Description

Technical Field

[0001] This scheme belongs to the field of liquor packaging anti-counterfeiting, and specifically relates to a traceable liquor packaging anti-counterfeiting method based on the Internet of Things. Background Art

[0002] Liquor packaging anti-counterfeiting is of great significance. It not only protects the rights and health and safety of consumers, but also maintains the brand image and corporate interests, and plays a key role in promoting the healthy development of the industry and fair competition. Effective anti-counterfeiting measures can improve product traceability, curb counterfeit and shoddy products, ensure food safety, maintain tax order, and promote related technological innovation. At the same time, it enhances the international competitiveness of Chinese liquor, facilitates market supervision, and improves the overall consumer experience. In short, liquor packaging anti-counterfeiting is an important means to ensure product quality, maintain market order, and promote industry development, and its significance is far-reaching and extensive.

[0003] Existing anti-counterfeiting methods for liquor packaging face multiple challenges: traditional anti-counterfeiting technology is easy to imitate, and the identification cost of advanced anti-counterfeiting means is high; the information of each brand's anti-counterfeiting system is isolated, and the traceability system is imperfect; there is a lack of unified standards in the industry, and the integration of online and offline anti-counterfeiting is not close enough; these problems have led to limited anti-counterfeiting effects and it is difficult to fully respond to the increasingly complex challenges of counterfeiting. It is urgent for the industry, enterprises and regulatory authorities to work together to adopt new technologies and improve systems to enhance the overall effectiveness of liquor packaging anti-counterfeiting. Summary of the invention

[0004] The purpose of this scheme is to provide a traceable liquor packaging anti-counterfeiting method based on the Internet of Things, in order to solve the problems of anti-counterfeiting technology being easily imitated, high cost of identifying anti-counterfeiting means, imperfect information traceability system of anti-counterfeiting system, and limited anti-counterfeiting effect caused by insufficient integration of online and offline anti-counterfeiting.

[0005] In order to achieve the above purpose, this scheme provides a traceable liquor packaging anti-counterfeiting method based on the Internet of Things, comprising the following steps: S10: a conductive film is made by randomly adding conductive materials, and then m leads are randomly drawn out of the conductive film, and the leads are connected to the RFID tag, and the RFID tag and the conductive film are fixedly connected to the packaging box of the liquor; S20: The unique identification code of the chip of the RFID tag is recorded as X. The RFID tag randomly selects n leads from the m leads through X, and generates n non-repeating numbers 1-8 as the n leads for resistance measurement. The resistance value measured by the n leads is the measurement value R of the conductive film. At the same time, an OTP chip is integrated in the RFID tag. When the packaging box is produced, R and the product information number are stored in the OTP chip. At the same time, the stored value is saved to the server through the RFID card reader when the liquor leaves the factory. S30: The user wirelessly reads the data in the RFID tag or activates the RFID tag through the RFID reader device. After the user reads the data in the RFID tag, the RFID reader device stores the data read from the RFID tag in the RFID reader and uploads it to the server. The data in the read RFID tag is then compared with the data in the server to determine whether the liquor packaging is damaged. If damaged, the measured conductive film resistance will change, and an alarm message will be issued to remind the user that there is a problem with the product. Finally, the current user information pre-stored in the RFID reader is uploaded to the server for storage.

[0006] The principle and effect of this scheme are: (1) The method of randomly adding conductive materials used in this scheme produces a conductive film with uneven resistance distribution, which makes the conductive film of this scheme unique and difficult to imitate; on this basis, this scheme uses a random method to lead out the leads on the conductive film, and the number of leads is not fixed, which further enhances the uniqueness of the conductive film, so that the resistance value R of the conductive film derived by the leads is more unique and more difficult to imitate and replicate; when the packaging box is destroyed, the conductive film fixedly connected to the packaging box is destroyed, causing R to change, and R on the server is encrypted data. A third party or user cannot simulate a conductive film with the same resistance value without knowing the true value of R.

