    Abstract: An original image is held in the image holder 11, and displayed on the image display 12 to be viewed by the operator. The operator inputs the angle of rotation and ratio of compression of an focal point of the original image for observing ridges more clearly. A perspective transforming unit 14 generates a result image according to corresponding perspective transformation (i.e., affine transformations), and a perspective transformed image display 15 displays the result image to the user. The operator does operations of manual plotting and manual tracing with reference to the result image. The result of the operations is inputted to and recorded in the manual input unit 16, and transformed in a feature data transforming unit 17 to feature data.

    Abstract: A user authentication apparatus is disclosed by which, even where biometrics input data of some user such as a fingerprint are low in quality and are not suitable for verification, the security of the entire system can be augmented without giving rise to increase of the cost by introduction of significant additional hardware. When a fingerprint verifying characteristic extraction section discriminates that the quality of an image of a fingerprint is insufficient or when authentication based on an inputted fingerprint by a user verification result determination section results in failure, a request to input a fingerprint is issued from a fingerprint inputting request section to the user. When necessary fingerprint inputting is performed from a fingerprint inputting section, substitute authentication by a substitute authentication section is permitted. A result of the substitute authentication by the substitute authentication section is displayed on a service permission or rejection display section. The image inputted from a fingerprint inputting section or the fingerprint inputting section is stored into a substitute authentication means user information storage section.

    Abstract: In order to extract position and direction of the first joint line of a fingerprint for stable pattern positioning in fingerprint comparison, an apparatus for extracting fingerprint features comprises a vertical strip divider (11) for dividing digitized data of a fingerprint into data of a plurality of strips with straight lines parallel to a y direction; a projection calculator (12) for obtaining histograms, each of said histograms calculated by accumulating pixel values of each of said plurality of strips in an x direction perpendicular to said y direction; a valley candidate calculator (13) for detecting candidate valleys from said histograms, one of said histograms having a locally minimum value at each of said candidate valleys; and a valley information integrator (116) for calculating a position of a joint line of said fingerprint from positional information of said candidate valleys detected by said valley candidate calculator (13).

    Abstract: A fingerprint characteristic extraction apparatus uses, in addition to characteristic amounts used in ordinary preselection processing, a novel characteristic amount obtained from a fingerprint image for the preselection processing. The fingerprint characteristic extraction apparatus includes a ridge extraction section (12) for extracting ridges from an inputted fingerprint image, a singular point detection section (13) for detecting singular points from the ridges, a main pattern discrimination section (14) for discriminating a pattern from the ridges and the singular points, and a singular point characteristic calculation section (15) for detecting characteristic amounts between the singular points from the ridges, the singular points and the pattern. The fingerprint characteristic extraction apparatus further includes a joint line extraction section (11) for extracting a joint line from the inputted fingerprint image, and a joint line characteristic calculation section (16) for calculating joint line singular point characteristic amounts from the joint lines, the ridges and the singular points.

    Abstract: A tenprint selector comprises a fingerprint pattern level feature difference calculating unit (12) which receives and compares a set of candidates for pattern level feature types of fingerprint images shown on file cards and a set of candidates for pattern level feature types of fingerprint images shown on a search card and calculates a pattern level feature difference, a card difference calculating unit (13) which calculates a card difference based on the pattern level feature difference of the fingerprint images of all fingers shown on the file cards and the search card, and a judging unit (14) which compares the card difference determined by the card difference calculating means with a predetermined card difference threshold value and judges, whether the file card shall be selected to be further checked with the search card.
