State Grid Hebei Electric Power Company Applies for Patent on "Cloud-Chain Combined Privacy Protection Method" to Secure Electronic Archive Data

On January 22, 2025, the State Intellectual Property Office of China announced that State Grid Hebei Electric Power Company Limited had applied for a patent titled "Cloud-Chain Combined Privacy Protection Method for Electronic Archive Data," with publication number CN119272317A and an application date of August 2024. This patent aims to address security and privacy concerns surrounding the sharing and utilization of electronic archive data, offering a novel technological solution for secure data management.

The core of this patented method lies in the integration of cloud computing and blockchain technologies to construct a secure and reliable electronic archive data management platform. The patent abstract details the specific steps:

First, the system establishes separate electronic archive acquisition and cloud-chain ends. The acquisition end identifies collected electronic archive data and obtains the identification results, which are then transmitted to the cloud-chain end.

At the cloud-chain end, the identification results are published via a blockchain consensus mechanism. The decentralized and tamper-proof nature of blockchain ensures data authenticity and integrity. Simultaneously, the cloud-chain end records timestamps of the consensus parties and stores these timestamped blockchain consensus contents, providing a basis for data traceability and auditing.

To further enhance data security, the cloud-chain end implements role-based access control for consensus parties. This means different participants have different permissions, allowing access only to data consistent with their roles. Consensus parties perform blockchain consensus privacy operations based on the assigned permissions, effectively preventing data leakage and unauthorized access.

This cloud-chain integration effectively safeguards the security and privacy of electronic archive data. Cloud computing provides powerful data storage and processing capabilities, facilitating data sharing and utilization. Blockchain technology ensures data immutability and traceability, preventing data tampering or leakage. Crucially, the access control mechanism further strengthens security by restricting access to authorized users only.

This patented technology will significantly impact electronic archive management. It enhances data security and reliability, reduces management costs, and improves efficiency. For companies like State Grid Hebei Electric Power Company, which handle vast amounts of electronic archive data, this technology is highly significant.
