Description

The present invention relates to a method for preventing counterfeiting of contact media used for a touch screen. More specifically, the present invention relates to a method for preventing counterfeiting of contact media, which suppresses a new counterfeiting act by issuing a warning against counterfeiting when trying to obtain desired characteristic information with counterfeit contact media.

Conventionally, as a method of recording information on a contact medium and reading it electronically, a plurality of small regions made of a conductive material at positions predetermined for each characteristic information and the plurality of small regions are formed on one surface of the contact media. In order to form a conductive region made of a conductive material that makes contact with a human, which is necessary for recognizing the above, and further to conduct the conductive regions that make contact with each other and / or the human. In addition, a capacitive touch screen that can recognize multi-touch by electrically connecting with a thin line made of a conductive material recognizes the positions of the plurality of small areas, and uses this position information for characteristics. There is a method of using information.

Several proposals have been made for this type of contact media system, including Patent Document 1.

The contact media used in this contact media recognition system has a shape typified by a card and generally has two surfaces. The card-shaped contact medium is often formed by laminating a plurality of sheet-shaped base materials, and is generally formed by laminating two sheets. The final formed contact media has two sides. Often referred to as the front and back surfaces.

As the base material of the contact media, plastic, paper, wood-based material, glass, ceramic, cloth, leather, a combination thereof, or a composite material obtained by laminating them can be used. On the non-conductive surface of the base material, a plurality of small regions made of a conductive substance, a conductive region that makes contact with a human being, and a thin bond line made of the conductive substance are formed at positions predetermined for each characteristic information. Can be used as a contact medium.

When a plurality of small areas made of a conductive substance of a contact medium, a conductive area made of contact with a human being, and a bonding line made of a conductive substance are formed by printing a conductive ink using screen printing technology. There are many. A method of forming a plurality of small regions made of a conductive material of a contact medium, a conductive region that makes contact with a human, and a bonding line by pasting a metal foil is also known. In order to protect the plurality of small areas, the conductive area that makes contact with a human, and the bond line from scratching when touched, it is common to protect the plurality of small areas with another base material or the like.

As an example of the use of the contact media configured as described above, a portrait, a figure, a portrait, a figure, etc. By printing a map, text information, etc., and bringing the contact medium into contact with a capacitive touch screen capable of recognizing multi-touch, the desired characteristic information can be obtained.

Designs such as highly designed portraits and figures can be printed on the front and / or back of the contact media configured as described above to enhance the collectible value of the contact media (card), but the contact media Since different characteristic information can be obtained by changing the positions of the plurality of small regions made of the conductive material in the above, even if the printed design is the same, the characteristic information obtained by changing the positions of the plurality of small areas made of the conductive material can be obtained. It is possible to produce a rarity as a contact card that can obtain its own value or different characteristic information, and further enhance the collectible value.

However, in the case of the layered structure of the contact media, a plurality of small regions made of a conductive substance may be visible when light is transmitted. Moreover, as described above, a plurality of small regions made of a conductive material, a conductive region made of contact with a human, and a bonding line made of a conductive material can be printed with conductive ink using screen printing technology or a metal leaf. Therefore, if the value is simply found only in the characteristic information and the position information of the small area made of the conductive material can be easily visually recognized, it is easy to forge only the position of the small area. There was a problem that characteristic information could be obtained.

As a method for solving the above problems, as illustrated in Patent Document 2, it has been proposed to conceal a plurality of small regions made of a conductive substance with a darker color non-conductive ink. There is.

The problem in this case is that if the conductive ink is colored and has a high transmission density, a darker non-conductive ink must be selected, and the ink is applied to substantially the entire surface of the contact medium. Must. It may also affect the color of the appearance of the contact media.

Further, depending on the selection of the conductive ink, due to the characteristics of the conductive ink, the conductivity may not be sufficiently exhibited unless the thickness of the ink is increased, and the conductive substance is optically applied to the upper layer of a plurality of small regions. Even when a simple concealing layer and / or a physical protective layer is provided, a plurality of small regions made of the conductive material appear as protrusions on the outer surface, and the position information of the plurality of small regions made of the conductive material can be easily obtained. It had the drawback of being visible.

Furthermore, when trying to obtain the desired characteristic information with a forged contact media, if the position information of a plurality of small areas made of conductive substances is different from the original position information, the desired characteristic information cannot be obtained illegally. Although it is not possible, if the original position information is obtained by repeatedly forging the contact media, there is a drawback that the desired characteristic information is also obtained illegally as a result.

