Abstract: A cryptographic method and equipment decrypting a cryptographic key by generating an auxiliary code based on a randomly determined numeric key and including a result of encryption into a cryptogram. Upon decryption, the cryptographic key is restored using the numeric key restored according to the entire cryptogram. A cryptographic method and equipment scrambles and encrypts physical characteristic information, and descrambles a result of a decryption, thereby enabling any alteration to a cryptogram to be detected because even a minor alteration thereto changes the result of the decryption. A remote identification system encrypts physical characteristic information using a password as a cryptographic key, and fluctuation of the physical characteristic information, authenticating information represented as a different bit pattern at each identifying processing is generated and sent to a transmission medium.

Abstract: When two images are matched, a partial image S is registered in advance, mutual relative position is obtained when the partial image S and an image I indicate the largest overlap. Based on the relative position, the relative position between the image T and the image I is determined. Thus, it is determined whether or not the image T and the image I match.

Abstract: 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.

Abstract: Collation information comprises anatomical information, such as finger print feature information, etc., and identification information. For the identification information, the serial number or equipment description of a device by which the anatomical information is collected, information about a route taken between a collection device and an authentication device or serial number attached to anatomical information collected by a specifying device, etc., is used instead of conventional time information. Then, the entire collation information is encrypted and is transmitted from an anatomical information collecting device to an authentication device via a network.

Abstract: 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.

Abstract: The invention provides an apparatus by which organism characteristic data included in an entire image can be acquired without producing the entire image from a plurality of partial images. The apparatus detects, every time a partial image is sampled, a relative positional relationship between the partial image and a different partial image sampled already, and extracts characteristic portion data including characteristic information unique to the organism portion from the partial image. Then, the apparatus synthesizes the extracted characteristic portion data of the partial image and characteristic portion data of the different partial image based on the detected relative positional relationship of the partial image. The apparatus can be applied, for example, to an authentication apparatus which uses a sweep type fingerprint sensor.

Abstract: 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.

Abstract: In a method for fingerprint identification, fingerprint images of parts of one finger of a person to be registered are registered as registered fingerprint images, and a relative position is calculated. A fingerprint image of a person to be identified is acquired as a read fingerprint image. Based on the relative position, a registered fingerprint image from among the registered fingerprint images is specified, and a matching degree between the registered fingerprint image specified and the read fingerprint image is calculated. The specifying and the calculating are executed until the matching degree is greater than a predetermined value.
