    摘要: Directional albedo of a particular article, such as an identity card, is measured and stored. When the article is later presented, it can be confirmed to be the same particular article by re-measuring the albedo function, and checking for correspondence against the earlier-stored data. The re-measuring can be performed through us of a handheld optical device, such as a camera-equipped cell phone. The albedo function can serve as random key data in a variety of cryptographic applications. The function can be changed during the life of the article through use of a variety of different card constructions (e.g., involving quantum dots, phase change materials, MEMS structures, etc.). A variety of other arrangements and features are also detailed.

    摘要: A user gestures with a wireless mobile phone device to control some aspect of its operation, or the operation of a remote system with which the device communicates. Application programs can solicit gestural information through a standardized set of interface protocols (e.g., API functions). One function, for example, solicits a running set of gesture data, and a complementary function discontinues the first function. Other functions solicit device movement data in particular directions. In some arrangements gesture data is sent by the wireless device to a remote system, which may issue a response that is dependent on the received gesture data. This response may also depend on other data obtained by the wireless device (e.g., obtained from an electronic or physical object, or sensed from the environment) and sent to the remote system. The wireless device may have different modes of interacting with users, to accommodate users with greater or lesser proficiency in gestural techniques. A variety of other features and arrangements are also detailed.

    摘要: In one arrangement, retail product packaging is digitally watermarked over most of its extent to allow machine identification by one or more inexpensive cameras at retail checkouts. Such a system also considers image fingerprints, product configuration, barcodes and other available information in identifying products. Imagery captured by conventional or plenoptic cameras is processed to derive several perspective-transformed views, which are provided to the identification system—increasing throughput by minimizing the need to manually reposition items for identification. Crinkles and other deformations in product packaging are optically sensed, allowing the surface to be virtually flattened to aid identification. A marked conveyor belt at the checkout station increases speed and accuracy, and provides other benefits to both shoppers and sellers. A great variety of other features are also detailed.

    摘要: The application discloses identification and security documents and methods and systems for authenticating such identification and security documents. In one implementation, a document includes a first surface; and a second surface. The first surface comprises a first set of print structures and a second set of print structures. The first set of print structures and the second set of print structures cooperate to obscure the location on the first surface of the second set of print structures. The second set of print structures is arranged on the first surface so as to provide a reflection pattern. In one example, the reflection pattern includes a diffraction grating. The second set of print structures is preferably provided on the first surface with metallic ink. Of course, other claims and combinations are provided too.

    摘要: The present invention relates generally to processing audio and video data. One claim recites a method of accessing content stored in a remote database. The method includes: receiving video or audio data; decoding an auxiliary machine-readable code from the video or audio data; deriving a fingerprint, which fingerprint is separate from the machine-readable code, from the video or audio data itself; providing user characteristics or an index to user characteristics; and by using the machine-readable code, fingerprint and user characteristics or information obtained with the index to user characteristics, accessing the content stored in the remote database. Of course, additional combinations and claims are provided as well.

    摘要: The invention provides methods for embedding digital watermarks for authentication of printed objects, and corresponding methods for authenticating these objects. One aspect of the invention is a method of embedding a digital watermark in a digital image to be printed on an object. The method embeds an auxiliary signal in the digital image so that the auxiliary signal is substantially imperceptible, yet machine readable. It converts the image to a halftone image using a halftoning process. If copies are made of the printed image, the image characteristics change due a change in the halftoning process used to create the copies. These changes are detected to determine whether a suspect document is authentic.
