Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a certificate issuing and authentication system using a security medium having a function of preventing forgery such as gift certificates, securities and evidence securities.

[0002]

2. Description of the Related Art In recent years, various certificates including prepaid certificates such as gift certificates and gift certificates, securities such as banknotes and checks, cards such as credit cards, and securities such as evidence certificates such as driver's licenses. Forgery and alteration have become a problem. Therefore, there have been proposed a security medium capable of discriminating an authentic certificate as a forgery or a fake one, a method for discriminating a genuineness by using information of such a security medium as an index, and an apparatus for carrying out the method.

For example, a method has been proposed in which a watermark is put in a security medium as an index for authenticity recognition, or a hologram transfer foil is attached to a part of the surface of the security medium. According to these methods, confirmation of authenticity is mainly performed by visually observing this mark.

Further, for example, by distributing small pieces such as fine metal fibers and fine magnetic elements on the certificate base material itself, the security of the form contained in the certificate base material that can be detected by electromagnetic means. A medium, a determination method using such a security medium as an index, and an apparatus for implementing the method are also known. According to the security medium, the discrimination method, and the discrimination device, by the microwave or the magnetoelectric conversion element, the metal as the identification mark is present in the certificate base material itself, that is, the security medium existing over almost the entire area constituting the certificate. The presence of a fiber or the like was detected by detecting the presence or absence of a marker as an index and the distribution state thereof.

[0005]

However, in the case of determining whether or not the certificate is authentic by using the above-mentioned security medium, there are the following problems. .

For example, in the case of a security medium which is supposed to be visually inspected by providing a watermark or hologram layer on the surface of the certificate, the skill of the person in charge of discriminating is required from the viewpoint of the certainty, stability and speed of the inspection. Depends on the technology of. Furthermore, there is a problem that operating costs are high because human resources have to be allocated.

Further, in a security medium in which a metal fiber or the like as an identification mark is present and the presence or absence thereof is used as an index, the metal fiber or the like is mixed in the certificate base material itself, and therefore it may be necessary for discrimination in some cases. There is a problem in that it is not possible to mix in an amount sufficient to obtain various detection signal intensities, and it is not possible to increase discrimination accuracy. Further, if the base material of the certificate itself is forged, there is a problem that it is meaningless to confirm the authenticity.

The present invention has been made in view of the above problems, and an object of the present invention is to easily and surely determine whether or not a certificate including a security medium is authentic. It is to provide a certificate issuing and authenticating system that uses a security medium that has a configuration capable of performing the above and that is easy to manufacture and operate, and a method for implementing the system.

[0009]

In order to solve the above-mentioned problems, the inventors of the present application apply the certificate with security medium suitable for application to the system and method of the present invention, especially the security. Proposing a medium.
This security medium has a structure in which an electromagnetically sensitive substance, which is a small piece to be detected, is irregularly dispersed in a heat-meltable substance as a base material.

Here, "irregularly dispersed" means that, in each security medium fixed to each certificate, the unit volume of the detected small piece mixed in the base material, that is, the heat-meltable substance. Although the number of contained particles per unit, that is, the distribution density is almost the same, the three-dimensional distribution position of the detected small pieces dispersed in the base material, that is, the existence position, is biased for each security medium. means. Therefore, since there is virtually no distribution of the detected small pieces, the distribution state of the detected small pieces specific to each security medium is detected by, for example, an electromagnetic means, and then the distribution state is detected. It is possible to determine that the security medium is authentic, that is, that the certificate to which the security medium is fixed is not a counterfeit product or a counterfeit product by using the information of 1.

Further, the "front surface" of the certificate in the present invention is an area in which predetermined items of the certificate can be written, and may be any surface on which the above-mentioned security medium can be provided. Therefore, the front surface here includes so-called front and back surfaces of the certificate.

The certificate issuing and authenticating system of the present invention is an authenticating system for authenticating a certificate provided with the security medium having the above-mentioned structure, and has the following structure.

That is, a certificate issuing device comprising a security medium attaching unit for attaching a security medium to a certificate, a certificate issuing unit for issuing a certificate with a security medium, and a first reading unit for reading characteristic data of the security medium. The registration / verification means comprises registration / verification means connected to the certificate issuing device via a communication line, and a database connected to the registration / verification means. A certificate issuing / registering device for registering as registration data in the database; a second reading unit for reading the characteristic data of the security medium of the certificate with security medium; and a verification result notifying unit,
The read characteristic data read by the second reading unit is transmitted to the registration / collation unit, the collation result of the read characteristic data and the registered data is received from the registration / collation unit as the authentication result, and the collation result notification unit displays the recognition result. It has a recognition terminal for notifying.

