A method and device for binding items to on-chain data

Abstract

This invention proposes a method and device for binding items to on-chain data based on blockchain-based Internet of Things (IoT) information to prevent counterfeiting. This method addresses the problems of counterfeiting and the low cost of counterfeiting associated with existing anti-counterfeiting technologies. This invention utilizes sealed packaging boxes / bags, an air pressure switch, and a security chip module to effectively bind the product and its identity information, ensuring the authenticity of data uploaded to the blockchain or cloud, and preventing counterfeiting. Compared to existing anti-counterfeiting technologies that rely solely on irreversible physical structures or simply affix QR codes or NFC chips to items, this invention ensures the authenticity of on-chain data, significantly improving system security and significantly reducing the difficulty and cost of counterfeiting.

Description

Technical Field

[0001] The present invention relates to the Internet of Things and blockchain technology, and in particular to a method and device for binding items to blockchain data. Technical Background

[0002] A major challenge with current blockchain-based anti-counterfeiting and traceability technologies is the inability to effectively bind the data on the blockchain to the item. Consequently, most blockchain-based anti-counterfeiting and traceability systems suffer from a significant vulnerability: item swapping, resulting in the data on the blockchain appearing authentic, but the actual item being counterfeited. Existing anti-counterfeiting packaging boxes typically utilize a special design that irreversibly damages the box once opened by the consumer, rendering it unrecyclable and counterfeit. However, it's possible that, if the item's value is high enough, the packaging itself can be counterfeited at low cost. Alternatively, a manufacturer could leak the box, allowing criminals to obtain it through channels and insert counterfeit goods to create a fake, authentic product. This presents a challenge that existing anti-counterfeiting technologies struggle to address. Another approach involves attaching a QR code or attaching an NFC chip to the item. However, since this method lacks effective binding between the item and the QR code / NFC chip, it can be easily swapped and counterfeited, and the data on the blockchain does not correspond to the authentic item.

[0003] How to effectively bind the data of items and on-chain data and quickly identify whether the items in the packaging box / box have been damaged or swapped is an urgent problem that technicians in this field need to solve. Summary of the Invention

[0004] In response to the deficiencies in the prior art, the present invention provides a method and device for binding items to on-chain data, which can effectively bind items to on-chain data and quickly identify whether the items in the packaging box / generation have been damaged or swapped, thereby preventing the malicious damage or swapping of items in the packaging box / generation.

[0005] The technical solution of the present invention is achieved as follows:

[0006] A method and device for binding an item to blockchain data, including hardware components:

[0007] The anti-counterfeiting chip module includes: battery, data microprocessor chip, air pressure switch / sensor, light switch / sensor, and Bluetooth switch; put the anti-counterfeiting chip module into a sealed box / bag, and after pumping / inflating, once the sealed box / bag is opened or the outer packaging is damaged, resulting in air leakage, the air pressure switch / sensor is turned on or the light switch / sensor is turned on, the microprocessor chip will detect it and the data processing chip will erase or change the internal product information and private key of the anti-counterfeiting chip module to achieve effective binding between the item and the public key in the chain database; in the anti-counterfeiting chip module, the light switch / sensor and the air pressure switch / sensor can control the data information of the data processing chip.

[0008] A method and device for binding an item to blockchain data, including software components:

[0009] Supply chain data chain includes supply chain data chain download, supply chain data chain upload, product QR code, automatic negotiation to generate a pair of passwords - public key and private key, item traceability data signature based on the private key and traceability data verification based on the public key; the mobile app scans the product QR code on the packaging box / bag, connects to the anti-counterfeiting chip module via Bluetooth, closes the packaging box / bag, and then evacuates or inflates the packaging box / bag through the inflation hole or exhaust hole. When the air pressure of the packaging box / bag after evacuation or inflation reaches a value lower than the negative pressure data initialization pressure value or the air pressure after inflation is greater than the data initialization pressure value, the anti-counterfeiting chip module data is initialized, and then the mobile app can fill in the relevant information of the item. After the item information is filled in and submitted, the item information is uploaded to the supply chain data chain library and the anti-counterfeiting chip module. At the same time, the anti-counterfeiting chip module and the supply chain data chain library automatically negotiate to generate a pair of public / private keys. The anti-counterfeiting chip module stores the private key, and the chain database stores the public key. When checking to see if the item has been swapped or the packaging / bag has been damaged, if the packaging / bag is intact, the anti-counterfeiting chip module information is intact, and the public and private keys are mutually verified. If the item has been swapped or the packaging / bag has been damaged, the air pressure switch / sensor and light switch / sensor of the anti-counterfeiting chip module detect changes in air pressure or light inside the packaging / bag. The microprocessor chip then detects this and erases or changes the product information and private key within the anti-counterfeiting chip module. The mobile app connects to the data processing chip of the anti-counterfeiting chip module via Bluetooth. If the packaging / bag has not been swapped or damaged, the mobile app will display complete item information. When you click Verify, the public and private keys are mutually verified. If the packaging / bag has been swapped or damaged, the mobile app will display "no item information" or garbled characters.

