The data signatures and data samples are compared respectively and processed with a processing component to determine the status of the validation process.

  • Patent number: 8031915
    Abstract: An image processing device includes a deformation processing unit that deforms at least a portion of an area on a target image, which is generated by photographing, based on a distance between a photographic device and a subject of the target image. A deformation amount adjustment unit uses a distance parameter that correlates with the distance between the photographic device and the subject of the target image when photographing to thereby adjust a degree of deformation to increase as a distance indicated by the distance parameter becomes shorter.

  • Patent number: 8019178
    Abstract: In a method for determining a resolution metric, sampled touch input data is accessed for at least one of a plurality of capacitive sensor channels in capacitive touch sensors. A resolution metric is determined based on a ratio of a required resolution and a channel resolution of at least one of the plurality of capacitive sensor channels, where for a plurality of channels the resolution metric is set to a minimum of determined individual resolution metrics for each of the plurality of channels. The resolution metric is provided as an output.

  • Patent number: 8005274
    Abstract: The invention relates to a method for determining midpoint coordinates of an image of a point-symmetrical structure stored in a volume data record, comprising: extracting a partial volume data record from the volume data record which contains the image of the point-symmetrical structure, selecting a set of points whose coordinates lie in the partial volume data record, determining a measure for each point of the set wherein the measure for each of the points of the set characterizes in each case the symmetry of the partial volume data record in relation to this point, selecting a point as a midpoint of the point-symmetrical structure that point of the set in relation to which the partial volume data record has the greatest symmetry on the basis of the previously determined measures, and storing the coordinates of the midpoint in a computer unit.

  • Patent number: 8005273
    Abstract: Methods and systems are provided for analyzing and assessing documents using a writing profile for documents, such as a payment instrument. A method may include providing a document to a computer system. In an embodiment, the method may further include comparing writing in one or more non-signature information fields of the document to at least one forger writing profile representation. In some embodiments, at least one forger writing profile representation may be obtained from at least one non-signature information field of at least one document that includes forged information. In an embodiment, the document may be identified as a document including forged information from an approximate match of at least one forger writing profile representation with writing in the document.

  • Patent number: 7983949
    Abstract: A system and method for selecting targeted information (e.g., advertisements) for serving with map views. The information is associated with target geographical areas (e.g., cities, metropolises, regions, countries) identified by the information providers. A given message or other set of information may be served with map views that significantly intersect the message's target area. A target area significantly intersects a map view if it overlaps the map view by at least a threshold percentage of the map view (e.g., 25%). Messages' target areas may first be compared with a map view to identify those that significantly intersect. Then, the messages whose target areas significantly intersect the map view may be filtered or screened based on any search terms or key words received with a request for the map view.

  • Patent number: 7925062
    Abstract: Signature data of a handwritten signature input to a signature authentication device is analyzed to determine whether to register the signature based on the characteristics of the stroke shape of the signature. If the signature registration is denied, a response message for making the signature registerable is displayed according to the way in which the signature is written. At least one of cumulative angle changes in the locus of the signature, fluctuation in the speed at which the signature was written, fluctuation in the size of the characters included in the signature, and fluctuation in the center positions of the characters included in the signature is used as the determination criterion.

  • Patent number: 7916907
    Abstract: Biometric data are obtained through a biometric input device (120) and subsequently pixelated via a pixelator (130). The pixelator (130) creates an image of the biometric data. Via a processing unit (110), a relationship between pixels of a transformed version of the image is asserted. Thus, the biometric data is rotated to a consistent inclination based on the relationship between pixels regardless of an orientation in which the biometric data were captured in the original image. Once the image has been transformed, features of the biometric data may be extracted and either stored in a data storage unit (140) or compared with previously stored feature values for validation of the biometric data.

  • Patent number: 7865018
    Abstract: Handwriting recognition techniques employing a personalized handwriting recognition engine. The recognition techniques use examples of an individual's previous writing style to help recognize new pen input from that individual. The techniques also employ a shape trainer to select samples of an individual's handwriting that accurately represent the individual's writing style, for use as prototypes to recognize subsequent handwriting from the individual. The techniques also alternately or additionally employ an intelligent combiner to combine the recognition results from the personalized recognition engine and the conventional recognition engine (or engines). The combiner may use a comparative neural network to combine the recognition results from multiple recognition engines. The combiner alternately may use a rule-based system based on prior knowledge of different recognition engines.
