  • Patent number: 7706574
    Abstract: A system for authenticating messages using keystroke dynamics identifying a composer of a message using diagraphs transmitted by the use of an input device. Keystrokes are gathered by modules that determine the timing factors between each keystroke and diagraph that is created by the message composer. Once sufficient keystrokes and diagraphs are monitored that allows a generation of an identifier of a unique message composition rhythm, a unique signature of the message creator is stored within the created message. This authentication method is embedded within a message. When a user tries to access or authenticate a message, the user will be verified against the authorized signature contained within the message or authorized database of readers. If a match occurs, the user will then be allowed to access the message.

    Abstract: Processing of image data relating to moving scenarios, especially for recognizing and tracking objects located therein, requires identifying corresponding pixels or image areas in the individual successive image data sets. Likewise, processing of stereo images requires identifying the data areas which correspond to each other in two images that are recorded substantially at the same time from different angles of vision. According to the novel method of analyzing correspondences in image data sets, the image data sets that are to be compared are transformed using a signature operator such that a signature string is calculated for each pixel and is stored in a signature table allocated to the individual image data sets along with the pixel coordinates in a first step.

  • Patent number: 7620244
    Abstract: Various computer-implemented methods are provided. One method for signature recognition includes identifying a vertical element of a signature and determining a tilt angle of the vertical element. Tilt angle is defined by a line that is approximately parallel to the vertical element. In addition, the method includes determining a tilt factor. Tilt factor is defined as a horizontal offset between the tilt angle and a reference tilt as a function of distance from a signature baseline. The method further includes altering the signature using the tilt factor and comparing the altered signature to known signature(s) to determine if the altered signature matches one of the known signature(s). Another method includes altering the signature using a predetermined tilt factor and comparing the altered signature to known signature(s). If the altered signature does not match one of the known signature(s), these steps may be repeated with different predetermined tilt factors.

  • Patent number: 7529391
    Abstract: Methods and systems for training a computer to recognize and verify an individual's signature are provided. One illustrative method extracts a plurality of both global and local features from a relatively small sample of handwriting samples. In one such embodiment, only 5 samples are needed from an individual without requiring forgeries. In yet another embodiment, only three global parameters are utilized, thus reducing the complexity, and processing power, of the system. Utilizing such few global parameters also facilitates fine tuning of the systems. Further aspects of the invention relate to a multi-stage statistical system for on-line signature verification. In one embodiment, the system may comprise a simplified GMM model built on global signature properties and a left-to-right HMM model based on segmental features. In one embodiment, specific strategies are utilized to create model simplification and initialization in contrast to general GMM and HMM models.

  • Patent number: 7506153
    Abstract: A method and system for enabling registration of a user to use a computer system. The method includes providing a printed registration form containing information relating to user registration, the form including coded data indicative of an identity of the form and of at least one reference point of the form. Indicating data is received, in a processing system associated with the computer system, from a sensing device regarding the identity of the form and a position of the sensing device relative to the form. The sensing device, when placed in an operative position relative to the form, generates the indicating data using at least some of the coded data on the form. The method further includes identifying, in the processing system and from the indicating data, at least one parameter relating to user registration, and storing the at least one parameter so as to be accessible by said computer system.

  • Publication number: 20090046902
    Abstract: The present invention provides for simple and streamlined boresight correlation of FLIR-to-missile video. Boresight correlation is performed with un-NUCed missile video, which allows boresight correlation and NUC to be performed simultaneously thereby reducing the time required to acquire a target and fire the missile. The current approach uses the motion of the missile seeker for NUCing to produce spatial gradient filtering in the missile image by differencing images as the seeker moves. This compensates DC non-uniformities in the image. A FLIR image is processed with a matching displace and subtract spatial filter constructed based on the tracked scene motion. The FLIR image is resampled to match the missile image resolution, and the two images are preprocessed and correlated using conventional methods. Improved NUC is provided by cross-referencing multiple measurements of each area of the scene as viewed by different pixels in the imager.

  • Patent number: 7474770
    Abstract: The fields of biometrics and commerce can benefit from the aggressive compression techniques presented here. A novel approach to compressing the on-line handwriting signal without losing the dynamic information (i.e., velocity and order) is presented which provides the means to fit almost any signature sample within the 57-byte limit of one of the free magnetic strips on the back of conventional transaction cards such as credit or debit cards or other identity cards. The apparatus requires an on-line signature capture tablet capable of sampling the handwritten signature in a series of sampled X and Y coordinates. The compression method starts with segmenting the on-line handwriting signal into portions which may be approximated with a set of features from which the velocity and position may be reconstructed. These features are then compressed further using standard compression techniques. A Huffman coding technique is used to demonstrate this step.

  • Publication number: 20090003663
    Abstract: A method is provided whereby confidence in a validation parameter set is achieved by comparison with a known sample of a parameter in terms of the expected template comparison score as well as mean values and deviation from that score. Thus, with respect to user individual identification, biometric parameters such as fingerprint or handwriting or voice recognition can be utilised to compare the stored template for that individual with the putative biometric response in order to determine deviation from the mean. Previous systems provided a stored template and then ranging either side to simply give a pass/fail response. By adaptation of the ranging quotient for a particular individual, a percentage confidence in the pass/fail response can be achieved. For example an individual -may have a wider range of deviation than another individual and therefore close repetition of the biometric data may be indicative of a lower percentage confidence than with an individual with a narrower deviation.

  • Publication number: 20080304719
    Abstract: Various technologies and techniques are disclosed for providing bi-handwriting directional handwriting recognition and correction. A combined handwriting recognizer is provided that supports left-to-right and right-to-left language recognition by using a combined dictionary. The combined dictionary includes a dictionary from a language in a first direction, along with a backwards version of a dictionary from a language in a second direction. The combined recognizer is used with the combined dictionary to generate a most likely recognition result for mixed direction hand written input received from a user. Character by character correction is provided for mixed left-to-right and right-to-left text. The most likely recognition result is displayed in a visual order. The user can correct a particular character to a different character. When recognized text needs to be sent to a separate application, an inverse bi-directional process is performed to convert the ext from the visual order to the logical order.
