Description

Technical Field

[0001] This invention relates to the field of anti-counterfeiting technology, and in particular to a product anti-counterfeiting system and control method. Background Technology

[0002] Currently, supply chain management involves multiple entities, including sellers, buyers, distributors, and logistics service providers, encompassing complex transaction processes such as manufacturing, purchasing, delivery, and fund transfer. As supply chains become increasingly complex, the demand for mobility and flexibility in the flow of goods continues to grow. However, existing technologies are insufficient in terms of goods security and identity verification, making it difficult to effectively maintain the integrity of the transaction process and the credibility of data. Summary of the Invention

[0003] Therefore, it is necessary to provide a product anti-counterfeiting system and control method to solve at least one of the above-mentioned technical problems.

[0004] In a first aspect, this application provides a product anti-counterfeiting system, including a cloud management platform, terminal execution devices distributed at sales channel nodes, and anti-counterfeiting mark units combined with physical products; The product anti-counterfeiting system establishes a mapping relationship between physical products and digital rights, and controls the business status of products through a hardware locking mechanism based on bistable display. The cloud management platform is connected to the terminal execution device via a network, and the terminal execution device is connected to the anti-counterfeiting mark unit via a physical signal link. The cloud management platform is configured to maintain mapping relationships and perform logical verification and instruction issuance for business requests; The terminal execution device includes an integrated security control module and a signal generation module; the security control module is used to verify the legitimacy of the device itself and generate encrypted business requests, and the signal generation module is used to convert the verified data into specific physical signals; The anti-counterfeiting marking unit is physically attached to the physical product and includes a drive control circuit and a display layer. The drive control circuit is connected to the display layer and is used to respond to physical signals from the terminal execution device to drive the display layer to perform visual status updates, so as to update the physical appearance of the product to the status corresponding to the current circulation node or the sold status.

[0005] By establishing a mapping relationship between physical products and digital rights, a data foundation is laid for the system to manage and track the product's business status. A hardware locking mechanism based on bistable display enables physical-level control over the product's business status. Through a system architecture consisting of a cloud management platform, terminal execution devices, and anti-counterfeiting marking units, a closed loop is formed that links business logic verification with physical status updates.

[0006] In one implementation of the first aspect, the security control module consists of a microcontroller and a security encryption chip; the security encryption chip is isolated from the microcontroller through a hardware firewall, and its internal storage area is configured to store the private key certificate and device fingerprint of the terminal execution device; the microcontroller is configured to collect business environment parameters and call the security encryption chip to digitally sign the hash value of the business environment parameters in order to generate tamper-proof business requests.

[0007] A security control module consisting of a microcontroller and a security encryption chip, with digital signatures provided by the security encryption chip, ensures that business requests generated from the terminal execution device have device identity credibility and data integrity.

[0008] In one implementation of the first aspect, the signal generation module includes a near-field communication read / write module, and the anti-counterfeiting tag unit includes a radio frequency antenna; the radio frequency antenna is connected to the energy harvesting pin of the drive control circuit and is configured to sense the electromagnetic field from the near-field communication read / write module to generate an induced current; the drive control circuit is activated by the induced current and, upon receiving a valid write command, outputs a drive voltage to the display layer to change its optical display characteristics.

[0009] The energy and signal transmission link formed by the near-field communication read / write module and the radio frequency antenna enables the terminal execution device to provide working energy and transmit instructions to the anti-counterfeiting tag unit.

[0010] In one implementation of the first aspect, the hardware locking mechanism is based on the bistable display characteristics of the display layer, which is configured to maintain the current display pattern when there is no power supply; when no business verification is performed, the display layer displays a factory-preset initial pattern; after receiving a physical signal containing a verified business request, the display layer is refreshed to the target pattern, which is used to represent the current ownership information of the product or the status of completed sales.

[0011] By defining the hardware locking mechanism based on the bistable display characteristics of the display layer and defining the refresh process from the initial pattern to the target pattern, the specific method and visual representation of the mechanism to achieve physical state locking are clarified.

[0012] In one implementation of the first aspect, the terminal execution device further includes a display module configured as a source of optical communication signals; the product anti-counterfeiting system further includes a user interaction device, which includes an image acquisition component; the terminal execution device is configured to, in an offline environment, encrypt and encode sales data into a dynamic light signal sequence on the display module based on a pre-stored certificate; and the user interaction device is configured to capture the dynamic light signal sequence through the image acquisition component and extract binary data to complete offline verification.

[0013] By combining the display module of the terminal execution device with the image acquisition component of the user interaction device, an offline data verification channel based on optical communication is provided.

[0014] In one implementation of the first aspect, the cloud management platform includes an identity mapping module and a logic verification module; the identity mapping module is configured to establish a one-to-one correspondence between the unique feature code of the physical product and the non-fungible inventory token on the blockchain network; the logic verification module is configured to execute static rule verification based on identity ownership and dynamic rule verification based on the balance of inventory quantity in parallel when a business request is received, and trigger a smart contract to execute the corresponding inventory token ownership transfer or cancellation operation after the verification is passed.

[0015] The identity mapping module establishes a unique correspondence between physical products and on-chain digital rights, providing a reliable ownership basis for subsequent verification. The logic verification module executes static rule verification based on identity ownership and dynamic rule verification based on inventory balance in parallel, achieving dual verification of business requests in terms of ownership and logical consistency.

[0016] In one implementation of the first aspect, the terminal execution device also integrates a real-time clock circuit and a positioning module for collecting the timestamp and geographic coordinates of the service request; the cloud management platform also includes an anomaly analysis module, which is configured to calculate the spatiotemporal displacement velocity between two adjacent requests from the same terminal execution device; if the spatiotemporal displacement velocity exceeds a preset physical entity movement speed threshold, the anomaly analysis module determines that a spatiotemporal collision has occurred and triggers a service blocking mechanism.

[0017] The terminal execution device collects spatiotemporal data through a real-time clock circuit and a positioning module, and the cloud-based anomaly analysis module calculates the spatiotemporal displacement velocity, which can identify operational behaviors based on abnormal spatiotemporal logic and trigger blocking.

[0018] In one implementation of the first aspect, the cloud management platform also includes a task distribution module, which is configured to generate inspection tasks based on anomaly analysis results. When an abnormally high density of scanning requests is detected in a specific area, the task distribution module retrieves user terminals located near that area and pushes a QR code scanning and evidence collection task containing location information to them.

[0019] By pushing inspection tasks to user terminals based on anomaly analysis results and geographic location information through the task distribution module, the ability to conduct targeted and crowdsourced verification of suspicious areas or behaviors is realized.