An object of the present invention is a method for preventing counterfeiting of contact media used for a capacitive touch screen capable of recognizing multi-touch, and when an attempt is made to obtain desired characteristic information with the contact media counterfeited by the counterfeiting, counterfeiting is performed. The purpose is to deter new counterfeiting by directing users to a page that displays a warning against.

In order to solve the above problems, the present invention has the following means. That is, it is a method for preventing counterfeiting of contact media used for a capacitive touch screen capable of recognizing multi-touch, and a plurality of conductive substances composed of at least one surface of the contact media at a position predetermined for each characteristic information. In a contact medium in which a conductive small region and a conductive bond line made of a conductive material that conducts the small regions are formed, a non-conductive small region made of a non-conductive material is formed in the same direction of the contact media. Is formed on the conductive coupling line, and instead of the non-conductive small region by counterfeiting, a conductive small region is formed at the same position to conduct the conductive small region to obtain characteristic information. This is a method for preventing counterfeiting of contact media, which is characterized by directing a user to a page displaying a warning against.

On one surface of the contact media, at least at a position predetermined for each characteristic information, a plurality of conductive small regions made of a conductive material, a conductive coupling line made of a conductive material that conducts the small regions, and a non-conductive material. The non-conductive small region made of a non-conductive material in the contact media (hereinafter, also referred to as a genuine contact media) formed on the conductive bond line is non-conductive. Therefore, in the capacitive touch screen that can recognize multi-touch, the non-conductive small area is not recognized as position information at all, and the non-conductive small area is large, the non-conductive small area is mutual, or the conductive small area is used. Regardless of the positional relationship with the non-conductive small region, only the position of the conductive small region made of a conductive material is correctly recognized.

On the other hand, in the genuine contact media, the small region including the non-conductive small region and the contact media in which all the conductive bond lines are formed of a conductive substance (hereinafter, may be referred to as counterfeit contact media) have a small non-conductive property due to counterfeiting. The small conductive region formed at the same position instead of the region has different positional information from the original small conductive region formed at a position predetermined for each characteristic information, that is, the small non-conductive region in the genuine contact medium. A small area whose area has been replaced with a conductive small area by counterfeiting is also added to the position information, and even if it is recognized by a capacitive touch screen that can recognize multi-touch, it contains position information different from that of genuine contact media. By doing so, the application software in the touch screen determines that it is counterfeit, and while refusing to connect to the server of the site that provides characteristic information in genuine contact media, it leads to a page that displays a warning against counterfeiting. Not only is it impossible to obtain characteristic information (characteristic information obtained by genuine contact media), but also the fact that the counterfeiting has been performed is displayed on the touch screen, so that further counterfeiting is suppressed.

According to the present invention, it is a method for preventing counterfeiting of contact media used for a capacitive touch screen capable of recognizing multi-touch, and when trying to obtain characteristic information in genuine contact media by counterfeit contact media, a warning against counterfeiting is displayed. By directing to the page, new counterfeiting can be deterred.

The method for preventing counterfeiting of the contact media of the present invention will be described in detail.
The contact media according to the method for preventing counterfeiting of contact media of the present invention is used for a capacitive touch screen capable of recognizing multi-touch, and is composed of one sheet or two or more laminated sheets. A plurality of conductive small regions made of a conductive material (hereinafter, a conductive small region made of a conductive material is simply referred to as a conductive small region) on one surface of the contact media at least at a position predetermined for each characteristic information. (There is also), a conductive bond line made of a conductive substance that conducts the small conductive regions to each other (hereinafter, the conductive bond line made of a conductive substance may be simply referred to as a conductive bond line) and non-conducting line. A contact medium in which a non-conductive small region made of a conductive material (hereinafter, a non-conductive small region made of a non-conductive material may be simply referred to as a non-conductive small region) is formed on the conductive coupling line. Is.

