China Construction Bank (CCB) Applies for Blockchain Data Verification Patent to Enhance Financial Data Security

On March 21, 2025, the State Intellectual Property Office of China revealed that China Construction Bank Corporation (CCB) filed a patent application titled "Data Verification Method, Device, Equipment, Medium, and Product," with publication number CN119646007A, submitted in November 2024. This patent application aims to enhance financial data security, with its core technology focusing on blockchain data verification. It provides strong support for CCB's technological innovation in the fintech sector.

The patent abstract indicates that it relates to information security technology and proposes a novel data verification method, device, equipment, medium, and product. The core of the method lies in verifying the integrity and consistency of transaction data by querying multiple blockchain nodes. This effectively improves the security and reliability of financial transactions. Specifically, the method includes the following steps: first, receiving a query request from a transaction response device, which contains the target transaction identifier; then, the system queries multiple blockchain nodes to confirm whether the first transaction data corresponding to the target transaction identifier is recorded; if the data is found in a blockchain node (the first target blockchain node), the system sends the first target information to the transaction response device; next, the system receives the second transaction data sent by the transaction response device and uses another blockchain node (the second target blockchain node) to verify the authenticity of this data; finally, if the first and second transaction data are consistent, the system writes the data from these two nodes into the database, completing the data verification.

The innovation lies in the timely verification of transaction data corresponding to the same transaction, effectively preventing data tampering or loss during transmission, thus significantly improving the security of resource information. Traditional financial transaction systems often rely on a single data source for data verification. If this data source encounters a problem, the security of the entire system is severely threatened. The patent application by CCB, through a multi-node verification mechanism, effectively avoids single points of failure, enhancing the system's fault tolerance and security.

This technology has broad application prospects. In the financial sector, especially in scenarios involving high-value transactions and sensitive information, data security is paramount. The application of this technology can effectively improve the security of financial transactions, reduce risks, and safeguard customer assets. It can also be applied to other fields requiring high data security, such as healthcare and government.
