[0001] This invention relates to the field of anti-counterfeiting technology in printing, specifically to a method, storage medium, and device for achieving anti-counterfeiting of cigarette product packaging. Background Technology

[0002] Anti-counterfeiting packaging is one of the most effective measures to prevent counterfeit and shoddy goods. Therefore, cigarette packaging uses a large number of anti-counterfeiting technologies in the production process to combat the counterfeit cigarette market and protect the legitimate rights and interests of consumers.

[0003] Currently, relatively mature anti-counterfeiting technologies for cigarette packaging include holographic paper anti-counterfeiting technology, optically variable ink anti-counterfeiting technology, microprinting anti-counterfeiting technology, DNA ink anti-counterfeiting technology, and fluorescent ink anti-counterfeiting technology. Existing anti-counterfeiting technologies are basically based on anti-counterfeiting inks. However, the anti-counterfeiting inks currently used are generally expensive, and these technologies have been prevalent in the packaging market for decades. Some counterfeiters can now replicate packaging with similar effects, and ordinary consumers find it difficult to distinguish them with the naked eye. Therefore, there is an urgent need for an effective anti-counterfeiting method for cigarette packaging. Summary of the Invention

[0015] Fluorescent reverse varnish is transferred to the surface of the cigarette box through an engraved printing plate, resulting in a logo pattern on the cigarette box surface. The fluorescent reverse varnish in the logo pattern freely and randomly shrinks on the surface of the cigarette box.

[0016] The fluorescent reverse varnish on the surface of the cigarette box is dried using the gravure printing machine's drying system.

[0017] Based on the above technical solution, the steps of collecting random fluorescent images generated by the shrinkage of fluorescent reverse varnish at the marking pattern on the surface of the cigarette box and converting the random fluorescent images into binary data include:

[0018] By illuminating the markings on the surface of the cigarette pack with an ultraviolet light source, a CCD camera is used to capture random fluorescent images that appear due to the ultraviolet light irradiation.

[0019] The acquired random fluorescence images were converted into black and white images using MATLAB software. The binary data corresponding to the random fluorescence images were obtained by representing each pixel of the black and white images in binary form.

[0020] Based on the above technical solution, the step of encrypting the plaintext data corresponding to the current cigarette box using the converted binary data to achieve anti-counterfeiting processing of the current cigarette box includes the following steps:

[0021] Retrieve the plaintext data corresponding to the current cigarette pack, and each cigarette pack corresponds to a unique plaintext data;

[0022] The binary data obtained from the conversion of the current cigarette box is used as the key to encrypt the plaintext data of the current cigarette box using an encryption algorithm, thus obtaining the ciphertext data.

[0023] The obtained encrypted data is used as the anti-counterfeiting code for the current cigarette box, thus achieving anti-counterfeiting measures for the current cigarette box.

[0024] Based on the above technical solution, the anti-counterfeiting verification process for cigarette boxes specifically includes:

[0025] By illuminating the markings on the surface of the cigarette pack with an ultraviolet light source, a CCD camera is used to capture the image that appears due to the ultraviolet light illuminating the markings.

[0026] The acquired image was converted into a black and white image using MATLAB software, and each pixel of the black and white image was represented by binary data to obtain the corresponding binary data.

[0027] Based on the obtained binary data, the anti-counterfeiting code of the current cigarette box is decrypted using a decryption algorithm to obtain plaintext data, thereby enabling the anti-counterfeiting verification of the current cigarette box.

[0028] Based on the above technical solution, the process of obtaining plaintext data to achieve anti-counterfeiting verification of the current cigarette box includes the following specific steps:

[0029] Determine whether the obtained plaintext data is consistent with the plaintext data originally corresponding to the current cigarette box stored on the server:

[0030] If so, then the current cigarette box is genuine;

