Description

Technology Field

[0001] The present invention relates to a method for manufacturing a uniform having an anti-counterfeiting function and a method for determining the authenticity thereof. More specifically, it relates to a method for manufacturing a uniform having an anti-counterfeiting function and a method for determining the authenticity thereof, which makes the production of counterfeit uniforms virtually impossible and fundamentally blocks illegal distribution through a halftone code embedded in the pattern of the uniform itself. Background Technology

[0003] The issue of counterfeiting clothing and textile products has been a long-standing global concern and is emerging as a serious problem, particularly for special-purpose clothing such as military, police, and corporate uniforms. Since these uniforms are not merely simple garments but products that perform critical functions such as security, identification, and brand identity, the circulation of counterfeit goods in the market can lead to social, economic, and security problems.

[0004] In recent years, genuine manufacturers and consumers have been suffering damages as counterfeit uniforms have been distributed in large quantities through online shopping malls and unofficial distribution channels. Particularly in regions where the distribution of counterfeit products is active, uniforms with designs nearly identical to genuine ones are frequently produced with low quality and sold illegally.

[0005] Uniforms are not merely clothing but play a crucial role in distinguishing members of specific professions or organizations. In particular, if clothing directly related to public safety, such as military or police uniforms, is counterfeited, it can pose a serious security threat to the nation and society.

[0006] For example, if uniforms worn by police or soldiers are counterfeited and used illegally, the risk of impersonation crimes increases. In fact, there have been reports in some countries of criminal organizations committing robberies or fraud while wearing counterfeit police uniforms. Furthermore, if counterfeit military uniforms are used by illegal armed groups or terrorist organizations, there is also a possibility that they could pose a direct threat to national security.

[0007] Corporate uniforms are also linked to security. For example, if uniforms worn by security personnel at large logistics companies or financial institutions are counterfeited, they can be exploited for burglaries and criminal activities. There have been reports of criminals wearing forged delivery driver uniforms to deceive consumers and gain access to homes or offices, posing a significant threat not only to corporate security but also to the safety of general consumers.

[0008] Companies provide official uniforms to employees to emphasize brand identity, enhance credibility, and maintain a consistent image. However, if counterfeit uniforms are distributed, the corporate image can be severely damaged.

[0009] Counterfeit uniforms are generally produced using low-quality fabric and shoddy sewing techniques, so the overall quality of service may deteriorate when employees wear them. For example, if a customer mistakes an employee wearing a counterfeit uniform for an official staff member, they may experience poor service or unfriendly treatment. This becomes a significant factor that can undermine a company's credibility among customers.

[0010] Furthermore, some counterfeit product vendors illegally use corporate logos and designs to sell products as if they were official goods. If such counterfeit uniforms are distributed in the market, it not only damages the company's brand image but also confuses customers, resulting in a decline in brand value.

[0011] As counterfeit uniforms increase, genuine manufacturers are suffering economic losses such as reduced sales and declining revenue.

[0012] Since uniforms are typically custom-made for specific companies, institutions, or organizations, genuine manufacturers produce their products using high-quality fabrics and precise sewing techniques. However, counterfeit products use cheaper fabrics and low-quality manufacturing methods to cut costs, resulting in them being distributed in the market at much lower prices. Consequently, some consumers end up purchasing counterfeit uniforms based solely on the price difference.

[0013] In particular, with the advancement of digital printing technology, it has become easier to replicate even unique patterns, leading to increasingly sophisticated counterfeit products. This results in the design and technology developed by genuine manufacturers being copied and sold verbatim, which can also lead to issues regarding the infringement of corporate intellectual property rights.

[0014] Although various technologies have been applied to prevent forgery issues, existing methods have several limitations.

[0015] First, methods such as attaching RFID tags, holographic labels, and barcodes are used to verify authenticity. However, these physical security devices can easily fall off or be damaged, and there is a growing number of cases where counterfeiters manufacture and duplicate similar tags. For instance, holographic labels are often difficult to verify with the naked eye, leading to an increase in professional counterfeiters producing and selling similar holograms.

