Abstract

PURPOSE:To prevent identification information from easily being reproduced and to preclude forging by recording fake identification information and real identification information on an optical recording medium repeatedly as a diffraction pattern. CONSTITUTION:The fake identification information and real identification information are stored repeatedly on the optical recording medium as the diffraction pattern. Then interference fringes formed with recording light and reference light are recorded on a photosensitive plate 9 and when the photosensitive plate 9 is irradiated with the laser light outputted by a laser oscillator 1 through a lens 10, the light is diffracted by the diffraction pattern recorded on the photosensitive plate 9 as the interference fringes to reproduce a stereoscopic image of a bar code pattern recorded as a repro duced image. When this is viewed in one direction of the diffraction, a bar code image 7' which is the real identification information can be reproduced and a virtual image of a bar code pattern 8 which is the fake identification information is eliminated. Consequently, the recording medium is hardly forged, so an accident due to the forging is precluded.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an identification information recording medium in which false identification information and true identification information are multiplexed on one recording medium to make it difficult to copy, and the same. This article relates to an identification method using a recording medium to identify an individual or a product, and a full-text payment method.

〔overview〕

The present invention prevents forgery by preventing easy duplication by using a recording medium in which false information and true information are optically recorded multiple times as an identification information recording medium. It is something to do.

[Conventional technology]

Traditionally, so-called ID cards for identifying individuals are:
A magnetic card system was used in which identification information was magnetically recorded on a magnetic stripe. In addition, barcode systems were used to identify products and the like. In other words, a sheet with a barcode printed on it is attached to a product at a supermarket, etc., and this barcode is optically read by a reading device at the store of the store, the sold product is identified, the sales amount is counted, and the product is distributed to multiple stores. It was used as a so-called POS system that can instantly process information such as sales amounts and product types. In addition, in libraries, etc., sheets with barcodes printed on them are attached to books, and the barcodes attached to the books are read by optical readers.
This system identifies books and performs lending and return processing using an information processing device.

[Problem that the invention seeks to solve]

However, the above-mentioned identification information recording method has a problem in that it is easily forged.

In other words, in the magnetic card system, magnetically recorded information can be easily read by a magnetic reader, so forging a magnetic card is easy for anyone with some technical knowledge in the field. This has led to social incidents involving counterfeit magnetic cards.

For this reason, methods such as retinal pattern registration and fingerprint registration have been proposed to identify the person, but identifying the person using this method requires a complex information processing method and special It was not something that could be easily used except for its intended purpose.

Furthermore, in the product identification method using the barcode method, since the object to be identified is simply a printed matter with a black and white barcode pattern, it is possible to easily duplicate or forge the same barcode. For this reason, for example, even if a duplicated barcode is used illegally, there is a problem in that the reading device cannot recognize the forgery. In particular, if a large number of illegal barcodes are used, problems will arise in product management at product stores that use the POS system.

As described above, the conventional identification information recording method had the problem that it could be easily forged.6 The present invention solves the problems of the prior art described above.
To provide a recording medium that can prevent an identification information recording medium from being forged or duplicated and used illegally by recording false identification information and true identification information on the same recording medium, and to further utilize this recording medium. The purpose is to provide a personal identification method and fee payment method.

[Means for solving problems]

The first feature of the present invention is an identification information recording medium in which false identification information and true identification information are multiplex recorded as a diffraction pattern on an optical recording medium. , the false identification information and the true identification information are configured in a deep pattern, and interference fringes of the pattern of the false identification information and the true identification information formed by a recording beam and a reference beam are recorded on an optical recording medium. can be done. Moreover, a barcode can be used as identification information.

The second feature is that a recording medium in which false identification information and true identification information are recorded multiplexed as a diffraction pattern on the surface of an optical recording medium is used as a personal identification card.

The third feature is that a recording medium in which false identification information and true identification information are recorded multiple times as a diffraction pattern on the surface of an optical recording medium is used as a product identification mark.