The contact media (genuine contact media) according to the present invention includes a plurality of conductive small regions at positions predetermined for each characteristic information, and a conductive coupling wire for conducting the conductive small regions with each other, as well as with a human being. A conductive region (hereinafter referred to as a handle portion) made of a conductive material that makes contact with a human is required, but if the handle portion is formed as a conductive region that makes contact with a human, it is classified by characteristic information. It may be formed as an extension of a conductive coupling line for conducting a small conductive region formed at a position other than a predetermined position or a small conductive region formed at a predetermined position according to characteristic information. That is, when the handle portion is held by a human and touched by a capacitive touch screen capable of recognizing multi-touch, the handle portion may be a conductive region that is not in contact with the touch screen, and its shape is sufficient. The shape is not limited, such as a lump or a linear shape having substantially the same shape as the small conductive region, a mesh shape combining the linear shapes, or a combination thereof.

Hereinafter, the contact media (genuine contact media) according to the method for preventing counterfeiting of the contact media of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the genuine contact medium 1 according to the present invention is a contact medium used for a capacitive touch screen capable of recognizing multi-touch, and is previously attached to one surface of the genuine contact media 1 according to characteristic information. Non-conductive in the same direction of the genuine contact media 1 in which a plurality of small conductive regions 3, a conductive region (handle portion) 2 made of a conductive material, and a conductive coupling line 4 are formed at a determined position. It is a contact medium formed by forming a small region 5 on the conductive coupling line 4.

The small conductive region 3 in the genuine contact media 1 according to the present invention, together with the conductive coupling line 4 and the conductive region (handle portion) 2, is used as a contact medium for the touch screen in advance according to the characteristic information in the touch screen. It suffices to have enough conductivity to be recognized as a determined position. On the other hand, the non-conductive small region 5 may have conductivity (non-conductive) to the extent that it cannot be recognized as a position determined in advance for each characteristic information.

In the genuine contact media 1 according to the present invention, for example, at least a small conductive region 3, a conductive region (handle portion) 2, and a conductive coupling line 4 may be formed on one surface of the genuine contact media 1. .. Further, the non-conductive small region 5 is formed in the same direction as the surface on which the small conductive region 3 or the like is formed, that is, on the same surface as the surface on which the small conductive region 3 or the like is formed, or the contact media 1 is formed. It suffices that the surface on one side (that is, the same direction) on which the small conductive region 3 and the like are formed and the surface on which the small non-conductive region 5 is formed are in a laminated relationship.

When the non-conductive small region 5 and the conductive small region 3 and the conductive coupling line 4 are formed on the same surface, both may be formed directly on the genuine contact media 1, or the genuine contact media 1 is A sheet obtained by forming both of them on another non-conductive sheet may be bonded to the genuine contact medium 1. When the non-conductive small region 5, the conductive small region 3 and the conductive coupling line 4 and the like are formed on another surface on one side of the contact media 1, that is, in the same direction, the conductive small region 3 and the like are formed. It suffices if the surface on which the non-conductive small region 5 is formed and the surface on which the non-conductive small region 5 is formed are in a laminated relationship, and even if the formed surface such as the conductive small region 3 is laminated on the formed surface of the non-conductive small region 5. , The non-conductive small region 5 may be laminated on the forming surface such as the conductive small region 3. Further, in the case of a laminated relationship, not all of the non-conductive small regions 5 may be formed on the same surface, and a part of the non-conductive small regions 5 may be formed on a formed surface such as the conductive small regions 3.

Further, at least one of the non-conductive small regions 5 may be formed on the conductive coupling line 4, but it is preferable that the non-conductive small regions 5 do not overlap with the conductive small regions 3, and the deterrent against counterfeiting can be further enhanced. In addition to the non-conductive small region 5 on the conductive coupling line 4, it is preferable that the small region 3 and the conductive coupling line 4 are also formed at a position where they do not overlap with each other. On the other hand, not only when the non-conductive small region 5 is not formed, but also when the non-conductive small region 5 is formed in a manner that cannot be equated with at least the conductive small region 3, even if it is forged. The desired characteristic information of the genuine contact media 1 can be obtained, and at least it does not serve as a deterrent to counterfeiting. Therefore, it is desirable that the non-conductive small region 5 has the same shape and thickness as the conductive small region 3, and the surface provided with the non-conductive small region 5 or the like is protected by another base material or the like. Even in the case of media, the non-conductive small region 5 preferably has the same color as the conductive small region 3 in consideration of the case where the base material is peeled off by a counterfeiter.

