Description

Technical Field

[0001] The present invention relates to the technical field of commodity anti-counterfeiting, and in particular to a method and system for distinguishing counterfeit commodities. Background Art

[0002] With the growing prosperity of the commodity economy and the continuous advancement of science and technology, anti-counterfeiting has become a new and evolving field. Anti-counterfeiting technology refers to measures taken to achieve this goal. It accurately identifies authenticity within a certain range and is difficult to copy. Simply put, it is technology that prevents counterfeiting and imitation. It is a preventative technical measure taken to protect corporate brands, protect the market, and safeguard the legitimate rights and interests of consumers.

[0003] Currently, existing anti-counterfeiting technologies mostly involve anti-counterfeiting labels made of special materials such as laser anti-counterfeiting film and fragile paper. Traditional product anti-counterfeiting methods generally rely on traditional methods such as phone verification, SMS verification, barcode and identification code verification. However, these labels or methods are not ideal for anti-counterfeiting. The main reason is that the anti-counterfeiting patterns of traditional labels are fixed or sequentially numbered. This allows counterfeiters to completely reprint the labels or number products in a consistent pattern, making it impossible for manufacturers and merchants to distinguish the authenticity of the products from the appearance, allowing for mass counterfeiting.

[0004] Moreover, the existing product anti-counterfeiting means require the installation of a power supply on the product, which cannot be miniaturized, and if the user does not carry a mobile terminal, anti-counterfeiting verification cannot be performed. Therefore, there is an urgent need to further improve the existing anti-counterfeiting methods and systems.

[0005] Therefore, there is an urgent need to further improve existing anti-counterfeiting methods and systems. Summary of the Invention

[0006] Based on the above, it is necessary to provide a method and system for identifying counterfeit goods, which can effectively determine whether a product is a counterfeit product when the user does not carry a mobile terminal, enhance the anti-counterfeiting ability of the product, expand the scope of application of product anti-counterfeiting, and further reduce the risk of counterfeiting of the product.

[0007] The present invention proposes a method for identifying counterfeit goods, the method comprising:

[0008] Step 1: The energy harvesting module on the product is triggered by mechanical action to harvest energy, and the harvested energy is supplied to other modules on the product in the form of electrical energy;

[0009] Step 2: The security chip on the product receives the power supplied by the energy collection module, powers on, and reads the built-in anti-tamper identification bit at the same time;

[0010] Step 3: The security chip determines whether the anti-tampering identification bit is in a normal state;

[0011] Step 4: If yes, the security chip generates a random number and signs the random number using the built-in digital certificate private key to generate signature information, which is then displayed on the electronic ink screen of the product in the form of an identification code.

[0012] Step 5: The user's mobile terminal obtains signature information by scanning the identification code displayed on the electronic ink screen, and transmits the signature information to the cloud verification server via the network;

[0013] In step 6, the verification server verifies the signature information using the public key of the digital certificate of the security chip, and feeds back the result to the user's mobile terminal for identification of counterfeit goods.

[0014] Based on the above, before step 1, the method further includes:

[0015] When the product or its packaging is removed, the removal action triggers the energy collection module on the product to collect energy and power on the security chip;

[0016] The disassembly action triggers the anti-disassembly module on the product to generate a disassembly signal, and the disassembly signal is fed back to the security chip;

[0017] The security chip receives the disassembly signal and updates the anti-disassembly identification bit from a normal state to an abnormal state, wherein the normal state indicates that the commodity or the commodity packaging has not been disassembled, and the abnormal state indicates that the commodity or the commodity packaging has been disassembled.

[0018] Based on the above, the above step 3 specifically includes:

[0019] The built-in anti-tampering identification bit is stored in ciphertext, and the root key of the security chip is used to decrypt the anti-tampering identification bit ciphertext to obtain the anti-tampering identification bit plaintext;

[0020] Read the anti-tampering identification position plain text to determine whether the anti-tampering identification position plain text is in a normal state.

[0021] Based on the above, the above step 4 specifically includes:

[0022] The security chip generates a random number and obtains current first time information;

[0023] Signing the random number and the first time information using the digital certificate private key of the security chip to generate signature information;

[0024] Obtain the serial number of the security chip, package the serial number and the signature information into verification information, encrypt the verification information using the digital certificate public key of the verification server, obtain the verification information ciphertext, and present the verification information ciphertext on the electronic ink screen in the form of an identification code.