Furthermore, the fourth feature is that the user is issued with a recording medium in which false identification information for identifying the individual user and true identification information are recorded multiplexed as a diffraction pattern on an optical recording medium. The identification information recorded on the recording medium is optically read when the user enters the bath and when the user exits the bath, and based on the read identification information of the user, the user's usage fee is calculated and the user's account is calculated. The purpose is to deduct usage fees for each user.

[Effect]

The present invention uses optical technology that can optically record a three-dimensional image to multiplexly record false identification information and true identification information on one optical recording medium. This optical recording medium uses so-called holography technology to multiplexly record false identification information and true identification information, and detects only the true identification information from the optically reproduced image to identify the person or identify the product. Make identification. This recording medium contains false identification information and cannot be easily duplicated.

Further, the recording medium on which this identification information is recorded is used to distinguish between true identification information and false identification information using an optical detection device, and only the true identification information is extracted and used to identify the person or the product.

Furthermore, in the present invention, this identification information is used in the method of paying admission fees. In other words, each individual is issued a recording medium on which this personal identification information is recorded, and when entering the room, a detection device reads the true identification information recorded on this recording medium to identify the individual, and this information is also used when leaving the bath. It is used in a system that reads the true identification information recorded on the recording medium, calculates the usage fee for this individual, and automatically debits the usage fee from the account of the individual who uses it to pay the fee.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show an example of the principle of recording and reproducing the identification information recording medium of the present invention. FIG. 1 shows the principle of recording identification information, and FIG. 2 shows the principle of reproduction. ing.

The embodiment shown in FIGS. 1 and 2 uses holography technology to arrange false identification information and true identification information three-dimensionally,
This is an example of recording this as interference fringes on one recording medium.

In FIG. 1, reference numeral 1 denotes a laser oscillator, and the light output from the laser oscillator 1 is separated by a half mirror 2 into recording light and reference light. The recording light is reflected by a mirror 3 and passes through a lens 5 as a plane wave to form a barcode pattern 6 of false identification information and a barcode pattern 7 of true identification information.
is irradiated.

The barcode pattern 6 of this false identification information and the true barcode pattern 7 are arranged at a distance in the depth direction. The recording light reflected by the barcode patterns 6 and 7 is transmitted to the photosensitive plate 9.
leading to.

The reference light separated by the half mirror 2 is irradiated onto the photosensitive plate 9 via the mirror 4 and the lens 6, and forms interference fringes with the above-mentioned reflected recording light. Interference fringes formed by this recording light and the reference light are recorded on the photosensitive plate 9, and a deep barcode pattern 6.7 is recorded. The interference fringes recorded on the photosensitive plate 9 act as a diffraction grating for reproduction light when a recorded image is reproduced.

FIG. 2 explains the reproduction of the barcode pattern recorded on the photosensitive plate 9. As shown in FIG. When the laser beam output from the laser oscillator 1 is irradiated onto the photosensitive plate 9 through the lens lO, it is diffracted by a diffraction pattern recorded as interference fringes on the photosensitive plate 9, and a barcode pattern is recorded as the reproduced image. A 3D image of is reproduced. If this three-dimensional image is viewed from only one direction of diffraction, only the barcode pattern 7', which is a virtual image of the barcode pattern that is the true identification information, can be reproduced.
A virtual image of the barcode pattern 6, which is false identification information, can be eliminated.

Therefore, according to this embodiment, it is possible to multiplexly record false identification information and true identification information on the photosensitive plate 9, which is one recording medium, and reproduce only the true identification information from the recorded identification information. Can be done.

In addition, in these FIGS. 1 and 2, the barcode pattern 6.
7 is arranged flat and deep, and a recording light is irradiated on it, and the reflected light is recorded on a photosensitive plate 9. A barcode pattern is recorded on the photosensitive plate 9 by irradiating a laser beam on the photosensitive plate 9 and using the transmitted light. However, with holography technology, instead of using the transmission type photosensitive plate 9, it is possible to record on a reflection type holography. Further, although it is assumed that the barcode patterns 6 and 7 are recorded at the same time, it is of course possible to record them separately in time on the same photosensitive plate 9.

