Disclosed herein is a highly identifiable material that includes a physical body with an original spectral signature and an artificial tag incorporated on the physical body, which modifies the original spectral signature of the body. The artificial tag is configured to emit passively at least two spectral signatures in response to a source of energy received by the artificial tag. The spectral signatures are signals of interest for imaging technology. The artificial tag spectrally codifies all the information necessary to detect and/or identify a first predetermined feature of the highly identifiable material. The artificial tag may include a spatial pattern, and the spatial pattern may include a predetermined combination of the at least two spectral signatures. Also disclosed herein is a method for manufacturing such a material and a method for identifying such a material.
