Guangzhou Power Supply Bureau of Guangdong Power Grid Applies for a Blockchain-Based Power Data Traceability System Patent: An Innovative Attempt to Enhance Power Data Security

On January 16, 2025, the State Intellectual Property Office of China revealed that Guangzhou Power Supply Bureau of Guangdong Power Grid Company Limited (hereinafter referred to as "Guangzhou Power Supply Bureau") applied for a patent titled "Blockchain-based power data traceability system and power data processing method," with publication number CN119299150A and application date in September 2024. This patent application marks a significant step for Guangzhou Power Supply Bureau in leveraging blockchain technology to enhance power data security, offering new ideas and solutions for data security management in the power industry.

The patent abstract indicates that the patent involves a blockchain-based power data traceability system, power data processing method, power data traceability method, device, computer equipment, computer-readable storage medium, and computer program product. This demonstrates that Guangzhou Power Supply Bureau's patent application encompasses not only the system architecture design but also a complete solution including data processing, traceability methods, and related hardware and software. This comprehensive patent application reflects Guangzhou Power Supply Bureau's in-depth research and complete technological layout of this technology.

The system's main components include blockchain nodes, data traceability parties, and multiple cryptographic proxy nodes authorized by the blockchain nodes. These components work together to form a secure and reliable power data traceability system. The blockchain node plays a core role, responsible for the initial encryption of received raw power data. This step ensures the initial security of the data, preventing its tampering or leakage during transmission. The encrypted data is not directly stored in the blockchain node but undergoes a series of encryption processes.

Specifically, the blockchain node uses its locally stored key to initially encrypt the raw power data, obtaining the initial encrypted data. Subsequently, the blockchain node, based on its locally stored key and the key of the data traceability party, determines and sends a re-encryption key to the cryptographic proxy node. This complex encryption process ensures that only authorized parties can access the decrypted original data, significantly improving data security and confidentiality.

The data traceability party is responsible for sending power data traceability requests to the blockchain node. This request includes the digital signature of the data traceability party, ensuring the authenticity and integrity of the request. After identity verification, the system will perform a rich query in the blockchain through a preset smart contract, ultimately obtaining the power data traceability results. The use of smart contracts ensures the automation, transparency, and immutability of the entire traceability process, further enhancing the system's reliability and efficiency.

Through this system design, Guangzhou Power Supply Bureau aims to address the security and efficiency issues in power data traceability. Traditional power data traceability methods often face challenges such as easy data tampering, difficulty in traceability, and low efficiency. The blockchain-based traceability system, through its distributed storage, encryption algorithms, and smart contracts, effectively overcomes these issues. The distributed nature of blockchain makes data storage more secure and reliable; even if some nodes fail, the entire system will not be affected. Encryption algorithms guarantee data confidentiality, preventing unauthorized access. The automated execution of smart contracts improves traceability efficiency and reduces the risk of human intervention.

Therefore, this patent application by Guangzhou Power Supply Bureau has significant practical significance. It can not only enhance the security of the power data traceability process but also improve data management efficiency, providing a new technical means for data security management in the power industry. Against the backdrop of increasing emphasis on data security, the application prospects of this technology are very broad.
