Description

  The present invention relates to a product authentication display body, a product authentication device, a product authentication system, and a product authentication method used for authenticating whether or not a product is a genuine product.

  In recent years, there are increasing cases in which food production areas are disguised and sold, or low-quality counterfeit products are sold as fake products. In addition, such impersonation and imitation have become very sophisticated, and various product authentications have been proposed in the security industry in order to eliminate these frauds.

  For example, as a typical example of product authentication, an IC chip is attached to a product, and identification information such as the place of origin, origin, and distribution process is written to the IC chip as needed, and the identification information is read from the IC chip by a reader device as necessary. By reading out, the traceability of the distributed products is performed.

  However, the above-described product authentication has a problem that the manufacturing cost of the product increases because the IC chip attached to the product is expensive. In addition, since a process for attaching an IC chip, which is an electronic component, to a product is required, there is a concern that the manufacturing process becomes complicated. Further, it is sufficient to determine whether the product is genuine at the time of authentication, and when detailed information regarding the distribution channel is not required, the IC chip is excessively equipped and wastes in terms of resources as well as costs.

  On the other hand, in the decoration industry different from the security industry, decorations such as characters and designs are applied to products such as exterior panels of game machines and game machines, advertising bodies, ornaments, display devices, etc. was there. In such decoration, a technique of a decoration display body that improves the decoration effect by causing an enlarged virtual image such as a character or a pattern to appear upward or downward from the surface of various products has been known. Is disclosed.

  The decorative display body disclosed in Patent Document 1 is formed by two-dimensionally arranging a plurality of colored pixels on the back surface of a sheet-like or plate-like transparent material with the directionality of each pixel. A plurality of convex lens-shaped light condensing elements are formed on the surface of the transparent material in a two-dimensional array with the same directionality as the pixel patterns. The pixel pattern and the light condensing element pattern are formed so that the arrangement pitch of each pixel and the arrangement pitch of each light condensing element are different in each direction.

  However, such a decorative display body is conventionally used only for the purpose of improving the decoration effect in the decoration industry, and is not used for other purposes in the industry besides the decoration industry. It was. In addition, since such a decorative display body has the effect of decorating an enlarged virtual image only when the pixel pattern and the light condensing element pattern are overlapped with each other through the transparent material, the pixel pattern and the light collecting pattern are respectively formed on the front and back surfaces of the transparent material. It was assumed that the photoelement pattern was integrally formed.

  The present applicant has been made in view of the above-described technical background, and can display a product authentication display body, a product authentication device, a product authentication system, and product authentication that can easily and reliably authenticate a product. It aims to provide a method.

  In order to achieve the above-mentioned object, the present invention provides a pixel pattern formed by two-dimensionally arranging a plurality of pixels on the surface of a product or an accessory of a product with the directionality of each pixel, A sheet-like or plate-like transparent material provided separately from the product or an accessory of the product, and a plurality of light condensing elements on the surface of the transparent material so that each light condensing element has a directivity. A light condensing element pattern that is two-dimensionally arranged at a different arrangement pitch from the pixels, and the light condensing element patterns have the same directionality with respect to each other through the transparent material above the pixel pattern. When the product is arranged, an enlarged virtual image of the pixel for authenticating whether or not the product is a genuine product appears above or below the transparent material. It is characterized by being.

  According to this, since the enlarged virtual image appearing above or below the transparent material can function as authentication information for authenticating whether or not the product is a genuine product, the operator can use pixel information as authentication information. By confirming the presence or absence of a magnified virtual image or the sharpness, it is possible to easily and reliably authenticate whether or not the product is genuine. Further, since the pixel pattern is simply formed by printing or the like for the product or the product accessory, the manufacturing cost of the product can be kept low. Furthermore, the pixel pattern cannot be visually confirmed without a predetermined condensing element pattern. In addition, if the pixel and condensing element arrangement pitch and diameter, the thickness of the transparent material, etc. are not set accurately, the pixel will be enlarged. Since the virtual image does not appear, it is possible to maintain technical difficulty against imitation of the product authentication display body.

