Thursdays the PTO publishes new pending patent applications. Both of this week's Spotlight Applications concern aspects of digital watermarking. Assigned to Opera Solutions, the first application discloses techniques for secure document distribution. Assigned to Digimarc, the second application discloses techniques for identifying objects.
20140053252, "System and Method for Secure Document Distribution," assigned to Opera Solutions, LLC.
A system and method for secure document distribution is provided. The system includes a computer system and a secure document distribution engine. The system includes a two-factor authentication system that includes a password and a hardware component. Documents can be accessed from a network (e.g., the Internet, a cloud computing resource, etc.), via a link as an e-mail attachment, or as a stored file. Redistribution of documents by malicious authorized users is not possible without attribution due to the view-only nature of the system in combination with other measures that include event logging and document watermarking. Access can be revoked or blocked in real time, regardless of how the files were distributed or where they reside.
20140052555, "Methods and arrangements for identifying objects," assigned to Digimarc.
In some arrangements, product packaging is digitally watermarked over most of its extent to facilitate high-throughput item identification at retail checkouts. Imagery captured by conventional or plenoptic cameras can be processed (e.g., by GPUs) to derive several different perspective-transformed views--further minimizing the need to manually reposition items for identification. Crinkles and other deformations in product packaging can be optically sensed, allowing such surfaces to be virtually flattened to aid identification. Piles of items can be 3D-modelled and virtually segmented into geometric primitives to aid identification, and to discover locations of obscured items. Other data (e.g., including data from sensors in aisles, shelves and carts, and gaze tracking for clues about visual saliency) can be used in assessing identification hypotheses about an item. Logos may be identified and used--or ignored--in product identification. A great variety of other features and arrangements are also detailed.
