Description

Technical Field

[0001] This invention belongs to the field of anti-counterfeiting identification technology, specifically relating to an NFC-based intelligent anti-counterfeiting and traceability system. Background Technology

[0002] With the rapid development of my country's economy, people's consumption levels have also risen significantly. However, along with economic development, the quality and safety of goods have become increasingly prominent issues. Unscrupulous individuals exploit loopholes in existing product authentication systems to counterfeit goods and sell them to consumers, harming their interests. To address the challenges posed by the current counterfeit goods problem, solutions for anti-counterfeiting and traceability using modern information technology are constantly being proposed, such as one-dimensional barcode technology and two-dimensional barcode technology. One-dimensional barcodes and two-dimensional barcodes have a relatively wide range of applications due to the widespread use of the internet and smartphones. However, because they can only store static information and are easily counterfeited, they cannot guarantee the accuracy of anti-counterfeiting and traceability.

[0003] NFC technology evolved from RFID technology. While RFID's transmission range extends from a few meters to tens of meters, NFC employs unique signal attenuation technology, giving it advantages over RFID in terms of shorter range, higher bandwidth, and lower power consumption. NFC provides a simple solution, allowing consumers to access, query, and receive information more intuitively. Compared to QR codes, QR codes offer less effective anti-counterfeiting and are easily damaged, but they are low-cost and easy to use, primarily applicable to low-end consumer scenarios. NFC, combining the advantages of both QR codes and RFID, can be applied to high-end consumer scenarios and is poised to become the mainstay of the future anti-counterfeiting market.

[0004] Therefore, it is necessary to propose an NFC-based intelligent anti-counterfeiting and traceability system to improve the product traceability system, ensure product quality and safety, and protect consumers' interests.

[0005] The information disclosed above in this background section is only for enhancing the understanding of the background section of this invention, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide an NFC-based intelligent anti-counterfeiting and traceability system to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An NFC-based intelligent anti-counterfeiting and traceability system includes: a system management module, an enterprise management module, a product management module, a logistics management module, and a traceability management module. The system management module is used to manage and operate the identity and permission information of system participants. The enterprise management module is used to manage partner enterprises and provide them with management permissions. The product management module is used to query, verify, add, and delete products and packaging. The logistics management module is used to query, verify, add, and delete warehousing and transportation tasks. The traceability management module is used to manage the traceability information of products and to manage information anti-counterfeiting and encryption.

[0009] Preferably, in the system management module, participants are categorized based on their attribute information and participation in anti-counterfeiting label operations. Based on this categorization, each type of user is granted the corresponding system operation permissions. Simultaneously, homomorphic encryption is used to encrypt user information.

[0010] Preferably, in the enterprise management module, a tree-structured enterprise management form is constructed, and concurrency control is used to ensure data consistency and integrity. Load balancing technology is used to evenly distribute enterprise user requests to different servers to avoid single points of failure and improve the system's concurrent processing capabilities.

[0011] Based on actual needs, pessimistic concurrency control is applied to tree-structured enterprise management, and real-time data caching is used to support concurrent data access and sharing. At the same time, dedicated hardware is used for load balancing, which can distribute requests to backend servers and their corresponding servers according to pre-defined rules.

[0012] Preferably, in the product management module, company employees use software to scan anti-counterfeiting labels to complete the binding of one item to one code. Hybrid encryption is used to bind label information and product information on the backend server. A label association mode is established based on the many-to-one relationship between products and boxes to speed up the input and verification process.

[0013] The binding process between label information and product information is achieved using a combination of RSA and 3DES algorithms. Specifically, the 3DES algorithm is used to encrypt and decrypt the anti-counterfeiting label and product information, while the RSA algorithm is used to encrypt the 3DES encryption key. When a user reads the information on the anti-counterfeiting label, the general process is as follows:

[0014] 1. When a mobile phone with NFC function is brought close to the anti-counterfeiting label, the label sends access ciphertext to the backend server. The access ciphertext is obtained by encrypting the session key and UID with the system public key. Therefore, the backend server can use its corresponding private key to decrypt the access ciphertext and obtain the session key and UID.

