Embodiments and Examples of the Invention
Embodiments and examples of the present invention will be described with reference to the drawings. First, in the hologram ID key system of the present invention, it is assumed that a hologram ID key in which a hologram of a circular barcode having ID information composed of a plurality of bits is transferred to at least one location on the surface of the key is used. 1A and 1B are external views of an embodiment of a hologram ID key used in a hologram ID key system of the present invention, wherein FIG. 1A is a front view, and FIG.
[0009]
The figure shows a hologram ID key in which a plurality of recesses 4 for transferring the hologram 3 are provided on the surface of the key 2 and the hologram 3 is transferred in the recess 4 by a circular bar code having ID information composed of a plurality of bits. 1 is shown. The shape of the hologram 3 is circular, and the size and the depth of the concave portion 4 may be arbitrary. Further, the transfer position and the number of the holograms 3 may be arbitrarily set, and may be transferred to either the front surface or the back surface.
[0010]
FIG. 2 is a principle diagram of a circular barcode slit for recording and detecting a hologram using a circular barcode. A circular barcode 8 in which a plurality of thin slits 9 and thick slits 10 are concentrically arranged on a film 7 is formed. A transmission hole 11 for transmitting the reference light by the laser light 6 is formed in the center of the circular barcode 8. The circular barcode 8 is equivalent to a general linear barcode 12 if the narrow range of the dotted line in the figure is viewed, and a plurality of bits can be obtained by changing the number, interval and order of the narrow slits 9 and the thick slits 10. Can be recorded. In FIG. 2, the circular bar code 8 is shown by a solid black line for easy understanding. However, in practice, the solid line portion is formed transparent and the other portions are masked with black or the like. The laser beam 6 is applied to the surface of the film 7 in a direction perpendicular to the surface.
[0011]
As a principle of recording a hologram using a circular barcode, the laser beam 6 transmitted through the film 7 is focused on the focal point as object light containing information on the circular barcode 8, and the laser beam 6 is directly incident on the focal point as reference light. Then, interference fringes are generated on the focal point by the object light and the reference light, and are recorded as the hologram 3. The hologram 3 of a circular bar code is transferred to the concave portion 4 of the key 2 using the principle.
[0012]
As a principle of detecting a hologram by a circular bar code, when a laser beam 6 is irradiated on a film 7 on which a circular bar code 8 in which a plurality of narrow slits 9 and thick slits 10 are arranged concentrically is formed, a circular shape transmitted through the film 7 is obtained. The object light containing the information of the bar code 8 is focused on the hologram 3 on the focal point, and reflected light is generated. Then, the reflected light is introduced into the hologram detection unit 14 to detect a correlation output, that is, the presence or absence of a correlation peak. Here, when the correlation peak is detected, the ID pattern information of the film 7 matches the hologram information by the circular bar code, and the ID information can be detected.
[0013]
As the ID information, for example, 2 ⁸ = 256 IDs can be identified from the hologram 3 using a circular bar code having 8-bit ID information. Then, necessary ID information can be recorded on the hologram ID key 1 by transferring the hologram 3 onto the surface of the key 2 at at least one location. In FIG. 1, the holograms 3 are transferred to four places on the surface of the key 2. However, it is not always necessary to collate all four holograms 3, and the holograms 3 as dummy may be transferred. When a plurality of persons individually use the hologram ID key 1, different ID information is transferred to the hologram 3 or the pattern of the transfer position is changed, and the ID assigned to the user of each hologram ID key 1 is changed. By judging the information or the transfer position information by the server 22 or the security management center 24 described later, it is possible to manage who locked or unlocked and when.
[0014]
Although a conventional key groove 5 is engraved on the side surface of the key 2, the hologram ID key 1 of the present invention is a key system that can unlock by collating and matching the hologram ID. The unlocking operation is not essential, and the key groove 5 may be omitted.
[0015]
As described above, in order to transfer the hologram 3 to the key 2, a circular barcode slit for recording and detecting a hologram using a circular barcode and a laser beam are necessary, so that duplicate key duplication at a duplicate key store or the like is difficult. Or impossible.
[0016]
