Description

Technical Field

[0001] The present invention relates to the technical field of anti-counterfeiting and tracing technology, and in particular to a wine anti-counterfeiting and tracing method based on flash technology. Background Art

[0002] In the field of anti-counterfeiting technology, traditional wine anti-counterfeiting methods often rely on physical labels, chemical inks or barcodes. Although these methods can play an anti-counterfeiting role to a certain extent, they have defects such as easy to imitate, difficult to track and low verification efficiency. With the development of science and technology, people have begun to seek more efficient and safe anti-counterfeiting technologies. As an emerging anti-counterfeiting method, photon fingerprint technology is widely used in the anti-counterfeiting field due to its unique optical structure and difficult-to-copy characteristics. However, photon fingerprint technology itself also has certain limitations. For example, it is difficult to update and track in real time during the circulation of products, and it is impossible to effectively distinguish whether the product has been used when the physical label is peeled off or damaged. Summary of the invention

[0003] Technical issues solved In view of the shortcomings of the prior art, the present invention provides a wine anti-counterfeiting and traceability method based on flash information technology, which solves the problem that the existing anti-counterfeiting technology cannot update and track product circulation in real time.

[0004] Technical Solution

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a wine anti-counterfeiting and traceability method based on flash information technology, comprising: S1. Make a photon fingerprint tag and embed a flash code that changes synchronously with the reading of the photon fingerprint tag. The two are dynamically mapped through a mathematical model so that the flash code reflects each reading of the photon fingerprint tag in real time; S2. Develop a flash reader with an optical imaging unit and a data processing unit. The optical imaging unit is used to capture the image of the photon tag; the data processing unit is used to extract the characteristic information of the photon fingerprint tag; S3. When the photon fingerprint tag is read, the reader sends the read data to the server via flash message, so that the flash message code corresponding to the photon fingerprint tag changes. By checking the corresponding flash message code, the circulation times can be traced and whether the flash message code has been activated can be verified, thereby providing an instant status feedback; S4. When the photon fingerprint tag is peeled off, the pattern of the photon fingerprint tag will be destroyed, and a termination signal will be immediately sent to the server. The termination signal enables the server to immediately mark the flash code corresponding to the photon fingerprint tag as activated, and the flash code will no longer change. The flash reader distinguishes whether the product is used by the state of the photon fingerprint tag; S5. The flash reader encrypts the extracted photon fingerprint feature information and the flash code and transmits it to the server; the server verifies the authenticity of the photon fingerprint tag and the flash code according to the matching result; S6. Bind each photon fingerprint tag with the flash code and store it in the server database.

[0006] A photon fingerprint label is a label that records and reflects the unique microstructure of the surface of a wine bottle and generates a corresponding flash code. It is based on a mathematical model that dynamically maps each reading of the photon fingerprint label with the corresponding part of the flash code. When the photon fingerprint label is read, the optical imaging unit captures the pattern of the label, and the data processing unit parses the photon fingerprint feature information in the label. The photon fingerprint feature information is then input into the mathematical model, and the eigenvalues ​​are extracted through image processing technology and converted into digital form. Each eigenvalue is weighted according to its importance in anti-counterfeiting verification, and the weighted eigenvalues ​​are combined into a single value through an accumulation operation, representing the comprehensive characteristics of the photon fingerprint label. This value is then input into a nonlinear function, mapped to a high-dimensional space, and finally processed through an encrypted hash algorithm to obtain a hash value of a fixed length, namely the flash code.

[0007] Whenever the photon fingerprint tag is read, the timestamp and reading count will be sent to the server via flash message. The server will update the flash message code based on the timestamp and reading count, and replace the last few digits of the original flash message code with the time and number of readings, and record it in the database on the server; each read will cause a tiny but traceable change in the flash message code, and each change is a record of the product's circulation path.