[0007] The conductive film used in this solution also has the function of enhancing the mechanical strength of the package. Since most conductive materials are hard, the conductive film mixed with various conductive materials has the function of increasing the thickness and mechanical strength of the liquor packaging box. After increasing the thickness, the liquor packaging box can be more creative in appearance to attract customers, and after increasing the mechanical strength, it can provide stronger protection for the liquor in the packaging box, such as reducing the squeezing force and collision force on the liquor. At the same time, due to the material characteristics, the conductive film also has the effects of moisture-proof and anti-oxidation. It can not only block the external air and moisture from affecting the quality of the liquor, slow down the contact between the liquor in the package and the external oxygen, reduce the speed of the oxidation reaction, extend the shelf life of the liquor and maintain the stability of its flavor, but also effectively prevent moisture from penetrating into the package and maintain a dry environment for the liquor.

[0008] It can be seen that this solution solves the problem that anti-counterfeiting technology is easy to imitate, while also increasing the protection of liquor.

[0009] (2) The randomly added conductive materials used in this solution are of many types and cheap, which makes the production cost of the conductive film of this solution low; and the price of the RFID tags used by this party is low, which makes the production cost of the liquor packaging box with conductive film and RFID tags produced by this solution low; the RFID card reader required in the user identification process is cheap, and the RFID card reader can be used multiple times, and the use of the RFID card reader is simple, which makes the anti-counterfeiting means identification cost that users need to pay low. It can be seen that this solution solves the problem of high anti-counterfeiting means identification cost.

[0010] (3) In this solution, the product information number, factory information, user information and other related information of the liquor are stored in the server. The relevant information can be queried by logging into the server. It can be seen that this solution solves the problem of imperfect information traceability system of the anti-counterfeiting system.

[0011] (4) The RFID tag of this solution stores the product information number of the liquor and the unique identification code of the RFID tag chip X. The server stores the product information of the liquor, X and other detailed related information. During the user authentication process, the server obtains the detailed information of the liquor through the user information using X. This method not only closely combines the online and offline information of the liquor, but also closely combines the user information and X, solving the problem of insufficient integration of online and offline anti-counterfeiting, and also provides strong support for improving the information traceability system of the anti-counterfeiting system.

[0012] To sum up, this solution solves four problems: the anti-counterfeiting technology of liquor packaging anti-counterfeiting methods is easy to imitate, the cost of identifying anti-counterfeiting means is high, the information traceability system of the anti-counterfeiting system is imperfect, and the online and offline anti-counterfeiting integration is not close enough, thereby solving the problem of limited anti-counterfeiting effect of liquor packaging anti-counterfeiting methods.

[0013] Furthermore, in the step S10, the type of conductive material added to the conductive film includes one or more mixed types, the conductive material of the conductive film is unevenly distributed, m is not less than 8, and n is 4.

[0014] One or more mixed conductive materials can increase the difference between conductive films of different production batches, thereby increasing the uniqueness of the conductive film; at the same time, the conductive material of the conductive film is unevenly distributed, which increases the difference between the conductive films of the same production batch, further increasing the uniqueness of the conductive film; and, the value of m (the number of leads) is not fixed and is not less than 8, and n (the number of leads used for resistance measurement) is 4, so that R (the resistance of the conductive film) in a package is different and cannot be estimated, making R unique. This makes the anti-counterfeiting technology more difficult to be imitated.

[0015] Furthermore, in the step S20, a four-needle detection method is used when measuring R.

[0016] Due to random doping, the R of each conductive film measured is also random. The output of conductive films is large, and the four-needle detection method does not require calibration. Using the four-needle detection method when measuring R can greatly save the quality inspection time of the conductive film, thereby improving the production efficiency of the conductive film.

[0017] Further, in the step S20, the structure of the RFID tag includes a FLASH storage module, an OTP storage module, a multi-lead four-probe thin film measurement circuit, an RFID antenna, an RFID chip and a wireless power supply coil, wherein: FLASH storage module: used to store communication data; OTP storage module: One-time programmable FLASH, that is, data can only be written once; Multi-lead four-probe thin film measurement circuit: Multi-lead requires no less than 4 leads; RFID antenna: used for communication with RFID reader; RFID chip: used to handle communication with the RFID reader, circuit measurement and logic processing.

