    摘要： A thermosensitive ink layer 102 is composed of a thermochromic material which changes from black to a transparent state and is formed on a substrate 101 made from a PET film by heating. A cholesteric liquid crystal layer 103 on which a hologram 105 of an appropriate form is formed on the cholesteric liquid crystal layer is mounted thereon. At ordinary temperature, the thermosensitive ink layer 102 exhibits a property of light absorption and a property of selective reflection and a color shifting of the cholesteric liquid crystal layer 103 are observed. The thermosensitive ink layer 102 becomes transparent by heating and the figure 104 on the substrate 101 is also visible. The determination of the authenticity thereof is performed by utilizing the change of view. Therefore, the anticounterfeiting effects are superior to those of the discrimination techniques using conventional techniques, and this enables articles to be distinguished easily and reliably.

    摘要： Provided is an economical identification system suitable for use on commercial products which is difficult to duplicate, and highly identifiable. The system includes an identification medium having a high-polymer cholesteric liquid crystal material applied thereon. The high-polymer cholesteric liquid crystals selectively reflect a certain wavelength, and this wavelength changes with the change in the incident angle of the light. The liquid crystals also have the property to circularly polarize the reflected light in either sense. By taking advantages of such properties, it is possible to provide a highly identifiable structure which, however, is highly difficult to illicitly duplicate. In particular, by forming the reflective layer of a hologram with high-polymer cholesteric liquid crystals, the hologram can be used as an identification medium which is highly difficult to duplicate but easy to identify with a machine.

    摘要： A number of high-permeability magnetic elements are dispersed in a scanning region of a checking object. A core of a processing apparatus is provided with an exciting coil and a sensor coil. When a bias magnetic field is applied to the core, and the scanning region is passed in the vicinity of a gap, the permeability of the gap varies depending on the density of the magnetic elements, so that a magnetic flux passing through the core changes. A detection signal corresponding to the change of the magnetic flux is detected by means of the sensor coil. This detection signal is converted into a cipher code and then recorded in a code indicator section of the checking object. In checking the authenticity of the object, a detection signal obtained by scanning the scanning region by means of the processing apparatus and a code for collation obtained by decoding the cipher code recorded in the code indicator section are compared, and it is concluded that the checking object is real when the detection signal and the collation code correspond to each other.