According to this structure, it is possible to quickly and surely perform the work of confirming various certificates, which has been time-consuming by a skilled person, with a simple structure.

Therefore, it is possible to construct and operate the system very easily and at low cost.

Further, in various application procedures that require a certificate, even if the base material itself of the certificate is forged, it is true that the characteristic data of the security medium, that is, the security data is forged and reproduced. Since it is impossible, it is possible to surely determine whether or not each certificate is forged, and to deal with it swiftly.
Therefore, it is possible to provide a certificate issuing and authenticating system having higher security and higher efficiency than the conventional one.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. It should be noted that in the drawings, the size, shape, and arrangement relationship of each constituent component are only schematically illustrated to the extent that the present invention can be understood, and the numerical conditions described below are merely examples. .

First, the structure of the certificate with security medium applied to the present invention will be described with reference to FIG. FIG. 1A is a plan view schematically showing a configuration example of the certificate 10 and the security medium 14 provided therein. Further, FIG. 1B is a cross-sectional view schematically showing a cross section taken along dashed-dotted line AA ′ in FIG. (1) Description of Security Medium and Certificate As the material of the certificate 10 applicable to this security medium 14, if the material that is not sensitively detected by the means used for detecting the detected small piece,
The thickness and other properties are not limited as long as the object of the present invention is not impaired.

Therefore, as the material of the base material 12 of the certificate 10, paper, polyvinyl chloride, polycarbonate,
It is preferable to use a non-conductive material such as plastic or resin made of polyester or the like. The base material 12 of the certificate 10 is preferably made of a paper material made of wood pulp or synthetic pulp.

The security medium 14 has a structure in which the electromagnetically sensitive substance 14a constituting the small piece to be detected is irregularly dispersed in the heat fusible substance 14b as the base material.
The detected small pieces 14a provide characteristic data unique to the security medium 14, that is, security data.

On the other hand, the small piece 14a to be detected is made of a material that can be detected by electromagnetic means, for example, an electromagnetically sensitive substance such as a metal fiber, a metal foil, a magnetic element and a metal-coated plastic fiber. Good to do.

For example, the material of the small piece 14a to be detected is preferably stainless steel.

The shape of the small piece 14a to be detected is preferably fibrous, but the size in the major axis direction, that is, the ratio of the length to the size in the minor axis direction, that is, the diameter, width or thickness. However, the larger one is preferable. Therefore, the detected small piece 14a is preferably a finer fibrous small piece.

Therefore, the electromagnetic sensitive material 14a of the security medium 14 is made of, for example, stainless fiber,
It is preferable that the average diameter is 6 to 10 μm and the length is about 5 mm.

As the heat-fusible substance 14b constituting the security medium 14, a wax-like substance selected from the group including paraffin wax, carnauba wax and ester wax can be used. Alternatively, a thermoplastic resin selected from the group including vinyl chloride resin, ethylene resin, and acrylic resin can be used instead of the wax-like substance. Also, instead of the wax-like substance alone or the thermoplastic resin, a mixture of the wax-like substance and the thermoplastic resin can be used.

Regarding the physical properties suitable for the heat-fusible substance 14b, the object of the present invention is to take into consideration the specifications of the security medium 14 to be manufactured, the properties of the certificate to be applied, the durability of the manufacturing apparatus described later, and the like. Can be determined within a range that does not impair It is preferable to use a heat-fusible substance having a property of melting or softening, preferably in the range of 70 ° C to 130 ° C.

The security medium 14 can be formed as an independent structure in itself. Therefore, the security of the certificate 10 can be ensured by adding the security medium 14 to the certificate 10 already issued and used. Further, unlike the prior art, since the distribution data of the small pieces in the entire security medium 14 is used, more reliable security of the certificate 10 is secured. Further, the security medium 14 can be made less expensive.

The certificate 10 to which the security medium 14 of the present invention is applied may be a newly manufactured certificate or a certificate already used and distributed.

As the heat-meltable substance 14b,
It is preferable to select and use a substance that becomes colorless and transparent after the manufacturing process.

By using such a substance, the function as the security medium 14 can be imparted without impairing the essential aesthetic appearance even in a certificate in which aesthetics is a problem.