[0020] In one implementation of the first aspect, the cloud management platform also includes a rights distribution module; the rights distribution module is configured such that when the status of the anti-counterfeiting mark unit is updated to the sold status and the cloud management platform receives the first QR code verification request from the consumer, the cloud management platform automatically mints a consumer rights digital asset that is different from the inventory tokens and sends it to the consumer's digital wallet.

[0021] By automatically minting and distributing consumer rights digital assets when specific conditions are met through the rights issuance module, a link is established between consumers' genuine product verification behavior and the acquisition of digital rights.

[0022] Secondly, this application provides a control method for a product anti-counterfeiting system, which is applied to the product anti-counterfeiting system in the first aspect or any implementation thereof, including: The terminal execution device collects the product's unique feature code and business environment parameters, and digitally signs the business environment parameters through the security control module of the terminal execution device to obtain a business request data packet; The terminal execution device uploads the service request data packet to the cloud management platform; The cloud management platform receives business request data packets and verifies the ownership and status of digital rights based on the mapping relationship; If the verification is successful, the cloud management platform will perform the corresponding digital rights ownership transfer or cancellation operation on the database or blockchain, and generate a verification data packet containing the current circulation status information and return it to the terminal execution device. In response to the verification data packet, the terminal execution device sends a write command and energy to the anti-counterfeiting mark unit on the product through the signal generation module; The anti-counterfeiting marking unit uses the received energy to drive the display layer to perform a physical refresh, which will irreversibly update the display content to the current circulation node status or sold status, thus completing the status locking of the physical product.

Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0025] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0026] In the description of this embodiment, unless otherwise stated, "a plurality of" means two or more.

[0027] To facilitate understanding of this plan, the following terms will be explained in detail first.

[0028] 1. Business Requests: The business requests described in this application are a collective term for various operation requests initiated by the terminal execution device 2 to the cloud management platform 1. Specifically, they include, but are not limited to: sales requests (i.e., retail operations targeting end consumers), circulation requests (including but not limited to supply chain node change operations such as warehousing, outbound, transfer, and loan display), and status query requests. In the specific embodiments described below, although sales requests or warehousing requests are often used as examples, those skilled in the art should understand that they are all specific manifestations of business requests.

[0029] 2. Business Status: Refers to the logical state of a product in the supply chain or sales process. Corresponding to different flow nodes, business status includes, but is not limited to: pending shipment, primary distributor inventory, secondary distributor inventory, sold, cancelled, etc.

[0030] 3. Mapping Relationship between Physical Products and Digital Rights: This refers to the one-to-one correspondence between physical products (identified by UIDs) in the physical world and value credentials (i.e., digital rights) in the digital world. Digital rights refer to digital assets or data records stored in cloud databases or blockchains that represent product ownership or related rights; in specific implementations, they are represented by non-fungible tokens (NFTs) or inventory tokens.

[0031] 4. Physical signal link: refers to the contactless data transmission channel established between the terminal execution device 2 and the anti-counterfeiting tag unit 3. In a specific embodiment, this link can be established via near field communication (NFC) radio frequency signals or via optical communication (optical signals).

[0032] 5. Level: This refers to the depth of a product's circulation process in the supply chain. For example, the manufacturer is defined as Level 0; the primary distributor who purchases directly from the manufacturer is defined as Level 1; the secondary distributor or retail store that purchases from the primary distributor is defined as Level 2, and so on.

[0033] 6. Hierarchical relationship: In the circulation chain, the node that currently holds the ownership of the goods is the current level, the node that transfers the goods to it is the next level, and the target node to which it will transfer the goods is the next level.

[0034] 7. Previous Level Transfer Timestamp: This refers to the time when the goods are transferred from the previous level to this level and confirmed by the cloud management platform 1. When performing the next transfer verification, the cloud management platform 1 will check whether the interval between the current time and the previous level transfer timestamp conforms to reasonable logistics and transportation logic to prevent abnormal rapid cash-out or fraudulent transfers.

[0035] This application provides a product anti-counterfeiting system 100, such as... Figure 1 As shown, exemplarily, the product anti-counterfeiting system 100 mainly includes a cloud management platform 1, a terminal execution device 2 distributed at sales channel nodes, and an anti-counterfeiting mark unit 3 integrated with the product. In some embodiments, it may also include a user interaction device 4 for receiving verification feedback.

[0036] The cloud management platform 1 serves as the backend infrastructure of the entire system, forming the main structure for data storage, rule verification, and command issuance. Internally, it includes computing units for processing inventory data and interface units for network communication.

[0037] like Figure 6As shown, the terminal execution device 2 is located at the authorized dealer's business premises or logistics node and is a hardware device that integrates data acquisition, logical operation, and physical output functions. This device is not a simple general-purpose computer, but is specially designed in terms of hardware configuration as two functionally independent but electrically connected sub-modules: a security control module 21 for identity recognition and encrypted signature, and a signal generation module 22 for physical signal interaction with the outside world.

[0038] It is understood that in some embodiments, the terminal execution device 2 also integrates a biometric acquisition module 23. The biometric acquisition module 23 includes a fingerprint sensor or an infrared face recognition camera. The fingerprint sensor is connected to the microcontroller U1 via an SPI interface and is used to collect the operator's biometric data. The microcontroller U1 compares the collected data with a whitelist in the local security zone or the cloud management platform 1. Only after the comparison is successful is the security encryption chip U2 allowed to perform signature operations.

[0039] Furthermore, to adapt to different application scenarios and enhance security, authentication methods also include account login verification or device firmware verification. Specifically, terminal execution device 2 allows operators to log in using a pre-registered mobile phone number to obtain a verification code; alternatively, when initiating a request, terminal execution device 2 automatically reads the unchangeable firmware machine code inside the device as a unique hardware ID and matches it with the cloud-based registration information, thereby achieving automatic login and authentication at the device level. This ensures that only authorized dealer accounts or specific hardware terminals can initiate valid business requests.

[0040] The anti-counterfeiting marking unit 3 is physically attached to the outer packaging or body of the product to be sold, and is used to carry the product's unique identification mark (UID) and respond to the excitation signal from the terminal execution device 2 or the user interaction device 4.

[0041] The components are structurally precisely coordinated. The cloud management platform 1 covers and manages multiple terminal execution devices 2 through network connections, providing them with a unified time reference and status data. The various modules of the terminal execution devices 2 are electrically linked to each other, jointly responding to the triggering of sales events: the security control module 21 is used to verify the legitimacy of the device itself and generate an encryption request; the signal generation module 22 converts the verified data into specific optical signals or radio frequency signals, writing the status of the anti-counterfeiting mark unit 3 or broadcasting it one-way to the user interaction device 4.