[0025] Based on the above, the above step 6 specifically includes:

[0026] The verification server uses its own digital certificate private key to decrypt the verification information ciphertext to obtain the serial number and the signature information;

[0027] The verification server searches the device library for the digital certificate public key corresponding to the security chip based on the serial number;

[0028] Verifying the signature using the digital certificate public key of the security chip;

[0029] After the signature verification is passed, the current second time information is obtained, and the time difference between the second time information and the first time information is calculated;

[0030] It is determined whether the time difference is greater than a preset threshold. If so, the product is determined to be a counterfeit product; if not, the product is determined to be a non-counterfeit product.

[0031] Based on the above, the identification code is preferably a QR code or a barcode.

[0032] The second aspect of the present invention further provides a counterfeit goods identification system, comprising: an anti-counterfeiting identification device, a mobile terminal, and a verification server; the mobile terminal and the verification server perform remote network communication; the anti-counterfeiting identification device comprises: an energy harvesting module, a security chip, and an electronic ink screen;

[0033] The energy collection module collects energy based on mechanical action and supplies the collected energy to other modules of the anti-counterfeiting identification device in the form of electrical energy;

[0034] The security chip is used to receive the electric energy supplied by the energy collection module, power on, and read the built-in anti-tampering identification bit to determine whether the anti-tampering identification bit is in a normal state; and is also used to generate a random number when it is determined that the anti-tampering identification bit is in a normal state, and use the built-in digital certificate private key to sign the random number to generate signature information;

[0035] The electronic ink screen is used to receive the signature information from the security chip and display it in the form of an identification code;

[0036] The mobile terminal is used to scan the identification code presented by the electronic ink screen to obtain signature information, and transfer the signature information to the verification server via the network;

[0037] The verification server verifies the signature information using the digital certificate public key of the security chip, and feeds back the verification result to the user's mobile terminal for secondary anti-counterfeiting verification.

[0038] Based on the above, the anti-counterfeiting identification device also includes an anti-dismantling module; when the product or the product packaging is disassembled, the disassembly action triggers the anti-dismantling module to generate a disassembly signal, and feeds back the disassembly signal to the security chip; after the security chip receives the disassembly signal, it updates the anti-dismantling identification position from a normal state to an abnormal state, where the normal state indicates that the product or the product packaging has not been disassembled, and the abnormal state indicates that the product or the product packaging has been disassembled.

[0039] Based on the above, the identification code is preferably a QR code or a barcode.

[0040] The present invention uses mechanical vibration as a power supply method to supply power to the security chip on the product, and the electronic ink screen only requires electricity when refreshing. It can still display the QR code after power failure. Therefore, there is no need to set a power supply on the product. The small size is suitable for a variety of products. Moreover, since any operation on the product will cause mechanical vibration, it ensures that the first verification process cannot be bypassed. At the same time, the first verification process adopts the physical display verification of the electronic ink screen, which can intuitively display the first verification result. The first verification can also be performed without a mobile terminal, thereby improving the convenience of judging counterfeit products and expanding the scope of application of product anti-counterfeiting.

[0041] The present invention is applicable to a variety of scenarios. For example, if the user does not carry a mobile device, the product can be verified based on whether the electronic ink screen can successfully display the identification code, making it easier to identify counterfeit goods and expanding the scope of product anti-counterfeiting. Of course, users can also use a mobile device to scan the identification code and perform advanced verification with the help of a cloud-based verification server. This dual verification method can improve the accuracy of counterfeit product identification, further enhance the anti-counterfeiting capabilities of legitimate products, and reduce the risk of legitimate products being counterfeited.