[0016] In addition, some companies provide unique product serial numbers or QR codes to verify authenticity. However, since QR codes and barcodes are easy to digitally duplicate, a problem is arising where the same codes are applied to counterfeit products through online manipulation. The problem to be solved

[0018] The present invention aims to provide a method for manufacturing a uniform having an anti-counterfeiting function that makes the counterfeit production of the uniform virtually impossible and fundamentally blocks illegal distribution through a halftone code embedded in the pattern of the uniform itself, and a method for determining the authenticity thereof.

[0020] The objects of the present invention are not limited to those mentioned above, and other unmentioned objects and advantages of the present invention may be understood from the following description and will be more clearly understood by the embodiments of the present invention. Furthermore, it will be readily apparent that the objects and advantages of the present invention can be realized by the means and combinations thereof set forth in the claims. means of solving the problem

[0022] A method for manufacturing a uniform having an anti-counterfeiting function, executed in a uniform manufacturing device for achieving such an purpose, comprises the steps of generating a basic pattern image for the uniform, generating a point cloud pattern image linking authenticity information of the uniform, generating a final pattern image using the basic pattern image and the point cloud pattern image, and manufacturing the uniform by printing the final pattern image onto a fiber.

[0023] In one embodiment, the step of generating a final pattern image using the basic pattern image and the point cloud pattern image includes: placing the point cloud pattern image on top of the basic pattern image to arrange it in a layer structure; and adjusting the color step difference between the basic pattern image and the point cloud pattern image to generate the final pattern image.

[0024] In one embodiment, the step of generating a final pattern image by adjusting the color difference between the basic pattern image and the point cloud pattern image includes the step of generating a final pattern image by increasing or decreasing the pixels of the point cloud pattern image by a certain value based on the pixel color value of the basic pattern image.

[0025] In one embodiment, the step of generating a point cloud pattern image connecting the authenticity information of the uniform comprises: generating a data code by representing the data connecting the authenticity information of the uniform in binary bits; generating a verification code for the data code and generating a data code with the verification code inserted using the verification code for the data code; representing the data code with the verification code inserted on a point cloud representation area; and generating a point cloud pattern image data that has been fast-fourier transformed by performing a fast-fourier transform on a pre-generated position determination pattern indicating the location of the point cloud representation area and the point cloud representation area.

[0026] In addition, a method for determining the authenticity of a uniform executed in a uniform authenticity determination device for achieving this purpose includes the steps of: generating scan image data by scanning a uniform created by printing a final pattern image, generated based on a basic pattern image and a point cloud pattern image, onto a fiber; generating scan image data that has undergone Fast Fourier Inverse Transform by performing Fast Fourier Inverse Transform on the scan image data; generating corrected scan image data by correcting the position of a point cloud based on a position determination pattern on the scan image data that has undergone Fast Fourier Inverse Transform; and analyzing the corrected scan image data to extract a data code with a verification code inserted therein and determining the authenticity of the uniform based on the authenticity information of the uniform connected to the data code.

[0027] In one embodiment, the final pattern image can be generated by placing the point cloud pattern image on top of the basic pattern image to form a layer structure, and adjusting the color step difference between the basic pattern image and the point cloud pattern image.

[0028] In one embodiment, the final pattern image can be generated by increasing or decreasing the pixels of the point cloud pattern image by a certain amount based on the pixel color values ​​of the basic pattern image. Effects of the invention

[0030] According to the present invention as described above, there is an advantage in that the counterfeit production of the uniform is virtually impossible and illegal distribution can be fundamentally blocked through the halftone code embedded in the pattern of the uniform itself.

[0033] The aforementioned objectives, signatures, and advantages are described in detail below with reference to the attached drawings, thereby enabling those skilled in the art to easily implement the technical concept of the present invention. In describing the present invention, detailed descriptions of known technologies related to the present invention are omitted if it is determined that such descriptions would unnecessarily obscure the essence of the invention. Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings. In the drawings, the same reference numerals are used to indicate the same or similar components.