[0046] This invention provides a method for anti-counterfeiting of cigarette packaging. The method involves adding a predetermined proportion of fluorescent powder to a shrinkable reverse varnish on the substrate to obtain a fluorescent reverse varnish. A marking pattern is then engraved on a gravure printing plate using electro-engraving. Based on the fluorescent reverse varnish and the engraved plate, the marking pattern is printed onto the cigarette box surface and dried. Random fluorescent images generated by the shrinkage of the fluorescent reverse varnish at the marking pattern location on the cigarette box surface are then captured and converted into binary data. Finally, the converted binary data is used to encrypt the plaintext data corresponding to the current cigarette box, thereby achieving anti-counterfeiting measures. Specifically, random patterns are generated through gravure printing, and the printed patterns are captured and identified to generate unique, physically unclonable data, thus achieving anti-counterfeiting measures for the cigarette box. This invention can be implemented without modification using existing printing equipment, resulting in high production efficiency, low production cost, and the generated random patterns are difficult for counterfeiters to replicate, giving the cigarette box strong anti-counterfeiting properties. This invention also provides a non-transitory computer-readable storage medium and a device for anti-counterfeiting of cigarette packaging.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0048] See Figure 1 As shown in the figure, an embodiment of the present invention provides a method for implementing anti-counterfeiting measures on cigarette product packaging, which specifically includes the following steps:

[0049] S1: Add a set proportion of fluorescent powder to the reverse varnish that can shrink on the surface of the substrate to obtain fluorescent reverse varnish, and engrave the logo pattern on the gravure printing plate based on the electro-engraving method.

[0050] In this invention, a fluorescent reverse varnish is obtained by adding a predetermined proportion of phosphor to a reverse varnish that can shrink on the surface of the substrate. The specific steps include:

[0051] S101: Mix the fluorescent powder with the reverse varnish that can shrink on the surface of paper-based printing substrates at a mass ratio of 2:98 to obtain a fluorescent reverse varnish with fluorescent effect.

[0052] S102: Add n-propyl acetate solvent to the obtained fluorescent reverse varnish to adjust the viscosity of the fluorescent reverse varnish, and measure the viscosity using a viscosity cup.

[0053] 98% of the reverse varnish that can shrink on the surface of paper-based printing substrates is mixed with 2% phosphor to obtain a reverse varnish with a fluorescent effect, denoted as fluorescent reverse varnish; then, n-propyl acetate solvent is added to the mixed fluorescent reverse varnish, and the viscosity of the ink is measured by a viscosity cup during the process, and the viscosity of the ink is adjusted to 13 seconds.

[0054] Specifically, for engraving logo patterns on gravure printing plates using electro-engraving, a square logo pattern with a size of 11mm × 11mm is engraved on the gravure printing plate using electro-engraving, and the engraving depth of the printing plate is 35μm. The logo pattern can be a brand logo pattern or other custom designs.

[0055] S2: Based on fluorescent reverse varnish and engraved printing plate, the identification pattern is printed on the surface of the cigarette box and then dried.

[0056] In this invention, based on fluorescent reverse varnish and an engraved printing plate, a marking pattern is printed on the surface of a cigarette box and then dried. Specific steps include:

[0057] S201: Start the gravure printing machine and set the printing speed; the printing speed can be 50m / min.

[0058] S202: Fluorescent reverse varnish is transferred to the surface of the cigarette box through the engraved printing plate, and a logo pattern is obtained on the surface of the cigarette box. The fluorescent reverse varnish in the logo pattern shrinks freely and randomly on the surface of the cigarette box.

[0059] S203: The fluorescent reverse varnish on the surface of the cigarette box is dried by the gravure printing machine drying system. The pattern printed on the surface of the cigarette box at this time is the PUF (Physically Unclonable Function) sample.

[0060] S3: Collect random fluorescent images generated by the shrinkage of fluorescent reverse varnish at the marking pattern on the surface of the cigarette box, and convert the random fluorescent images into binary data;

[0061] PUF (Programmatical Object Model) is a one-way function based on optical operation principles. It generates an infinite number of unique data information by extracting the random inherent properties of physical mechanisms. It has characteristics such as uniqueness, randomness, and non-cloning, and can be widely used in anti-counterfeiting and other fields. Combining PUF with anti-counterfeiting printing can effectively resist and combat counterfeit and shoddy products. It has a unique random physical pattern that cannot be copied and has a large number of stable random processes. It has physical patterns that are easy to record and store and can be read using appropriate analysis tools.