[0010] As a further technical solution, a method and apparatus for binding an item to on-chain data also includes:

[0011] The anti-counterfeiting chip module has two mobile app connection methods: Bluetooth connection and NFC connection.

[0012] Preferably, the Bluetooth connection is highly compatible with various mobile phones.

[0013] Preferably, when the anti-counterfeiting chip module is in standby mode, Bluetooth is in dormant mode and needs to be manually activated to wake up when in use.

[0014] Preferably, the battery on the anti-counterfeiting chip module is 600 mAh, which can provide the anti-counterfeiting chip module with 6 years of use in standby mode.

[0015] Preferably, the light-sensitive switch / sensor on the anti-counterfeiting chip module can receive visible light and invisible light, including infrared and ultraviolet rays.

[0016] Preferably, the air pressure switch / sensor is divided into a positive air pressure switch / sensor and a negative air pressure switch / sensor.

[0017] The technical solution of the present invention is to place an anti-counterfeiting chip module with an air pressure switch / sensor (which turns on after reaching a certain air pressure value) into a sealed packaging box / bag, inflate or evacuate the packaging box / bag to reach a certain air pressure value, close the air pressure switch / sensor, initialize the chip anti-counterfeiting module, write the product-related information and submit it, and negotiate and initialize to automatically generate public and private keys; once the packaging box / bag is opened or damaged at any position, resulting in air leakage, the air pressure switch sensor or light-sensitive switch / sensor turns on, and the microprocessor chip detects it and erases or changes the product information and private key inside the anti-counterfeiting chip module; when verifying the product through the traceability data and public key pre-stored in the smart contract on the blockchain, it will be found that the product information and private key cannot be verified, so it can be determined that the item and packaging box / bag have been opened or damaged in the intermediate process, and it can be inferred that the product may have been swapped or counterfeited.

[0052] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0053] As shown in Figures 1, 2, 5, and 6, the present invention proposes a method and device for binding an item to on-chain data: A method and device for binding an item to on-chain data includes:

[0054] The anti-counterfeiting chip module includes a battery A1, a data processor chip B1, an air pressure switch / sensor C1, a light-sensitive switch / sensor D1, a Bluetooth switch H1, a positive air pressure switch / sensor E, and a negative air pressure switch / sensor F. Put the anti-counterfeiting chip module into a sealed box / bag. Figure 4 After pumping / inflating at M1 and M2, once the sealed packaging box / bag is Figure 5 If the box / bag is opened or the outer packaging is damaged, the air pressure switch / sensor C1 opens or the light switch / sensor D1 detects a light source. After the microprocessor chip detects it, it erases or changes the product information and private key inside the anti-counterfeiting chip module, thereby achieving effective binding between the item and the chain data; in the anti-counterfeiting chip module, the light switch / sensor D1 and the air pressure switch / sensor C1 can control the data information of the data processing chip B.

[0055] Furthermore, the supply chain data microprocessor chip includes: the traceability data public key pre-stored in the smart contract on the blockchain and the private key stored in the anti-counterfeiting chip module to verify the product. The mobile phone app scans the code to connect Bluetooth to the anti-counterfeiting module for verification. If the verification is passed, it proves that the items in the packaging box / bag have not been swapped or the packaging is damaged; if the verification fails, it proves that the items in the packaging box / bag have been swapped or the packaging is damaged, thereby achieving the anti-counterfeiting effect.