[0018] Wireless power supply coil: When the RFID card reader is working, it provides power for the RFID tag chip to work normally through wireless power supply.

[0019] The above OTP storage module can prevent the RFID tag data from being tampered with, ensuring the reliability of the data; the multi-lead requirement is no less than 4 leads, which only needs to meet the minimum requirements of the four-probe thin film measurement circuit. This method can reduce the thickness of the RFID tag as much as possible, reduce the weight of the packaging box, and avoid waste of production costs.

[0020] Furthermore, in the step S30, the RFID reader device is also used to record the current user's information in a coded form, including the merchant name, merchant address, and transaction date. The current user's information is bound to the user information in the form of a number. The current user's information needs to be added, deleted, checked, and modified after logging into the backend service of the liquor manufacturer / agent.

[0021] Recording the current user's information in a coded form makes it easier for the RFID reader to transmit user information; the binding method can reduce the storage burden of the reader; using login behavior to limit the addition, deletion, query and modification of user information can reduce the risk of user information being stolen and tampered with, while protecting user information security and strengthening the information security of the anti-counterfeiting system information traceability system.

[0022] Furthermore, when merchants import and export goods, they need to read the liquor product information through the RFID card reader and upload the liquor product information to the server.

[0023] This approach further improves the anti-counterfeiting system information traceability system.

[0024] Furthermore, the RFID reader device is composed of a communication module, a storage module, a touch display screen, a face recognition module, a fingerprint recognition module and a global positioning module, wherein: Fingerprint recognition / face recognition module: used for identity authentication; Touch screen: used to display product information and select and set traceability information; Storage module: saves identity verification personnel data and traceability information database; Communication module: used to maintain data communication with the server; Global Positioning System: Obtain the geographic location and time when tracing the product; RFID reader module: used for data communication with RFID and power supply for RFID tags.

[0025] RFID card reader devices provide a variety of identity authentication methods, giving users more choices and improving user experience. At the same time, they can also make the card reader suitable for more users. The touch screen setting is easier for users to read, making identification operations simpler and further improving user experience. The collaboration of the global positioning system and communication module provides more powerful technical support for the anti-counterfeiting system information traceability system and provides strong guarantee for the operation of the anti-counterfeiting system information traceability system.

[0026] Furthermore, after completing the corresponding traceability information and identity authentication information using the RFID card reader device, warehouse and sales personnel only need to scan the code to automatically generate the unique identity information and tracking data of the product, and send the generated data to the server.

[0027] Automatically generating unique identity information and tracking data for products can make the operations of warehouse personnel and sales personnel simpler, reduce their workload, and avoid misreporting or omission of information caused by operational errors.

[0028] Furthermore, the server is used for user registration, storage of liquor import and export data, and management, viewing, and analysis of commodity sales and recording of RFID data of all liquor.

[0029] This method makes it easier to manage various data. When the amount of stored data is too large, the server can more easily expand the storage space. At the same time, separating the storage of various data from other functional modules is more conducive to data isolation and can better protect data security.

[0030] Furthermore, the conductive film is prevented from being fixedly adhered to the inside of the packaging box, and the RFID antenna is placed between the paper packaging and the conductive film.

[0031] This method can not only protect the RFID antenna from being damaged, but also take into account the aesthetics of the packaging box. It can also make the conductive film more susceptible to the impact of the packaging box, and will be damaged along with the packaging box when the packaging box is damaged, making the anti-counterfeiting technology difficult to be imitated.

[0039] The following will clearly and completely describe the concept and technical effects of the present invention in combination with the embodiments, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention: The embodiment is basically as shown in the attached Figure 1-6 As shown: A traceable liquor packaging anti-counterfeiting method based on the Internet of Things comprises the following steps: S10: A conductive film is made by randomly adding conductive materials, and then m leads 5 are randomly drawn out of the conductive film, as shown in the attached figure. Figure 6 As shown, these leads 5 are connected to the RFID tag 4, and the RFID tag 4 and the conductive film are fixedly connected inside the packaging box of the liquor.

