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 processor. The processor performs a process including matching 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.

A biometric authentication apparatus includes an imaging device, a display device, a memory, and a processor configured to display, on a screen of the display device, a guidance indicating a target area to be in contact with a part of a human body, detect whether the part of the human body is in contact with the target area, when the part of the human body is in contact with the target area, determine a distance between the imaging device and another part of the human body in accordance with an image captured by the imaging device, the image including the other part of the human body, and perform a change of a display position of the guidance in accordance with the determined distance.
摘要:
A processor obtains characteristics information of a biometric image captured while casting first or second illumination light onto an authentication target. The first illumination light includes light of a first wavelength, and the second illumination light includes light of the first wavelength and light of a second wavelength. The processor reads characteristics information of a biometric image captured while casting illumination light cast onto the authentication target from a memory that stores first characteristics information of a first biometric image and second characteristics information of a second biometric image. The first biometric image is captured while casting the first illumination light onto a registration target, and the second biometric image is captured while casting the second illumination light onto the registration target. The processor calculates a similarity between the obtained characteristics information and the characteristics information read from the memory, and conducts authentication.

A biometric image processing apparatus includes a touch panel, an biometric sensor configured to capture an image of a living body, and a processor. The processor performs a process including first calculating an amount of movement of the living body that moves on the touch panel while coming into contact with the touch panel, second calculating 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 detecting image noise in the captured images based on the respective amounts of movement calculated by the first calculating and the second calculating.
摘要:
A biometric authentication apparatus acquires biometric information of a user, extracts a boundary candidate where a state of the biometric information changes, to extract a region in a vicinity of the boundary candidate and having a threshold area or greater, extracts a state feature quantity having a value that changes according to a change in the state of the biometric information, from the extracted region, and judges the state of the biometric information using the state feature quantity of the extracted region.
