  • Publication number: 20180129944
    Abstract: A multi-page document is represented as a graph in which extracted page objects of the document, such as text blocks, are represented by nodes that are connected by intra-page edges and/or cross-page edges. The nodes and edges of the graph are associated with respective sets of features, the edge features distinguishing between intra-page and cross-page edges. A trained first model jointly predicts class labels for page objects, based on node and edge features. Page labels for the pages may be predicted, based on the page object predictions, optionally enforcing a constraint, such a maximum of one class label for a given class, per page. The pages can be assigned a respective category, based on the predicted classes of the page objects and respective features. Information based on the predictions is output, such as one or more of the page object class labels, the page labels, and information based thereon.

  • Patent number: 9779284
    Abstract: A system and method for preserving privacy of evidence are provided. In the method, an encrypted first image is generated by encrypting a first image acquired at a first location with a symmetric cryptographic key that is based on first information such as a license plate number extracted from the first image and first metadata associated with the first image, such as a time at which the first image was acquired. When a link is established between a second image and the first image, for example, through visual signature matching, the symmetric cryptographic key can be reconstructed, without having access to the first image, but based instead on the first metadata and information extracted from the second image. The reconstructed symmetric cryptographic key can then be used for decryption of the encrypted image to establish evidence that the license plate number was indeed extracted from the first image.

  • Patent number: 9704153
    Abstract: A method and system are disclosed for wireless payment and information collection. A central system generates a personalized application including unique application and transaction identifiers, security keys, and signatures for a user device. The user device implements the personalized application in order to access the services of the associated network. Tags, capable of short-range communication with the user devices, are deployed to service access points of the associated network. The tags and user device mutually authenticate and share identifiers. Validation of the user device results in the tag updating an irreversible counter, generating transaction certificate, and logging this transaction information. The transaction certificate and a portion of the log are communicated to the user device, and service is granted. The user device transmits the transaction information and log to the central system for billing when a network connection is available.

  • Publication number: 20160045882
    Abstract: A nanofluid includes a base fluid and multiwall carbon nanotubes (MWCNTs) dispersed in the base fluid. The MWCNTs have an outer surface provided with polar functional groups. The outer surface has decorated portions covered with nanoparticles and undecorated portions where the polar functional groups are exposed. A method prepares a nanofluid. In a first step, MWCNTs are grown on substrates by catalyst-free thermal chemical vapor deposition. In the following step, the MWCNTs' outer surface is functionalized to form polar functional groups covalently bonded thereto. Then, nanoparticles are deposited on the MWCNTs' outer surface such that the outer surface has decorated portions covered with the nanoparticles, while leaving undecorated portions where the polar functional groups are exposed. The resulting nanoparticle-decorated functionalized MWCNTs are then detached from the substrates and dispersed in a base fluid.
