摘要： Fingerprint section images of a finger are continuously input by relative movement with respect to a fingerprint sensor, and characteristic shapes such as ridge shapes, edge lines, and portions where changes of tangent directions are large are extracted from the fingerprint section images. Common areas in which character shapes match in two fingerprint section images which are chronologically continuous are searched by correlative calculation of characteristic shapes to detect an amount of movement of images at an overlapping position. Two living body section images which are chronologically continuous are connected to each other on the basis of the amount of movement to generate an entire living body image.

摘要： ID information and organic information based on authentication demand which a service providing system received from a user terminal are inputted and stored into a use information storing unit. The ID information and organic information stored in an organic information input storing unit and an ID information input storing unit and the ID information and organic information which were inputted in the past in the use information storing unit are compared and collated by a comparing unit and a collating unit. A control unit discriminates an authentication demand by an illegal access person on the basis of results of the comparison and collation, notifies the service providing system of a discrimination result, and logs identity information of the illegal access person.

摘要： Section images of a human body part are continuously input by relative movement with respect to a read unit in an image input step, a living body section image including a character shape from an input section image group in a character area section step, and, when living body section images which include character shapes which are chronologically continuous are selected, the living body section images are connected to each other to generate a connected living body image in an image connection step. In the collation step, the connected living body image including the character shapes and living body section images which include character shapes which are not connected to each other are collated with a corresponding portion in reference information of a human body part which is registered in advance to authenticate an identical person.

An estimation unit estimates the matching precision of the extracted biometric feature information. A request unit requests an input of additional authentication information. An authentication information input unit inputs authentication information. A biometric feature information registration unit preliminarily stores registered biometric feature information. An authentication information registration unit preliminarily stores additional registered authentication information. A biometric feature information matching check unit has a matching check between the extracted biometric feature information and the registered biometric feature information. An authentication information matching check unit has a matching check between the input authentication information and the registered authentication information. A determination unit computes the matching precision by combining the matching check result about the biometric feature information with the matching check result about the additional authentication information, and determines based on the computation result whether or not the user is authenticated.

摘要： A fingerprint matching apparatus includes a fingerprint distortion detection unit for detecting whether or not a correlation object intentionally distorts the finger put on the fingerprint reading face by, for example, applying excessively large force to the finger, or dragging or rolling the finger. With this configuration, it is possible to prevent a distorted fingerprint image from flowing into the fingerprint matching apparatus and therefore the probability of accurate fingerprint correlation can be increased.