  In addition, the pixel pattern may be arranged above or below the transparent material while the height or depth of the enlarged virtual image of each pixel gradually changes as the arrangement pitch of adjacent pixels gradually changes. A three-dimensional enlarged virtual image group that appears and has a gently curved surface as a whole may be configured. According to this, since a three-dimensional enlarged virtual image group having a gentle curved surface appears as a whole, an enlarged virtual image of a pixel can function as more advanced authentication information. Difficulty can be increased.

  Further, the light condensing element pattern is formed by gradually changing the arrangement pitch of the adjacent light condensing elements so that the enlarged virtual image of each pixel gradually changes in height or depth. A three-dimensional enlarged virtual image group that appears above or below the transparent material and has a curved surface as a whole may be configured. According to this, since a three-dimensional enlarged virtual image group having a gentle curved surface appears as a whole, the enlarged virtual image of a pixel can function as more advanced authentication information. Difficulty can be increased. In addition, it is not necessary to set a change in the pixel arrangement pitch, and it becomes easy to set a complicated pixel shape. Therefore, variations in the design of the enlarged virtual image of the pixel can be easily increased.

  The pixel pattern may be formed of a fluorescent paint that emits light when irradiated with UV light. According to this, since the pixel pattern emits light by irradiating the product authentication display body with UV light, the presence or absence of light emission and the luminous intensity of the pixel pattern function as authentication information in addition to the authentication information by the enlarged virtual image. Can do.

  The pixel pattern may be provided with a phosphorescent layer that absorbs ultraviolet rays such as a fluorescent lamp and sunlight and emits light in a dark place in the background. According to this, since the background of the pixel pattern emits light by disposing the product authentication display in a dark place, in addition to the authentication function based on the enlarged virtual image, the presence or absence of light emission and the luminous intensity of the pixel pattern background are authenticated information. Can function as.

  In addition, the product authentication apparatus according to the present invention includes the product authentication display body, an imaging unit that captures an enlarged virtual image of the pixel by the product authentication display body, and an enlargement of the pixel captured by the imaging unit. An authentication unit that authenticates whether or not the product is a genuine product based on a virtual image and an output unit that outputs an authentication result by the authentication unit.

  According to this, the authentication work of the enlarged virtual image of the pixel can be automated, and authentication errors can be reduced. In addition, even if the enlarged virtual image of a pixel is complicated by complicating the shape and pattern of the pixel, the authentication means in the computer can sufficiently authenticate the enlarged virtual image of the pixel, so that more advanced authentication information is given to the product. can do.

  In the product authentication system according to the present invention, the imaging unit and the output unit are provided in a portable information terminal, and the authentication unit is provided in a server computer on a network, and the pixel imaged by the imaging unit. An enlarged virtual image is transmitted from the portable information terminal to the server computer via the network, and an authentication result by the authentication unit is transmitted from the server computer to the portable information terminal via the network. .

  According to this, the operator can easily authenticate the product by connecting to the server computer from the portable information terminal through the network, and the cost is kept low because it is not necessary to provide a dedicated device. be able to. Further, since the system can be updated by updating the authentication means in the server computer, the product authentication system can be easily maintained.

The product authentication method according to the present invention is a product authentication method using the product authentication display body,
The light condensing element pattern formed on the surface of the transparent material is arranged with the same direction as each other through the transparent material above the pixel pattern formed on the surface of the product or an accessory of the product, An enlarged virtual image of the pixel for authenticating whether or not the product is a genuine product appears above or below the transparent material.

  According to this, since the enlarged virtual image appearing above or below the transparent material can function as authentication information for authenticating whether or not the product is a genuine product, the operator can use pixel information as authentication information. By confirming the presence or absence of a magnified virtual image or the sharpness, it is possible to easily and reliably authenticate whether or not the product is genuine. Further, since the pixel pattern is simply formed by printing or the like for the product or the product accessory, the manufacturing cost of the product can be kept low.

<First Embodiment>
Next, a first embodiment of a product authentication display body according to the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the product authentication display body 1 has a pixel pattern formed by two-dimensionally arranging a plurality of pixels 21 with the direction of each pixel 21 on the surface of a product G. 20, a sheet-like or plate-like transparent material 10 provided separately from the product G, and a plurality of light condensing elements 31 on the surface of the transparent material 10 with the directivity of each light condensing element 31 arranged. And the light condensing element pattern 30 that is two-dimensionally arranged at an arrangement pitch different from that of the pixel 21, and both the pixel pattern 20 and the light condensing element pattern 30 are formed by printing.