[0062] Reverse varnish printing is a process that has been increasingly widely used in the packaging and printing industry in recent years. Figure 2As shown, the reverse varnish shrinks on the substrate surface due to the surface tension of the liquid, and then dries and cures to obtain the printed pattern. Under the premise that the printing process remains unchanged, the shrinkage process of the reverse varnish due to the surface tension of the liquid is a random process. The small bumps formed after each image shrinks and dries are completely different. If the image printed with the reverse varnish is diffusely reflected by a scattering body, optical speckle can be obtained. According to the formation principle of optical speckle, the formed optical speckle has randomness and uniqueness. Therefore, random and unclonable optical speckle can be obtained. This random and unique optical speckle pattern can be used for anti-counterfeiting treatment of cigarette boxes.

[0063] Furthermore, to further enhance anti-counterfeiting performance, since the reverse varnish is a colorless and transparent ink, when a certain proportion of fluorescent powder is added to the reverse varnish, the printed pattern will emit fluorescence of a specific wavelength under ultraviolet light, resulting in a random and unclonable fluorescent pattern, thus achieving anti-counterfeiting treatment for the cigarette box. By combining printed PUF anti-counterfeiting with fluorescent anti-counterfeiting functions, the performance of printed PUF anti-counterfeiting is greatly improved.

[0064] In this invention, random fluorescent images generated by the shrinkage of fluorescent reverse varnish at the marking pattern on the surface of the cigarette box are collected, and the random fluorescent images are converted into binary data. Specific steps include:

[0065] S301: By illuminating the marking pattern on the surface of the cigarette box with an ultraviolet light source, a CCD (Charge Coupled Device) camera is used to capture the random fluorescent image that appears due to the ultraviolet light irradiation; the marking pattern is excited to fluoresce under ultraviolet light irradiation, and a fluorescent image can be obtained by taking a picture. The fluorescent powder is affected by the shrinkage of the reverse varnish on the surface of the substrate due to the surface tension of the liquid, and its arrangement changes randomly, so the fluorescent image obtained is a random and unique image.

[0066] S302: The acquired random fluorescence images are converted into black and white images using MATLAB software. The binary data corresponding to the random fluorescence image is obtained by representing each pixel of the black and white image using binary data. For a black and white image, each pixel can be represented using binary data. By representing each pixel in the black and white image using binary data, the binary data corresponding to the random fluorescence image can be obtained.

[0067] S4: Encrypt the plaintext data corresponding to the current cigarette box using the converted binary data to achieve anti-counterfeiting processing of the current cigarette box.

[0068] In this invention, the plaintext data corresponding to the current cigarette box is encrypted using the converted binary data to achieve anti-counterfeiting measures for the current cigarette box. Specific steps include:

[0069] S401: Obtain the plaintext data corresponding to the current cigarette box, and each cigarette box corresponds to a unique plaintext data;

[0070] S402: Use the binary data obtained from the conversion of the current cigarette box as the key, and encrypt the plaintext data of the current cigarette box using an encryption algorithm to obtain ciphertext data;

[0071] S403: Use the obtained encrypted data as the anti-counterfeiting code for the current cigarette box to achieve anti-counterfeiting measures. There is a one-to-one correspondence between the obtained anti-counterfeiting code and the cigarette box. The anti-counterfeiting code can be printed on the cigarette box or stored in the server.

[0072] In this invention, the anti-counterfeiting verification process for cigarette boxes specifically includes:

[0073] S4031: By illuminating the markings on the surface of the cigarette box with an ultraviolet light source, a CCD camera is used to capture the image that appears due to the ultraviolet light irradiation.

[0074] S4032: Convert the acquired image into a black and white image using MATLAB software, and represent each pixel of the black and white image in binary to obtain the corresponding binary data of the black and white image;

[0075] S4033: Based on the obtained binary data, the anti-counterfeiting code of the current cigarette box is decrypted using a decryption algorithm to obtain plaintext data, thereby realizing the anti-counterfeiting verification of the current cigarette box.