[0042] In this way, the cloud management platform 1 is responsible for storing data and operating rules. The terminal execution device 2 connects to the cloud platform and uses its internal security control module 21 and signal generation module 22 to directly write the sales status confirmed in the cloud database onto the anti-counterfeiting label of the physical product, thereby controlling the product sales process through hardware devices.

[0043] A. Terminal execution device The terminal execution device 2 serves as the front-end physical node of the product anti-counterfeiting system 100, providing an input interface for sales data, a local logic computing environment, and a verification signal transmission interface. It is typically enclosed in a rigid housing structure and integrates a motherboard, power management circuitry, and various sensor components.

[0044] In this embodiment, as Figure 2 and Figure 6 As shown, the core processing unit of the terminal execution device 2 uses a microcontroller U1. This microcontroller U1 serves as the core of data processing and is specifically selected as a high-performance, low-power 32-bit processor (such as an ARM Cortex-M series or equivalent chip). The microcontroller U1 is connected to peripheral components via conductive lines on a printed circuit board (PCB).

[0045] The terminal execution device 2 also includes a security encryption chip U2, which is electrically connected to the microcontroller U1 via an SPI interface or an I2C interface. The internal storage area of ​​the security encryption chip U2 is isolated by a hardware firewall, which refers to the hardware isolation logic or circuitry within the chip, used to store the private key certificate and device fingerprint information of the terminal execution device. This hardware structure design ensures that even if the firmware of the microcontroller U1 is read, the critical identity key cannot be exported.

[0046] In this embodiment, the terminal execution device 2 is not only used in the final sales stage, but is also distributed at various circulation nodes in the supply chain (such as primary distributor warehouses or stores, secondary distributor warehouses or stores). At this time, the encrypted request generated by the security control module 21 includes not only the basic sales request, but also a circulation confirmation request based on the operation type of the current node.

[0047] In some embodiments, such as Figure 2 As shown, the terminal execution device 2 includes a display module 221 for displaying and optical communication. The display module 221 is connected to the display driver pin of the microcontroller U1 via a parallel interface or a MIPI interface. The display module 221 is used not only to display the operation interface but is also configured as a transmitter for optical communication.

[0048] Specifically, the microcontroller U1 controls the backlight circuit or pixel matrix of the display module 221, causing it to flip on / off or switch colors at a specific frequency. This high-frequency switching may appear to the human eye as only a slight flicker on the screen or a fixed image display, but when captured by a high-speed camera, it constitutes a continuous stream of binary data.

[0049] The terminal execution device 2 also includes a near field communication (NFC) read / write module 222. The NFC read / write module 222 is connected to the UART interface of the microcontroller U1. The NFC read / write module 222 includes a radio frequency antenna circuit, which is arranged on the surface of the housing of the terminal execution device 2 or in a specific sensing area, for radiating an electromagnetic field of 13.56MHz or other specific frequencies to the outside world to power and read / write data to the anti-counterfeiting tag unit 3.

[0050] B. Anti-counterfeiting mark unit like Figure 3 As shown, the anti-counterfeiting tag unit 3 serves as a digital anchor point for the product in the physical world, providing machine-readable identity information and visual status feedback. It is typically composed of multiple layers of materials, including a base layer, a circuit layer 33, and a protective layer 35.

[0051] In this embodiment, the anti-counterfeiting label unit 3 adopts a passive or semi-active label structure based on electronic ink technology (E-Ink). The label structure mainly includes a substrate layer 31, an electronic ink display layer 32, a driving control circuit (circuit layer 33), and a radio frequency antenna 34.

[0052] The base layer 31, serving as the physical support for the entire anti-counterfeiting label unit 3, is made of flexible insulating materials such as polyethylene terephthalate (PET) or polyimide (PI). A pressure-sensitive adhesive layer 35 (or pressure-sensitive adhesive composite layer) is provided on the back side of the base layer 31 (i.e., the side away from the electronic ink display layer 32). This pressure-sensitive adhesive layer 35 is composed of a highly viscous material and is used not only to firmly adhere the anti-counterfeiting label unit 3 to the product packaging, but in some embodiments, this layer is also configured to have anti-transfer properties. When the label is forcibly peeled off, it will leave a mark due to pressure changes or structural damage, thus ensuring the uniqueness of the physical carrier in conjunction with the anti-counterfeiting label unit 3. The back side of the base layer 31 is coated with pressure-sensitive adhesive for firmly adhering the label to the product packaging.

[0053] To further prevent the label from being completely peeled off and transferred, this embodiment employs a physical-electronic dual anchoring mechanism. On the surface of the anti-counterfeiting label unit 3 or the product packaging surface it covers, a physical QR code or plaintext code corresponding one-to-one with the UID within the chip is printed using laser coding or UV digital printing technology. This physical coding spans the edge of the label and the product packaging (i.e., printed across the seam). If a counterfeiter attempts to tear off the electronic label, the integrity of the physical coding will inevitably be destroyed; or if the counterfeiter only copies the signal of the electronic label but cannot copy the physical seam code, the consumer can detect the anomaly when comparing the two codes.

[0054] The electronic ink display layer 32 is stacked on top of the substrate layer 31, or encapsulated within a specific windowed area of ​​the substrate layer 31. The electronic ink display layer 32 contains millions of microcapsules, each containing positively charged white particles and negatively charged black particles. By changing the direction of the electric field at both ends of the microcapsules, the movement of the particles can be controlled, thereby displaying black or white patterns.

[0055] The drive control circuit 33 is disposed on the surface or in the interlayer of the substrate layer 31, and mainly consists of a low-power drive chip U3 and its surrounding capacitors and resistors. The drive chip U3 has a non-volatile memory (such as EEPROM) for storing the product's unique identifier (UID) and the current status bit (such as ready for sale or sold).

[0056] The radio frequency antenna 34 is composed of copper foil etched on the substrate layer 31 or a printed conductive silver paste coil. The two ends of the radio frequency antenna 34 are connected to the energy harvesting pins of the driver chip U3.

[0057] Its working principle is as follows: When not verified for sale or circulation, the anti-counterfeiting marking unit 3 is in a power-off sleep state, and the electronic ink display layer 32 displays a factory-preset pattern (such as a QR code or text to be activated). Because electronic ink has bistable characteristics, maintaining this display content does not require power consumption.

