摘要： A biometric image processing apparatus includes: a touch panel and a biometric sensor configured to capture an image of a living body. Further provided are; a first calculation unit configured to calculate an amount of movement of the living body that moves on the touch panel while coming into contact with the touch panel; a second calculation unit configured to calculate an amount of movement of each region in images captured by the biometric sensor in a period in which the living body moves on the touch panel while coming into contact with the touch panel; and a detection unit configured to detect image noise in the captured images based on the respective amounts of movement calculated by the first calculation unit and the second calculation unit.

摘要： A biometric authentication system (1) records, in a storage unit in an associating manner, position information of a feature area on an image of biometric information whose biometric authentication is successful and reference biometric information referred to in the successful biometric authentication, the feature area being specific to a living-body. The biometric authentication system (1) detects a feature area that is specific to a living-body from an image of biometric information of an input object to be authenticated. The biometric authentication system (1) narrows down the reference biometric information stored in the storage unit to reference biometric information to be compared with the biometric information of the object to be authenticated, based on the degree of similarity between the position information of the feature area obtained as a detection result and the position information of the area stored in the storage unit. The biometric authentication system (1) authenticates the biometric information of the object to be authenticated by comparing the reference biometric information obtained as a narrowing-down result and the biometric information of the object to be authenticated.

摘要： A computer detects a plurality of biometric region candidates and respective feature points of the plurality of biometric region candidates from a captured image obtained by capturing a living body. The computer selects any one of the plurality of biometric region candidates based on a position of the feature point of each of the plurality of biometric region candidates, and authenticates the living body using an image of the selected biometric region candidate.

摘要： A terminal apparatus includes an information input device that detects a coordinate value of an input operation position touched by a user, a biometric sensor that captures a capture area of a palm of the user at a time of an input operation to the information input device, to generate biometric data, and a matching unit. The matching unit matches the biometric data to a corresponding portion of registered biometric data registered in advance and read based on the coordinate value, to compute a similarity of the biometric data to the corresponding portion.

摘要： A biometric authentication device including: a biometric information acquiring unit which generates a biometric input image representing user's biometric input information; a storage unit which stores, for each of a plurality of registered users which have been preregistered, a first group feature for each of a plurality of groups set for a registered biometric image representing registered biometric information; and a processing unit. The processing unit: extracts, for each of blocks obtained by dividing the biometric input image, a local feature representing the geometric feature of the biometric input information contained in the block; classifies the plurality of blocks into a plurality of groups by blocks with a similar local feature; extracts a second group feature representing feature of biometric input information for each of the plurality of groups; calculates the degree of difference between each of the plurality of registered biometric information and the biometric input information based on the first group feature and the second group feature; selects a prescribed number of registered biometric information in ascending order of the degree of the difference; and matches the selected registered biometric information with the biometric input information.
