摘要： Provided is an identification medium with which it is possible to view a latent image having a plurality of colours, even when a polarization filter is positioned away from the identification medium. The identification medium is provided with a cholesteric liquid crystal layer (102) as a specific polarization reflection layer for reflecting light of a specific polarization state, and an optical anisotropic layer (106) having refractive index anisotropy is disposed in a position overlying the cholesteric liquid crystal layer (102). An image (A) which is composed from a region having optical anisotropy different from that of the periphery thereof is formed in the optical anisotropic layer (106). When the identification medium (100) is viewed directly, the image (A) cannot be seen as the effect of the optical anisotropy cannot be seen. When viewed through a circular polarization filter, the image (A) can be seen in specific colours due to the effect of the optical anisotropy.

摘要： A genuineness detecting film (10) includes at least a reflecting film (11) having a circularly polarized light selectivity such that it reflects only a left-handed or right-handed circularly polarized light out of incident lights and generates a reflected light. On the reflecting film (11), a hologram forming portion (11a) is provided. The hologram forming portion (11a) reflects the same circularly polarized light as the reflected light in a direction different from the direction in which the reflected light travels and thereby to form a hologram image. Sensors disposed in different positions sense the reflected light from the reflecting film (11) and the hologram image from the hologram forming portion (11a), respectively.

摘要： A large number of magnetic polymer elements (12) are distributed at random in a base material (11) of a object (1) to be checked. Each magnetic polymer element (12) includes an element main body formed of a high-molecular material, such as an acrylic resin, and magnetic metal powder contained therein. The base material (11) is formed mainly of paper, and the magnetic polymer elements (12) are incorporated together with wood pulp fibers in the base material (11). The elements (12) and the fibers are tangled with one another in three dimensions. Indication data (17) including figures, symbols, etc., such as post position numbers and bet numbers on betting tickets for publicly-managed gambling, are printed on the object (1). The indication data (17), along with a proper output signal obtained in accordance with the state of distribution of the magnetic polymer elements (12), are enciphered according to specific rules for enciphering, and are recorded in a code indicator section (6) by means of a recording medium, such as a magnetic stripe which is magnetically readable or a bar code which is optically readable.

摘要： An optical identification label (3) consisting of an area of hologram (10) or diffraction grating which is transparent to visible light but reflects incident light with a specific reflective directivity. By identifying the reflectivity directivity, it is possible to identify the authenticity of the label (3) and, hence the object to which the identification label is affixed. The fact that the identification label (3) is transparent to human eyes offers a strong discouraging effect on potential forgers. Further, the pattern of the reflected light may be used for encoding data.

摘要： An object to be checked contains a large number of magnetic polymer elements (12) scattered at random. Each of magnetic polymer elements (12) is made up of an element main body (13) formed of a high molecular material, and magnetic metal powder (14) contained in the element main body (13). The magnetic polymer elements (12) are integrally incorporated in paper and tangled with the wood pulp fibers of the paper three-dimensionally. In the manufacturing process of the object, a processing apparatus magnetically scans the magnetic polymer elements (12) incorporated in the scanning region of the object while moving the scanning region at a predetermined speed, converts a detection signal obtained by the magnetic scan into a cipher code, and records the cipher code in a code indicator section. In the authenticity checking process, the processing apparatus magnetically scans the magnetic polymer elements (12) once again, and a detection signal obtained thereby is collated with the cipher code recorded in the code indicator section. When the detection signal and the cipher code agree with each other, the object is determined as being authentic.