[0058] The combination of this bistable display characteristic based on the display layer (such as an e-ink screen) and the driving logic of the security chip constitutes the hardware locking mechanism described in this application. Specifically, this mechanism utilizes the physical characteristic that the display medium retains its image after power is off, and in conjunction with the logic that the driving control circuit 33 only outputs a driving voltage in response to verified specific physical signals (such as encrypted NFC commands), it achieves physical-level locking of the product's business status (such as a sold status). Unless there is legitimate write permission, the display status cannot be tampered with by simply powering off or resetting.

[0059] Unlike traditional labels that only display static QR codes, the electronic ink display layer 32 in this embodiment is configured to dynamically record the product's entire lifecycle status.

[0060] When the NFC read / write module 222 of the terminal execution device 2 approaches the anti-counterfeiting tag unit 3, the radio frequency antenna 34 generates an induced current through electromagnetic induction. After rectification and voltage regulation, this current activates the driver chip U3. The driver chip U3 receives the write command from the terminal execution device 2.

[0061] If the instruction contains a valid circulation signature or sales signature, the driver chip U3 outputs a driving voltage to the electronic ink display layer 32, causing the charged particles within it to migrate and physically change the displayed pattern. The information reflected in this pattern (such as primary distributor, secondary distributor) corresponds to the state of the current circulation node. Specifically, the displayed content before verification can be defined as the initial pattern. After verification, the display layer is refreshed to the target pattern. The content of this target pattern varies depending on the business scenario, representing the product's current ownership information (such as primary distributor: [distributor name]) or the status of a completed sale (such as "sold out"). This improvement in physical structure, without relying on a continuous power supply, achieves a permanent change in the anti-counterfeiting status. Once the electronic ink display layer 32 is refreshed to a sold state, it cannot be restored to its initial state unless reversed through a valid terminal execution device 2 (which is usually logically prohibited by the cloud management platform 1). This solves the problem of packaging recycling and reuse from a physical hardware perspective.

[0062] As is understood, the hardware locking mechanism described in this application refers to a structure that combines a display medium with bistable characteristics (such as electronic ink, cholesteric liquid crystal, etc.) with a driving circuit that only responds to specific encrypted physical signals. This mechanism locks the product's appearance at the physical level, unlike purely software-based state locking.

[0063] C. User interaction device like Figure 7 As shown, the user interaction device 4 is typically a smartphone or other portable electronic device held by the consumer. In the product anti-counterfeiting system 100, the user interaction device 4 invokes its built-in general-purpose hardware components by installing an application or running a mini-program.

[0064] User interaction device 4 includes an image acquisition component 41 (such as a CMOS camera) and a display component 42 (such as a touch screen). The image acquisition component 41 is configured to have a high frame rate acquisition mode and is capable of capturing high-frequency light signals emitted by the display module 221 of the terminal execution device 2.

[0065] In some embodiments, such as Figure 4 and Figure 7 As shown, the processor of the user interaction device 4 is configured to run a specific decoding algorithm. This algorithm analyzes the video stream captured by the image acquisition component 41 frame by frame to extract the binary data carried in the optical signal. This binary data includes not only the transaction time, amount, and product UID, but also the currently bound dealer information (such as name and store location), the current status of the product (such as pending sale, loaned, or sold), and the timestamp of the previous level of circulation.

[0066] It is understandable that the user interaction device 4 can also establish a data connection with the cloud management platform 1 through a wireless communication module (such as 4G / 5G or Wi-Fi) to upload decoded data and receive verification results.

[0067] In some embodiments, the user interaction device 4 is configured to provide an environmental fingerprint comparison function when displaying the verification result. Specifically, when a consumer scans a product (whether via light signal or NFC) to obtain the information of the current distributor (such as a store in Sanlitun, Beijing), the APP or mini-program automatically retrieves the storefront photo, panoramic photo of the store environment, and business license information uploaded by the distributor during registration from the cloud management platform 1, and displays them on the same screen as the current user's GPS location map. The consumer only needs to look up and compare the real environment with the photo on the screen: if the actual location is a grocery store, but the screen displays a photo of a luxury boutique; or if the actual geographical location deviates from the store location displayed on the cloud management platform 1 by more than a preset distance (such as 500 meters); then the consumer can immediately determine that the goods are not as described or that there is illegal cross-selling, and report it with one click. This verification method based on the comparison of the physical environment of people, goods, and place greatly reduces the threshold for consumers to identify the product.

[0068] D. Abnormal Behavior Intervention System like Figure 2 As shown, although the abnormal behavior blocking function is mainly implemented by the software logic of the cloud management platform 1, at the hardware level, it relies on the clock circuit and positioning module of the terminal execution device 2.

[0069] The mainboard of terminal execution device 2 integrates a real-time clock (RTC) circuit, which is powered by an independent coin cell battery to ensure accurate timekeeping even in the event of a power outage or network interruption. The RTC circuit provides an unalterable hardware timestamp for each sales request.

[0070] In addition, the terminal execution device 2 also integrates a Global Navigation Satellite System (GNSS) receiver module or a Wi-Fi positioning probe. These hardware components collect the device's geographic coordinate data in real time and encapsulate it as part of the metadata in the data packet of the sales request. The cloud management platform 1 uses AI algorithms to calculate the spatiotemporal distance based on this location and time data physically collected by the hardware, thereby identifying and blocking abnormal sales behavior.

[0071] E. Cloud Management Platform The cloud management platform 1 is physically composed of a server cluster, but logically, in this embodiment, it is configured as multiple mutually coupled modules. It is understood that these modules are computer program instructions stored in memory and executed by a processor.

[0072] For example, such as Figure 5 As shown, the cloud management platform 1 includes: The identity mapping module 101 is configured to maintain a mapping table between physical products and digital rights. When a product leaves the factory, this module generates a globally unique identifier (UID) and calls a smart contract interface to bind this UID to a token ID on the blockchain. The identity mapping module 101 is also responsible for synchronously updating on-chain data when the product state changes, ensuring consistency between the physical and digital states. It should be noted that the digital rights described in this application are represented in specific embodiments as non-fungible tokens (NFTs) or stock tokens, representing digital ownership of the product.

[0073] The logic verification module 102 is configured to receive business requests from the terminal execution device 2 and execute static rule verification based on identity ownership and dynamic rule verification based on inventory balance in parallel.