[0008] The mathematical model extracts eigenvalues ​​from the photon fingerprint tag through image processing technology. Each eigenvalue is assigned a weight according to its importance in anti-counterfeiting verification. The weight reflects the contribution of the eigenvalue to the final anti-counterfeiting effect, expressed as w i , where i is the index of the eigenvalue; the weighted eigenvalues ​​are accumulated to form a single value, which represents the comprehensive characteristics of the photon fingerprint tag. The comprehensive eigenvalue is expressed as , where v i is the i-th eigenvalue, n is the total number of eigenvalues; the comprehensive eigenvalue S is input into a nonlinear function to map the eigenvalue to a high-dimensional space, increasing the complexity of the data. The nonlinear function is , where tanh() is the hyperbolic tangent function, a is the sum of all features, and b is the average of all feature values; the output of the nonlinear function is processed by SHA-256 to obtain a fixed-length hash value, which is the flash code, expressed as H=SHA-256(f(S)), where H is the final flash code; the flash code is of fixed length, and due to the characteristics of SHA-256, even a slight change in data will result in a significant difference in the final hash value, further enhancing the uniqueness and security of the flash code; in this way, each photon fingerprint tag is assigned a unique flash code, and it changes dynamically with each reading of the photon fingerprint tag, realizing anti-counterfeiting and traceability monitoring of the entire process of product production to consumption.

[0009] The flash reader is constructed by building a device that integrates an optical imaging unit and a data processing unit. The optical imaging unit uses optical sensors to capture the microscopic patterns of the photon fingerprint label. These patterns are digital representations of the microscopic structure of the wine bottle surface. The captured patterns are then transmitted to the data processing unit, and the characteristic information of the photon fingerprint is extracted from the pattern through an image recognition algorithm. After extraction, it is sent to the server through the flash reader; the photon fingerprint characteristic information is matched and verified according to the stored database records, thereby completing the authenticity identification of the product.

[0010] When the photon fingerprint tag is read, the flash reader captures the image of the photon fingerprint tag and extracts the photon fingerprint feature information, and sends the read data to the server in real time through the flash reader; the server triggers the change of the flash code after receiving the read data, and automatically updates the corresponding flash code according to the number of times the photon fingerprint tag is read; the specific process is that at each reading, the server records the comprehensive feature value and adds the number of readings as an incremental factor to the comprehensive feature value. This incremental factor is regarded as an additional dimension of the feature value, which is used to record the number of times the photon fingerprint tag is read; after the update The flash code is a hash value generated by adding a comprehensive feature value to an incremental factor. For example, suppose a photon fingerprint tag of a bottle of wine has three feature values, namely v1=2, v2=5 and v3=3. These feature values ​​are assigned different weights according to their importance, assuming w1=1, w2=2 and w3=1.5. The initial comprehensive feature value S=w1v1+w2v2+w3v3=16.5. The server uses this comprehensive feature value as the initial value and increases the number of reads each time, where a=v1+v2+v3=10 and b=(v1+v2+v3) / 3≈3.33 ; When reading for the first time, the output of the nonlinear function is f(S)=tanh(168.33); Assume that after processing with the SHA-256 hash algorithm, the first few digits are taken to obtain the flash code H=ABC123; When reading for the second time, the server adds 1 to the number of reads and updates the comprehensive eigenvalue; that is, S=16.5+1=17.5, and the output of the updated nonlinear function is f(S)=tanh(178.33). After processing with the SHA-256 hash algorithm, the first few digits are taken to obtain the new flash code H=XYZ789.

