20120281890 | BIOMETRIC AUTHENTICATION DEVICE, BIOMETRIC INFORMATION PROCESSING DEVICE, BIOMETRIC AUTHENTICATION SYSTEM, BIOMETRIC AUTHENTICATION SERVER, BIOMETRIC AUTHENTICATION CLIENT, AND BIOMETRIC AUTHENTICATION DEVICE CONTROLLING METHOD - A fingerprint image obtaining unit | 11-08-2012 |
20130038426 | AUTHENTICATION DEVICE, AUTHENTICATION SYSTEM, and AUTHENTICATION METHOD - Provided are an authentication device, an authentication system, and an authentication method, which are capable of increasing an authentication rate while suppressing an increase in a processing load. To solve this problem, the authentication device acquires a periodic temporal variation of an authentication rate, using history information stored in an authentication history storage unit storing a previous authentication result as history information, predicting whether or not a future authentication rate is lower than a previous value, based on the temporal variation of the authentication rate, and updates registration data regarding biometric information which has been registered, using input data regarding biometric information input from a user, when it is predicted that a future authentication rate will be lower than a predetermined value. | 02-14-2013 |
20130251213 | BIOMETRIC INFORMATION PROCESSING APPARATUS, BIOMETRIC INFORMATION PROCESSING METHOD - A biometric information processing apparatus includes a biometric sensor configured to acquire biometric information of a first instance, a second instance and a third instance; a processor configured to execute a procedure, the procedure comprising: extracting an authentication feature used for matching from the biometric information of each of the second instance and the third instance; normalizing the relative positions of authentication features of the second instance and the third instance by using the biometric information of the first instance; and extracting a relative feature indicating a relative positional relationship between the authentication features of the second instance and the third instance normalized in the normalizing procedure. | 09-26-2013 |
20130263282 | BIOMETRIC AUTHENTICATION DEVICE, BIOMETRIC AUTHENTICATION SYSTEM, BIOMETRIC AUTHENTICATION METHOD, AND RECORDING MEDIUM - A biometric authentication device includes a processor to execute an operation including: obtaining biometric information from a user; creating verification characteristic data from the biometric information; verifying registered characteristic data registered in a storage device with the verification characteristic data and determining whether the user is a true user; permitting execution of re-authentications up to a predetermined number of times when the user is determined to not be the true user; managing the verification characteristic data by storing the verification characteristic data in an existing group or by creating a new group and storing the verification characteristic data therein, when the user is determined to not be the true user; determining whether the user is a false user based on the number of groups; and limiting the execution of re-authentications by the user when the user is determined to be the false user. | 10-03-2013 |
20140020090 | BIOMETRIC AUTHENTICATION SYSTEM, BIOMETRIC AUTHENTICATION METHOD, AND RECORDING MEDIUM - A biometric authentication system ( | 01-16-2014 |
20140185885 | MULTI-BIOMETRIC AUTHENTICATION APPARATUS, AND MULTI-BIOMETRIC AUTHENTICATION SYSTEM - An authentication apparatus for authenticating using biometric information of a plurality of kinds including first information related to a first body part input into a first information inputting area and second information related to a second body part input into a second information inputting area includes an information existence detecting unit that detects a lack of the second information, a determination information acquiring unit that acquires information for lack determination based on third information related to the second body part input into the first information inputting area, and a pseudo lack determining unit that determines whether the lack is an actual lack or a pseudo lack based on the information for lack determination. | 07-03-2014 |
20140301615 | NARROW DOWN DATA CREATING METHOD AND NARROW DOWN DATA CREATING DEVICE - A client terminal acquires an image that includes at least a part of a fingerprint, and detects an orientation of a ridge that forms the fingerprint from the image, and detects a singular point of the fingerprint from the image, and calculates an angle formed, on a circumference of a reference circle whose center is the singular point, by the orientation of the ridge and the direction of a tangent line that comes into contact with the reference circle, and creates narrow down data that is used to narrow down matching data that is used to match the fingerprint by associating the angle with a position on the circumference of the reference circle. | 10-09-2014 |
20140363055 | BIOMETRIC AUTHENTICATION DEVICE, BIOMETRIC AUTHENTICATION METHOD, AND COMPUTER-READABLE, NON-TRANSITORY MEDIUM - A biometric authentication device includes: a biometric sensor that obtains biometric information; a memory; and a circuitry configured to: select an objective user according to density of a predetermined range including a comparison-use part data that is a part of a comparison-use feature data extracted from the biometric information in a class of a registered part data that is a part of a registered feature data; and perform comparing between a registered feature data of a selected objective user and the comparison-use feature data. | 12-11-2014 |
