WIPO Patent Application WO/2021/038615
Kind Code:
A1
Abstract:
Provided is a bloodstream authentication device in which scattering of light inside a finger is mitigated, there is no effect of the reflection of the finger side surface, the effect of light from outside is reduced, and the precision of authentication can be improved. A bloodstream authentication device disclosed in the present application comprises movable parts 1, support parts 2, light sources 3, pressure sensors 4, an imaging unit 6, etc. Each movable part 1 is brought into contact with an inserted finger F of a person being authenticated, and is turned by the finger F. Each movable part 1 is pivotably supported by the support part 2 with a rotation shaft 13. Each support part 2 can move due to a biasing force of a biasing means S fixed on another surface on the opposite side of the surface that contacts the finger F. Each light source 3 is contained inside the movable part 1, and irradiates light onto the back of the finger F. Each pressure sensor 4 is fixed to the biasing means S on the opposite side from the support part 2.