[0074] Specifically, static rule verification based on ownership refers to the following: the logic verification module 102 extracts the terminal ID that initiated the request (representing the identity of the operating dealer) and compares it with the digital rights owner (i.e., ownership) currently recorded on the blockchain for the UID of the product to be operated. Only when the two match (for example, the NFT corresponding to the UID currently belongs to the wallet address of the primary dealer A, and the request was initiated by the terminal authorized and bound by the primary dealer A), the static rule verification is deemed to have passed. If the current owner and the operator's identity are inconsistent (for example, the ownership of the product belongs to the primary dealer, but it is scanned by the terminal of the secondary dealer), the logic verification module 102 will directly reject the unauthorized operation.

[0075] In dynamic rule verification: the logic verification module 102 performs a strict inventory balance check. The cloud management platform 1 monitors the inventory accounts of distributors at all levels in real time to ensure that the quantity of goods they issue (outflow) is strictly less than or equal to the quantity of goods they receive through legal channels (inflow). If it is detected that a distributor is attempting to sell or transfer goods exceeding their current inventory balance (i.e., excess quantity), or if the UID has been marked as sold or transferred in the database of the cloud management platform 1, the logic verification module 102 will determine it as an inventory anomaly or a double-spending attack, directly triggering the highest level of blocking mechanism and returning a rejection instruction to the terminal without manual review. If the verification passes, the logic verification module 102 triggers the smart contract to execute the corresponding inventory token ownership transfer (for transfer requests) or cancellation operation (for sales requests).

[0076] Anomaly Analysis Module (not shown in the diagram): To support the determination of complex violations, the cloud management platform 1 also includes an anomaly analysis module. This module can exist independently or as a sub-module of the logic verification module 102. The anomaly analysis module is configured to specifically process spatiotemporal data and behavior frequency data to determine whether there are abnormal behaviors such as spatiotemporal collisions or machine-generated order fraud, and trigger a business blocking mechanism accordingly.

[0077] The task distribution module 103 is configured as a location-based dynamic scheduling center. In one embodiment, when the anomaly analysis module (not shown in the figure) in the cloud management platform 1 detects a high density of abnormal barcode scanning requests in a certain area (e.g., frequent secondary scanning of sold products by an unauthorized store), the task distribution module 103 automatically generates an investigation task. This module retrieves user terminals with high credit ratings located near the area and pushes paid barcode scanning and evidence collection tasks to them through the application, thereby constructing a distributed monitoring network.

[0078] It should be noted that the user terminal described in this embodiment includes both ordinary consumer user terminals (used for crowdsourcing auditing) that hold user interaction devices 4 and brand-authorized auditing terminals that hold dedicated equipment.

[0079] The financial credit interface module 104 is configured to interact with external financial institution systems. In one embodiment integrating supply chain finance, this module aggregates the compliant sales rate and inventory turnover rate data of each distributor in real time. This data, without human intervention, is directly pushed to the bank's credit risk control system as an objective basis for providing dynamic credit lines (such as inventory-backed financing) to distributors.

[0080] In one embodiment, the cloud management platform 1 further includes a rights issuance module (not shown in the figure), configured as a minting and distribution center for digital assets. This module is connected to the identity mapping module 101 and is used to monitor the state changes of the anti-counterfeiting mark unit 3. When the state of the anti-counterfeiting mark unit 3 is updated to a sold state, and the cloud management platform 1 receives the first QR code verification request from the consumer, the rights issuance module automatically invokes the smart contract to mint consumer rights digital assets (such as consumer NFTs) that are distinct from the inventory tokens, and sends them to the consumer's digital wallet.

[0081] F. Product Anti-counterfeiting Control Methods This application also provides a product anti-counterfeiting control method, which operates based on the hardware architecture of the aforementioned cloud management platform 1, terminal execution device 2, and anti-counterfeiting marking unit 3. For example... Figure 8 As shown, this method is implemented through the following steps: S1. The cloud management platform obtains product production information and performs mapping and binding operations to obtain the initialized inventory tokens and mapping relationships.

[0082] Specifically, product manufacturing information includes a unique identifier (UID) for each anti-counterfeiting label unit 3. During the product manufacturing process, the production line's reading and writing equipment reads and uploads the UID of the anti-counterfeiting label unit 3. After obtaining the UID, the cloud management platform 1 invokes an embedded smart contract to mint a non-fungible token (NFT) on the blockchain network that corresponds one-to-one with the UID, and marks the initial state of this token as locked and belonging to the brand's wallet. This establishes a unique ownership mapping between the physical product UID and the on-chain digital token in the database and on the blockchain. The production line terminal then writes the words "manufactured" and "manufacturer information" into the display layer of the anti-counterfeiting label unit 3.

[0083] S2. The terminal execution device obtains the business environment parameters, performs digital signature based on the business environment parameters, and obtains the business request data packet.

[0084] Specifically, when authorized operators at various levels of the supply chain trigger business instructions, the terminal execution device 2 collects multi-dimensional data through various sensors. This multi-dimensional data includes, in addition to, the operator's identity ID verified by the biometric module, the mobile phone number or terminal firmware code of the logged-in account, the current timestamp generated by the real-time clock circuit, the geographical coordinates obtained by the satellite positioning module, the UID of the product to be sold, and the transaction amount information, also: the current distributor's identity information and the operation type (such as warehousing, outbound, loan display, final sale). Subsequently, the microcontroller U1 calls the security chip U2, which is isolated by the hardware firewall, to digitally sign the hash value of the above information using the device private key stored in the chip, and encapsulates the original data with the signature to generate a tamper-proof sales request data packet.

[0085] It should be noted that the multi-dimensional data collected in this embodiment, including biometrics, time, geography, and UID, are collectively referred to as business environment parameters.

[0086] It should be noted that there is no restriction on the order of execution of S1 and S2.

[0087] S3. The terminal execution device sends a sales request data packet to the cloud management platform.

[0088] Specifically, the terminal execution device 2 establishes a secure connection through a network communication interface (such as a 4G / 5G / Wi-Fi module) and uploads the sales request data packet generated in step S2 to the cloud management platform 1 to initiate a legality verification request for this operation (including circulation, warehousing, or final sales). The cloud verification process corresponding to this request is collectively referred to as business verification in this embodiment.

[0089] S4. The cloud management platform performs multi-dimensional verification on the sales request data packets based on the mapping relationship to obtain the logical verification results.

[0090] Specifically, after receiving the data packet, the cloud management platform 1 performs the following verification logic in the logic verification module 102: First, the pre-stored public key is used to decrypt and verify the data packet signature to ensure that the request originates from a legitimate hardware terminal.