[0076] In other words, when verifying the anti-counterfeiting of cigarette boxes, the system uses an ultraviolet light source to illuminate the marking pattern on the surface of the cigarette box to obtain the binary data corresponding to the image, acquires the anti-counterfeiting code corresponding to the current cigarette box, and then decrypts the anti-counterfeiting code of the current cigarette box based on the binary data and through a decryption algorithm to obtain plaintext data, thereby realizing the anti-counterfeiting verification of the current cigarette box.

[0077] In this invention, plaintext data is obtained to achieve anti-counterfeiting verification of the current cigarette box. The specific steps include:

[0078] Determine whether the obtained plaintext data is consistent with the plaintext data originally corresponding to the current cigarette box stored on the server:

[0079] If so, then the current cigarette box is genuine;

[0080] If not, then the current cigarette box is a counterfeit product.

[0081] Because the random fluorescent images on the surface of cigarette boxes are unique and cannot be reproduced, even if criminals print the anti-counterfeiting code of genuine cigarette boxes onto counterfeit cigarette boxes, the binary data corresponding to the random fluorescent images on the surface of the counterfeit cigarette boxes cannot be decrypted from the genuine anti-counterfeiting code on the cigarette boxes.

[0082] Furthermore, even if criminals generate corresponding anti-counterfeiting codes based on the random fluorescent images of counterfeit cigarette boxes when making them, that is, matching the random fluorescent images on the surface of the counterfeit cigarette boxes with the anti-counterfeiting codes on the counterfeit cigarette boxes, the plaintext data obtained on the counterfeit cigarette boxes during anti-counterfeiting verification is inconsistent with the plaintext data stored in the server.

[0083] This invention utilizes the random and non-clonable characteristics of random fluorescent images to completely prevent criminals from counterfeiting cigarette boxes.

[0084] The following combination Figure 3 The present invention provides a detailed description of the method for implementing anti-counterfeiting measures on cigarette product packaging.

[0085] The first step is to prepare printed PUF samples: 98% of the reverse varnish that can shrink on the surface of paper substrates is mixed with 2% of fluorescent powder to obtain fluorescent reverse varnish with fluorescent effect. Propyl acetate solvent is added to the mixed fluorescent reverse varnish. During this process, the viscosity of the ink is measured by a viscosity cup and the viscosity of the ink is adjusted to 13 seconds. The logo pattern is engraved on the gravure printing plate by electro-engraving to achieve gravure printing.

[0086] The second step is sample image signal acquisition: Based on the fluorescent reverse varnish and the engraved printing plate, the identification pattern is printed on the surface of the cigarette box, which is the printed PUF sample. The printed PUF sample is then irradiated with an ultraviolet light source to obtain a fluorescent PUF sample. Then, the image signal is acquired by a CCD camera to obtain a random fluorescent image.

[0087] Finally, there is the data processing module: the collected random fluorescence images are converted into binary data using MATLAB software, and then the converted binary data is processed to test the randomness and uniqueness of the data, which can then be used for anti-counterfeiting processing of cigarette boxes.

[0088] The PUF generation method of this invention can be achieved using existing gravure printing equipment without any modification to the equipment. The generation method is simple, low-cost, and offers high reliability and uniqueness, solving the problem of mass production of PUFs through printing. Furthermore, adding fluorescent powder to the reverse varnish combines fluorescent anti-counterfeiting with PUF anti-counterfeiting measures, further enhancing the anti-counterfeiting properties of the sample.

[0089] The method for anti-counterfeiting of cigarette packaging according to this invention involves adding a set proportion of fluorescent powder to a reverse varnish that can shrink on the surface of the substrate to obtain a fluorescent reverse varnish. A marking pattern is then engraved on a gravure printing plate using electro-engraving. Based on the fluorescent reverse varnish and the engraved plate, the marking pattern is printed on the surface of the cigarette box and dried. Random fluorescent images generated by the shrinkage of the fluorescent reverse varnish at the marking pattern location on the cigarette box surface are then collected and converted into binary data. Finally, the converted binary data is used to encrypt the plaintext data corresponding to the current cigarette box, thereby achieving anti-counterfeiting treatment for the current cigarette box. In other words, random patterns are generated through gravure printing, and the printed patterns are collected and identified to generate physically unclonable data with a unique identifier, thus achieving anti-counterfeiting treatment for the cigarette box. This invention can be implemented without modification using existing printing equipment, has high production efficiency and low production cost, and the randomly generated patterns are difficult for counterfeiters to imitate, thus giving the cigarette box strong anti-counterfeiting properties.