The size of the small conductive region 3 in the genuine contact medium 1 according to the present invention is not particularly limited as long as it is recognized as a predetermined position for each characteristic information on the touch screen. In addition, the shape of the small conductive region 3 is a circular shape, a polygonal shape of a triangle or more, a star shape, an amorphous mass, a shape in which these are stretched or contracted in one direction or more, and a combination of two or more of these. The shape can be mentioned. Further, the shape of the non-conductive small region 5 is the same as that of the conductive small region 3, which is a circular shape, a polygonal shape having a triangle or more, a star shape, an amorphous mass, and a shape obtained by stretching or contracting these in one direction or more. In addition, a shape in which two or more of these types are combined can be mentioned. Further, in one contact medium, a plurality of types of shapes of the conductive small region 3 and the non-conductive small region 5 may be used in consideration of design and the like, and in that case, the non-conductive small region 5 may be used. A shape similar to that of the small conductive region 3 is preferable.

If the conductive coupling line 4 is too thick, there is a possibility that a predetermined position for each characteristic information in the conductive small region 3 connected to the conductive coupling line 4 may be misidentified. (Thin) is desirable.

Further, the conductive coupling wire 4 is linear, and examples thereof include a straight line or a curved line and a shape in which these are combined. If the conductive coupling line 4 has an angle or is partially composed of a curve having a small radius of curvature, it may be mistaken as a small conductive region 3 on the touch screen, that is, a position predetermined for each characteristic information. Therefore, it is preferable that the conductive coupling line 4 does not include a curve having a small angle or radius of curvature. Further, if there is an end portion of the conductive coupling wire 4 that is not connected to the small conductive region 3, it is located at the position of the handle portion that makes contact with a human or is connected to the conductive region 2 provided in the handle portion. It is necessary to be. Further, in order to enhance the deterrent against counterfeiting, in addition to the conductive coupling wire 4, the non-conductive region 2 connected to at least the conductive region 2, the conductive small region 3 or the non-conductive small region 5 made of a conductive substance is connected. It is preferable to have a non-conductive bond wire made of a sex substance. Similar to the relationship between the non-conductive small region 5 and the conductive small region 3, the non-conductive coupling line preferably has a line width, thickness, and color that can be equated with the conductive coupling line 4.

Next, the material used for the contact media according to the present invention and the method for producing the contact media will be described.
As the base material of the contact media according to the present invention, plastics such as polyethylene, polypropylene and polyethylene terephthalate, paper, composite materials in which they are laminated, glass, ceramics, cloth, leather, or a combination thereof can be used. However, the contact media of the present invention is made into a card shape, and when used, the forming surface such as a small conductive region is in close contact with the touch screen, and the conductive region of the handle is supple so that it can be made non-contact from the touch screen. A material that exhibits a high degree of distortion is preferable, and plastic, paper, and a composite material obtained by laminating them are preferable. The thickness of the base material is arbitrary, but if it is too thin, the durability will be inferior, and if it is too thick, it will be inconvenient to use and store. ..

Further, in order to impart functionality to the base material of the contact media according to the present invention, a plurality of layers can be formed on the front and back surfaces of the base material. For example, an easy-adhesion layer, an antistatic layer, an adhesive layer, an ink receiving layer, a scratch-resistant reinforcing layer, a water-resistant layer, and the like. A plurality of these can be arbitrarily selected with respect to the required functions.

The method of forming a conductive small region, a conductive bond line, or the like on the base material of the contact media according to the present invention is a method of printing conductive ink using screen printing technology, based on a good conductive metal foil. A method of forming by sticking to a material and a printing method by an inkjet method using silver ink are also known, but in the present invention, any of them may be used, and at least a small conductive region and a conductive bond line are formed by another method. You may let me.

Further, depending on the selection of the conductive ink, due to the characteristics of the conductive ink, the conductivity may not be sufficiently exhibited unless the thickness of the ink is increased, that is, the position may not be recognized as a predetermined position according to the characteristic information. As a result of thickening the small conductive region, the small conductive region appears as a convex portion on the surface even when an optical concealing layer or / or a material protective layer is provided on the upper layer of the small conductive region. In some cases, the positional relationship of the small conductive regions can be visually recognized. In such a case, it can be dealt with by increasing the thickness of the ink of the non-conductive material.