[0091] Secondly, extract the product UID from the data packet, query the corresponding on-chain inventory tokens in the mapping relationship established in step S1, and confirm whether the tokens exist, are available for sale, and belong to the current distributor; for example, if the request shows that the first-level distributor is issuing the goods, the logic verification module 102 checks whether the current on-chain tokens do indeed belong to the first-level distributor.

[0092] Then, the logic verification module 102 compares the shipped quantity with the scanned and entered quantity in real time. For example, if the manufacturer actually ships 1,000 items, and distributor A attempts to scan and enter the 1,001st item (i.e., attempts to mix in an illegal product), the logic verification module 102 will immediately intercept or mark the abnormal request, determine it as illegal entry: no corresponding shipping record, and generate a rejection instruction.

[0093] Finally, the spatiotemporal displacement velocity is calculated based on the timestamp and geographic coordinates in the data packet to determine whether there are abnormal behaviors such as simultaneous scanning in different locations.

[0094] S5, the cloud management platform responds to the passed logical verification result, executes token transfer and data generation operations, and obtains a verification data packet containing a dynamic anti-counterfeiting code.

[0095] Performing token transfer and data generation operations refers to the following two operations performed by the cloud management platform after verification: 1. Token Circulation Operations: Based on the type of business request, update the status of the digital rights (inventory tokens) uniquely bound to the physical product on the blockchain or database. Specifically, for circulation requests (such as shipment, warehousing, and allocation), execute the transfer of ownership of the digital rights (change of ownership). For final sales requests, execute the cancellation of the digital rights or mark them as "consumed".

[0096] 2. Data generation operation: Based on the results of the above token state change, a corresponding display instruction is generated, which specifies what content (i.e. target pattern) should be refreshed to the display layer of the anti-counterfeiting mark unit.

[0097] Specifically, if the verification passes, depending on the different business scenarios, the cloud management platform 1 executes on-chain state changes through smart contracts and generates corresponding display instructions: If the transaction is determined to be an inbound confirmation or transfer instruction, and the quantity balance verification passes, the ownership of the inventory tokens is transferred to the target distributor, and a display instruction is generated based on the distributor's hierarchical attributes. For example, if the target is a first-tier distributor A, the display instruction is generated as: First-tier distributor: [Distributor A]; if the target is a second-tier distributor B, the display instruction is generated as: Second-tier distributor: [Distributor B].

[0098] If the order is determined to be a sale order, the tokens will be destroyed or marked as consumed, and a message indicating that the order has been sold will be generated.

[0099] Simultaneously, a verification data packet is generated containing the aforementioned display instructions and the latest status information (such as the new owner's name, transfer level, status code, etc., collectively referred to as the current transfer status information). Among them, the non-sold status that changes with the supply chain (such as pending shipment, first-level distributor inventory, second-level distributor inventory, etc.) is collectively referred to as the transfer node status in this embodiment.

[0100] Subsequently, the cloud management platform 1 encapsulates the above display instructions with the latest status information (such as the new cargo owner's name, circulation level, etc., collectively referred to as the current circulation status information) to form the verification data packet that is finally sent to the terminal execution device.

[0101] It should be noted that if the verification fails in S4, this step will not be performed, resulting in the screen of the extra item remaining in the factory or black screen state, and thus preventing it from being mixed into the genuine inventory.

[0102] S6. The cloud management platform sends a verification data packet to the terminal execution device.

[0103] Specifically, the cloud management platform 1 transmits the verification data packet and verification completion signal generated in step S5 back to the terminal execution device 2 that initiated the request through the network interface, as an authorization instruction to trigger a physical state change.

[0104] S7. The terminal execution device performs physical tag refresh and voucher output operations based on the verification data packet to obtain the sold physical item and paper voucher.

[0105] Specifically, after receiving the verification data packet, the terminal execution device 2 performs dual hardware outputs: on the one hand, it drives the thermal printing module to output a paper transaction voucher printed with a QR code or watermark generated by the dynamic anti-counterfeiting code; on the other hand, it activates the NFC read / write module 222 to send a specific write command and radio frequency energy to the anti-counterfeiting marking unit 3 on the product. The anti-counterfeiting marking unit 3 uses induced current to drive its electronic ink display layer 32 to perform physical refresh. The displayed pattern is updated according to the status command in S5.

[0106] If it's a transfer, the display layer updates to the state corresponding to the current transfer node (i.e., the transfer node state). In terms of display content, this state specifically reflects the identity information of the current owner, such as: [Primary Distributor: Distributor Name], [Secondary Distributor: Distributor Name], etc. These non-sold states that change with the supply chain (such as pending shipment, primary distributor inventory, secondary distributor inventory, etc.) are collectively referred to as the transfer node state.

[0107] If it is a final sale, the display layer will be updated to show "sold" and anti-counterfeiting texture.

[0108] In this way, every change in state is accompanied by a change in physical appearance, ensuring rigid synchronization between physical objects and digital rights.

[0109] G. Abnormal Behavior Blocking In step S3 above, in order to prevent distributors from using technical means to launder counterfeit goods in bulk or engage in order-brushing, the product anti-counterfeiting system of this embodiment uses the aforementioned anomaly analysis module to execute the following blocking logic: 1. Using computational spatiotemporal displacement velocity blocking: Specifically, the anomaly analysis module records the time difference (Δt) and geographical distance (Δd) between two adjacent business requests (such as sales requests) under the same batch or the same distributor account. The anomaly analysis module calculates the displacement velocity v = Δd / Δt.

[0110] Subsequently, the anomaly analysis module compares the spatiotemporal displacement velocity v with a preset physical entity movement speed threshold. The physical entity movement speed threshold is an upper limit (e.g., 1000 km / h) set based on the theoretical maximum speed of current logistics transportation tools (such as airplanes, high-speed trains, and automobiles).

[0111] If the calculated v value exceeds the physical entity's movement speed threshold, the anomaly analysis module determines that a spatiotemporal collision has occurred and sends an anomaly signal to the logic verification module 102, thereby triggering the service blocking mechanism.

[0112] 2. Blocking high-frequency trading by analyzing its characteristics: Specifically, the anomaly analysis module counts the number of requests made by a single terminal execution device 2 within a sliding time window (e.g., 1 minute). If the number of requests exceeds a preset human operation limit (e.g., more than 30 requests per minute), the anomaly analysis module determines it as machine-generated order-brushing behavior and triggers blocking.