Even if the security medium 14 is colorless and transparent, its presence can be visually confirmed by its gloss, so that the certificate 1 which does not exist where it should exist.
It is of course possible to distinguish 0 as a counterfeit.

Next, a method of fixing the security medium 14 to the certificate will be described with reference to FIG.

FIG. 2A is a schematic partial sectional view showing an example in which the security medium 14 is configured in the form of the transfer ribbon 18.

FIG. 2B is a plan view of a principal part schematically showing a structural example of the thermal transfer recording device 20 for carrying out the method for manufacturing the security medium 14.

In the first step, the security medium 14 is prepared by mixing the electromagnetically sensitive substance 14a, which is a small piece to be detected, with the heat-fusible substance 14b as a base material to form a mixture thereof. The mixing ratio is preferably set such that the detected small pieces are appropriately dispersed in the base material, and the distribution state of the individual detected small pieces can be appropriately recognized as meaningful identification information. Next, in a second step, the obtained liquid phase mixture is applied onto the base film 16 and then dried to manufacture the transfer ribbon 18 having the solid phase mixture.
In this case, the solid phase mixture may be fixedly formed on the sheet-shaped base film 16 and then cut into a ribbon, or the solid phase mixture may be fixedly formed on the ribbon-shaped base film 16. Good. Finally, in a third step, the obtained transfer ribbon 18 is wound around, for example, a reel, and then the transfer ribbon 18 is wound around the thermal transfer recording device 20. After that, the thermal transfer head 2 is placed on the predetermined portion of the certificate 10.
Thermal transfer is performed by the action of 2. In this way, the security medium 14 can be provided on the surface of the base substrate 12 of the desired certificate 10.

As described above, the security medium 14 uses a base film or a base material of a certificate as a support, and the process of manufacturing the security medium 14 in layers on the support is extremely simple, so that the manufacturing cost is reduced. Contribute to a significant reduction.

The mixture obtained in the first step is preferably 5 to 2 stainless steel fibers when the small piece to be detected is stainless steel fiber as the electromagnetic sensitive substance 14a.
At a ratio of 0% by weight, that is, the base material, the heat-meltable substance 1
It is preferable to mix 4b as 95 to 80% by weight.

The structure of the transfer ribbon 18 will be described with reference to FIG.

The transfer ribbon 18 for forming the security medium 14 is fixed on the upper surface of the base film 16 by applying a heat-meltable substance 14b in which the small pieces 14a to be detected which essentially constitute the security medium 14 are dispersed. It is composed of

At this time, the amount of the mixture applied on the base film 16 should be such that a sufficient detection signal can be obtained to achieve the object of the present invention when the security medium 14 is used. See below). For example, when stainless steel fiber is used as the electromagnetic sensitive material, the amount is preferably 5 to 15 g / m ² .

As the base film 16, films made of various materials can be used as long as the object of the present invention is not impaired.

For example, a polyimide tape, a polyester film and the like can be mentioned, but preferably a polyester film is used.

The transfer ribbon 18 may be assembled in a cassette and finished as a module, for example, similarly to the form actually used in a printer for a word processor or a personal computer.

The transfer of the security medium 14 from the transfer ribbon 18 onto the base material 12 in the third step is performed in a solid phase with a desired size suitable for a predetermined portion of the surface of the base material 12 of the certificate 10. Thermal transfer is performed by melting the mixture with the thermal transfer head 22. Further, as described above, for example, the transfer ribbon 18 is finished in a cassette shape and incorporated in the thermal transfer recording device 20 as a module, whereby the operation of the system including the security medium 14 can be facilitated and the device can be downsized. it can.

An apparatus for carrying out the method of manufacturing the security medium 14 will be described with reference to FIG.

The thermal transfer recording apparatus 20 includes a feeding reel 24, a take-up reel 26, a thermal recording head 22 and a platen roller 28. This thermal transfer recording device 2
It can be said that 0 is an application of the configuration of a thermal transfer printer used in a word processor, a personal computer or the like which has been conventionally used in principle. Therefore, although not described in detail, further components other than the conventionally used configuration may be included.

The operation of the thermal transfer recording device 20 will be described more specifically below with reference to FIG.

First, the feeding reel 24 and the take-up reel 2
The transfer ribbon 18 is hung over the sheet 6. Then finally certificate 1
The base material 12 completed as 0 is arranged immediately above the base material side of the transfer ribbon 18 and on the lower surface side of the platen roller 28. As the certificate 10, for example, a seal stamp certificate issued by a public institution or the like is assumed, but the certificate 10 is not limited to this.

