Publication number: 20100208975Abstract: The present disclosure provides digital watermarks through multiple channels. The channels may include, e.g., visible, ultraviolet and infrared channels, or be based on predetermined materials. The non-visible channels can be selected to fluoresce either in the visible or IR/UV spectrums upon the appropriate illumination in the infrared or ultraviolet spectrums. The watermarks in the various multiple channels can cooperate to facilitate watermark detection or to authenticate an object in which the watermarks are embedded. In other implementations the multiple watermarks include so-called orientation components. A relative relationship between the orientation components is used to convey data. Of course, other combinations are provided too.Type: ApplicationFiled: April 27, 2010Publication date: August 19, 2010Inventors: Robert L. Jones, Joel R. Meyer, Kenneth L. Levy, Steven W. Stewart

Publication number: 20090187435Abstract: Driver's licenses and other security documents include one or more machine-readable features, each conveying plural bits of information. These features are used in a variety of ways to increase security, and/or to enhance functionality. In one embodiment, data encoded on a driver's license is used at airport check-in, to link to a state DMV database and obtain information by which the document, and its custodian, can be authenticated. In like fashion, a license can be used to authenticate a bearer and/or his/her age prior to the sale of alcohol or tobacco products. In other embodiments, different elements of a driver's license (e.g., the substrate, photo, text data, and machine-readable data) are logically bound together (e.g., interlinked through payloads conveyed by different machine-readable features) as a deterrent against counterfeiting. Driver's licenses can be similarly logically bound to personal checks and other documents. Many other arrangements are also disclosed.Type: ApplicationFiled: January 13, 2009Publication date: July 23, 2009Inventors: J. Scott Carr, Bruce L. Davis, Stephen K. Decker, Jonathan L. Hawes, William C. Hein, III, Kenneth L. Levy, John Munday, Burt W. Perry, Philip Andrew Seder, Joel R. Meyer, Tyler J. McKinley, Hugh L. Brunk, Steven W. Stewart

Patent number: 7254249Abstract: Digital watermarking technology is used to convey location data for images or objects depicted in video. A digital watermark may associate geovector information with the video or object and areas depicted in the video. A geovector may include location coordinates such as longitude, latitude, altitude, etc. In one implementation, geovector information is embedded within a video frame so as to correspond with an area depicted in the video frame's center or off-center location. In a second implementation, a geovector includes an identifier or indexing protocol for use in a video management system.Type: GrantFiled: February 20, 2003Date of Patent: August 7, 2007Assignee: Digimarc CorporationInventors: Geoffrey B.

Publication number: 20030056104Abstract: The present invention provides various techniques for encoding hidden information in checks and other security documents. The hidden information provides an authentication tool. In one implementation, we provide a method for encoding a security document with information. The security document includes a substrate having printing thereon. The information is hidden in the printing and corresponds to text or numbers conveyed by at least a portion of the printing. The method includes dividing the information into a plurality of payload sets, wherein each payload set includes a sub-set of the information, and encoding the payload sets across the substrate. The plurality of payload sets is concatenated in order to retrieve the information.Type: ApplicationFiled: August 30, 2002Publication date: March 20, 2003Inventors: J. Scott Carr, Geoffrey B.