  As shown in FIGS. 2 and 3, the pixel pattern 20 is provided on the surface of the product G by arranging a plurality of pixels 21 in a two-dimensional manner with the alignment of the pixels 21. Specifically, the pixel pattern 20 is linearly arranged at an arrangement pitch p in a direction in which the pixels 21 are inclined at an angle of 45 ° with respect to the horizontal direction (hereinafter referred to as “x direction”), and the x direction The pixels 21 are arranged two-dimensionally in a matrix form by linearly arranging them in an orthogonal direction (hereinafter referred to as “y-direction”) at an arrangement pitch p. Note that the pixel 21 of the present embodiment has a pixel diameter of 1.0 mm and an arrangement pitch p of 1.1 mm.

  As shown in FIGS. 2 and 3, the light condensing element pattern 30 is formed by two-dimensionally arranging a plurality of convex lens-shaped light condensing elements 31 with the same directionality as each pixel 21 of the pixel pattern 20. Is formed. Specifically, the condensing element pattern 30 is linearly arranged at an arrangement pitch q in a direction in which the condensing element 31 is inclined by an angle of 45 ° with respect to the horizontal direction (hereinafter referred to as “x direction”), The light condensing elements 31 are two-dimensionally arranged in a matrix by linearly arranging them at an arrangement pitch q in a direction orthogonal to the x direction (hereinafter referred to as “y direction”). The light condensing element pattern 30 is set so that the arrangement pitch q of the adjacent light condensing elements 31 is smaller than the arrangement pitch p of the pixels 21. In addition, the condensing element 31 of this embodiment is set so that the diameter of the condensing element 31 is 0.95 mm and the arrangement pitch q is 1.05 mm.

  In addition, rectangular frame lines 22 and 32 having the same size are provided on the periphery of the pixel pattern 20 and the periphery of the light condensing element pattern 30, respectively. Thus, when the frame line 22 and the frame line 32 are matched when the pixel pattern 20 and the light condensing element pattern 30 are overlapped, the directivity of the light condensing element pattern 30 and the pixel pattern 20 coincides, as shown in FIG. In addition, it is possible to make the transparent material 10 appear in a static state with little fluctuation without being restricted by the position where the enlarged virtual image Z of each pixel 21 is viewed.

  Next, a method for authenticating the product G using the product authentication display 1 will be described.

  In a printing factory or the like, the light condensing element pattern 30 is formed by printing the light condensing element 31 with a transparent ink on the surface of the transparent material 10. The transparent material 10 provided with the light condensing element pattern 30 is distributed in advance to a store such as a wholesale store or a retail store of the product G.

  On the other hand, the pixel pattern 20 is formed by printing the pixel 21 with ink at a predetermined location such as a corner of the surface of the product G in a manufacturing factory of the product G. The product G on which the pixel pattern 20 is printed is shipped from a manufacturing factory or the like to a store or the like.

  Next, in a store or the like to which the product G has been delivered, the operator brings the front surface of the product G into contact with the back surface of the transparent material 10 (the surface on which the light condensing element pattern 30 is not formed) as shown in FIG. In this manner, the transparent material 10 is placed on the pixel pattern 20 of the product G. At this time, the operator adjusts the position of the transparent material 10 in the plane direction with respect to the product G while moving the transparent material 10 little by little in the plane direction, whereby the frame line 32 of the transparent material 10 and the frame line 22 of the product G are changed. Match to match.

  As a result, the light condensing element pattern 30 surrounded by the frame line 32 is appropriately placed on the pixel pattern 20 surrounded by the frame line 22 via the transparent material 10, and the pixel pattern 20 and Since the directionality of the light condensing element pattern 30 is the same, the enlarged virtual image Z of each pixel 21 appears above the transparent material 10 in a static state with little fluctuations without being limited by the position where the pixel 21 is viewed. .