[0042] Additional aspects and advantages of the invention will become apparent from the description which follows, or may be learned by practice of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The above and / or additional aspects and advantages of the present invention will become apparent and readily understood from the following description of the embodiments with reference to the accompanying drawings, in which:

[0044] Figure 1 A flow chart of a method for identifying counterfeit goods according to the present invention is shown;

[0045] Figure 2A block diagram of a counterfeit goods identification system according to the present invention is shown. DETAILED DESCRIPTION

[0046] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0048] like Figure 1 As shown, the present invention proposes a method for distinguishing counterfeit goods, the method comprising:

[0049] Step 1: The energy harvesting module on the product is triggered by mechanical action to harvest energy, and the harvested energy is supplied to other modules on the product in the form of electrical energy;

[0050] Step 2: The security chip on the product receives the power supplied by the energy collection module, powers on, and reads the built-in anti-tamper identification bit at the same time;

[0051] Step 3: The security chip determines whether the anti-tampering identification bit is in a normal state;

[0052] Step 4: If yes, the security chip generates a random number and signs the random number using the built-in digital certificate private key to generate signature information, which is then displayed on the electronic ink screen of the product in the form of an identification code.

[0053] Step 5: The user's mobile terminal obtains signature information by scanning the identification code displayed on the electronic ink screen, and transmits the signature information to the cloud verification server via the network;

[0054] In step 6, the verification server verifies the signature information using the public key of the digital certificate of the security chip, and feeds back the result to the user's mobile terminal for identification of counterfeit goods.

[0055] It's understandable that an E-Ink screen doesn't refresh continuously. After a refresh, the refreshed image is retained, even if the battery is removed. Generally, the display will remain fine for a week; after that, the display will gradually fade. Therefore, even if the E-Ink screen runs out of power within a week, the screen content won't disappear immediately. Therefore, the E-Ink screen used in this embodiment doesn't require constant power supply; it only needs to be powered on when a refresh is required. Therefore, the energy collected by the energy harvesting module on the product, triggered by mechanical action, is sufficient to meet the power requirements for refreshes, eliminating the need for an on-product power supply. Its compact size makes it suitable for a wide variety of products.

[0056] It is understood that the mechanical action can be, but is not limited to, pressing or shaking. Since any mechanical action on the product will cause mechanical vibration, it will cause the security chip on the product to power on, read the built-in anti-tampering identification bit, and generate a random number when the anti-tampering identification bit is in a normal state. The random number is signed using the built-in digital certificate private key to generate signature information, which is then displayed on the electronic ink screen on the product in the form of an identification code, ensuring that the initial verification process cannot be bypassed.

[0057] As you can understand, since the security chip generates a different random number each time it is triggered, and this number is signed with its own digital certificate private key, a unique "anti-counterfeiting mark" (i.e., a different identification code) can be created each time, effectively preventing the possibility of others copying the anti-counterfeiting mark. Furthermore, the signature information is encrypted using the security chip's digital certificate private key, which is stored in encrypted form within the root certificate and cannot be accessed by others or other devices, further preventing the possibility of the "anti-counterfeiting mark" being copied.

[0058] Furthermore, before step 1, the method further includes:

[0059] When the product or its packaging is removed, the removal action triggers the energy collection module on the product to collect energy and power on the security chip;

[0060] The disassembly action triggers the anti-disassembly module on the product to generate a disassembly signal, and the disassembly signal is fed back to the security chip;

[0061] The security chip receives the disassembly signal and updates the anti-disassembly identification bit from a normal state to an abnormal state, wherein the normal state indicates that the commodity or the commodity packaging has not been disassembled, and the abnormal state indicates that the commodity or the commodity packaging has been disassembled.

[0062] Preferably, the anti-tampering identification bit in a normal state may be "0", and the anti-tampering identification bit in an abnormal state may be "1", but is not limited thereto.

[0063] Furthermore, the security chip has a built-in root key, which is used to encrypt the anti-tampering flag. This improves the security of the anti-tampering flag, further prevents illegal counterfeiting of the product, and enhances the product's anti-counterfeiting capabilities. When reading the built-in anti-tampering flag in step 2, the anti-tampering flag ciphertext is read and decrypted using the root key of the security chip to obtain the anti-tampering flag plaintext. The anti-tampering flag plaintext is read to determine whether the anti-tampering flag plaintext is in a normal state.

[0064] It is understandable that in some scenarios, the above steps 1 to 4 can also exist independently. If the anti-tampering identification bit is in a normal state, the electronic ink screen will successfully display the corresponding identification code. Even if the user does not carry a mobile terminal, it can be preliminarily determined that the product is a non-tamperable product, further simplifying the product compliance judgment process and improving the shopping experience.

