  • Publication number: 20230359717
    Abstract: Authentication is performed by confirming that the true operator presents his/her own biometric authentication information at a common portable information terminal. The biometric authentication system has an image capture unit that acquires first and second image data of different biometric areas of an operator during a predetermined period, a display that displays a guide to guide the operator to the location of the biometric area in order to capture different biometric areas of the operator, and a memory that stores biometric authentication information of the operator in advance. Furthermore, the first vital information and the second vital information are extracted from the image data of the different biometric areas, respectively, the identity of the operator is determined based on the first vital information and the second vital information, and if the identity of the operator is confirmed, the biometric authentication is performed.

  • Patent number: 11645864
    Abstract: To provide an imaging device capable of reducing discomfort caused by visible light. A light source can emit the visible light and invisible light as irradiation light. An imaging unit captures an image of an irradiation region irradiated with the irradiation light to acquire an image. A processor causes the imaging unit to acquire a detection image in a first irradiation mode in which the invisible light is emitted from the light source, and determines whether a biometric object is presented in the irradiation region based on the detection image. When the biometric object is presented, the processor causes the imaging unit to acquire the biometric image obtained by copying the biometric object as the image in a second irradiation mode in which the visible light and the invisible light are emitted from the light source.

  • Patent number: 9342730
    Abstract: An identification apparatus keeps the conditions for imaging uniform among successive identifications, and requires a user to perform only a series of simple maneuvers. The apparatus comprises a guide member, a light source, and an imaging unit. The guide member includes a pattern or structure for a user to position his/her finger thereon or to approach his/her specific finger region thereto. A contact member is located in the guide member where a fingertip is positioned. An optical opening is formed at a position coincident with where a finger to be imaged should be placed. The light source radiates near-infrared light through the portion of the finger to be imaged. The imaging means acquires an image of the finger, and the apparatus compares the image to previously registered images. The apparatus may also include dual light sources power saving functionality, and means for limiting the interference of external light sources.