[0035] As used herein, the term “uniform” refers to clothing worn by specific organizations, professions, sports teams, etc., to maintain a unified appearance. It includes various types depending on the use and purpose, and is clothing used by users belonging to the military, police, medical institutions, firefighters, schools, sports groups, etc. For example, uniforms may include, but are not limited to, military uniforms, school uniforms, hospital uniforms, firefighter fireproof suits, police uniforms, etc.

[0037] FIG. 1 is a network configuration diagram for explaining a uniform authenticity determination system according to one embodiment of the present invention.

[0038] Referring to FIG. 1, the uniform authenticity determination system includes a uniform manufacturing device (100) and a uniform authenticity determination device (200).

[0039] A uniform manufacturing device (100) is a device that manufactures a uniform (300) by generating a final pattern image using a point cloud pattern image that connects a basic pattern image for the uniform (300) and authenticity information of the uniform (300), and then printing the final pattern image onto a fiber.

[0040] First, the uniform manufacturing device (100) generates a data code by representing data connecting the authenticity information of the uniform (300) as binary bits, generates a verification code for the data code, and generates a data code with the verification code inserted using the verification code for the data code.

[0041] After that, the uniform manufacturing device (100) generates a point cloud pattern by displaying a data code with a verification code inserted on a point cloud representation area. At this time, the point cloud representation area may be formed with a width and height between, for example, 32 bits and 35 bits. However, this can be modified and applied by a person skilled in the art to suit the purpose or environment of implementation.

[0042] In one embodiment, the uniform manufacturing device (100) generates a point cloud pattern by representing 0 or 1 on a point cloud representation area according to the binary bits of the data code into which the verification code is inserted.

[0043] The uniform manufacturing device (100) generates a fast Fourier transform point cloud pattern image by performing a fast Fourier transform on a point cloud representation area and a position determination pattern. At this time, the position determination pattern is used to determine the starting position of the point cloud on the point cloud pattern image when the uniform (300) is scanned and the point cloud pattern is decoded after the point cloud pattern image is printed on the uniform (300).

[0044] After that, the uniform manufacturing device (100) generates a final point cloud pattern image using a plurality of point cloud pattern images. Each point cloud pattern image constituting the point cloud pattern is fast Fourier transformed together with a position determination pattern.

[0045] The uniform manufacturing device (100) generates a final pattern image using a basic pattern image and a point cloud pattern image.

[0046] In one embodiment, the uniform manufacturing device (100) includes the step of placing the point cloud pattern image on top of a basic pattern image to form a layer structure, and adjusting the color step difference between the basic pattern image and the point cloud pattern image to generate a final pattern image.

[0047] In the above embodiment, the uniform manufacturing device (100) can generate a final pattern image by increasing or decreasing the pixels of a point cloud pattern image by a certain amount based on the pixel color value of a basic pattern image.

[0048] For example, the uniform manufacturing device (100) can make the point cloud pattern slightly darker than the existing pattern by applying -10 to each value when the basic pattern pixel value is (R, G, B) = (120, 130, 140) and the point cloud pattern is negative (i.e., 0).

[0049] As another example, the uniform manufacturing device (100) can make the point cloud pattern appear slightly brighter than the original pattern by applying +10 to each value when the basic pattern pixel value is (R, G, B) = (120, 130, 140) and the point cloud pattern is positive (i.e., 1), thereby adjusting it to (130, 140, 150).

[0050] To this end, the uniform manufacturing device (100) can convert the RGB values ​​of the basic pattern image and the point cloud pattern image into the Lab color space and then calculate the color difference to check whether it is located within a specific range.

[0051] In one embodiment, the uniform manufacturing device (100) can calculate the color difference after converting the RGB values ​​of the basic pattern image and the point cloud pattern image into the Lab color space as in [Equation 1].

[0052] In this context, the Lab color space is a color representation method based on how the human eye perceives color. The Lab color space consists of three axes: L, a, and b, where L represents brightness, a represents the green-red axis, and b represents the blue-yellow axis.

