<p><P>PROBLEM TO BE SOLVED: To provide an antifalsifying medium with high reliability in security. <P>SOLUTION: The antifalsifying medium having a volume hologram layer recording interfering fringes by at least irradiating with laser light and being exposed to light, an electronic see-through information layer where electronic see-through information is recorded, and a base material film is characterized in that the information recorded in the electronic see-through information layer is read out by irradiating the light of which one or more of an incident angle and an incident wavelength are different relative to hologram regenerating illuminating light for regenerating the image recorded in the volume hologram layer. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
