Abstract: A biometric authentication device includes an accommodation unit and a detection unit in which the accommodation unit accommodates a card-type recording medium providing alternative information alternative to feature information such that the card-type recording medium is faced to the detection unit, with a biologic object absent, and the detection unit detects the alternative information from the card-type recording medium, thereby collating the feature information extracted from an image of the biologic object with the feature information recorded in a memory in the case of placing the finger into the accommodation unit, and collating the alternative information from the card-type recording medium with the alternative information recorded in the memory in the case of placing the card-type recording medium into the accommodation unit.

Abstract: There is a need for providing a finger vein image inputting device that can miniaturize and thin a finger vein authentication apparatus and provide high authentication accuracy. The finger vein image inputting device according to the present invention includes a body, a band pass filter for transmitting only light of a specific wavelength, a light source for applying light to a finger placed over the band pass filter, and an imaging means for imaging transmitted light from the finger. A gradient index lens is provided between the band pass filter and the imaging means and causes refractive-index distribution around an optical axis. A polarizing filter is provided at least one of between the light source and the finger and between the finger and an imaging device.

Abstract: A personal authentication apparatus, being small/thin and also enabling to position a vital body with high accuracy, comprises: a first light source and a second light source, each of which is configured to irradiate infrared rays; and detector portion, which is configured to detect the infrared rays irradiated from the first and second light sources upon a vital body, whereby detecting a picture having characteristic information of the vital body from the infrared rays detected by the detector portion and executing a personal authentication, wherein irradiation is made from the first and second light sources upon the vital body, and position information of the vital body is detected from the infrared rays detected by the detector portion, thereby executing non-contacting positioning of the vital body.

Abstract: In a non-invasive glucose monitor is configured to, by using a heat conductive member having a body surface contacting part for contacting a surface of a human body at its one end, measures a first temperature adjacent to the body surface contacting part and a second temperature adjacent to the other end apart from the body surface. The computing device takes in data of the first and second temperature, environmental temperature, radiation heat from the body surface, reflection light caused by reflecting the light of the two different wavelength at the body surface contacting part. The computing device stores a relationship between parameters and blood glucose levels in advance, thereby converts the above-mentioned data to parameters, and calculates a blood glucose level by applying the parameters to the relationship.

Abstract: A biometric identification apparatus that can accurately and rapidly perform liveness detection with a simple structure. The apparatus includes a plurality of light sources 102, 103, 106, and 107, each having a wavelength different from one another, for emitting light to a finger 200 as an object to be identified, and receivers 104 and 105 for detecting the light passing through the finger. The ratio of the light emitted from the light sources to the light detected with the receivers is obtained as transmittance. Determination in liveness detection is made by comparing the transmittance with a previously-set threshold of transmittance.
