    Abstract: A prism member of an authentication apparatus includes a living body contact surface in contact with a visible light-radiated living body, and an imaging surface opposed to the living body contact surface and formed at a position in generally parallel therewith. The prism member includes a reflection surface in contact with the living body contact surface and the imaging surface, and to totally reflect light reflected off from the living body contact surface toward the imaging surface. The reflection surface is at an angle such that light from an inside of the prism member is totally reflected at the living body contact surface in an optical path running from the imaging surface and reaching the living body contact surface via the reflection surface. A first imaging unit captures an image including at least a part of said body contact surface and at least a part of the reflection surface.

  • Patent number: 10515266
    Abstract: Disclosed herein are system, method, and computer program product embodiments for verifying a document. An embodiment operates by receiving an initial image of a document and identifying a first imperfection on a feature of the document. Thereafter, the feature of the initial image is segmented into a first and second partially overlapping segment corresponding to a first and second portion of the feature, respectively. Subsequently, the feature's first portion is determined to be free from the first imperfection, and the first imperfection is identified in the feature's second segment. After receiving a second image of the document including the feature's second portion, the feature's second portion in the second image is determined to be free from a second imperfection. As a result, an image of the feature is created based on the first and second portions of the feature derived from the initial and second images, respectively.

  • Patent number: 10515201
    Abstract: A prism member of an authentication apparatus includes a living body contact surface configured to be in contact with the living body, and an imaging surface opposed to the living body contact surface and is formed at a position generally parallel therewith. The prism member includes a reflection surface in contact with the living body contact surface and the imaging surface, to reflect light from the former surface toward the latter surface. A visible light source below the imaging surface radiates visible light to the living body via the imaging and living body contact surfaces. The reflection surface is at an angle such that light from an inside of the prism member is totally reflected at the living body contact surface in an optical path running from the imaging surface and reaches the living body contact surface via the reflection surface. A first imaging unit captures a living-body reflected light.

  • Patent number: 10509944
    Abstract: A device for verifying a fingerprint includes: a sensing unit which captures a fingerprint image from a fingerprint of a user; a memory which stores a registered fingerprint image; and a controller which calculates a correlation coefficient between at least one region of the fingerprint image and the registered fingerprint image, and rotation-corrects the fingerprint image by a predetermined angle based on a result of comparing the correlation coefficient and a threshold value, where an area of the at least one region is within a range of about 5% to about 40% of an area of the fingerprint image.

  • Patent number: 10467841
    Abstract: Proceeds deposit machine has determination setting data containing correspondence between types of the coupons and information relating to necessity of authentication determination. A type determination unit determines the type of deposited coupon and then refers to the determination setting data. If “yes” has been set for the necessity of the authentication determination for the determined type of coupon, an authentication determination unit performs authentication determination. If the coupon is determined to be counterfeit as result of the authentication determination, the proceeds deposit machine discharges this coupon.
