[0002] As an information carrier and anti-counterfeiting technology, QR code is widely used in the field of commodity anti-counterfeiting due to its large information storage capacity, strong traceability and high recognition efficiency.

[0003] The existing QR code transparent anti-counterfeiting lead seal system usually prints or sticks the QR code directly on the surface of the transparent packaging material, and uses the physical protective layer to improve the durability and damage resistance of the QR code. This design process is simple and low-cost, and can prevent physical damage and counterfeiting of the QR code to a certain extent. At the same time, the information traceability function is realized through the code scanning verification system, which provides convenience for product anti-counterfeiting and traceability. The existing technology relies more on the logical encryption and background verification of the anti-counterfeiting QR code, which can meet the basic anti-counterfeiting needs.

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 It is a system structure diagram of the present invention. DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Please see attached Figure 1 The embodiment of the present invention provides a transparent anti-counterfeiting lead sealing system with an embedded unique two-dimensional code, comprising: Anti-counterfeiting QR code, which contains timestamp, serial number and encryption information. Through the design of combining timestamp, serial number and dynamic encryption, the uniqueness and security of QR code are significantly improved, effectively preventing counterfeiting and reuse; The anti-counterfeiting card has the anti-counterfeiting QR code embedded in its transparent structure. The double-layer structure design of the anti-counterfeiting card not only enhances the physical protection performance of the QR code, but also increases the anti-counterfeiting complexity through the invisible fluorescent coating, thereby improving the reliability of the system and the level of anti-counterfeiting technology. A transparent shell, which embeds and packages the anti-counterfeiting card through a double-layer injection molding process, and the transparent shell provides high-strength physical protection to prevent the QR code from being damaged; The anti-tampering locking device is located on the transparent shell and is used to generate an irreversible damage mark after the shell is locked. The anti-tampering locking device effectively prevents the packaging shell from being reused after being destroyed through an irreversible dynamic damage design, thereby improving the overall safety of the lead sealing system; The optical anti-counterfeiting texture is embedded in the surface or inside of the transparent shell, and corresponds to the anti-counterfeiting QR code one by one. The optical anti-counterfeiting texture is combined with the QR code content to further increase the anti-counterfeiting complexity, forming a dual protection of information anti-counterfeiting and physical anti-counterfeiting; The data storage module is used to record the generation information and verification information of the anti-counterfeiting QR code and the corresponding optical anti-counterfeiting texture. The anti-counterfeiting data is stored and managed through blockchain technology, which enhances the traceability and credibility of the data and ensures the traceability and integrity of each transparent anti-counterfeiting lead seal system during use.

[0025] Please see attached Figure 1 In a preferred embodiment of the present invention, the generation of the anti-counterfeiting two-dimensional code includes the following steps: Get Timestamp , Serial Number and dynamic keys ; Specifically: The timestamp provides a unique identifier in the time dimension for each QR code, which is convenient for time tracing of anti-counterfeiting information and avoids the problem of duplicate QR codes in the same production batch. The combination of serial number and timestamp effectively avoids the problem of duplicate numbering in the same time batch, ensures the uniqueness of the QR code, and improves the information tracing capability. The introduction of dynamic keys enhances the dynamic nature of QR codes, significantly increases the difficulty of counterfeiting, and ensures its security through a daily update mechanism. The anti-counterfeiting QR code achieves a high degree of combination of dynamicity, security and non-replicability, forming a dual guarantee of information anti-counterfeiting and physical anti-counterfeiting. Generates a cryptographic hash value based on the following formula :

[0026] Specifically: The irreversibility and uniqueness of the hash value ensure the security of the QR code. Even if the hash algorithm is known, the same content cannot be forged.

[0027] The final anti-counterfeiting QR code content is generated based on the following formula: ; in The key used for elliptic curve encryption; Specifically: Through the above formula, the generated QR code content can be stored in the blockchain database together with its timestamp, serial number, and dynamic key to ensure data consistency during verification. ECC encryption further improves the security of the QR code, so that its content cannot be interpreted or tampered with even if it is intercepted.