[0054] [Mathematical Formula 1]

[0055]

[0057] △E: Color difference,

[0058] L: Brightness,

[0059] a: Red-green value,

[0061] As described above, the reason for converting the RGB values ​​of the basic pattern image and the point cloud pattern image to the Lab color space is that in RGB, (255, 0, 0) and (254, 0, 0) appear to be almost the same red to the naked eye, but in Lab, the color difference (ΔE) is slightly different and detectable.

[0062] The larger the color difference value mentioned above, the more the color is perceived differently. Color difference (ΔE) can be set to 76, 94, or 2000, but general smartphone cameras have high recognition accuracy based on a ΔE of 2000. Therefore, when ΔE is 5 or less, the difference is barely detectable by both the naked eye and the camera; when ΔE is 10 to 15, it is invisible to the naked eye but detectable by the camera; and when ΔE is 20, it can be distinguished even with the naked eye.

[0063] [Table 1] below explains the process for setting the optimal color step difference.

[0065] [Table 1]

[0066]

[0068] For example, if a specific pixel of the basic pattern image is Lab(70, 0, 0), the corresponding pixel of the point cloud pattern image is adjusted to Lab(75, 5, -5), there is no significant difference to the naked eye, but the uniform authenticity determination device (200) can distinguish it by setting the color difference (ΔE) value to 12.

[0069] As described above, by utilizing the Lab color space in this way, color differences that are invisible to the naked eye but detectable by a camera can be accurately controlled.

[0070] The uniform manufacturing device (100) manufactures the uniform (300) by printing a final pattern image onto a fiber.

[0071] A point cloud pattern may be printed on the uniform (300) produced as described above, but it may be visually indistinguishable. In this case, each of the intaglio and relief may indicate 0 or 1. That is, it may be predefined that the relief indicates 0 and the intaglio indicates 1, or it may be predefined that the relief indicates 1 and the intaglio indicates 0.

[0072] The above point cloud pattern recognizes a code value that is reflected and displayed through a flash or camera light provided to the uniform authenticity determination device (200), and then links the authenticity information of the uniform (300) corresponding to the code value. The code value can be various information utilizing the characteristics of light.

[0073] The uniform authenticity determination device (200) generates scan image data by scanning a uniform created by printing a final pattern image, generated based on a basic pattern image and a point cloud pattern image, onto a fabric (step S310).

[0074] At this time, the uniform (300) has data coded according to image data generated by Fast Fourier Transform, including a point cloud representation area and a pre-generated position determination pattern indicating the location of the point cloud representation area.

[0075] It is preferable for the uniform authenticity determination device (200) to operate the flash when taking a photograph, that is, when photographing the uniform (300). Of course, if a separate flash device is used or if there is light in the surroundings, the light can be utilized, so in this case, the flash may not be used. However, it is preferable for the flash to be kept on at all times.

[0076] The uniform authenticity determination device (200) generates scan image data that has been fast-fourier transformed by performing a fast-fourier transform on the scan image data.

[0077] The uniform authenticity determination device (200) generates corrected scan image data by correcting the position of a point group based on a position determination pattern on the scan image data that has been fast Fourier transformed.

[0078] That is, even if the user does not photograph the uniform from the front, distortion may occur in the scan image data if it is photographed from any direction, so scan image data with the position of the point cloud corrected based on the position determination pattern on the scan image data that has been fast Fourier transformed is generated.

[0079] The uniform authenticity determination device (200) analyzes the corrected scan image data and extracts a data code with a verification code inserted.

[0080] The uniform authenticity determination device (200) analyzes corrected scan image data to extract a data code with a verification code inserted, and determines the authenticity of the uniform based on the authenticity information of the uniform connected to the data code.

[0082] FIG. 2 is a flowchart illustrating an embodiment of a method for manufacturing a uniform having an anti-counterfeiting function according to the present invention.

[0083] Referring to FIG. 2, the uniform manufacturing device (100) generates a basic pattern image for the uniform (step S210).

[0084] The uniform manufacturing device (100) generates a point cloud pattern image connecting the authenticity information of the uniform (step S220).

[0085] In one embodiment for step S220, the uniform manufacturing device (100) generates a data code by representing data connecting the authenticity information of the uniform as binary bits, generates a verification code for the data code, and generates a data code with the verification code inserted using the verification code for the data code.

