  • Patent number: 8398118
    Abstract: A device and method for allowing secure self-capture of multifold fingerprint impressions. The device includes a strip of fingerprint labels wrapped about a tubular ergonomic roller. A subject inserts the thumb of a first hand into the ergonomic roller and grips the roller between his thumb and forefinger. The subject then rolls the inked tip of a finger on his second hand across a label in a first rotational direction while rotating the ergonomic roller in an opposite rotational direction. To prevent fraudulent substitution of fingerprinting materials that are distributed to a subject, the materials are marked with machine readable invisible barcodes that are associated with a unique identification number. After a subject captures his fingerprints and submits his materials to a trusted observer, the barcodes on the materials are compared to the identification number to determine whether the materials submitted are in-fact those that were distributed to the subject.

  • Patent number: 6990218
    Abstract: In a fingerprint sensor that effects capacitive measurement, a sequence of fingerprint images is recorded while a finger is placed on to the sensor. By comparing the best image with previous images of the sequence, the real constituent parts of the present image are determined and the remaining constituent parts are eliminated from the best image. Thus, residual prints and disturbance components brought about by contamination of the bearing area can be eliminated from the fingerprint image.

  • Patent number: 6961449
    Abstract: A method and apparatus for computing correlating images for image recognition is provided. In particular, the method is used to compare images of a biometric object to authorize an individual or verify whether an individual is the person he claims to be. The biometric objects may include fingerprints, hand or palm prints, and retina scans. The method uses a deviation of symmetry of correlation functions to determine whether the images are of a same object.

  • Patent number: 6952489
    Abstract: A fingerprint verification method having band detection is provided. In one embodiment, the method includes capturing a fingerprint image and processing the image to determine if it includes bands attributable to changes in illumination intensity during image capture. If such bands are detected, the method preferably aborts the creation of a fingerprint template. Otherwise, if this and other security screens are passed, the method preferably includes the creation of a fingerprint template which may be compared to a stored fingerprint template to verify user identity. If such verification is established, the user is granted access privileges. One embodiment of a system implementing this method includes a fingerprint scanner for capturing fingerprint images, and an interface card having a digital signal processor (DSP) or other suitable mechanisms including software or electronics for processing the fingerprint images and generating a fingerprint template representative of the images.

  • Patent number: 6494489
    Abstract: A latent fingerprint lifting and recordation device of the type which provides a permanent and official fingerprint document. The device includes a flexible transparent latent fingerprint lifting sheet having one adhesive surface and a flat opaque somewhat thicker, less flexible sheet defining a perimeter frame and a removable central area which defines a protective cover, the perimeter frame being substantially similar in size and shape to that of, and adhered in generally coextensive fashion on one surface thereof against the adhesive side of the fingerprint lifting sheet. When the transparent fingerprint lifting sheet, with the perimeter frame adhesively attached thereto, is separated from the protective cover, an imaged latent fingerprint may be lifted and recorded on the adhesive surface. The latent fingerprint thereafter is protectively sandwiched for viewing through the transparent sheet when the protective cover is adhesively reattached to the adhesive surface to form a permanent fingerprint document.

  • Publication number: 20020050713
    Abstract: In a method of preventing false acceptance in a system for checking fingerprints, a latent fingerprint on the sensor (1) is detected by the location of a currently recorded fingerprint being compared with the location of a previously recorded fingerprint. If the location essentially corresponds, the recorded fingerprint is considered as originating from a latent fingerprint, and the fingerprint is rejected. Otherwise, the fingerprint is considered as originating from an actual finger on the sensor.
