Guangdong Laser Marking Company Applies for Anti-Counterfeiting QR Code Patent Based on Elliptic Curve Digital Signature, Enhancing Product Traceability and Security

A report on September 30, 2024, by FinanceWorld revealed that Guangdong Laser Marking Information Technology Co., Ltd. recently applied for a patent titled "A method for generating and verifying anti-counterfeiting QR codes based on elliptic curve digital signature," with publication number CN118709713A and application date in June 2024. The core of this patented technology lies in utilizing elliptic curve cryptography and blockchain technology to build a secure and reliable product anti-counterfeiting and traceability system, offering more effective solutions for high-end luxury goods, medical devices, and food safety.

The patent abstract details the specific steps of the anti-counterfeiting QR code generation and verification method. First, the system encrypts the product's unique serial number and uses the Elliptic Curve Digital Signature Algorithm (ECDSA) to generate a digital signature. The encrypted data and digital signature are then embedded into the QR code. To ensure long-term security and immutability, the generated QR code data is stored on the blockchain, ultimately forming an anti-counterfeiting QR code.

Verification is conducted via the blockchain. Users can scan the QR code, retrieve the embedded data, and verify it using the blockchain's properties. Due to the decentralization and immutability of the blockchain, this verification process ensures data authenticity and integrity, effectively preventing forgery and tampering. If the QR code data matches the data stored on the blockchain, the product's authenticity is confirmed; otherwise, the product may be problematic.

The innovative aspects of this patented technology lie in its multiple security safeguards. First, the application of elliptic curve cryptography enhances data encryption strength, making it difficult for unauthorized individuals to crack the encrypted data and obtain key information such as the product serial number. Second, the use of ECDSA ensures both data integrity and authenticity. Any modification to the QR code data will invalidate the signature, thus being identified by the system as a counterfeit product. Finally, the application of blockchain technology further enhances the system's security and reliability. The decentralized and immutable nature of the blockchain makes it difficult for attackers to tamper with data, providing strong protection for product traceability.

Compared to traditional anti-counterfeiting technologies, this anti-counterfeiting QR code technology based on elliptic curve digital signature and blockchain has significant advantages. Traditional anti-counterfeiting techniques, such as laser anti-counterfeiting and watermark anti-counterfeiting, are easily replicated or forged. This new technology utilizes the high security of elliptic curve cryptography and blockchain technology, significantly increasing the difficulty of counterfeiting. Simultaneously, using the blockchain for data storage and verification enables the full lifecycle traceability of products, providing consumers with more transparent and reliable product information.

This patented technology is applicable to multiple fields, particularly having significant application value in high-end luxury goods, medical devices, and food safety. For high-end luxury goods, anti-counterfeiting and traceability are crucial for protecting brand reputation and consumer rights. This technology can effectively prevent counterfeit products and maintain brand image. In the medical device field, product authenticity and safety are paramount. This technology can help regulatory authorities and consumers quickly identify counterfeit medical devices, safeguarding public health and safety. In food safety, this technology can effectively trace the origin, production process, and circulation of food, ensuring food safety and protecting consumer rights.

Furthermore, this technology can be integrated with IoT devices to achieve real-time monitoring and data updates. By connecting the QR code with IoT sensors, the product's status and environmental information, such as temperature and humidity, can be monitored in real time, further improving product safety and reliability. This real-time data can also be stored on the blockchain, providing more comprehensive information for product traceability. This allows companies to better understand the status of their products throughout their lifecycle and take timely measures to address potential problems.

In summary, the patent application by Guangdong Laser Marking Information Technology Co., Ltd. for the anti-counterfeiting QR code generation and verification method based on elliptic curve digital signature represents a significant breakthrough in anti-counterfeiting technology. It combines the advantages of elliptic curve cryptography, ECDSA, and blockchain technology, providing a more secure, reliable, and effective solution for product anti-counterfeiting and traceability. The application of this technology will help improve security in multiple fields, protect consumer rights, and promote healthy industry development. In the future, with continuous technological development and expanding application scenarios, this technology is expected to play a significant role in more fields, contributing to socio-economic development. The successful application of this patent also highlights Guangdong Laser Marking Information Technology Co., Ltd.'s strength in technological innovation, laying a solid foundation for its future development. This technology is expected to bring more secure and reliable products to the market and drive the development of anti-counterfeiting technology to a higher level. Data verification through the blockchain ensures data transparency and traceability, further enhancing system security. This technology not only effectively combats counterfeit products but also provides consumers with more reliable product information, enhancing consumer confidence. This technology has broad application prospects and is expected to be applied in more fields in the future, bringing greater social and economic benefits.