[0086] After that, the uniform manufacturing device (100) generates a point cloud pattern by displaying a data code with a verification code inserted on a point cloud representation area. At this time, the point cloud representation area may be formed with a width and height between, for example, 32 bits and 35 bits. However, this can be modified and applied by a person skilled in the art to suit the purpose or environment of implementation.

[0087] In one embodiment, the uniform manufacturing device (100) generates a point cloud pattern by representing 0 or 1 on a point cloud representation area according to the binary bits of the data code into which the verification code is inserted.

[0088] The uniform manufacturing device (100) generates a fast Fourier transform point cloud pattern image by performing a fast Fourier transform on a point cloud representation area and a position determination pattern. At this time, the position determination pattern is used to determine the starting position of the point cloud on the point cloud pattern image when the uniform (300) is scanned and the point cloud pattern is decoded after the point cloud pattern image is printed on the uniform (300).

[0089] After that, the uniform manufacturing device (100) generates a final point cloud pattern image using a plurality of point cloud pattern images. Each point cloud pattern image constituting the point cloud pattern is fast Fourier transformed together with a position determination pattern.

[0090] The uniform manufacturing device (100) generates a final pattern image using a basic pattern image and a point cloud pattern image (step S230).

[0091] In one embodiment for step S230, the uniform manufacturing device (100) includes the step of placing the point cloud pattern image on top of a basic pattern image to form a layer structure, and adjusting the color step difference between the basic pattern image and the point cloud pattern image to generate a final pattern image.

[0092] In the above embodiment, the uniform manufacturing device (100) can generate a final pattern image by increasing or decreasing the pixels of a point cloud pattern image by a certain amount based on the pixel color value of a basic pattern image.

[0093] For example, the uniform manufacturing device (100) can make the point cloud pattern slightly darker than the existing pattern by applying -10 to each value when the basic pattern pixel value is (R, G, B) = (120, 130, 140) and the point cloud pattern is negative (i.e., 0).

[0094] As another example, the uniform manufacturing device (100) can make the point cloud pattern appear slightly brighter than the original pattern by applying +10 to each value when the basic pattern pixel value is (R, G, B) = (120, 130, 140) and the point cloud pattern is positive (i.e., 1), thereby adjusting it to (130, 140, 150).

[0095] The uniform manufacturing device (100) manufactures the uniform by printing a final pattern image onto a fabric (step S240).

[0096] A point cloud pattern may be printed on the uniform produced as described above, but it may be visually indistinguishable. In this case, the intaglio and relief may each indicate 0 or 1. That is, it may be predefined that the relief indicates 0 and the intaglio indicates 1, or that the relief indicates 1 and the intaglio indicates 0.

[0097] The above point cloud pattern recognizes a code value that is reflected and displayed through a flash or camera light provided to the uniform authenticity determination device (200), and then links the authenticity information of the uniform corresponding to the code value. The code value can be various information utilizing the characteristics of light.

[0099] FIG. 3 is a flowchart illustrating an embodiment of a method for determining the authenticity of a uniform according to the present invention.

[0100] Referring to FIG. 3, the uniform authenticity determination device (200) generates scan image data by scanning a uniform created by printing a final pattern image, generated based on a basic pattern image and a point cloud pattern image, onto a fiber (step S310).

[0101] At this time, the uniform (300) has data coded according to image data generated by Fast Fourier Transform, including a point cloud representation area and a pre-generated position determination pattern indicating the location of the point cloud representation area.

[0102] It is preferable for the uniform authenticity determination device (200) to operate the flash when taking a photograph, that is, when photographing the object (300). Of course, if a separate flash device is used or if there is light in the surroundings, that light can be used, then the flash may not be used in this case. However, it is preferable for the flash to be kept on at all times.

[0103] The uniform authenticity determination device (200) generates scan image data by performing a Fast Fourier Transform on the scan image data (step S320).

[0104] The uniform authenticity determination device (200) generates corrected scan image data by correcting the position of a point group based on a position determination pattern on the scan image data that has been fast Fourier transformed (step S330).

