Forgery prevention medium |
| abstract |
A forgery prevention medium includes a volume hologram layer on which an interference pattern is recorded after being exposed to at least an emitted laser beam; a digital watermarking information layer on which digital watermarking information is recorded; and a substrate film, and the information recorded on the digital watermarking information layer is interpreted by emitting a light beam that is different in one or more of the characteristics, incidence direction, incidence angle and incidence wavelength, from a hologram reproduction illumination beam used to reproduce an image recorded on the volume hologram layer. |
