摘要:
This disclosure describes novel methods for generating unique copies of content. One method combines the functions of the master copy and unique copy watermarks. In particular, the method generates a unique copy by varying the manner in which the master copy watermark is embedded in unique copies of a content item. In one embodiment, the master copy watermark is repeated within the content item and its location is varied in a unique pattern that comprises the unique copy watermark. The unique copy is generated by producing a copy in which master copy watermarks are embedded in a unique pattern. For instance in one embodiment, the locations of the master copy watermarks in the content item are represented as a vector of delta values in which each delta value corresponds to the distance between a corresponding instance of the master copy watermark, and a neighboring instance of the master copy watermark. This vector is stored in a transaction record in association with transaction information, such as information identifying the master copy and information associated with the unique copy. Other ways of representing the unique pattern of attributes of the master copy watermark are also possible. In other embodiments, properties of the master copy watermark other than its location are varied through the content. The unique copy watermark is conveyed in the vector of deltas in these properties of the master copy watermark. Some examples of these properties of the master copy watermark signal include phase characteristics (e.g., the phase shift of a watermark carrier signal), frequency magnitude characteristics, etc. These properties are varied in a manner that does not alter the information carried in the master copy watermark. However, it does provide a variation that creates a unique copy, and the unique copy watermark is conveyed in this variation. The variation in location of the instances of the master copy watermark can be in different domains, such as a spatial domain, a time domain, a time-space domain, a transform domain (including frequency transform domains), a compressed domain, etc.

The presently claimed invention relates to audio and video processing. One claim recites a method including: obtaining streaming audio or video on a handheld wireless device, the handheld wireless device comprising: i) a programmed electronic processor, and ii) memory; using the programmed electronic processor, analyzing data representing the audio or video to extract identifying information there from; obtaining a device identifier or user identifier from the memory; communicating the identifying information and the device identifier or user identifier to a database as part of a request to add a title corresponding to the streaming audio or video to a media collection associated with the device identifier or user identifier, and in which the title is associated with the identifying information. Of course, other claims and combinations are provided too.

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.

Embedded data in gaming objects is used to authenticate the gaming object and to enhance the gaming experience in gambling venues The gaming object is authenticated automatically using information about the venue encoded in the gaming objects. The behavior of electronic gambling game systems is enhanced by extracting covert data from gaming objects and using the extracted data to control behavior of the gambling game.

The present invention relates to a variety of content identifiers (e.g., fingerprinting and watermarking) and related methods. One method recites: associating a digital rights management (DRM) identifier with content; populating a first rights registry with usage rights associated with the content, wherein the usage rights are indexed in the first rights registry according to the DRM identifier; and populating a second rights registry with at least some of the usage rights, wherein the at least some of the usage rights are indexed in the second rights registry according to a content identifier extracted or derived from the content. Other combinations are provided as well.

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.

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.