  Next, the operator visually recognizes the inside of the frame 32 of the transparent material 10 from above the transparent material 10 while maintaining the state where the transparent material 10 is placed on the pixel pattern 20. The enlarged virtual image Z of each pixel 21 is observed.

  At this time, for example, as shown in FIG. 5, when a predetermined enlarged virtual image Z appears in a clear state above the transparent material 10, the operator assumes that an appropriate pixel pattern 20 is formed on the product G. It can authenticate that goods G are genuine. On the other hand, for example, as shown in FIG. 6, when the predetermined enlarged virtual image Z does not appear above the transparent material 10, the operator assumes that the proper pixel pattern 20 is not formed on the product G and the product G If it is not genuine, it can be authenticated. Alternatively, when an unclear enlarged virtual image Z having a blurred outline appears above the transparent material 10 or when an enlarged virtual image different from the predetermined enlarged virtual image Z appears, the operator can If the proper pixel pattern 20 is not formed, it can be authenticated that the product G is not a genuine product.

  According to this, since the authentication work is completed simply by confirming the presence or absence of the enlarged virtual image Z appearing above the transparent material 10 or the sharpness, it is possible to authenticate whether or not the product is genuine. it can. Moreover, since the pixel pattern 20 can be provided by printing, the manufacturing cost of the product G to which the authentication information is given by the pixel pattern 20 can be reduced. Furthermore, while having some technical difficulty in imitation of the product authentication display 1, the technology for imitation of the product authentication display 1 by complicating the pixel pattern 20 and / or the light condensing element pattern 30. Difficulty can be increased.

  In the present embodiment, the pixel pattern 20 and the light condensing element pattern 30 are formed by printing, but may be formed by other methods.

  In addition, although the frame lines 22 and 32 having the same shape are provided on the periphery of the pixel pattern 20 and the periphery of the light condensing element pattern 30, respectively, either one or both may not be provided.

  Although the pixel pattern 20 is formed on the product G, the pixel pattern 20 may be formed on an accessory such as a packaging box, a price tag, or a label of the product G.

  Moreover, although the arrangement pitch p of the pixels 21 is larger than the arrangement pitch q of the light condensing elements 31, it may be smaller. In this way, when the arrangement pitch p of the pixels 31 is smaller than the arrangement pitch q of the light condensing elements 31, there is no restriction on the position where the enlarged virtual image of each pixel 21 is viewed, and in a static state with little fluctuation. It can appear below the transparent material 10.

  Further, although the arrangement pitch p of the pixels 21 is constant, the arrangement pitch p of the pixels 21 may be changed. According to this, the enlarged virtual image of each pixel 21 appears above or below the transparent material while gradually changing the height or depth, and constitutes a three-dimensional enlarged virtual image group having a gentle curved surface as a whole. be able to. For this reason, since the enlarged virtual image of each pixel 21 can function as more advanced authentication information, it is possible to increase technical difficulty in imitation of the product authentication display body 1.

Moreover, although the arrangement pitch q of the light condensing elements 31 is constant, the arrangement pitch q of the light condensing elements 31 may be changed. According to this, the enlarged virtual image of each pixel 21 appears above or below the transparent material while gradually changing the height or depth, and constitutes a three-dimensional enlarged virtual image group having a gentle curved surface as a whole. be able to. For this reason, since the enlarged virtual image of each pixel 21 can function as more advanced authentication information, it is possible to increase technical difficulty in imitation of the product authentication display body 1. In addition, it is not necessary to set a change in the arrangement pitch of the pixels 21 and it becomes easy to set a complicated pixel shape, so that variations in the design of the enlarged virtual image of the pixels 21 can be easily increased.

  The authentication unit 51 receives image data of the enlarged virtual image Z from the transmission / reception unit 54 according to a command from the control unit 55 and receives image data of an appropriate enlarged virtual image stored in advance in the storage unit 52 from the storage unit 52. . Then, the authentication unit 51 collates the image data of the enlarged virtual image Z received from the receiving unit 54 with the image data of the appropriate enlarged virtual image received from the storage unit 52, and when the image data of both enlarged virtual images match. The authentication unit 51 authenticates the product G as a genuine product. On the other hand, when the image data of both enlarged virtual images do not match, the authentication unit 51 authenticates the product G as not genuine (non-genuine product). Whether or not the image data of the both enlarged virtual images coincides is determined, for example, based on one or more elements of the shape, size, sharpness, or hue of the image data of both enlarged virtual images.

