Abstract: When an image representing biological information is input from a biological information input unit 10, such as a fingerprint sensor or the like, for obtaining an image representing biological information, such as a fingerprint or the like, statistical quantities, such as the mean value and standard deviation of the pixel values of the sampled image, are calculated. Then, using the statistical quantities, a region containing biological information is extracted, its sensitivity variations are eliminated and the effects of stains, such as a residual fingerprint is nullified, thereby generating a favorable biological image with high contrast.

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: In a system (e.g., debit card) where a PIN is entered as verification, the PIN and biometric information, which is free of being stolen or faked, are combined to realize secure user verification. The leakage and the theft of a PIN is reliably prevented, thereby realizing a high security ability. To-be-verified biometric feature data is transmitted from first transceiving interface (205) of data processing device (200) to portable electronic device (300). Biometric feature data verifying section (306) of portable electronic device (300) compares the to-be-verified biometric feature data, which has been received by second transceiving interface (301), with valid biometric feature data.

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: In order to prevent without fail the abuse of certificate information which are exchanged on a network, an orderer inputs the certificate information to a certificate terminal when placing an order for a commodity, the certificate terminal encrypts the certificate information to send it to an order receiver and holds the certificate information and a decryption key. A deliveryman, at the time of commodity delivery, inputs the encrypted certificate information to the certificate terminal, and the orderer inputs data of terminal certification to the certificate terminal.

Abstract: Every time to-be-verified biometric is input, the apparatus reflects the degree of fluctuation in the to-be-verified biometric information on narrowing down of registered feature information. After to-be-verified biometric information is input through the a biometric information input unit, the to-be-verified sub-feature information obtaining unit extracts two or more items of sub-feature information from the to-be-verified biometric information. Based on the pieces of to-be-verified sub-feature information, the to-be-verified sub-feature information assessing unit assesses an acquisition stability of each item of to-be-verified sub-feature information. According to the acquisition stability assessment, the registered feature information narrowing unit selects one or more pieces of registered feature information to be subjected to comparison/verification, thereby narrowing down the registered feature information.

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.

Abstract: The apparatus greatly reduces the registered data amount and the verification computation amount required for user verification, in comparison with the verification using image information itself, and also decreases the false verification rate. The apparatus divides a biometric information image into cells, and extracts minutia information as well as cell basic information from the individual cells. After comparison of direction information of the individual cells of the registered data with direction information of the individual cells of the to-be-verified data, thereby aligning the registered fingerprint image and the to-be-verified fingerprint image, the apparatus compares the minutia information of corresponding cells between the registered data and the to-be-verified data to make a match/non-match decision.

Abstract: In order to cause effective function when a system adopting a conventional settlement card is shifted to a system adopting a settlement card of IC card type and to enable a significant contribution to proliferation of the settlement card of IC card type, when a person who has input authentication data is authenticated as a user of a card by an authentication section, transaction data read by a magnetic stripe reader and transaction authentication data read by a memory reader are transmitted to a host server from transaction terminal equipment. The host server conducts a transaction through use of the transaction data and the transaction authentication data, both being output from the transaction terminal equipment. When the transaction is conducted, a memory writer writes data into memory of the card or rewrites data recorded in the memory.