[0105] That is, even if the user does not photograph the uniform from the front, distortion may occur in the scan image data if it is photographed from any direction, so scan image data with the position of the point cloud corrected based on the position determination pattern on the scan image data that has been fast Fourier transformed is generated.

[0106] The uniform authenticity determination device (200) analyzes the corrected scan image data and extracts a data code with a verification code inserted (step S340).

[0107] The uniform authenticity determination device (200) analyzes the corrected scan image data to extract a data code with a verification code inserted and determines the authenticity of the uniform based on the authenticity information of the uniform connected to the data code (step S350).

[0109] FIGS. 4 to 6 are illustrative diagrams for explaining a uniform manufacturing process according to the present invention.

[0110] Referring to FIGS. 4 to 6, the uniform manufacturing device (100) generates a data code by representing data connecting the authenticity information of the uniform (300) as binary bits, generates a verification code for the data code, and generates a data code with the verification code inserted using the verification code for the data code.

[0111] After that, the uniform manufacturing device (100) generates a point cloud pattern by displaying a data code with a verification code inserted on a point cloud representation area. At this time, the point cloud representation area may be formed with a width and height between, for example, 32 bits and 35 bits. However, this can be modified and applied by a person skilled in the art to suit the purpose or environment of implementation.

[0112] In one embodiment, the uniform manufacturing device (100) generates a point cloud pattern by representing 0 or 1 on a point cloud representation area according to the binary bits of the data code into which the verification code is inserted.

[0113] The uniform manufacturing device (100) performs a Fast Fourier Transform on the point cloud representation area and the position determination pattern to generate the Fast Fourier Transformed point cloud pattern image of FIG. 5. At this time, the position determination pattern is used to determine the starting position of the point cloud on the point cloud pattern image when the uniform (300) is scanned and the point cloud pattern is decoded after the point cloud pattern image is printed on the uniform (300).

[0114] After that, the uniform manufacturing device (100) generates a final point cloud pattern image using a plurality of point cloud pattern images of FIG. 5. Each point cloud pattern image constituting the point cloud pattern is fast Fourier transformed together with a position determination pattern.

[0115] Accordingly, the uniform manufacturing device (100) generates the final pattern image of Fig. 6 using the basic pattern image of Fig. 4 and the point cloud pattern image of Fig. 5.

[0116] In one embodiment, the uniform manufacturing device (100) includes the step of placing a point cloud pattern image on top of a basic pattern image to arrange it in a layer structure, and adjusting the color step difference between the basic pattern image and the point cloud pattern image to generate a final pattern image.

[0117] In the above embodiment, the uniform manufacturing device (100) can generate a final pattern image by increasing or decreasing the pixels of a point cloud pattern image by a certain amount based on the pixel color value of a basic pattern image.

[0118] For example, the uniform manufacturing device (100) can make the point cloud pattern slightly darker than the existing pattern by applying -10 to each value when the basic pattern pixel value is (R, G, B) = (120, 130, 140) and the point cloud pattern is negative (i.e., 0).

[0119] As another example, the uniform manufacturing device (100) can make the point cloud pattern appear slightly brighter than the original pattern by applying +10 to each value when the basic pattern pixel value is (R, G, B) = (120, 130, 140) and the point cloud pattern is positive (i.e., 1), thereby adjusting it to (130, 140, 150).

[0120] The uniform manufacturing device (100) manufactures the uniform (300) by printing a final pattern image onto a fiber.

[0121] A point cloud pattern may be printed on the uniform (300) produced as described above, but it may be visually indistinguishable. In this case, each of the intaglio and relief may indicate 0 or 1. That is, it may be predefined that the relief indicates 0 and the intaglio indicates 1, or it may be predefined that the relief indicates 1 and the intaglio indicates 0.

[0122] The above point cloud pattern recognizes a code value that is reflected and displayed through a flash or camera light provided to the uniform authenticity determination device (200), and then links the authenticity information of the uniform (300) corresponding to the code value. The code value can be various information utilizing the characteristics of light.