  The storage unit 52 stores image data of an appropriate magnified virtual image for the genuine product in advance, and transmits the image data of the magnified virtual image to the authentication unit 51 according to a command from the control unit 55.

The basic operation of the entire computer 50 is controlled by executing the OS stored in the ROM. Further, the control unit 55 transmits the image data of the enlarged virtual image Z received from the imaging unit 40 by the transmission / reception unit 54 to the authentication unit 51, and the appropriate enlarged virtual image image data stored in advance in the storage unit 52. It transmits to the authentication unit 51. In addition, the control unit 55 transmits the authentication result by the authentication unit 51 to the output unit 53.

  First, at the wholesale or retail store where the product G is delivered, the operator, as shown in FIG. 4, displays the surface of the product G and the back surface of the transparent material 10 (the surface on which the light condensing element pattern 30 is not formed). The transparent material 10 is placed on the pixel pattern 20 of the product G in a manner to be brought into contact. At this time, the operator adjusts the position of the transparent material 10 in the plane direction with respect to the product G while moving the transparent material 10 little by little in the plane direction, whereby the frame line 32 of the transparent material 10 and the frame line 22 of the product G are changed. Match to match.

  As a result, the light condensing element pattern 30 surrounded by the frame line 32 is appropriately placed on the pixel pattern 20 surrounded by the frame line 22 via the transparent material 10, and the pixel pattern 20 and Since the directivity of the light condensing element pattern 30 matches, the enlarged virtual image Z composed of the enlarged virtual image of each pixel 21 appears above the transparent material 10 in a static state with little fluctuation without being restricted by the viewing position. Will be put out.

  Then, the operator places the imaging unit 40 above the transparent material 10 while maintaining the state where the transparent material 10 is placed on the pixel pattern 20, and starts imaging the enlarged virtual image Z of each pixel 21.

  Then, the imaging unit 40 transmits the captured image data of the enlarged virtual image Z to the computer 50. In the computer 50, the reception unit 54 receives the image data of the enlarged virtual image Z transmitted from the imaging unit 40 (S2).

  Then, the authentication unit 51 receives the image data of the enlarged virtual image Z from the transmission / reception unit 54 according to the command of the control unit 55, and transmits the appropriate enlarged virtual image image data previously stored in the storage unit 52 via the control unit 55. Are received, and the image data of the enlarged virtual images of both of them are collated. At this time, when the image data of both enlarged virtual images match, the authentication unit 51 authenticates the product G as a genuine product and transmits a positive authentication result to the output unit 53. On the other hand, when the image data of the both enlarged virtual images do not match, the authentication unit 51 authenticates the product G as not authentic and transmits a negative authentication result to the output unit 53 (S3). .

  Finally, the output unit 53 outputs the authentication result by the authentication unit 51 (S4). Note that the authentication result output from the output unit 53 may be a voice, or may be an image or a character.

  Therefore, the operator can authenticate whether or not the product G is a genuine product based on the authentication result output from the output unit 53.

According to this, the authentication work of the enlarged virtual image of the pixel 21 can be automated, and authentication errors can be reduced. Even if the enlarged virtual image of the pixel 21 is complicated by complicating the shape and pattern of the pixel 21, the enlarged virtual image of the pixel 21 can be sufficiently authenticated by the authentication unit 51 in the computer 50. Authentication information can be given.

  First, at the wholesale or retail store where the product G is delivered, the operator, as shown in FIG. 4, displays the surface of the product G and the back surface of the transparent material 10 (the surface on which the light condensing element pattern 30 is not formed). The transparent material 10 is placed on the pixel pattern 20 of the product G in a manner to be brought into contact. At this time, the operator adjusts the position of the transparent material 10 in the plane direction with respect to the product G while moving the transparent material 10 little by little in the plane direction, whereby the frame line 32 of the transparent material 10 and the frame line 22 of the product G are changed. Match to match.

