20100287369 | ID SYSTEM AND PROGRAM, AND ID METHOD - [PROBLEMS] To appropriately authenticate a user, a biometric device, and an authentication timing of a client side and prevent leak or tampering of the biometric information. | 11-11-2010 |
20100332487 | PATTERN VERIFICATION APPARATUS, PATTERN VERIFICATION METHOD, AND PROGRAM - When a false matching rate depends on data for evaluation, there is a possibility that the accuracy of pattern authentication could deteriorate in an actual operation. A pattern verification apparatus includes a correction value calculation unit that generates a plurality of unit area pairs by associating each of a plurality of unit areas generated by dividing a second pattern with each of a plurality of unit areas generated by dividing a first pattern according to a degree of similarity of a pattern, and calculates a correction value, which is suitable for matching or approximating unique feature values of the respective unit areas of the mutually associated unit areas, on the unit area pair basis; a difference value calculation unit that calculates a difference value indicating a difference between the correction values based on a comparison of the correction values between the unit area pairs that are positioned spatially adjacent to each other; and a verification evaluation value calculation unit that calculates a verification evaluation value according to a verification result between a condition indicating that patterns belong to mutually different categories and a plurality of difference values calculated by the difference value calculation unit. | 12-30-2010 |
20110019918 | PATTERN MATCHING SYSTEM, PATTERN MATCHING METHOD, AND PATTERN MATCHING PROGRAM - A problem to be solved is to provide a pattern matching system and the like which can match patterns including time change with high accuracy and safety. The problem can be solved by a pattern matching system which includes a template storage unit, a feature extraction unit, and a matching unit. The template pattern stores a template pattern. The feature extraction unit extracts features of an input pattern. The matching unit performs a first matching in which a first feature not changing with time among the features of the input pattern is matched with the template pattern and performs a second matching other than the first matching, in which a second feature changing with time among the features of the input pattern is matched with the template pattern. | 01-27-2011 |
20110115634 | BEHAVIOR MONITORING SYSTEM AND BEHAVIOR MONITORING METHOD - A storage element stores identification information identifying to-be-monitored objects (TBMO) and prohibited behavior conditions indicating behaviors respectively prohibited to the TBMO in an area. Entry monitoring elements monitor as specific TBMO, TBMO which enter the area, and judge whether or not specific identification information identifying the specific to TBMO exists in the identification information stored in the storage element. When identification information coincident with the specific identification information exists in the identification information, behavior monitoring element monitor based on the specific identification information, the specific TBMO which behave in the area, and generate behavior information indicating behaviors of the specific TBMO. Behavior judging element select specific prohibited behavior conditions corresponding to the specific identification information from the plurality of prohibited behavior conditions stored in the storage element, and produce an alarm when behaviors indicated by the specific prohibited behavior conditions coincide with behaviors indicated by the behavior information. | 05-19-2011 |
20110197113 | ABNORMALITY DETECTION SYSTEM, ABNORMALITY DETECTION METHOD, AND ABNORMALITY DETECTION PROGRAM STORAGE MEDIUM - Even if data includes a defect or an outlier in features thereof, the influence of the defect or the outlier of the features is suppressed to perform a highly precise abnormality detection, and data including high-dimensional features is processable to accomplish the highly stable detection of an abnormality. | 08-11-2011 |
20120218397 | FAKE FINGER DETERMINATION APPARATUS AND FAKE FINGER DETERMINATION METHOD - The present invention improves an accuracy to discern a fake finger created by attaching a transparent thin film to the surface of a finger.