[0011] When the photon fingerprint tag is peeled off or damaged, the integrity of its physical structure is destroyed, triggering the activation of the built-in microcircuit. The microcircuit contains sensors and communication modules for sensing whether the photon fingerprint tag is peeled off or damaged. When the physical structure of the photon fingerprint tag is damaged, such as when the product is opened or the label is peeled off, the sensor in the microcircuit will detect this change and activate the communication module in the circuit, causing it to send a specific termination signal to the server when the structure is damaged. The specific termination signal is used to identify the state change of the photon fingerprint tag and follows the communication protocol. It contains the initial flash code of the photon fingerprint tag, so that the server can accurately identify which tag sent the signal. The sending of the signal is triggered by the damage to the physical structure of the photon fingerprint tag. When the physical structure of the tag is intact, the circuit remains closed. Once the label is peeled off or damaged, the circuit will be disconnected or a current change will occur. The built-in microcircuit is triggered to send a termination signal; after receiving the termination signal, the server executes a specific processing flow; the server marks the record of the corresponding photon fingerprint tag as activated, indicating that the flash code bound to the photon fingerprint tag will no longer be updated, and the server's database records the status of each photon fingerprint tag and its corresponding flash code, including whether it has been activated; for example, suppose the photon fingerprint tag of a bottle of wine is given an initial flash code ABC123 when it is produced. When the consumer purchases and opens the bottle of wine, the photon fingerprint label is peeled off. The built-in microcircuit detects this change and automatically sends a termination signal to the server. After receiving the signal, the server immediately marks ABC123 as activated and stops any update operation on the code; any read request for the code will be displayed as used; by real-time monitoring of the update status of the flash code, the server can determine whether the product is used.

[0012] After extracting the photon fingerprint feature information, the flash reader merges it with the flash code into a data packet, which contains the features of the photon fingerprint tag and the corresponding flash code; the flash reader uses a preset key to symmetrically encrypt the data packet, which is only known by the flash reader and the server. After the encryption is completed, the flash reader sends the encrypted data packet to the server; during the transmission process, even if the data is intercepted, the content of the data cannot be deciphered due to the existence of encryption; after receiving the encrypted data packet, the server uses the same key as the flash reader to perform a decryption operation to obtain the original photon fingerprint feature information and flash code; the server executes a verification process, first calculating the hash value of the received photon fingerprint feature information, and comparing it with the stored hash value of the photon fingerprint of the wine bottle to ensure the consistency of the photon fingerprint feature information and that it has not been tampered with; the server verifies the flash code and compares the generated flash code with the flash code stored in the server.

[0013] The server returns the verification result to the flash reader and indicates the authenticity based on the result. If the verification is successful, it means that the photon fingerprint feature information and the flash code are both valid, and the product is considered to be authentic; if the verification fails, the product is considered to be counterfeit; for example, suppose the photon fingerprint feature information of a bottle of wine is Fingerprint123, and the corresponding flash code is Code456; the flash reader merges the two information and encrypts them with the key Key789, generates an encrypted data packet and sends it to the server; the server uses the same key to decrypt the data packet to obtain Fingerprint123 and Code456; the server calculates the hash value of Fingerprint123 and compares it with the hash value stored in the database.

[0014] Beneficial Effects

[0015] The present invention provides a wine anti-counterfeiting and traceability method based on flash information technology, which has the following beneficial effects: The present invention realizes the synchronous update of the flash code each time the photon fingerprint is read by dynamically changing the photon fingerprint and the flash code, thereby improving the non-replicability and real-time performance of the anti-counterfeiting mark.

[0016] The present invention realizes the whole process monitoring of products from production to consumption by binding photon fingerprint with flash code, ensuring that every change in the circulation process can be accurately recorded and verified, and enhancing the traceability and safety of products.

[0017] The present invention triggers the termination update of the flash code when the photon fingerprint label is peeled off, thereby realizing instant identification of whether the product has been tampered with or used, and improving the intelligence of the anti-counterfeiting technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a schematic diagram of the process of the present invention. DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1:

[0021] The present invention proposes a wine anti-counterfeiting and traceability method based on flash signal technology, the core of which is to utilize the dynamic binding of photon fingerprint labels and flash signal codes, and to realize the anti-counterfeiting and traceability monitoring of the entire process of wine products from production to consumption through optical imaging, image processing, transmission and dynamic updating; this embodiment includes the production of photon fingerprint labels, the development of readers, the processing and transmission of data, the dynamic updating of flash signal codes and the process of terminal verification.