[0065] Furthermore, the above step 4 specifically includes:

[0066] The security chip generates a random number and obtains current first time information;

[0067] Signing the random number and the first time information using the digital certificate private key of the security chip to generate signature information;

[0068] Obtain the serial number of the security chip, package the serial number and the signature information into verification information, encrypt the verification information using the digital certificate public key of the verification server, obtain the verification information ciphertext, and present the verification information ciphertext on the electronic ink screen in the form of an identification code.

[0069] It can be understood that the security chip is pre-installed with the digital certificate public key information of the verification server.

[0070] Furthermore, the above step 6 specifically includes:

[0071] The verification server uses its own digital certificate private key to decrypt the verification information ciphertext to obtain the serial number and the signature information;

[0072] The verification server searches the device library for the digital certificate public key corresponding to the security chip based on the serial number;

[0073] Verifying the signature using the digital certificate public key of the security chip;

[0074] After the signature verification is passed, the current second time information is obtained, and the time difference between the second time information and the first time information is calculated;

[0075] It is determined whether the time difference is greater than a preset threshold. If so, the product is determined to be a counterfeit product; if not, the product is determined to be a non-counterfeit product.

[0076] Due to the large number of security chips, the verification server searches for the corresponding security chip's digital certificate public key based on the received serial number, and then verifies the signature using the found digital certificate public key. To further prevent replay attacks, the present invention adds time information to the signature information and verifies the real-time nature of the verification information by determining whether the time difference between the sender and receiver exceeds a preset threshold, effectively preventing the risk of replay attacks by others copying the same signature information.

[0077] Furthermore, the identification code is preferably a QR code or a barcode, but is not limited thereto.

[0078] Figure 2 A block diagram of a counterfeit goods identification system according to the present invention is shown.

[0079] like Figure 2 As shown, the second aspect of the present invention further proposes a counterfeit goods identification system, comprising: an anti-counterfeiting identification device, a mobile terminal and a verification server; the mobile terminal and the verification server perform remote network communication; the anti-counterfeiting identification device comprises: an energy harvesting module, a security chip and an electronic ink screen;

[0080] The energy collection module collects energy based on mechanical action and supplies the collected energy to other modules of the anti-counterfeiting identification device in the form of electrical energy;

[0081] The security chip is used to receive the electric energy supplied by the energy collection module, power on, and read the built-in anti-tampering identification bit to determine whether the anti-tampering identification bit is in a normal state; and is also used to generate a random number when it is determined that the anti-tampering identification bit is in a normal state, and use the built-in digital certificate private key to sign the random number to generate signature information;

[0082] The electronic ink screen is used to receive the signature information from the security chip and display it in the form of an identification code;

[0083] The mobile terminal is used to scan the identification code presented by the electronic ink screen to obtain signature information, and transfer the signature information to the verification server via the network;

[0084] The verification server verifies the signature information using the digital certificate public key of the security chip, and feeds back the verification result to the user's mobile terminal for secondary anti-counterfeiting verification.

[0085] Furthermore, the anti-counterfeiting identification device also includes an anti-dismantling module; when the product or the product packaging is disassembled, the disassembly action triggers the anti-dismantling module to generate a disassembly signal, and feeds back the disassembly signal to the security chip; after receiving the disassembly signal, the security chip updates the anti-dismantling identification position from a normal state to an abnormal state, where the normal state indicates that the product or the product packaging has not been disassembled, and the abnormal state indicates that the product or the product packaging has been disassembled.

[0086] Furthermore, the identification code is preferably a QR code or a barcode, but is not limited thereto.

[0087] The identification method of the present invention can be applied to a variety of scenarios. For example, if the user does not carry a mobile terminal, the product can be verified based on whether the electronic ink screen can successfully display the identification code, which improves the convenience of identifying counterfeit goods and expands the scope of application of product anti-counterfeiting. Of course, users can also use mobile terminals to scan the identification code and use cloud-based verification servers for advanced verification. This dual verification method can improve the accuracy of counterfeit product identification, further enhance the anti-counterfeiting capabilities of legitimate products, and reduce the risk of legitimate products being counterfeited.

[0088] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