  As a result, the light condensing element pattern 30 surrounded by the frame line 32 is appropriately placed on the pixel pattern 20 surrounded by the frame line 22 via the transparent material 10, and the pixel pattern 20 and Since the directivity of the light condensing element pattern 30 matches, the enlarged virtual image Z composed of the enlarged virtual image of each pixel 21 appears above the transparent material 10 in a static state with little fluctuation without being restricted by the viewing position. Will be put out.

  Then, the operator places the imaging unit 61 of the portable information terminal 60 above the transparent material 10 while maintaining the state where the transparent material 10 is placed on the pixel pattern 20, and the enlarged virtual image Z of each pixel 21. Start imaging.

  Next, as shown in the flowchart of FIG. 11, in the product authentication system 101, the imaging unit 61 captures an enlarged virtual image Z of each pixel 21 from above the transparent material 10 (S1).

  Then, the imaging unit 61 transmits the image data of the enlarged virtual image Z to the transmission / reception unit 64 according to a command from the control unit 65. The transmission / reception unit 64 receives the image data of the enlarged virtual image Z transmitted from the imaging unit 40 and transmits it to the transmission / reception unit 74 of the server 70 (S2).

  Then, in the server 70, the transmission / reception unit 74 receives the image data of the enlarged virtual image Z transmitted from the transmission / reception unit 64 of the portable information terminal 60 (S3).

  Then, the authentication unit 71 receives the image data of the enlarged virtual image Z from the transmission / reception unit 74 according to the instruction of the control unit 75 and also receives the image data of the appropriate enlarged virtual image stored in advance in the storage unit 72 from the storage unit 72. Then, the image data of the enlarged virtual images of both are collated. At this time, when the image data of both enlarged virtual images match, the authentication unit 71 authenticates the product G as a genuine product and transmits a positive authentication result to the transmission / reception unit 74. On the other hand, when the image data of both enlarged virtual images do not match, the authentication unit 71 authenticates the product G as not authentic and transmits a negative authentication result to the transmission / reception unit 74 (S4). .

  And the transmission / reception part 74 transmits the authentication result by the authentication part 71 to the transmission / reception part 64 of the portable information terminal 60 (S5).

  And in the portable information terminal 60, the transmission / reception part 64 receives the authentication result by the authentication part 71 transmitted from the transmission / reception part 74 of the server 70, and transmits to the output part 63 (S6).

  Finally, the output unit 63 outputs an authentication result by the authentication unit 71 according to a command from the control unit 65 (S7). Note that the authentication result output from the output unit 63 may be a voice, or may be an image or a character.

  Therefore, the operator can authenticate whether or not the product G is a genuine product based on the authentication result output from the output unit 63.

  According to this, the authentication work of the enlarged virtual image of the pixel 21 can be automated, and authentication errors can be reduced. Further, even if the enlarged virtual image of the pixel 21 is complicated by complicating the shape and pattern of the pixel 21, the authentication unit 71 in the server 70 can sufficiently authenticate the enlarged virtual image of the pixel 21. Authentication information can be given.

  In addition, the operator can easily authenticate the product by connecting to the server computer via the network from his / her portable information terminal, and the cost can be kept low because there is no need to provide a dedicated device. Further, since the system can be updated by updating the authentication means in the server computer, the product authentication system can be easily maintained.

  The pixel pattern 20 may be formed of a fluorescent paint that emits light when irradiated with UV light. According to this, since the pixel pattern 20 emits light by irradiating the product authentication display body 1 with UV light, in addition to the authentication information based on the enlarged virtual image, the presence / absence of light emission and the luminous intensity of the pixel pattern 20 are used as authentication information. Can function.

  The pixel pattern 20 may be provided with a phosphorescent layer that absorbs ultraviolet rays such as a fluorescent lamp and sunlight and emits light in a dark place in the background. According to this, since the background of the pixel pattern 20 emits light by disposing the product authentication display body 1 in a dark place, in addition to the authentication function based on the enlarged virtual image, whether or not the background of the pixel pattern 20 emits light and the luminous intensity. Can function as authentication information.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of embodiment shown in figure. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.
