    摘要: In one embodiment of the present invention, an information identification device, an information identification method, and an information identification system each of which can maintain a high security level and which can be used for a long time without any restrictions on use conditions are realized. An ID identification system includes: an ID identifying medium containing a rare-earth complex; and an ID identification device for identifying identification information corresponding to the rare-earth complex. The ID identification device includes: a light source for irradiating, with exciting light, an ID identifying medium containing a rare-earth complex; a measurement section for receiving light emitted from the ID identifying medium, and for measuring spectral intensities of the light; a computation section for computing a ratio of spectral intensities at different wavelengths among the spectral intensities thus measured; and an identification section for identifying identification information corresponding to the ratio thus computed.