[0113] 3. Blocking through data consistency checks: Specifically, the logic verification module 102, in conjunction with the anomaly analysis module, verifies in real time the consistency between the distributor identity information, geographical location, and product ownership uploaded by the terminal execution device 2. The cloud management platform 1 also verifies in real time the consistency between the distributor identity information, geographical location, and product ownership uploaded by the terminal execution device 2. For example, if a terminal's registration information identifies it as Beijing distributor A, but it initiates a status change request from a geographical location in Shanghai; or if a product UID's current status on the system chain belongs to a first-level distributor, but it is scanned and requested to be shipped out by a terminal registered as a third-level distributor, the logic verification module 102 will immediately determine this as abnormal behavior (such as illegal cross-selling, counterfeit product injection, or permission theft), directly triggering the business blocking mechanism.

[0114] Among them, the business interruption mechanism (or circuit breaker mechanism) refers to the mandatory shutdown policy implemented by the cloud management platform at the software logic level for specific terminals or accounts, rather than the damage to physical circuits.

[0115] Execution Blocking Response: Specifically, once any of the above-mentioned anomaly determinations is triggered, the cloud management platform 1 immediately blacklists the device fingerprint of the terminal execution device 2 and freezes the corresponding dealer account's inventory token operation permissions. Simultaneously, the cloud management platform 1 generates an alarm message and pushes it to the brand's audit management terminal.

[0116] H. Offline two-way verification Understandably, in some embodiments, considering the possibility of network instability in certain sales scenarios, this embodiment also configures an offline verification mechanism based on inter-screen optical communication. Under this mechanism, the terminal execution device 2 establishes a local trust benchmark based on a pre-stored root certificate and offline key. The microcontroller U1 encrypts and encodes the sales data, including transaction time, amount, and product UID, and maps it to a color block flashing sequence or a QR code carousel sequence (e.g., a dynamic light signal with a frequency set to 15Hz to 30Hz) in a specific area on the display module 221. The user interaction device 4 uses the image acquisition component 41 to capture the dynamic light signal and extract the binary data stream. It then completes decryption and signature verification in an offline environment using a pre-set public key and generates a confirmation code for input into the terminal execution device 2, thereby achieving a transaction closed loop at the physical link level.

[0117] I. Incentives based on digital rights To address the issue of consumers lacking the motivation to scan QR codes for verification, it is understood that in some embodiments, this application also provides an incentive mechanism based on digital assets.

[0118] Specifically, once the anti-counterfeiting mark unit 3 is successfully written to the "sold" status and the consumer completes the first QR code verification via the user interaction device 4, the cloud management platform 1 triggers the rights distribution process through the rights distribution module. The system automatically mints a consumer rights NFT, distinct from the inventory tokens. This NFT contains the product's digital birth certificate, warranty rights, and brand membership points. This NFT is directly airdropped to the digital wallet registered by the consumer on the user interaction device 4.

[0119] Because this NFT is unique and cannot be copied, and is only generated after the product has been verified as authentic, it becomes the sole credential for consumers to confirm the authenticity of the product and obtain after-sales service. If a consumer purchases a counterfeit product (i.e., one that cannot pass the cloud-based logical verification), the NFT creation process cannot be triggered. This mechanism transforms anti-counterfeiting verification into an asset acquisition behavior, incentivizing consumers to actively participate in anti-counterfeiting checks from an incentive perspective.

[0120] J. Data Communication Protocols and Interaction Processes To ensure the accuracy and security of massive data interactions between the cloud and terminals at all levels, this embodiment does not employ the common HTTP plaintext transmission, but instead designs a compact, custom binary data transmission protocol. This protocol is designed to adapt to the characteristics of low network bandwidth and high latency in some logistics and warehousing environments.

[0121] Specifically, the communication data frame of this protocol consists of three parts: frame header, payload, and checksum tail.

[0122] Frame header: Occupies 2 bytes. The first byte is the protocol version number, used for compatibility with future firmware upgrades; the second byte is the message type identifier. This embodiment defines multiple message types, such as: 0x01 represents an inbound request, 0x02 represents a sales request, 0x03 represents an anomaly alarm (such as location mismatch), and 0x04 represents a heartbeat packet. After parsing this byte, the cloud management platform 1 can quickly distribute the data to the corresponding processing queue, improving concurrency efficiency.

[0123] The payload includes an authentication domain, an encryption service domain, and a checksum. Specifically: Identity authentication domain: includes the hardware serial number (Device ID, 4 bytes) of terminal execution device 2 and a dynamically generated random anti-replay token (Token, 16 bytes). Encrypted Business Domain: This refers to core business data encrypted using the AES-128 algorithm. Within this domain, the UID of the product to be operated, the operator's biometric hash, the current GPS / BeiDou coordinates, and the current distributor's digital signature information are encapsulated.

[0124] Checksum: Occupies 4 bytes, and usually uses the CRC32 algorithm to calculate the full frame checksum to ensure that no bit flips or packet loss occur during wireless transmission.

[0125] The following is an example of the complete communication process for confirming inventory receipt by a primary distributor: Terminal execution device 2 scans the product UID and detects that the operator has selected the warehousing mode. Terminal execution device 2 assembles a data frame, sets the message type identifier to 0x01 (warehousing), and encrypts and packages the UID and current GPS coordinates before sending it to the cloud management platform 1.

[0126] The cloud management platform 1 receives a data frame, first verifies the CRC32, and then decrypts the payload if it is correct. The cloud management platform 1 reads that the type is 0x01, and then calls the "inventory balancing algorithm" to verify the shipping record of the UID and the ownership rights of the terminal execution device 2.

[0127] If the verification passes, the cloud management platform 1 sends a response frame. The message type identifier of the response frame is set to 0x11 (database entry confirmation ACK), and the payload contains the instruction: "Write allowed, the screen display content is updated to first-level distributor: [distributor name]".

[0128] The terminal execution device 2 receives the response frame, decrypts the instruction, and writes the refresh voltage to the anti-counterfeiting mark unit 3 via NFC to complete the physical state change.

[0129] Through this closed-loop interaction, coupled with the encryption and verification of the underlying protocol, this embodiment successfully shifts the focus of anti-counterfeiting from the traditional identification of genuine and fake labels to the control of sales and circulation logic, and builds a rigorous defense system based on hardware locking, code execution, and data driving.

[0130] K. Beneficial effects Compared with the prior art, the beneficial effects of this application are: 1. This application establishes a mapping relationship between physical products and digital rights, using data logic compliance verification to replace traditional physical label appearance recognition. This method does not rely on consumers' physical identification capabilities; it only needs to verify whether the sales behavior conforms to the ownership and causal logic of digital assets, significantly improving the accuracy and objectivity of anti-counterfeiting verification.