[0028] Please see attached Figure 1 In a preferred embodiment of the present invention, the packaging of the transparent shell includes the following steps: A groove is preset in the transparent shell to accommodate the anti-counterfeiting card; Embedding the anti-counterfeiting card into the groove by a mechanical arm; The packaging is carried out using a double-layer injection molding process, wherein the first layer of injection molding forms the transparent shell body, and the second layer of injection molding completes the sealing and fixing of the anti-counterfeiting card; Specifically: first, before injection molding, the transparent shell is preset with a groove of precise size to accommodate the anti-counterfeiting card. The preset groove provides a stable embedding space for the anti-counterfeiting card to prevent the card from being displaced during the packaging process. At the same time, the overall durability and processing efficiency of the shell are improved through precision design and high-precision molding; secondly, the visual positioning system enables the robotic arm to accurately grasp the anti-counterfeiting card and embed it into the groove, thereby ensuring the automation and accuracy of the anti-counterfeiting card embedding process and improving production efficiency; at the same time, through pressure control and fixed design, the stability of the card is improved, providing a reliable foundation for subsequent packaging. Finally, the double-layer injection molding process ensures the complete integration of the anti-counterfeiting card and the shell, which not only enhances the stability of the packaging, but also prevents the movement or damage of the card. At the same time, the close combination of materials achieves excellent waterproof and dustproof properties.

[0029] Please see attached Figure 1 In a preferred embodiment of the present invention, the optical anti-counterfeiting texture of the transparent shell is generated by the following steps: The encoding value of the optical texture is generated based on the following formula:

[0030] To prevent counterfeiting, the QR code content is generated through a dynamic encryption algorithm. It is a secure hash algorithm that maps the QR code content into a fixed-length code value. The optical code value generated by the QR code content provides a one-to-one correspondence between texture and QR code, and realizes the irreversibility and uniqueness of the code value through the hash algorithm, thus improving the anti-counterfeiting performance. A dynamic optical texture corresponding to the code value is generated in the shell by using laser interference technology. The laser interference technology uses the interference effect of multiple coherent laser beams to control the intensity, phase and interference angle of the interference beams to form a unique corresponding optical pattern on the inner surface of the shell or inside the material. The pattern is highly complex and unique, difficult to copy or imitate, and provides dynamic visual features for users to quickly identify. The optical texture is bound to the anti-counterfeiting QR code one by one, and the binding logic of the optical texture and the QR code realizes two-way verification through database records. On the one hand, it enhances the synergistic effect of physical anti-counterfeiting and information anti-counterfeiting, and on the other hand, it facilitates users to quickly verify the authenticity during use.

[0031] Please see attached Figure 1 In a preferred embodiment of the present invention, the anti-tampering lock device is an irreversible dynamic anti-tampering lock, comprising: Locking trigger point, designed to lock automatically after sealing; One-time damage mark, if the shell is damaged by external force, the mark will produce irreversible cracks or discoloration.

[0032] Specifically: the locking trigger point of the anti-dismantling lock device is located in the joint area of ​​the shell, and automatic locking is achieved through a snap or latch structure. During the packaging process, when the locking trigger point is squeezed or inserted by external force, the locking mechanism is triggered, so that the shell cannot be opened after the packaging is completed. At the same time, it is set to be irreversible. Once triggered, it will show signs of damage and cannot be restored to the original state. The anti-dismantling lock device is a prior art and will not be described in detail in this article.

[0033] Please see attached Figure 1 In a preferred embodiment of the present invention, the transparent shell is made of the following materials: Modified polycarbonate, as the main material, is used to improve the impact resistance. Modified polycarbonate provides excellent impact resistance while maintaining the transparency and processing stability of the shell, effectively improving the durability and reliability of the transparent anti-counterfeiting lead seal system; Nano-aluminum oxide film is used to enhance the scratch resistance and UV resistance of the surface. The nano-aluminum oxide film significantly improves the scratch resistance of the shell surface and extends the service life of the product. Its UV resistance prevents the shell from aging due to long-term exposure to sunlight, ensuring the long-term stability of the product's appearance quality and anti-counterfeiting performance. Trace ceramic powder is embedded to improve the hardness and weather resistance of the shell. The addition of trace ceramic powder improves the hardness and weather resistance of the shell, enabling it to maintain excellent protection capabilities in extreme environments (such as high temperature, low temperature, strong acid and alkali), thereby improving the overall quality of the product.

