Abstract
An apparatus for identifying a fake fingerprint includes a housing, a prism, a first light source unit, a second light source unit, a sensor unit and a control unit. The prism is disposed in the internal space of the housing. The first light source unit irradiates light in the internal space to allow the light to pass through the prism. The second light source unit irradiates light to allow the light not to pass the prism. The sensor unit acquires a first image through the first light source unit and a second image through the second light source unit. The control unit identifies a fake fingerprint on the basis of a result acquired by comparing the first image and the second image. The housing includes a light irradiating unit that fixes and supports the second light source unit to form a predetermined angle with the fingerprint contact surface.
