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.

The present disclosure relates generally to digital watermarking including watermarking conveyed through multiple channels. One claim recites a method to detect digital watermarks carried in different channels of a physical object. The method comprising: receiving first optically captured image data, the first optically captured image data corresponding to a first channel which is detectable with visible lighting; receiving second optically captured image data, the second optically captured image data corresponding to a second channel with is detectable in a first non-visible spectrum; receiving third optically captured image data, the third optically captured image data corresponding to a third channel with is detectable in a second non-visible spectrum; and using a programmed electronic processor, analyzing the first, second and third optically captured image data to detect watermark components embedded therein. Of course, other claims and combinations are provided too.

A method for operating an electronic gaming system captures an image of a gaming object, extracts identifying information from the image of the gaming object, and uses the extracted identifying information to reference a database to determine a behavior associated with the identifying information. The method returns data to the gaming system to execute or control the behavior of the gaming system in response to the gaming object. Various system configurations for this method as well as unique applications of it are also disclosed.

The present invention relates generally to fingerprinting (e.g., deriving identifying data from audio or other media content). One claim recites a method including: obtaining identifying data derived with fingerprinting from data representing audio elements of an audio signal or derived with fingerprinting from data representing video picture elements of a video signal, the audio signal or video signal corresponding to a media signal captured by a wireless handheld device; determining a media title that corresponds to the identifying data; determining usage rights associated with at least one of the media title or a user of the wireless handheld device; identifying the user of the wireless handheld device or a library of the media titles that is associated with the user of the wireless handheld device; and adding the media title to the library of media titles that is associated with the user if so permitted by the usage rights. Of course, other claims and combinations are provided as well.
摘要:
Methods and apparatuses are provided for determining a first fingerprint of audio or video data. The first fingerprint is stored in a database or record including information pertaining to a first user or first account. The audio or video content is altered to yield a different version of the audio or video content, and a second fingerprint is determined from the different version of the audio or video content. The second fingerprint is stored in a database or recording including information pertaining to a second user or second account.

In one arrangement, information useful in understanding the content of user speech (e.g., phonemes identified by a speech recognition algorithm, data indicating the gender of the speaker, etc.) is determined at an apparatus (e.g., a cell phone), and accompanies speech data sent from that apparatus. (Steganographic encoding of the speech data can be employed to convey this information.) A receiving device can use this accompanying information to better understand the content of the speech. A great variety of other features and arrangements—some dealing with imagery rather than audio—are also detailed.

A shopper is presented with a customized online store whose inventory is defined by the shopper. In one embodiment, specification of the inventory is conducted in a bricks and mortar store—either during checkout, or by the shopper walking the aisles and scanning items with a barcode scanner pen or the like. The inventory may be defined—at least in part—by scanning items in the shopper's home. A variety of other novel features useful in on-line shopping are also disclosed.

The present disclosure relates to processing media content (e.g., video or audio signals). One claim recites a method including: receiving first content comprising a video portion or an audio portion, the first content being received over a network from a user; utilizing a multi-purpose electronic processor programmed as a content identifier module, deriving identifying data from data representing picture portions of the video portion or from data representing audible portions of the audio portion of the first content; with reference to a computerized database or computerized repository, determining a first promotional opportunity associated with the identifying data, in which the first proportional opportunity comprises an opportunity to purchase second content, the second content being related to—but different than—the first content, and determining a second, different promotional opportunity associated with the identifying data if another instance of the identifying data is thereafter received; and providing information regarding the first promotional opportunity or the second, different promotional opportunity. Of course, other claims and combinations are provided too.

A digital watermark detection method uses a matched filtering technique on a log polar re-mapping of a watermarked signal to detect peaks associated with a repetitive structure of a watermark.

Media objects are transformed into active, connected objects via identifiers embedded into them or their containers. In the context of a user's playback experience, a decoding process extracts the identifier from a media object and possibly additional context information and forwards it to a server. The server, in turn, maps the identifier to an action, such as returning metadata, re-directing the request to one or more other servers, requesting information from another server to identify the media object, etc. The linking process applies to broadcast objects as well as objects transmitted over networks in streaming and compressed file formats.