[0022] During the production phase, each bottle of wine is given a unique photon fingerprint tag; the tag records and reflects the unique microstructure of the bottle surface; the optical features of the bottle surface are collected by high-precision optical instruments, and the key parameters of these features are extracted using image processing algorithms; these features are converted into digital form and an initial flash code is generated through a mathematical model; the design of the mathematical model is based on the principle of nonlinear mapping, and through weighted processing, cumulative merging and mapping of eigenvalues, a fixed-length hash value in a high-dimensional space is finally generated; specifically, the extracted optical features are weighted to generate a comprehensive eigenvalue, which is input into the nonlinear function ; This function performs complex transformations on the data and generates irreversible flash codes in combination with the encrypted hash algorithm; for example, for a set of optical eigenvalues ​​v1, v2, v3, their weights are w1, w2, w3 respectively, and the preliminary comprehensive eigenvalues ​​can be calculated by the formula S=w1v1+w2v2+w3v3; the comprehensive eigenvalues ​​are then input into the nonlinear function f(S)=tanh(aS+b), where a and b are parameters, and finally the initial flash code is obtained by the hash algorithm, for example H=SHA-256(f(S)); the initial code of each photon fingerprint tag is stored in the anti-counterfeiting database of the server, corresponding one-to-one to the physical structure of the tag.

[0023] During the circulation and use stages, the photon fingerprint tag is identified and verified in real time by a flash reader; the flash reader integrates an optical imaging unit and a data processing unit, wherein the optical imaging unit captures the pattern of the photon fingerprint tag, and the data processing unit extracts the features of the photon fingerprint tag through image processing technology, and generates a corresponding flash code; the flash reader combines the extracted optical feature data and code into an encrypted data packet, and encrypts it through a preset symmetric encryption key; the encrypted data is transmitted to the server through flash technology to ensure that the data is not tampered with or intercepted during the transmission process; after receiving the data packet, the server decrypts it with the same key and verifies the decrypted optical feature value; the server calculates the hash value of the transmitted optical feature value and matches it with the photon fingerprint hash value of the bottle of wine stored in the database to verify whether it is consistent; in addition, the server verifies the transmitted flash code and checks whether its dynamic changes conform to the logic of optical fingerprint tag reading; for example, if the initial code is ABC123, after reading, the server will record dynamic information such as reading time and number of times, and generate an updated code XYZ789.

[0024] The reading of the photon fingerprint tag will trigger the real-time update of the flash code; the server will make small but traceable dynamic adjustments to the flash code based on the number of times the tag is read and the historical records of the circulation path; specifically, the timestamp and number of reads for each read are added as incremental factors to the generation logic of the flash code; for example, for the initial comprehensive eigenvalue S=16.5, when read for the first time, the encoding calculation process will add the number of reads increment n1=1, and obtain the updated eigenvalue S′=S+n1=17.5; the output result of the nonlinear function is f(S′)=tanh(17.5), which is processed by the hash algorithm to generate a new flash code; each read will cause a small but verifiable change in the flash code, which records the circulation process of the product and provides a complete digital footprint for the full process traceability of the product.

[0025] When the product is in use, the status changes of the photon fingerprint tag are monitored in real time by the server; when the tag is peeled off or physically damaged, its unique optical characteristics will change, and the built-in microcircuit will send a termination signal to the server; after receiving the signal, the server will mark the corresponding photon fingerprint tag as activated and stop updating the flash code of the tag; for example, the photon fingerprint tag of a bottle of wine is assigned the code DEF456 during production; when the consumer peels off the label, the server receives the peeling signal, automatically marks the photon fingerprint tag as invalid, and updates the status information stored in the database to prevent counterfeiting and reuse.

[0026] The entire anti-counterfeiting and traceability process significantly improves the security and reliability of the system through the dynamic characteristics of the photon fingerprint label and the real-time interaction of the server; for example, in the circulation link, each time the photon fingerprint label of the wine bottle is read, the server will update the label's circulation record and the corresponding flash code; if the flash code verified at a certain time does not match the server record, the server will immediately prompt the potential anti-counterfeiting risk; after the consumer purchases, the authenticity information of the product and its complete circulation history can be directly obtained by scanning the label with a flash reader; if the product has been used or tampered with, the reader will prompt that the label is invalid or has been used, and the consumer can decide whether to purchase it based on this.