[0040] When the conductive film is processed, it is necessary to randomly add conductive material (ie, conductive fiber 1) to the conductive film material. The conductive fiber 1 can be made of very fine conductive glass fiber, copper wire or other conductive materials, etc., in order to make the resistance distribution of the processed conductive film uneven.

[0041] When adding conductive fibers 1, more uneven conductive fibers 1 are added to the conductive film corresponding to the 12 sides of the liquor packaging box, so that the conductive film provides stronger mechanical support for the liquor packaging box. For high-end liquor, precious conductive materials such as gold, silver, copper, or more colorful conductive materials can also be used as conductive fibers 1, so that the conductive film gives the liquor packaging a unique visual effect, such as metallic luster and three-dimensional sense, making the packaging more eye-catching in appearance and enhancing the attractiveness and recognition of the product. The pattern, color, and shape of the conductive film can be changed by adding conductive fibers 1 of different colors to achieve customized packaging to meet the needs and preferences of different consumers.

[0042] Then, no less than 8 leads 5 are randomly drawn out from the processed conductive film to measure the resistance of the conductive film using a four-probe detection method (the measurement method can refer to the master's thesis "Research on Thin Film Resistance Test System Based on LabVIEW by Four-probe Method - Zhang Ruqing"). Due to the random doping, the resistance of each conductive film measured is also random.

[0043] Among them, the RFID tag 4 also records the resistance ratio measured between the four measuring resistance leads 5 before the liquor leaves the factory. After leaving the factory, when the R0 (the resistance value of the conductive film measured after leaving the factory) measured by the RFID tag 4 is inconsistent with the R recorded before leaving the factory, the RFID tag reads the resistance values ​​measured by the four leads 5 respectively, and obtains the resistance ratio between the four leads 5 according to the measured resistance values, and compares the resistance ratio measured this time with the resistance ratio recorded before leaving the factory. If: the ratios are different, it is determined to be counterfeit liquor; if the ratios are the same, the difference between R0 and R is calculated, and the degree of moisture or oxidation of the liquor is inferred from the difference, and then the degree of change in the quality of the liquor is inferred, and finally the inferred quality change of the liquor is prompted to the user.

[0044] S20: The chip unique identification code of the RFID tag 4 is recorded as X. The RFID tag 4 randomly selects n leads 5 from the m leads 5 through X, and generates n non-repeating numbers 1-8 as the n resistance measurement leads 5 (the leads 5 are the resistance measurement circuit 7 of the RFID tag to measure the conductive fiber 1, that is, the resistance measurement circuit to measure the resistance value of the conductive film). The resistance value measured by the n leads 5 is the measurement value R of the conductive film. At the same time, an OTP chip is integrated in the RFID tag 4. When the packaging box is produced, R and the product information number are stored in the OTP chip. At the same time, the stored value is saved to the server through the RFID card reader when the liquor leaves the factory.

[0045] The server is used for user registration, storage of liquor import and export data, management, viewing, analysis of product sales, and recording of all liquor RFID data. The functions provided by the server can be used to trace the product source and analyze product benefits, providing favorable data support for the manufacturer's liquor production and sales. This part is a general method and will not be explained here.

[0046] Among them, the RFID tag 4 has the function of identifying the ordinary RFID tag 4, and also has the function of measuring the resistance of the conductive film, which is used to measure the resistance by randomly drawing out no less than 8 leads 5 from the conductive film. Since only 4 leads 5 are needed to measure the resistance, 4 of them need to be randomly selected to generate random resistance (the 4 leads 5 constitute the resistance measurement circuit 7). The random method is to use the unique identification code of the RFID chip, and then generate 4 non-repeating numbers from 1 to 8 as the 4 resistance measurement leads 5. The RFID also needs to integrate an OTP (one-time programmable FLASH) chip to store the measured value of the conductive film and the product information number in the OTP chip when the packaging box is produced, and save the stored value to the server through the RFID card reader when leaving the factory.

