be used in assessing identification hypotheses about an item. A great variety of other features and arrangements are also detailed.
