摘要

To provide an authentication device and method for a security medium including a reflective volume hologram, capable of easily performing authentication determination and a security medium including the reflective volume hologram.;An authenticity determination device 1 for a security medium 10 including a reflective volume hologram 2 includes a light source L disposed on the front surface side of the reflective volume hologram 2 so that light emitted therefrom is incident on the reflective volume hologram 2, a first observation device 11 disposed in a pre-designed diffraction direction of the reflective volume hologram 2, and a second observation device 12 disposed in a direction other than the pre-designed diffraction direction of the reflective volume hologram 2. Light including a pre-designed diffraction wavelength is emitted from the light source L to be incident on the reflective volume hologram 2, and at this time, when the light amount observed in the first observation device 11 is larger in the diffraction wavelength than in other wavelengths, and the light amount observed in the second observation device 12 is smaller in the diffraction wavelength than in other wavelengths, it is determined that the reflective volume hologram 2 is genuine.
