    摘要: The present invention captures user's biometric data during enrollment and converts it by a given conversion parameter to create a template. It creates verification information for the conversion parameter, and enrolls it in an authentication server together with the template. The conversion parameter is stored in an IC card or the like for issuance to the user. During authentication, the authentication server verifies that the authentication terminal knows the conversion parameter, using conversion parameter verification information. Next, the authentication terminal converts user's biometric data newly captured by a conversion parameter to create matching information, and transmits it to the authentication server. The authentication server matches the matching information with the template to determine whether the user is a principal.

    摘要: In a biometrics authentication system inputting biometric information and outputting a user ID, speedup of 1:N matching on the side of server is achieved when cancelable biometrics authentication is realized in which matching is carried out. During registration, similarity of a feature to a dummy feature is searched and the feature is transformed by using a transform parameter corresponding to a nearest neighboring dummy feature. The transformed feature and a group ID are transmitted to the server and the server registers the transformed feature at the group in a DB. During authentication, like the registration process, similarity search of a feature is carried out and the feature is transformed by using transform parameter corresponding to a nearest neighboring dummy feature. The transformed feature and group ID are transmitted to the server. The server executes 1:1 matching between a template a the group in the DB and the transformed feature.

    摘要: A template sharing processing is performed between a first authentication server and a second authentication server. A client terminal generates two parameter differences, one of which is sent to the first authentication server, and the other to the second authentication server. The first authentication server transforms an already-registered template with the received parameter difference to create a temporary template and sends the temporary template to the second authentication server. The second authentication server transforms the received temporary template with the already-received parameter difference to create and register therein a further transformed template. A storage medium stores therein only a single master key for generating a parameter.

    摘要: The authentication server authenticated by a public key certificate at the time of authentication generates a difference parameter, transforms a template by the difference parameter to create a temporary registration template, and transmits the difference parameter to a tamper resistant device. The tamper resistant device generates a temporary parameter from the held transformation parameter and the difference parameter. A client terminal transforms feature using the temporary parameter, and generates temporarily-transformed feature. An authentication server receives the temporarily-transformed feature, and verifies whether the temporary registration template is in agreement with the temporarily-transformed feature.

    摘要: A strobo device in accordance with the present invention is provided with an insulated gate bipolar transistor connected to a flash discharge tube in series and a step-up capacitor to step up a voltage between the main electrodes of the flash discharge tube in the luminous operation. The step-up capacitor is connected so that a terminal on the side connected to a cathode of the flash discharge tube can have a high potential and the step-up capacitor is also connected so as to be charged by a current flowing through the flash discharge tube, which is not flashing. Thus the device realizes a rapid charging of the step-up capacitor. In this way a high voltage, at least more than twice as high as the charged voltage of the main capacitor, can be applied between the main electrodes of the flash discharge tube in the luminous operation, resulting in preventing flash failures during the repeating high-speed luminous emissions.