Further, in this embodiment, a barcode pattern was used as the identification information to be recorded, but other patterns may be used as long as they can be optically separated and recognized and can be used as an identification pattern. . For example, a fingerprint-like pattern may be used, or characters or symbols may be recorded multiple times.

Furthermore, in the above description, the barcode pattern 7 of true identification information and the barcode pattern 6 of false identification information are separated and only the virtual image 7' of the true barcode pattern 7 is reproduced.
It is also possible to mix true identification information and false identification information into each barcode pattern 6.7 and separate and identify the true identification information and false identification information from the two reproduced images. be.

Next, an embodiment of the personal identification method using the above-mentioned holographic identification information recording medium will be described with reference to FIGS. 3 and 4, showing a configuration diagram of an identification detection device. The system shown in Figure 3 uses transmission type holography.
The figure shows an example using reflection-type holography.

First, using the recording method shown in FIG. 1, each individual is issued with an identification card 21 in which false identification information of a barcode and true identification information are recorded using holographic technology.

The identification and detection device shown in FIG. 3 includes a laser oscillator 22 that outputs coherent reproduced light, a light receiver 23 that receives the reproduced light of the laser oscillator 22 and converts it into an electrical signal, and a light receiver 23 that receives the reproduced light of the laser oscillator 22 and converts it into an electrical signal. It consists of a determiner 24 that determines the holder of the identification card 21 from the output electrical signal.

To explain the operation, the holder of the identification card 21 inserts the identification card 21 into a predetermined position between the laser oscillator 22 and the light receiver 23. The light receiver 23 receives reproduction light of only the true identification information from the false identification information and the true identification information recorded on the identification card 21, and converts it into an electrical signal. The reproduction light of only the true identification information is extracted by the light receiver 23 so that the angle of incidence of the reproduction light on the light receiver 23 is adjusted so that only the reproduced image at the position where only the true identification information is recorded is received in advance. This can be done by arranging a light receiving element at a position where only the reproduced image of the identification information is diffracted and emitted. In addition, the light receiving element is placed at a position where the false identification information and the true identification information can be reproduced, respectively, and the determining device 24
It is also possible to determine whether the identification information is true identification information or false identification information.

As the light receiver 23 for receiving such a reproduced holographic image, an imaging device using a light receiving element such as a CCD can be used.

The reproduced image received by the light receiver 23 and converted into an electric signal is output to the judger 24, where it is compared with the true identification information recorded in advance for each individual and sent to the identification card 21. The owner of the item is determined. This is the same as normal barcode identification.

FIG. 4 is a configuration diagram when reflection holography is used with the identification card 21. Reproduction light output from the laser oscillator 22 is reflected by the identification card 21, received by the light receiver 23, and photoelectrically converted for judgment. It is output to the device 24. The identification card 21 is determined from the signal manually input by the judge 24.
Determine the owner of the . In FIG. 4, the identification card 21
The light reflected by the broken line represents diffracted light corresponding to a reproduced image of the false identification information diffracted by the holography of the identification card 21.

In this way, it is possible to use holography, in which false identification information and true identification information are multiplexed recorded, as a personal identification method.

When this identification card 21 is used as a passport, it is not easy to forge it, so it is possible to prevent unauthorized entry and exit from the country due to unauthorized use of the passport, and it is possible to reliably catch unauthorized entry and exit from the country.

Furthermore, a sheet-like identification card on which this false identification information and true identification information are multiplexed can be used as an identification mark for products. In this case, send this identification card to the POS
It is used by pasting it on products in the same way as the system barcode. Then, by passing the identification card affixed to this product through an identification detection device placed at the sales point, the multiple recorded identification information from the identification card is optically reproduced, and the reproduced identification information is Extract the true identification information inside,
It is used for payment at sales points and product management in POS systems.

Next, FIG. 5 shows a system configuration diagram of a method for paying admission fees using the above-mentioned holographic recording medium as a recording medium for identification information. Figure 5 shows a system in which the user information recorded on a recording medium issued to each user is read at each expressway gate, and the usage fee is automatically debited from a bank account. This system will be explained using an example.