[0047] The packaging box is composed of two parts. First, the outermost part is ordinary paper packaging, and then the conductive film anti-counterfeiting material is bonded to the inner surface of the paper packaging.

[0048] Before bonding, the liquor needs to be placed in a conductive film, and then the conductive film is sealed by ultrasonic welding or heat melting welding. Then the RFID antenna is placed between the paper packaging and the conductive film to facilitate data reading by the RFID reader, and finally bonded to the paper packaging.

[0049] With this packaging form, since the paper packaging is combined with the conductive film, as long as the packaging box is damaged, the conductive film will be damaged, and eventually the resistance of the conductive film will change, thereby judging that the product has been damaged artificially and achieving the anti-counterfeiting function.

[0050] The seal pull wire 3 is connected to the paper packaging. When the paper packaging box is opened, the seal pull wire 3 is driven to be pulled open along the seal edge 2 to facilitate the user to open the box.

[0051] The structure of the RFID tag 4 includes a FLASH storage module, an OTP storage module, a multi-lead four-probe thin film measurement circuit, an RFID antenna, an RFID chip and a wireless power supply coil, such as Figure 2 As shown. Among them, FLASH storage module: used to store communication data; OTP storage module: a one-time programmable FLASH, that is, data can only be written once to ensure data reliability; Multi-lead four-probe thin film measurement circuit: Multi-lead requires no less than 4 leads 5, that is, it only needs to meet the minimum requirements of the four-probe thin film measurement circuit. Here, 8 leads 5 are mainly used as an example. RFID antenna: used for communication with RFID reader; RFID chip: used to handle communication with the RFID reader, circuit measurement and logic processing.

[0052] Wireless power supply coil: When the RFID card reader is working, it provides power for the RFID tag 4 chip to work normally through wireless power supply.

[0053] The RFID tag 4 workflow is as follows: When the RFID reader needs to read data from the RFID tag 4, the RFID tag 4 will be activated, the RFID reader will provide power, and read data from the RFID tag 4 chip. The implementation process is as follows: Figure 3 shown.

[0054] S21: Determine whether data is received, if so, go to S22, otherwise go to S29; S22: Parse the received data (including device number, time, and communication encryption key, where the communication encryption key is randomly generated by the scanning device to ensure that even if the same data is transmitted, different data will be formed after encryption to avoid brute force cracking of communication content by unauthorized devices), and determine whether the data is valid. If the data is valid, go to S23, otherwise go to S29; S23: Read the circuit resistance and the unique identification code of the RFID tag 4, and determine whether the RFID tag 4 has been used, that is, by determining whether the OTP storage module has been written with data. If the RFID tag 4 is not used, go to S24, otherwise go to S26; S24: Read the circuit resistance value, and write the scanning device number, time, and resistance value into the OTP storage module. At the same time, write the first scanning device number, time, and resistance value into the FLASH module, and then go to S25; S25: Encrypt the communication encryption key obtained by parsing in S22 to write the success result (including the success flag, the write resistance value, the write time, and the RFID unique identity code), and then go to S28; S26: Read the first code scanning device number, time, and resistance value from the OTP storage module, and read the last five code scanning device numbers, time, and measured resistance values ​​from the FLASH. If the number is less than five, read as many times as there are, and then go to S27; S27: Encrypt all the data obtained in S26 using the communication encryption key obtained by parsing in S22, and then go to S28; S28: Send the encrypted data to the scanning device through the RFID antenna, and write the current scanning device number, time, and measured resistance into FLASH, and then go to S29; S29: End the RFID tag 4 reading process.

[0055] S30: The user wirelessly reads the data in the RFID tag 4 or activates the RFID tag 4 through the RFID reader device. After the user reads the data in the RFID tag 4, the RFID reader device stores the data read in the RFID tag 4 in the RFID reader and uploads it to the server. The data read in the RFID tag 4 is then compared with the data in the server to determine whether the liquor packaging is damaged. If damaged, the measured conductive film resistance will change, and an alarm message will be issued to remind the user that there is a problem with the product. Finally, the current user information pre-stored in the RFID reader is uploaded to the server for storage.