[0090] In one possible implementation, the present invention also provides a non-transitory computer-readable storage medium located in a PLC (Programmable Logic Controller) controller. The storage medium stores a computer program that, when executed by a processor, implements the steps of the method for implementing anti-counterfeiting measures for cigarette product packaging.

[0091] A set proportion of fluorescent powder is added to a reverse varnish that can shrink on the surface of the substrate to obtain a fluorescent reverse varnish. The logo pattern is then engraved on the gravure printing plate using an electro-engraving method.

[0092] Based on fluorescent reverse varnish and engraved printing plates, the identification pattern is printed on the surface of the cigarette box and then dried.

[0093] Collect random fluorescent images of the marking patterns on the surface of cigarette boxes caused by the shrinkage of fluorescent reverse varnish, and convert the random fluorescent images into binary data;

[0094] The plaintext data corresponding to the current cigarette box is encrypted using the converted binary data to achieve anti-counterfeiting measures for the current cigarette box.

The acquired image was converted into a black and white image using MATLAB software, and each pixel of the black and white image was represented by binary data to obtain the corresponding binary data. Based on the obtained binary data, the anti-counterfeiting code of the current cigarette box is decrypted using a decryption algorithm to obtain plaintext data, thereby enabling the anti-counterfeiting verification of the current cigarette box.

5. The method for achieving anti-counterfeiting of cigarette product packaging as described in claim 4, characterized in that, The process of obtaining plaintext data to verify the authenticity of the current cigarette box includes the following steps: Determine whether the obtained plaintext data is consistent with the plaintext data originally corresponding to the current cigarette box stored on the server: If so, then the current cigarette box is genuine; If not, then the current cigarette box is a counterfeit product.

6. A non-transitory computer-readable storage medium having a computer program stored thereon, characterized in that, When executed by a processor, the computer program implements the steps of the method for implementing anti-counterfeiting measures for cigarette product packaging as described in any one of claims 1 to 5.

7. A device for anti-counterfeiting of cigarette product packaging, characterized in that, include: The module is used to add a set proportion of fluorescent powder to a reverse varnish that can shrink on the surface of the substrate to obtain a fluorescent reverse varnish, and to engrave the logo pattern on the gravure printing plate based on electro-engraving. The printing module is used to print the logo pattern on the surface of the cigarette box based on fluorescent reverse varnish and engraved printing plate and then dry it. The acquisition module is used to acquire random fluorescent images generated by the shrinkage of fluorescent reverse varnish at the marking pattern on the surface of the cigarette box, and convert the random fluorescent images into binary data. The anti-counterfeiting module is used to encrypt the plaintext data corresponding to the current cigarette box through the converted binary data, so as to achieve anti-counterfeiting processing of the current cigarette box; The specific steps of adding a predetermined proportion of phosphor to a reverse varnish that can shrink on the surface of the substrate to obtain a fluorescent reverse varnish include: Fluorescent powder is mixed with a reverse varnish that can shrink on the surface of paper-based printing substrates at a mass ratio of 2:98 to obtain a fluorescent reverse varnish with fluorescent effect. Propyl acetate solvent was added to the obtained fluorescent reverse varnish to adjust its viscosity, and the viscosity was measured using a viscosity cup. The process of collecting random fluorescent images generated by the shrinkage of fluorescent varnish at the marking pattern on the surface of the cigarette box and converting these random fluorescent images into binary data includes the following steps: By illuminating the markings on the surface of the cigarette pack with an ultraviolet light source, a CCD camera is used to capture random fluorescent images that appear due to the ultraviolet light irradiation. The acquired random fluorescence images were converted into black and white images using MATLAB software. The binary data corresponding to the random fluorescence images were obtained by representing each pixel of the black and white images in binary form.
