H04L 9/00

US Classification:

713186, 713176, 713150

Abstract:

A variety of systems responsive to watermarked documents are detailed. In one, watermarking is employed to facilitate system access. In another, security is provided through analyzing digitally watermarked documents. In yet another, a digital watermark-based combination lock is adapted to analyze a sequence (and perhaps an orientation) of presented digitally watermarked cards.

US Classification:

705/050000, 713/185000, 380/205000, 380/054000

Abstract:

The present invention provides various methods and apparatus used in connection with steganography and digital watermarking. In one implementation, a method of obtaining information from a network of computers based at least in part on the environment associated with a first computer is provided. An object is presented within the field of view of an optical sensor device. The optical device is in communication with a first computer. The object includes plural-bit data steganographically encoded in the object. The first computer communicates with at least a second computer in the network of computers. Optical data corresponding to the object is acquired, and the plural-bit digital data is decoded from the optical data. At least some of the decoded data and environmental data is submitted to the second computer, which determines which information to send to the first computer based on the environmental data. Many other embodiments are disclosed herein.

International Classification:

H04L009/00

US Classification:

713/176000

Abstract:

The present invention provides methods and systems for authenticating identification documents. We also teach an identification document including two or more digital watermarks. The watermarks correspond with each other or with indicia carried by the identification document. The correspondence can be verified to determine authenticity. We also provide digital watermark detection methods and systems to identify the different watermarks through embedded orientation components. We then focus watermark message-decoding efforts on areas identified as likely including watermark orientation components. In one implementation we provide a watermark detection trigger to identify so-called legacy documents. The trigger may indicate the presence or expected absence of a digital watermark. In other implementations we provide a versatile document authenticator to toggle between watermarking and non-watermarking authentication processes depending on a detection trigger.

13/804314

Inventors:

Tony F. Rodriguez - Portland OR, US
Ravi K. Sharma - Portland OR, US
Matthew M. Weaver - Portland OR, US

Assignee:

Digimarc Corporation - Beaverton OR

International Classification:

G06T 1/00

US Classification:

382100

Abstract:

A content fingerprint based recognition system employs local caching of portions of a fingerprint database to manage network services for identifying which programs a user's mobile device is exposed to and the timing of events within the program. The system enables background recognition and synchronization of network services in a way that consumes less device power and bandwidth.

International Classification:

G06Q 50/00
G06Q 30/06

US Classification:

705 269

Abstract:

In one aspect, a user captures an image of a physical object (e.g., of a grocery item, using a smartphone). The depicted object is identified, such as by extracting fingerprint or watermark data from the imagery. Other imagery depicting that object—or depicting related objects—is identified on the web, and is displayed to the user on the smartphone screen. The user may select one or more of these images and direct that they be posted to a social network account (e.g., Pinterest) associated with the user. In another aspect, the user's location is sensed (e.g., an aisle of a department store), and a collection of images depicting nearby products is presented to the user for selection and posting to a social networking service. A great variety of other features and arrangements are also detailed.

International Classification:

G06T 1/00
G06F 3/12
H04N 1/32

Abstract:

Variable data printing workflows are enhanced for use with content that includes 2D code patterns, such as digital watermark data. One arrangement includes applying a filter to a content stream within a PDF document to extract both first variable pattern data for a first watermark pattern and second variable pattern data for a second watermark pattern. A first composite watermark pattern is then defined based on the extracted first variable watermark pattern data in conjunction with static watermark pattern data, and a second composite watermark pattern is defined based on the extracted second variable watermark pattern data in conjunction with the static watermark pattern data. A variety of other features and arrangements are also detailed.

Donald Haaga - Portland OR, US

International Classification:

G06T 1/00
G06F 3/12
H04N 1/32

Abstract:

Digital watermarking is adapted for the variable data printing. A reference signal serves as a proxy for optimizing the embedding a watermark in a host image to be printed. Using the reference signal, embedding parameters are generated, which are a function of constraints such as visual quality and robustness of the machine readable data. Adjustments needed to embed a unique payload in each printed piece are generated using the embedding parameters. These adjustments are stored in a manner that enables them to be efficiently obtained and applied within the RIP or press during operation of the press. Various other methods, system configurations and applications are also detailed.