[0056] Among them, the RFID reader device has the function of wirelessly reading the data in the RFID tag 4 and activating the RFID tag 4, and stores the read data in the RFID reader and uploads it to the server. At the same time, it is judged with the data in the server to determine whether the liquor packaging is damaged. If it is damaged, it will cause the measured conductive film resistance to change, and an alarm message will be issued to remind the user that there is a problem with the product.

[0057] The RFID reader device records the current user's information in a coded form, including the manufacturer, first-level agent, second-level agent, ..., first-level retailer, second-level retailer, etc. This information includes the merchant name, merchant address, and transaction date. This information is bound to the user information in the form of a number. If the information needs to be added, deleted, checked, or modified, it can be modified by logging into the backend service of the liquor manufacturer / agent on the computer. When the merchant is shipping goods, the liquor product information needs to be read through the RFID reader and uploaded to the server.

[0058] As attached Figure 4 As shown, the RFID reader device consists of a communication module, a storage module, a touch screen, a face recognition module, a fingerprint recognition module and a global positioning module. Among them: Fingerprint recognition / face recognition module: used for identity authentication; Touch screen display: used to display product information and select and set traceability information.

[0059] Storage module: saves identity verification personnel data and traceability information database.

[0060] Communication module: used to maintain data communication with the server; Global Positioning System: Obtain the geographic location and time when tracing the product; RFID reader module: used for data communication with the RFID and for supplying power to the RFID tag 4 .

[0061] After completing the corresponding traceability information and identity authentication information using this device, warehouse and sales personnel only need to scan the code to automatically generate the unique identity information and tracking data of the product, and send the data to the server, which can significantly improve work efficiency.

[0062] As attached Figure 5 As shown, the working process of the RFID reader device is as follows: S31: System initialization; S32: Determine whether to add a new user. If a new user needs to be added, complete the entry of face and fingerprint data according to the user's selection; S33: After completing the identity entry, enter the identity authentication process, first determine whether there is a fingerprint pressed, if there is a fingerprint pressed, read and match the fingerprint data, if the match is successful, log in to the system, otherwise determine whether there is a face, if the face match is successful, log in to the system, otherwise return to S32; S34: The RFID reader device will connect to the designated server according to the pre-configured server parameters, and then determine whether to trigger the RFID reading function. If it is triggered, it will go to S35, otherwise it will return to S32; S35: Generate a communication encryption key randomly, obtain the system time and device ID, and encrypt the system time and device ID with the generated communication encryption key, and then send the encrypted data and communication encryption key to the RFID tag 4 (the sent encrypted data and communication encryption key will be encrypted again by the encryption key fixed by the device, including the encryption and decryption process of the RFID tag 4 and the RFID reader device), and wait for the RFID to return the reading result, and go to S36; S36: Decrypt the returned data with the communication encryption key, parse the decrypted data, and determine the type of data. If the data is device activation data, construct RFID activation status data (encrypted data using the encryption algorithm to write the resistance value, writing time, and RFID unique identity code to the OTP storage module), and then go to S38, otherwise go to S37; S37: Obtain the resistance value in the OTP storage module and the resistance value read from the circuit, and determine whether the two resistance values ​​are consistent. If they are inconsistent, an alarm is triggered and the process goes to S38, otherwise, the process goes directly to S38; S38: Display the parsed data and results on the display screen, that is, display whether the resistance value is consistent or whether the RFID tag 4 is activated, and then go to S39; S39: Send the decrypted data, device number and user information to the server (this process also requires encryption).

[0063] When used specifically: The manufacturer randomly adds conductive material to the conductive film material with very fine conductive glass fiber, copper wire or other conductive materials to make a conductive film, and then randomly draws out 8 leads 5 in the processed conductive film, and then generates 4 non-repeating numbers of 1-8 through the unique identification code of the RFID chip as the 4 resistance measurement leads 5. The manufacturer first places the liquor in the conductive film, and then seals the conductive film by ultrasonic welding or heating and melting welding, and then places the RFID antenna between the paper packaging and the conductive film, and finally bonds it to the paper packaging.