[0034] Please see attached Figure 1 In a preferred embodiment of the present invention, the anti-counterfeiting card comprises: The inner bearing layer is used to store the anti-counterfeiting QR code information. The inner bearing layer ensures the storage stability and recognizability of the anti-counterfeiting QR code through high-precision laser etching technology, and provides long-term physical protection to prevent the QR code from becoming invalid due to external damage; The outer protective layer adopts a highly transparent coating structure to enhance the card's wear resistance and long-term stability. The outer protective layer improves the card's wear resistance and long-term stability through the combination of highly transparent coating and anti-wear particles, ensuring that the anti-counterfeiting QR code remains intact and clear under high-frequency use conditions; The fluorescent coating is embedded with nano fluorescent particles and can reveal invisible anti-counterfeiting information through illumination with a light source of a specific wavelength. The fluorescent coating provides an additional verification method using invisible anti-counterfeiting technology. Its invisible characteristics increase the difficulty of counterfeiting and enhance the user's intuitive experience during the anti-counterfeiting verification process.

[0035] Please see attached Figure 1 In a preferred embodiment of the present invention, the data storage module records the following information through blockchain technology: The anti-counterfeiting QR code generates a timestamp. The timestamp record provides the uniqueness and time traceability of the QR code, effectively preventing security risks caused by repeated generation or forged time information; The serial number of the anti-counterfeiting QR code provides an independent digital identity for each QR code, which, combined with the timestamp, further enhances the uniqueness and verification reliability of the anti-counterfeiting information; Encrypted hash value of the anti-counterfeiting QR code ,The record of encrypted hash value ensures the integrity and non-tamperability of the anti-counterfeiting QR code content, further enhancing the security of anti-counterfeiting information; Optical texture encoding value ,The recording of optical texture coding values ​​provides an additional level of physical property verification for the anti-counterfeiting system, and achieves dual protection of information anti-counterfeiting and physical anti-counterfeiting through data binding; The production batch and packaging status of anti-counterfeiting cards and shells. The records of production batch and packaging status provide comprehensive production information traceability for anti-counterfeiting products, enhancing product quality management and user trust; The data storage module uses blockchain technology to achieve efficient storage and full life cycle management of anti-counterfeiting information, providing comprehensive security protection and efficient verification mechanism for the transparent anti-counterfeiting lead seal system.

[0036] Please see attached Figure 1 In a preferred embodiment of the present invention, the injection molding process parameters of the packaging process are dynamically adjusted by the following formula:

[0037] Among them, Poptimal is the optimal injection pressure, T is the injection temperature, V is the injection speed, is the characteristic parameter of the shell material; Specifically: The above dynamic adjustment formula realizes precise control of the injection molding process, avoids defects or mismatch problems in the shell caused by excessively high or low pressure and speed, and improves the packaging quality and consistency.

[0038] Please see attached Figure 1 In a preferred embodiment of the present invention, the system has a multi-layer authentication mechanism, including: First-level verification: The timestamp and serial number in the QR code are read by a scanning device and compared with the database record. The first-level verification provides a fast and intuitive basic authenticity verification, which is convenient for users to preliminarily judge the validity of the QR code and filter out the copied or forged QR codes. Second level verification: Decrypting the encrypted content of the QR code , verify the generated hash value Whether it matches, the second layer of verification is to encrypt and decrypt the hash value to ensure that the core information of the QR code has not been tampered with, which greatly improves the system's defense against high-level counterfeiting; Third level verification: by scanning optical texture Verification is performed to ensure that the shell texture corresponds to the QR code. The third level of verification further increases the technical difficulty of counterfeiting by combining physical anti-counterfeiting technology with information anti-counterfeiting, providing dual guarantees of information authenticity and physical authenticity. Through a multi-layer verification mechanism, comprehensive anti-counterfeiting management is achieved from the user end to the regulatory end, which not only improves the user experience but also enhances the security of the product throughout its life cycle.
