  • Patent number: 7965874
    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.

  • Patent number: 7962754
    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.

  • Patent number: 7907754
    Abstract: A further object of the present invention is to provide a biological detection device and the like capable of performing processing promptly. An input voltage with a predetermined frequency is output from an oscillating portion. By performing switching using an analog switch, the input voltage is output to an electrode via a first resistance portion. A first comparator detects an output voltage, compares the voltage with a first reference threshold stored in a storage portion, and outputs an output. Furthermore, by performing switching using the analog switch, an input voltage is output to the electrode via a second resistance portion. A second comparator detects an output voltage, compares the voltage with a second reference threshold, and outputs an output. A determination portion determines whether a test body is a living finger or a gummy finger in accordance with a combination of the values of the outputs.

  • Patent number: 7783088
    Abstract: A fingerprint sensor acquires fingerprint information of an object being in contact. A light source irradiates a light to the object from a lateral side of the fingerprint sensor. A measuring unit measures a diffusion pattern of the light passing through the object. A determining unit determines whether the object is a live finger or an artificial finger based on the diffusion pattern measured by the measuring unit.

  • Patent number: 7778449
    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.

  • Patent number: 7646893
    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.