[0015] 2. The backend server then uses the session key to encrypt the tag's UID to obtain ciphertext, which is then sent to the anti-counterfeiting tag;

[0016] 3. After receiving the ciphertext, the tag encrypts its own stored UID with the session key and compares it with the received ciphertext. If they are equal, the authentication is successful and the next authentication step is performed.

[0017] 4. The tag encrypts the product information in the tag with a session key and encrypts the digital signature of the electronic chip with the user's private key before sending it to the backend server;

[0018] 5. The backend server then uses the session key to decrypt the received ciphertext to obtain the product plaintext information and hashes it. It then uses the system public key to decrypt the signature and compares it with the hash value of the product plaintext information. If they are equal, it means that the user has been authorized by the system, and the traceability information results are displayed.

[0019] Preferably, in the product management module, fragile label technology is used to make the anti-counterfeiting labels impossible to peel off and use. An embedded label file structure is designed according to the needs of enterprise users, and enterprises are isolated from each other, so that they cannot obtain any system data from each other.

[0020] Preferably, in the logistics management module, the Redis system is used to handle task status updates and data management, thereby improving the system's response speed and fault tolerance. In the traceability management module, an online mode that works in a network environment and an offline mode that works in a non-network environment are established to meet customer needs.

[0021] The workflow under the offline model is as follows:

[0022] (1) The user touches the anti-counterfeiting label to establish an NFC connection;

[0023] (2) The client and the tag exchange authentication public keys α and β using the DH algorithm;

[0024] (3) The client calculates the authentication key K based on the authentication public key α read from the tag;

[0025] (4) The client generates a random number R and transmits it to the anti-counterfeiting label;

[0026] (5) The anti-counterfeiting label calculates the same authentication key K based on the public key β obtained from the client, and uses the key to perform 3DES symmetric encryption on the obtained random number R to obtain the ciphertext ω;

[0027] (6) The client reads the ciphertext ω from the tag and decrypts it using the key K. If the random number R can be recovered, the authentication is successful; if the random number R cannot be recovered, the authentication fails.

[0028] (7) Display the authenticity information on the client page.

[0029] Furthermore, the system also includes an information display module, an underlying communication module, and a statistical analysis module. The underlying communication module is responsible for establishing a communication connection with the client and conducting encrypted communication. The statistical analysis module helps system users complete business statistics and data analysis and generate business reports. The information display module displays real-time data information, including business reports, to system users in a visual manner.

[0030] Preferably, the underlying communication module uses multi-threading to ensure the server responds to requests quickly, and the information display module provides an adapted information display interface for enterprise users according to the needs of different enterprises.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] This invention utilizes NFC technology for anti-counterfeiting labels. Through a hybrid encryption method, it prevents counterfeiters from tampering with the labels to counterfeit goods. It also employs fragile label technology to prevent unscrupulous merchants from transferring and using the anti-counterfeiting labels. This invention offers high security and relatively low deployment costs, effectively combating counterfeit and substandard products, enhancing user trust, and protecting corporate image. Consumers can easily verify the authenticity of goods and access traceability information using their NFC-enabled mobile phones. The process is simple and fast.

[0033] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the invention will become readily apparent from the accompanying drawings and the following detailed description. Attached Figure Description

[0034] Figure 1 This is a framework diagram of the intelligent anti-counterfeiting and traceability system of the present invention. Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example:

[0037] Please see Figure 1As shown, an NFC-based intelligent anti-counterfeiting and traceability system includes: a system management module, an enterprise management module, a product management module, a logistics management module, and a traceability management module. The system management module is used to manage and operate the identity and permission information of system participants; the enterprise management module is used to manage partner enterprises and provide them with management permissions; the product management module is used to query, verify, add, and delete products and packaging; the logistics management module is used to query, verify, add, and delete tasks related to warehousing and transportation; and the traceability management module is used to manage product traceability information and implement anti-counterfeiting and encryption management.