[0056] Furthermore, the light-sensitive switch / sensor; the air pressure switch / sensor includes a positive air pressure switch / sensor and a negative air pressure switch / sensor;

[0057] The light-sensitive switch / sensor can receive visible light and invisible light, including infrared and ultraviolet light.

[0058] The air pressure switch / sensor detects the air pressure inside the packaging box / bag. Once the sealed packaging box / bag is opened, the air pressure switch / sensor detects the air pressure abnormality and opens the air pressure switch / sensor C1 or C2. After the microprocessor chip detects it, it erases or changes the product information and private key inside the anti-counterfeiting chip module. In order to cope with the pressure difference caused by uneven air pressure around the world, the air pressure inside and outside the packaging box / bag may be similar. After the packaging box / bag is torn open, the air pressure switch cannot identify the air pressure change inside and outside the packaging box / bag. A photosensitive switch / sensor is used, and the photosensitive switch / sensor D1 can receive visible light and invisible light, including infrared and ultraviolet rays; when the packaging box / bag is sealed, no light can enter the interior of the packaging box / bag; the photosensitive switch / sensor detects the light inside the packaging box / bag; when the packaging box / bag is damaged and light enters the interior of the packaging box / bag, the photosensitive switch / sensor detects the light, and the microprocessor chip monitors it and erases or changes the product information and private key inside the anti-counterfeiting chip module; the double anti-counterfeiting ensures that the packaging box / bag is not swapped or damaged.

[0059] The positive air pressure switch / sensor, negative air pressure switch / sensor and light-sensitive switch / sensor; the air pressure switch / sensor is the main anti-counterfeiting technology, and the light-sensitive switch / sensor is a supplementary anti-counterfeiting technology.

[0060] like Figure 3 , 4 and as Figure 1, 2, 5, and 6 show a method and device for binding an item to chain data, including a software part: supply chain data chain including supply chain data chain downloading, supply chain data chain uploading, product QR code, automatic negotiation to generate a pair of passwords - public key and private key, item traceability data signature based on the private key and supply chain traceability data verification based on the public key; the mobile phone app scans the product QR code on the packaging box / bag, connects to the anti-counterfeiting chip module via Bluetooth, closes the packaging box / bag, and evacuates or inflates the packaging box / bag through the inflation hole or the exhaust hole. When the air pressure of the packaging box / bag after evacuation or inflation reaches a value lower than the initialization pressure value of the negative pressure data or the air pressure after inflation is greater than the data initialization pressure value, the data of the anti-counterfeiting chip module is initialized, and then the mobile phone app can fill in the relevant information of the item. After the item information is filled in and submitted, the item information is uploaded to the supply chain data chain library and the anti-counterfeiting chip module. At the same time, the anti-counterfeiting chip module and the supply chain data chain library automatically negotiate to generate a pair of public / private keys, and the anti-counterfeiting chip module stores the private key, and the chain database stores the public key. When checking to see if the item has been swapped or the packaging / bag has been damaged, if the packaging / bag is intact, the anti-counterfeiting chip module information is intact, and the public and private keys are mutually verified. If the item has been swapped or the packaging / bag has been damaged, the air pressure switch / sensor and light switch / sensor of the anti-counterfeiting chip module detect changes in air pressure or light inside the packaging / bag. The microprocessor chip then detects this and erases or changes the product information and private key within the anti-counterfeiting chip module. The mobile app connects to the data processing chip of the anti-counterfeiting chip module via Bluetooth. If the packaging / bag has not been swapped or damaged, the mobile app will display complete item information. When you click Verify, the public and private keys are mutually verified. If the packaging / bag has been swapped or damaged, the mobile app will display "no item information" or garbled characters.

[0061] Furthermore, the private key and the public key mutually verify the item information.

[0062] When the air pressure inside the packaging box / bag reaches a negative pressure value after deflating or exceeds a standard atmospheric pressure value after inflation, the data of the anti-counterfeiting chip module is initialized;

[0063] The private key is unique and necessary, and like the public key, is a necessary condition for verifying whether the packaging box / bag has been swapped or damaged.

[0064] The above are only preferred examples of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that the present invention may be modified in accordance with the technical solutions described in the aforementioned embodiments, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