Here, the base material 12 may be a certificate that is already completed one by one, for example, is already used or is ready to be used,
It may be a simple base material such as a continuous roll before completion.

Therefore, after the security medium 14 is formed on the base material 12, a specific prescribed content may be printed on the certificate 10.

The transfer ribbon 18 is pressed against the platen roller 28 with an appropriate pressure by the operation of the thermal transfer head 22.

At the same time, the base material 12 is transferred by the rotation of the platen roller 28, and when it reaches the preset installation position of the security medium 10, the control circuit (not shown) controls the thermal transfer head 22 to an appropriate temperature. While generating heat, the transfer ribbon 18 is pressed from the base film 26 side to the surface of the base substrate 12.

Then, the solid-phase compound, that is, the small piece to be detected 14 formed by coating the base film 16 in layers.
a, for example, a heat-meltable substance 14 in which an electromagnetic sensitive substance is dispersed
The mixture of b is melted by the heat generated by the thermal transfer head 22 and is sequentially transferred onto the surface of the base material 12.

The heat-fusible substance 14b is solidified by contacting with air and cooling to form a mixture as a solid phase layer.

Through the above steps, the security medium 14
Is firmly fixed on the surface of the base substrate 12.

In the thermal transfer recording apparatus 20 for forming the security medium 14 on the surface of the base material 12 of the certificate 10, the thermal transfer head 22 is provided with a degree of freedom so that the installation position can be set freely. Or base material 1
By giving the second arrangable area a degree of freedom within a range not impairing the object of the present invention, it is possible to flexibly deal with a plurality of types of certificates 10 without substantially changing the configuration of the thermal transfer recording device. Is possible.

Therefore, according to the method of forming the security medium 14, the certificate 10 or the base material 12 is appropriately positioned on the surface of the base material 12 by the position of the transfer ribbon 18 or the operation of the thermal transfer head 22. Can be formed and added without depending on the form, properties, and the like.

When a transfer sheet in which a solid phase mixture is formed in layers on a sheet-like film is used instead of the transfer ribbon described above, the structure of the thermal transfer recording device 20 is changed and a partial area on the transfer sheet is changed. It is sufficient to have a structure capable of sequentially performing thermal transfer.

Next, with reference to FIG. 3 and FIG. 4, the apparatus and its embodiment for using the security medium 14 to determine whether the security medium 14, that is, the certificate 10 is authentic or not. Explain.

FIG. 3 shows a reading device 30 for reading information on the security medium 14 fixed to the certificate 10.
It is a partial plan view showing an outline of.

Examples of the electromagnetic means for detecting the electromagnetic sensitive substance of the security medium 14 include a microwave sensor and a magnetoelectric conversion element. In this embodiment, electromagnetic waves are used as electromagnetic waves. An example of detecting a sensitive substance will be described.

The reading device 30 for using the security medium 14 includes a front transfer roller 32 including an upper roller 32a and a lower roller 32b, and a rear transfer roller 34 including an upper roller 34a and a lower roller 34b. It includes a plurality of sets of transfer rollers including the microwave sensor 36, and a controller 38 connected to the microwave sensor 36 and controlling them.

The front transfer roller 32 and the rear transfer roller 34 sandwich the completed base material 12 as the certificate 10 or the certificate 10 in a specific direction.
That is, it is for transferring in the direction of arrow B in FIG.

The microwave sensor 36 includes a microwave transmitter 36a and a microwave detection sensor 36b for detecting a reflected wave of the emitted microwave reflected by the electromagnetic sensitive material. This reading device 30
As the microwave sensor 36 that can be preferably used, a conventional microwave transmitter and microwave detection sensor can be used. For example, preferably New Japan Radio Co., Ltd.
It is preferable to use NJR4211, etc. manufactured by the company.

In this embodiment, a stainless fiber is used as the detected small piece 14a of the security medium 14, and the security medium 14 is irradiated with microwaves by the microwave oscillator 36a that constitutes the microwave sensor 36 to generate a reflected output. An example in which is detected by the microwave detection sensor 36b is shown.

Referring to FIG. 3, this security medium 1
A method of detecting the characteristic data of No. 4, that is, security data will be described.

The security medium 14 is moved in the direction of arrow B along with the transfer of the certificate 10. Then, the microwave sensor 36 whose operation is controlled by the control unit 38
By the microwave transmitter 36a constituting the above, microwaves are sequentially radiated from the right end side to the left end side of the security medium 14 transferred in the arrow B direction. The reflected output from the stainless fibers, which are the detected small pieces 14a dispersed in the security medium 14, is sequentially detected by the microwave detection sensor 36b provided near the microwave transmitter 36a.