[0038] In the system management module, participants are categorized based on their attribute information and participation in anti-counterfeiting label operations. Based on this categorization, each type of user is assigned system operation permissions, and user information is encrypted using homomorphic encryption.

[0039] System administrators and consumers are users of the system. Enterprise personnel (including managers and employees), distributors, and warehousing and transportation personnel are users of the enterprise. At the same time, system administrators are providers of anti-counterfeiting labels. Enterprise personnel, distributors, and warehousing and transportation personnel are all users, but their respective levels of participation are different. Distributors, warehousing and transportation personnel, and consumers are traceability parties, but their respective levels of participation are different.

[0040] In the enterprise management module, a tree-structured enterprise management approach is constructed, and concurrency control is used to ensure data consistency and integrity. Load balancing technology is used to evenly distribute enterprise user requests to different servers to avoid single points of failure and improve the system's concurrent processing capabilities.

[0041] In the product management module, company employees use software to scan anti-counterfeiting labels to complete the binding of one item to one code. Hybrid encryption is used to bind label information and product information on the backend server. A label association mode is established based on the many-to-one relationship between products and boxes to speed up the input and verification process. Fragile label technology is used to ensure that the anti-counterfeiting labels cannot be peeled off and used. An embedded label file structure is designed according to the needs of enterprise users, and enterprises are isolated from each other, so that they cannot obtain any system data from each other.

[0042] The embedded tag file structure consists of a UID storage area, a system parameter area, a ciphertext area, a traceability area, a location information area, and a reserved area. It includes essential basic content, common file content, and unique file content. The essential basic content is used for tag identification, encryption and decryption operations, and location update information. The common file content includes basic product information, warehousing and distribution information, and distributor distribution information. The unique file content includes product supervision information, product-specific information, cargo box-specific information, and other information that requires special labeling.

[0043] In the logistics management module, the Redis system is used to handle task status updates and data management, improving the system's response speed and fault tolerance. In the traceability management module, an online mode that works in a network environment and an offline mode that works in a non-network environment are established to meet customer needs.

[0044] Task Management: Task objects have five states. When a task is added, its state is initialized. When it is executed, it will change to outbound, loading, unloading and inbound in sequence. Enterprise users can add, delete, modify and query tasks in all states within the enterprise.

[0045] Traceability Information Management: System personnel can query the traceability information of all products under all enterprises. Enterprise users with traceability information management permissions can add, delete, modify and query the traceability information of all products within the enterprise. When performing tasks, enterprise users will enter the traceability information of task nodes into the system.

[0046] Furthermore, the system also includes: an information display module, an underlying communication module, and a statistical analysis module. The underlying communication module is responsible for establishing communication connections with the client and conducting encrypted communication. The statistical analysis module helps system users complete business statistics and data analysis, and generate business reports. The information display module displays real-time data information, including business reports, to system users in a visual manner. The underlying communication module uses multi-threading to ensure the server's response speed to requests. The information display module provides customized information display interfaces for enterprise users according to the needs of different enterprises.

[0047] The system can call third-party interfaces to perform SMS registration. Before modifying account information, it is necessary to obtain mobile SMS verification through third-party interfaces. When creating a new address and entering traceability information, users can obtain geographical location information, such as longitude, latitude, and detailed address information, through third-party interfaces.

[0048] As can be seen from the above, the anti-counterfeiting label of this invention utilizes NFC technology and employs a hybrid encryption method to prevent counterfeiters from tampering with the label to counterfeit the product. The application of fragile label technology prevents the anti-counterfeiting label from being transferred and used by illegal merchants. It has high security and relatively low deployment costs, effectively combats counterfeit and shoddy products, enhances user trust, and protects corporate image. Consumers can use NFC-enabled mobile phones to check the authenticity of products and trace their origin information. The operation is simple and fast.
