UnionPay Applies for Carbon Account Data Management System Patent: Blockchain Technology Ensures Carbon Emission Data Security

On December 21, 2024, the State Intellectual Property Office of China revealed that China UnionPay Co., Ltd. has applied for a patent titled "A Carbon Account Data Management System, Method, Apparatus, Device, and Medium," with publication number CN119151751A and an application date of August 2024. This patent application marks a significant step for UnionPay in the carbon neutrality field and signifies the increasingly important role of financial technology in promoting green and low-carbon development.

The patent abstract indicates that the technology aims to provide a highly secure carbon account data management and carbon account ledger audit solution. It details a blockchain-based carbon account data management system capable of efficiently recording, managing, and auditing carbon emission reduction data, ensuring data integrity, authenticity, and immutability.

The system primarily comprises three core components: a carbon account management device, a blockchain management device, and an audit device. These components interact to manage the entire lifecycle of carbon account data. First, the carbon account management device creates carbon accounts and generates a first triplet containing a read hash, a write hash, and a counter based on the accumulated carbon emission reduction value. This first triplet is a crucial data unit in the system, recording the current state of the carbon account.

Subsequently, the carbon account management device sends this first triplet to the blockchain management device. The blockchain management device, acting as the system's core, leverages the immutability and distributed ledger characteristics of blockchain technology to update the triplets on the blockchain, ensuring that all carbon emission reduction data is securely and reliably recorded and stored. The application of blockchain technology effectively prevents data from being modified or deleted at a single point, enhancing data security and trustworthiness.

After a carbon account transaction, the carbon account management device obtains the transaction carbon emission reduction value from the transaction information and determines a new tripletthe second triplet. This second triplet reflects the transaction's impact on the carbon account balance. Similarly, the carbon account management device sends the second triplet to the blockchain management device, which updates the triplets on the blockchain to reflect the latest changes in the carbon account balance.

To ensure data accuracy and reliability, the system incorporates an audit mechanism. After completing a transaction, the carbon account management device sends a ledger containing the post-transaction carbon emission reduction value to the audit device. The audit device audits the ledger and determines the audit results. This ensures the authenticity and reliability of carbon account data, providing strong safeguards for carbon emission data management.

The core of this patented technology lies in its application of blockchain technology. As a distributed ledger technology, blockchain offers high security, transparency, and traceability. Its application to carbon account data management effectively prevents data tampering or loss, ensuring the authenticity and reliability of carbon emission reduction data and providing strong technical support for achieving carbon neutrality goals.

This design enables the management of the entire lifecycle of carbon account data, ensuring that all data, from carbon account creation and transaction records to final audit results, is securely and reliably recorded and managed. This technology not only improves the efficiency of carbon account data management but also effectively safeguards data security and reliability, providing technical support for building a transparent and trustworthy carbon emission management system.

As a leading domestic payment institution, UnionPay has long been committed to promoting financial technology innovation. This application for a carbon account data management system patent is a significant demonstration of its active response to the national "dual carbon" strategy and its promotion of green finance. The application of this patented technology will help improve China's carbon emission data management level and contribute to achieving carbon neutrality goals. It also showcases UnionPay's continued investment in technological innovation and green development, providing a valuable reference for other financial institutions.

This system offers significant advantages in security, utilizing the decentralized nature of blockchain to prevent single points of failure and malicious data tampering. Distributed storage and encryption technologies ensure data integrity and confidentiality, improving the reliability of carbon emission data management.

Furthermore, the system's design also considers audit requirements. The inclusion of an independent audit device for regular audits of carbon account ledgers further enhances data credibility and safeguards the healthy development of the carbon emission market.

In summary, UnionPay's application for this carbon account data management system patent represents the positive role of financial technology in addressing the challenges of climate change. It not only provides a highly efficient and secure carbon emission data management solution but also lays a solid foundation for building a transparent and trustworthy carbon trading market, providing crucial technical support for achieving China's carbon neutrality goals. In the future, as the technology matures and its application expands, it is expected to play a wider role in driving green and low-carbon development into a new phase.