[0131] 2. The system utilizes blockchain smart contracts to manage inventory data, ensuring its immutability through cryptographic mechanisms. Sales permissions are rigidly linked to the holding status of digital assets, preventing dealers from completing sales without holding the corresponding digital rights, effectively preventing inflated inventory and unauthorized sales.

[0132] 3. By combining inter-screen optical communication technology with bistable display technology, secure data interaction is ensured even in unstable network environments, and irreversible updates to the physical display status of the product are achieved. This mechanism guarantees a clear physical representation of the sold status and effectively prevents the recycling and reuse of product packaging.

[0133] 4. The system integrates an abnormal data analysis module. By monitoring the spatiotemporal logic and frequency characteristics of transaction requests in real time, it can proactively identify abnormal behaviors such as simulated location and batch order brushing and trigger a business blocking mechanism, thereby achieving real-time interception of illegal sales behavior.

[0134] 5. This application links the anti-counterfeiting verification process with the distribution of digital rights and credit assessment, transforming verification data into quantifiable digital assets or credit evidence, thereby increasing the enthusiasm of each node in the supply chain to participate in anti-counterfeiting verification and realizing data value-added of the anti-counterfeiting system.

[0135] 6. This application adopts passive electronic ink screen technology, which eliminates the need for batteries in the tag and drives it solely using NFC sensing current. Compared to traditional active electronic tags, its BOM cost is significantly reduced, and it is as thin and light as paper, allowing it to be used directly as a packaging sticker with no maintenance costs (no need to replace batteries).

[0136] 7. This application utilizes existing smartphones (with NFC and network connectivity) as reading and writing terminals. Distributors do not need to purchase expensive dedicated handheld devices (PDAs), and consumers do not need to download a dedicated APP (they can use a mini-program), which greatly reduces the entry barriers and training costs at each stage of the supply chain.

[0137] 8. The cloud interface (API) design of this application is compatible with existing ERP inventory management systems. Enterprises do not need to overhaul their original systems. They can achieve physical-digital synchronization of inventory simply by data mapping, which is easy to promote quickly in traditional manufacturing industries.

[0138] L. Examples of Application Scenarios To more clearly illustrate the advantages of this solution in preventing copying and transfer, the following uses a high-end alcoholic beverage product A as an example to describe its anti-counterfeiting process throughout its entire lifecycle.

[0139] 1. Manufacturing process Product A is filled on the production line. The cloud management platform 1 generates a unique UID and creates an NFT. The terminal execution device 2 writes the UID via NFC, and the display layer of the anti-counterfeiting mark unit 3 on the bottle of Product A displays: Genuine Product: [Brand Name] Production Date: March 2023. At this time, no unauthorized device can change the screen display.

[0140] 2. First-tier distributor Product A is transported to the warehouse of a primary distributor. The primary distributor scans the product into the warehouse using authorized terminal execution device 2. After verification by the cloud management platform 1, ownership of the NFT is transferred to the primary distributor. Simultaneously, utilizing the induced current during warehousing, the screen of the anti-counterfeiting marking unit 3 of product A refreshes to display: Primary Distributor: [Distributor X]. Thus, if someone attempts to switch the product during this process, the screen of the counterfeit product will not display the specific distributor name, making it easily identifiable to the naked eye.

[0141] 3. Retail stores Product A is displayed in the retail store. The store clerk can operate terminal device 2 to set it to loan / display status, and the screen will display "Not for Sale / Displaying". When a customer decides to purchase, the clerk initiates a sales request.

[0142] The cloud management platform 1 verifies the NFT, the terminal execution device 2 writes energy, and the screen of the anti-counterfeiting marking unit 3 of product A is finally refreshed to show that it has been sold [consumption time], and may display a dynamic QR code that can only be verified by the consumer.

[0143] 4. Consumer Validation Consumers scan the bottle with their mobile phones (or verify via optical communication). The cloud management platform 1 not only confirms the product's authenticity but also displays the complete distribution path from factory to distributor X to retail store Y. Consumers can view photos of the storefront and interior of the Sanlitun store in Beijing returned by the system on their devices and compare them with their current purchasing environment. If the photos show a luxury boutique while the consumer is at a roadside stall, it is immediately determined to be counterfeit or illegally sold through unauthorized channels.

[0144] Thus, the following can be achieved: (1) Counterfeit goods cannot be verified by the cloud management platform 1. Therefore, the anti-counterfeiting mark unit 3 will always remain in the initial state or be black screen. It cannot be updated to show the first-level distributor or retail store ownership information as the logistics flow. It will be rejected at any stage because the appearance does not match the actual ownership.

[0145] (2) Once Product A is shown as sold, this status is physically irreversible (unless it is destructively dismantled or the highest factory-level authority is obtained). Counterfeiters may recycle old bottles, but the screen will still show that it is sold, making it impossible to resell it as new wine through legitimate channels.

[0146] (3) Combined with the aforementioned laser marking technology, even if counterfeiters attempt to tear off the anti-counterfeiting mark unit 3, they will not be able to remove the physical marking on the main body, resulting in the separation of the code, screen, and goods.

[0147] (4) The name of the current distributor is directly displayed on the product screen. If the product appears in an unauthorized area, the inspectors do not need to scan the code and can discover the illegal cross-selling behavior by simply looking at the screen.

[0148] This application completely solves the drawbacks of traditional static QR codes being easily copied and transferred by adopting a mechanism that follows changes in the physical state of the circulation process, thus achieving true end-to-end closed-loop anti-counterfeiting.

[0149] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims. The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.

A control method for the product anti-counterfeiting system according to any one of claims 1 to 9, characterized in that, include: The terminal execution device collects the product's unique feature code and business environment parameters, and digitally signs the business environment parameters through the security control module of the terminal execution device to obtain a business request data packet; The terminal execution device uploads the service request data packet to the cloud management platform; The cloud management platform receives the business request data packet and verifies the ownership and status of digital rights based on the mapping relationship; If the verification is successful, the cloud management platform performs the corresponding digital rights ownership transfer or cancellation operation on the database or blockchain, and generates a verification data packet containing the current circulation status information and returns it to the terminal execution device. In response to the verification data packet, the terminal execution device sends a writing command and energy to the anti-counterfeiting mark unit on the product through the signal generation module. The anti-counterfeiting marking unit uses the received energy to drive the display layer to perform a physical refresh, irreversibly updating the display content to the current circulation node status or sold status, thus completing the status locking of the physical product.
