09/525865

Assignee:

Digimarc Corporation - Tualatin OR

International Classification:

H04K 100

US Classification:

382100

Abstract:

A method for decoding auxiliary data from media signals in multimedia content decodes watermarks from different media signals and uses the watermarks to control processing of the multimedia content. A copy control method decodes a watermark from one of the media signals in multimedia content, and uses the watermark to control processing of the multimedia content. Another method uses a watermark decoded from a first media signal to decode a second media signal. Yet another method uses a watermark decoded from a media signal to decode metadata associated with the media signal. Finally, another method forms a key for decoding data from at least first and second watermarks extracted from first and second media signals.

International Classification:

G06K 900

US Classification:

382100, 709217

Abstract:

A persons business card is steganographically encoded with plural-bit data. When presented to a computer system with an optical sensor, the plural-bit data is decoded and used to trigger various functionality. For example, the system can link to a remote data store containing updated contact information for the personâcontact information that is updated during the day as the persons activities make different contact information appropriate at different times. A great variety of other arrangements, some employing other steganographically encoded objects, are also detailed.

International Classification:

G06K 900

US Classification:

382100, 348460, 705 27, 710200

Abstract:

Digital data is steganographically encoded in printed materials, andâwhen sensed by an appropriately-equipped webcam or other imaging deviceâcan be used to link to associated electronic resources. Data hidden in a business card, for example, may enable linking to a persons electronic calendarâshowing the persons schedule availability. Likewise, data hidden in a corporate ID badge may serve to unlock doors at a corporate office, or to enable access to corporate computers. Many other such applications are detailed.

Abstract:

Colored images are divided into color planes and watermarks are inserted into the individual color planes. One or more watermarks can be inserted into one or more of the color planes. In order to print a color image the image is divided into color planes corresponding to the colors of ink used for printing. A separate plate is used to print each color. The different plates must be precisely aligned. Any misalignment will cause blurring in the image and may make it difficult or impossible to read a watermark in the image. Misalignment of the plates can cause the watermark data in one color plane to, in effect, cancel out the watermark data in a different color plane. With the present invention a watermark is inserted into a selected color plane only, thus there is no cancellation due to misalignment of color plates. The watermark detection and reading can be done after the image is divided into color planes.

International Classification:

H04K 1/00

US Classification:

382100, 283 72

Abstract:

Stationery, or other printable media, is encoded with a digital watermark. The watermark is not conspicuous to a human observer of the media, yet conveys plural bits of auxiliary information when optically scanned and digitally processed. The watermark can be formed by ink-jet printing, or otherwise. The encoded information can be used for various purposes, including authenticating the document as an original, linking to associated on-line resources, and distinguishing seemingly-identical versions of the same document (document serialization).

International Classification:

US Classification:

715768, 380202, 380255, 705 50

Abstract:

Methods and systems for associating watermark enabled objects with machine behaviors. Machine behaviors refer to actions by devices or systems in response to a triggering event. Examples of these behaviors include fetching a web page, opening an email client to send an email to a specific person, initiating a phone or video conference call, etc. A registration system enables users to associate machine behaviors with objects through a watermark embedded in the objects. The decoding of the watermark initiates a process for triggering the machine behaviors associated with the watermarked object. While the disclosure describes an implementation for stickers as a class of watermark enabled objects, the system and related methods apply to other forms of watermark enabled objects, including both electronic and physical objects.

International Classification:

H04K 1/00

US Classification:

382100

Abstract:

A method of performing digital asset management of media content. In this method, a watermark reader device reads a watermark embedded into media content. The watermark conveys watermark information, such as a content identifier and creator identifier. The reader forwards the watermark information to a router. The router then uses the watermark information to find a metadata database identifier. It then sends a request for metadata along with the watermark information to the metadata database identified by the metadata database identifier. The metadata database uses the watermark information to find related metadata for the media content and sends the related metadata to the reader device.