[0027] Through this dynamic update and real-time verification mechanism, the present invention realizes security monitoring of the entire process from production to consumption; the combination of photon fingerprint and flash coding utilizes the uniqueness of optical characteristics and the irreversibility of encryption algorithms, improves the technical threshold of product anti-counterfeiting, and realizes full-process traceability of products through digital records of the circulation process.

[0028] Embodiment 2:

[0029] Suppose that in the supply chain of a high-end wine brand, the wine anti-counterfeiting and traceability method of the present invention is applied to the entire process from product production to consumer purchase; first, in the production stage of the wine bottle, each bottle will be assigned a photon fingerprint label; the label collects the unique microstructure of the wine bottle surface through optical equipment, such as the texture, scale or other features on the glass surface that cannot be distinguished by the naked eye; the collected optical data is converted into digital information in real time, and the characteristic values ​​are extracted through the image processing algorithm, and these characteristic values ​​represent the unique identity of the wine bottle; for example, the optical characteristics of the texture on the surface of the wine bottle may generate three key values ​​v1=0.345, v2=0.876, and v3=0.561; these values ​​are calculated by weight distribution to obtain a comprehensive characteristic value S=w1v1+w2v2+w3v3=1.978, and are input into the mathematical model for processing to generate an initial flash code, such as ABC123; this code is bound to the photon fingerprint label and stored in the database of the server.

[0030] When the wine bottle enters the logistics link, the distributor will scan the photon fingerprint tag through a dedicated flash reader to verify the authenticity of the product and record the circulation information; the flash reader captures the pattern of the photon fingerprint tag through its optical imaging unit, transmits the pattern information to the data processing unit, and re-extracts the label feature value according to the same image processing algorithm; the flash reader calculates the hash value of the feature value and generates a real-time flash code. For example, at this time, according to the number of reads n1=1, the code is updated to DEF789; the flash code combines the change in the number of reads to ensure the uniqueness and traceability of each reading operation; the flash reader encrypts the code and feature information, and transmits it to the server through a symmetric key. The server decrypts and verifies the consistency of the data; if the verification is successful, the server will record the time, location and participating distributor information of this reading, and update the circulation process of the wine bottle.

[0031] During the logistics process, if the photon fingerprint tag is damaged or maliciously tampered with, the server will immediately detect the abnormality; for example, if the reading result of a certain link is inconsistent with the hash value of the original photon fingerprint, or the reading time does not match the logic of the coding change, the server will automatically issue an alarm. If the label is peeled off, the physical structure of the label will trigger its built-in circuit to send a termination signal to the server. After receiving the signal, the server marks the label as activated, stops updating its flash code, and records it as an abnormal operation in the database to prevent the bottle of wine from entering the next circulation link.

[0032] When the product arrives at the retail terminal, the consumer uses a flash reader or a matching application on the mobile phone to scan the photon fingerprint label to verify its authenticity; when the consumer scans the code, the optical imaging unit captures the texture information of the label and extracts key feature values, which are encrypted and sent to the server. The server decrypts and matches the extracted information with the data stored in the database; if the photon fingerprint feature value of the scan result is consistent with the record in the database, and the flash code conforms to the update logic, for example, it dynamically changes from ABC123 to DEF789, the consumer will receive a genuine reminder; at the same time, the circulation record of the bottle of wine can also be viewed, including the time and location of each distribution node, to ensure that the product has not gone through informal channels.

[0033] Suppose a consumer buys a bottle of high-end red wine. When scanning the code for verification, he finds that the label flash code is ABC123, but the latest code recorded on the server should be ABC124. This means that the label has been copied or tampered with. It is marked immediately and the consumer is prompted to purchase with caution. In addition, if the consumer finds that the flash code has stopped updating when scanning and the server shows that the label status is activated, it means that the bottle of wine has been opened or counterfeited. Through this dynamic coding verification mechanism, not only can the authenticity of the product be intuitively judged, but also the traceability information of the entire process can be obtained, further enhancing purchasing confidence.

[0034] The present invention effectively solves the problems existing in traditional anti-counterfeiting methods, such as difficulty in dynamic tracking and easy copying of labels, and improves the safety and credibility of products in circulation.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