The detected reflected output is amplified by an amplifier (not shown) and further converted into a digital signal by an A / D converter (not shown).

These detection results are registered in a database built in computer hardware (not shown) connected to the control unit 38 directly or via a communication line. Further, this data can be displayed and output on a monitor (not shown) connected to the control unit 38 or computer hardware.

An example of the detection result is shown in FIG.

FIG. 4 is a graph showing an example of the detection result data output by reading the certificate 10 to which the security medium 14 is added by the above-mentioned reading device 30.

The horizontal axis of the graph represents time, that is, the position of the security medium 14 being read. The vertical axis is
Amplify the amplitude of the read signal with an amplifier, and after that,
The signal strength after A / D conversion is shown.

The security medium is the microwave sensor 36.
Is plotted, that is, the signal intensity after A / D conversion detected for each medium scanning position is plotted, and adjacent plots are connected by a straight line.

As a waveform suitable for the detection data of the security medium 14, as shown in this example, a waveform in which the vertical widths of the signal intensities of adjacent plots are large,
It is preferable from the viewpoint of security accuracy.

Therefore, the concentration of the small piece 14a to be detected with respect to the heat-fusible substance 14b is such that the height difference between the respective points becomes large so that the output waveform repeatedly engraves high peaks and deep valleys. , It is better to select an appropriate concentration.

The shape of the security medium 14 is preferably rectangular, but may be elliptical or the like as long as the object of the present invention is not impaired.

Assuming that the security medium 14 has a rectangular shape, focusing on its size, the length in the short axis direction, that is, the width of the security medium 14 of the present invention is determined by the microwave sensor 36 used. Of the microwave detection sensor 36b, that is, the width of the opening of the microwave detection sensor 36b may be set, and may be set appropriately within the range not impairing the object of the present invention. It is better to make the width narrower than the width.

With this configuration, even if, for example, the center line of the opening of the microwave detection sensor 36b and the center line of the security medium 14 of the present invention deviate to the range of 1/2 of the difference between these widths, the microwave Wave detection sensor 36b
Can output almost the same reading result.
Therefore, some margin can be provided for the adjustment when the microwave sensor 36 is attached to the reader 30 and the transfer mechanism of the certificate 10 and the like can be provided, and strict precision is not required. Manufacturing, installation and operation can be made easier.

The length of the rectangular security medium 14 in the long axis direction is determined by the required data accuracy and reading point,
That is, it is determined by the detection pitch (interval) of the microwave detection sensor 36. For example, assuming that the microwave detection sensor 36b having a detection pitch of 2 mm is used to detect 32 points, a length of about 64 mm is required. As the number of points to be detected increases, the number of characteristic points of the detected waveform increases, and the waveform becomes complicated, so that the individual identification accuracy of the security medium 14, that is, the security is improved. However, on the front surface and / or the back surface of the certificate 10, it is necessary to write predetermined description items, or it is necessary to write them after adding the security medium, and that the detection pitch of the sensors is different depending on the model. Considering that, the length is 10 mm to 10
It is preferably in the range of 0 mm.

The thickness of the security medium 14 can be appropriately set within a range that does not impair the object of the present invention. However, due to the nature of certificates, it is considered that a plurality of certificates are often overlaid and stored. Therefore, the thickness is preferably 5 μm to 20 μm in a range not bulky during storage.

The characteristic data read in this way,
That is, it is generally preferable to store the security data in the database of the certificate issuer or a trusted external third party when the certificate is issued.

When the certificate is issued and distributed, and it is necessary to confirm the authenticity of the certificate due to use, payment, etc., the characteristic data of the security medium 14 is read again, and the characteristic data of the security medium 14 is read at the time of issuance and registered. It suffices to check the registered data.

At this time, it is inevitable that the re-read characteristic data will be slightly different from the registered data registered and saved at the time of issuing the certificate due to individual difference of the microwave detection sensor and the like. In such a case, the correlation coefficient between the registered data and the collated characteristic data is calculated. If this is a predetermined value or more, it is determined that the security medium is a genuine security medium, that is, a true certificate, and a predetermined value or more. If the value of is not shown, it is determined to be a fake certificate.

The predetermined value here is a value that is appropriately determined so as to satisfy the error rate and the correct answer rate set according to the strength of security required for each certificate.