The method for forming the non-conductive small region on the base material of the contact medium according to the present invention may be handwriting, but it is preferably formed by printing. The printing method is generally known, for example, letterpress printing, offset plate printing, gravure printing, flexographic printing, screen printing, inkjet printing, and the like, but is not limited thereto. The ink for forming a non-conductive subregion, the ink is preferably equal to or greater than 1 × 10 ⁸ Ω · cm in resistivity volume resistivity after drawing specifically (after drying), the one corresponding to the print method You can choose. It is more preferable that the color of the print is close to the color of the conductive substance region. The print density (optical reflection density) is preferably the same as that of the small conductive region.

The contact medium according to the present invention is composed of one sheet or two or more laminated sheets, but in the same direction of one base material, a small conductive region, a conductive bond line and a small non-conductive area. When forming regions, the order of formation is arbitrary.

In the above case, the method of further adhering the base material on the surface on which the conductive small region, the conductive bond line and the non-conductive small region are formed is a known method, that is, the conductive small region and the conductive bond. A method in which an adhesive layer is further formed on the surface on which the wire and the non-conductive small region are formed and another base material is bonded, the surface on which the conductive small region, the conductive bond wire and the non-conductive small region are formed. A method of forming an adhesive layer on another base material, a method of adhering with an adhesive material such as double-sided tape, and the like can be mentioned, but the present invention is not limited thereto. The same applies to the case where the contact medium of the present invention is composed of two or more sheets, and the same applies to the case where the conductive small region, the conductive coupling wire and the non-conductive small region are formed in separate layers. Is.

It should be noted that the significance of forming the non-conductive small region is remarkable when the non-conductive small region or the like is exposed on the outermost surface on the side where the non-conductive small region and the conductive small region are formed with reference to the contact medium. Since it is lowered, in order to optically conceal the small conductive area and protect the small conductive area from scratches during use, an opaque protective layer should be provided to conceal and protect the small conductive area optically and physically. Is essential. The protective layer may be covered by printing, an appropriate opaque base material may be attached, or printing may be performed on an appropriate transparent base material to make the protective layer opaque.

Further, it is also possible to form a colored layer having a transmission concentration of 0.7 or more on the surface on which the conductive small region, the conductive bond line and the non-conductive small region are formed, and use it as the contact medium of the present invention. Further, the contact medium of the present invention finally has a card shape constituting the front surface and the back surface, and on the front surface and the back surface, for example, information including characters, symbols and images, anti-counterfeiting measures such as holograms, stickers and the like. It can be pasted or the like.

Finally, the method for preventing counterfeiting of the contact media of the present invention will be described with reference to the drawings.
First, the contact media shown in FIG. 1 has a plurality of conductive small regions 3 made of a conductive material at least at positions predetermined for each characteristic information on one surface of the contact media, and conductivity that conducts the small regions with each other. Assuming that the genuine contact medium 1 is formed with the conductive bond line 4 made of a material, when the genuine contact medium 1 is brought into contact with the capacitive touch screen 11 as shown in FIG. 3, characteristic information is obtained. Characteristic information can be obtained by conducting the small conductive region 3 at a predetermined position separately. On the other hand, since the non-conductive small region 5 made of the non-conductive material is non-conductive, the non-conductive small region 5 is not recognized as position information at all by the capacitive touch screen capable of recognizing multi-touch. Correctly recognizes only the position of the conductive small region 3 made of a conductive material, regardless of the amount of the non-conductive small region, the non-conductive small regions, or the positional relationship between the conductive small region and the non-conductive small region. ..

As shown in FIG. 2, in the contact media (counterfeit contact media) 10 in which the small conductive region 53 is formed at the same position as the non-conductive small region 5 in the genuine contact media 1 shown in FIG. Since the non-conductive small region 5 of the genuine contact media 1 becomes the conductive small region 53 due to counterfeiting, the non-conductive small region 5 is brought into contact with the capacitive touch screen 11 as in FIG. When trying to obtain information (FIG. 4), since the small conductive region 53 is formed at a position different from the position predetermined for each characteristic information, even if it is recognized by the touch screen 11, the different position information is obtained. Is included, the application software in the touch screen 11 determines that it is counterfeit, and while refusing to connect to the server 12 of the site that provides characteristic information, it leads to a page that displays a warning against counterfeiting. Not only is it impossible to obtain the characteristic information of the period (characteristic information obtained by the genuine contact media 1), but also the fact that the counterfeiting has been performed is displayed on the touch screen 11, so that the counterfeiter is informed that the counterfeiting act has been detected. , Further counterfeiting is deterred.