[0064] The manufacturer also integrates an OTP (One-Time Programmable FLASH) chip in the RFID tag 4, stores the measured value of the conductive film and the product information number in the OTP chip, and saves the stored value to the server through the RFID card reader when leaving the factory.

[0065] After the liquor leaves the factory, the user turns on the RFID reader device before identifying the liquor. After the RFID reader device is turned on, the RFID reader completes system initialization and displays login and registration prompts. The user selects the login option, and the RFID reader displays the login interface. The user enters and account information on the login interface. After the RFID reader obtains the account information, it prompts the user to enter verification information. The user then enters the fingerprint information, and the reader obtains the fingerprint information entered by the user. The reader determines that the account information entered by the user matches the fingerprint information, and displays the system after successful login.

[0066] After the user logs in successfully, the RFID reader is brought close to the RFID tag 4. The RFID reader provides power to the RFID tag 4, the RFID tag 4 is activated, the RFID reader reads data from the RFID tag 4 chip, the RFID reader randomly generates a communication encryption key, obtains the system time and device ID, and encrypts the system time and device ID with the generated communication encryption key, and then sends the encrypted data and communication encryption key to the RFID tag 4 (the sent encrypted data and communication encryption key will be encrypted again by the encryption key fixed by the device, including the encryption and decryption process of the RFID tag 4 and the RFID reader device), and waits for the RFID to return the reading result.

[0067] After receiving the encrypted data and communication encryption key, the RFID tag 4 parses and determines whether the received encrypted data and communication encryption key are valid. The RFID tag 4 determines that the encrypted data and communication encryption key are valid, and then reads the circuit resistance and the unique identity code of the RFID tag 4, determines that the RFID tag 4 is not in use, reads the circuit resistance, and writes the scanning device number, time, and resistance value into the OTP storage module, and writes the first scanning device number, time, and resistance value into the FLASH module; then encrypts the communication encryption key obtained by the analysis to the write success result (including the success flag, write resistance value, write time, and RFID unique identity code), sends the encrypted data to the RFID reader through the RFID antenna, and writes the current scanning device number, time, and measured resistance into the FLASH, and finally ends the RFID tag 4 reading process.

[0068] The RFID reader decrypts the returned data using the communication encryption key, parses the decrypted data, determines that the data type is device activation data, and constructs RFID activation status data. It then displays the parsed data and results on the display screen, and finally sends the decrypted data, device number, and user information to the server (this process also requires encryption).

Claims

1. A traceable liquor packaging anti-counterfeiting method based on the Internet of Things, characterized in that: The following steps are involved: S10: a conductive film is made by randomly adding conductive materials, and then m leads are randomly drawn out of the conductive film, and the leads are connected to the RFID tag, and the RFID tag and the conductive film are fixedly connected inside the packaging box of the liquor; S20: The unique identification code of the chip of the RFID tag is recorded as X. The RFID tag randomly selects n leads from the m leads through X, and generates n non-repeating numbers 1-8 as the n leads for resistance measurement. The resistance value measured by the n leads is the measurement value R of the conductive film. At the same time, an OTP chip is integrated in the RFID tag. When the packaging box is produced, R and the product information number are stored in the OTP chip. At the same time, the stored value is saved to the server through the RFID card reader when the liquor leaves the factory. S30: The user wirelessly reads the data in the RFID tag or activates the RFID tag through the RFID reader device. After the user reads the data in the RFID tag, the RFID reader device stores the data read from the RFID tag in the RFID reader and uploads it to the server. The data in the read RFID tag is then compared with the data in the server to determine whether the liquor packaging is damaged. If damaged, the measured conductive film resistance will change, and an alarm message will be issued to remind the user that there is a problem with the product. Finally, the current user information pre-stored in the RFID reader is uploaded to the server for storage.