First, the system configuration for an expressway in this embodiment will be explained. There is a host computer 31 at the center of this expressway system, and this host computer 31 is
Connected to this host computer is (7) a terminal device 34 for registering new user registration information, deletion registration information, accident information such as loss, etc., and a user file 32 for storing information of each registered user. Pretend that there is a
Furthermore, it is possible to output to a printer 33 as an output device.

Further, the host computer 31 is connected to a bank computer via a communication line 35, and is further connected to local CPUs 41, 52, etc. of each gate via a communication line 36.

Game) A is a local CPU 41 connected to the host computer via a communication line 37, and this local CPU
A reading device 42 is connected to the local CPU 41 to read the identification information recorded on the identification recording medium 38 attached to the vehicle 37 used for public bathing, and a reading device 42 is also connected to the local CPU 41 and reads the identification information recorded on the identification recording medium 38 affixed to the vehicle 37 that is used for bathing. A display board 43 for displaying instructions and a warning speaker 44 are provided.

Gate B also has a reading device 52 on the local CPU 51.
In this configuration, a display board 53 and an alarm speaker 54 are connected.

Next, the procedure for issuing the identification recording medium 38 in this system will be explained with reference to FIG.

First, an application from a user is accepted (S61), and the application is registered in the user file 32 of the host computer 31 using the terminal device 34 (S62). When a user is registered, the user's bank account number is also registered so that automatic withdrawals can be made from the bank account (S 6
3). When this user registration work is completed, an identification recording medium 38 in which false identification information and true identification information are recorded multiple times as identification information for each user is issued to the applying user (364).

The user attaches the issued identification recording medium to a predetermined position of the vehicle and starts using it (S65).

Next, the processing operations performed on the system side when a user uses this expressway toll payment system will be described with reference to a flowchart shown in FIG.

Information on time and entrance gate code is provided by the local CPU 41.
The data is transmitted from the host computer 31 to the host computer 31 via the communication line 36 (373). The host computer 31 searches the information sent from Gate 8 to see if accident handling information such as loss has been registered for the user (
S74).

If accident processing information is registered, the identification recording medium 38 cannot be used on the expressway, so the local CPU 41 must be notified of the existence of the accident processing information.
75) The local CPU 41 displays the notification that passage is not permitted on the display board 43 and issues an alarm through the alarm speaker 44 (376).

When there is no accident processing information, passing permission information is notified to the local CPU 41, and the local CPU 41 displays the information on the display board 43.
Passage permission is displayed on the screen (77).

2 transmits the read identification code, that is, the user code, date of use, time, and hot spring gate code information to the host computer 31 (S83).

The host computer 31 calculates the usage fee for this user based on the data sent from gates A and B (S84). This calculation result is then notified to gate B (S85), and gate B displays the fare on the display board 53 (S86). This calculation result is also notified to the computer at the bank, and the usage fee is debited from the bank account (S87).

The usage fee for each user is determined by the host computer 31.
The tabulation results are outputted to the printer 33, and the printed usage charges are mailed to each user to inform them of the monthly usage charges (389).
).

In this way, it is possible to optically read identification information from an identification recording medium that is difficult to forge and to pay fees by automatic account debit. Further, since the identification recording medium can be read optically and without contact, it is possible to reliably read the identification recording medium with the identification device even when a vehicle passes at high speed.

In this example, payment of expressway usage fees was explained as an example, but the payment system is not limited to expressway usage fees, but can be used for other entrance fee payment systems, and credit cards can also be used. It can also be used for payment.

〔Effect of the invention〕

In addition, by using this recording medium as a personal identification card, individuals can be identified with a simple configuration.
When used on products, it can be used as an identification mark for POS systems that is difficult to counterfeit, and it is possible to detect unauthorized use.

In addition, since true identification information is extracted optically and without contact, it is possible to identify vehicles passing at high speed, and the range of application of the identification method can be expanded.

Furthermore, by using this recording medium for user identification, it is possible to build a fee payment system that automatically debits accounts, creating a payment system that is convenient for users and less likely to be fraudulently used. It is possible to do so.
