Construction Bank Applies for Blockchain Data Verification Patent: Innovative Technology Enhances Data Security

On November 27, 2024, the State Intellectual Property Office of China revealed that China Construction Bank Corporation (hereinafter referred to as "CCB") has applied for a patent titled "Data Verification Method, Device, Equipment, and Computer Storage Medium," with publication number CN119026183A and an application date of August 2024. This patent technology, applied in the blockchain field, aims to enhance data security and integrity, providing a novel technical solution for data management in the financial sector.

The patent abstract details the core mechanism of this data verification method. First, the method utilizes a preset encryption algorithm to encrypt data before storage, generating a unique integrity checksum. This checksum acts like a data "fingerprint," accurately reflecting the data's integrity and unaltered state. The system then stores the data in a data warehouse and simultaneously stores the generated checksum in both the blockchain and the data warehouse two independent storage spaces. This dual storage mechanism is a key highlight of the patent, effectively mitigating single points of failure and enhancing data security reliability.

During data verification, the system uses a preset method to simultaneously retrieve the two checksums stored in the blockchain and the data warehouse, referred to as the "first checksum" and "second checksum," respectively. The system compares these two checksums. If they are identical, it indicates that the data has not been tampered with during storage or transmission. The system records this result and saves it in the data warehouse. Conversely, if the checksums differ, it suggests potential unauthorized modification or other security threats, prompting an alert and triggering appropriate security measures.

The core advantage of this patent technology lies in its dual verification mechanism. By storing the integrity checksum in both the blockchain and the data warehouse, CCB cleverly leverages the immutability of blockchain technology and the large storage capacity of data warehouses to create a more secure and reliable data verification system. Traditional single-storage methods are vulnerable to data tampering or loss, risks effectively mitigated by this patent technology. The introduction of blockchain technology significantly enhances the security of the checksum. Due to blockchain's decentralized and immutable nature, even if the checksum in the data warehouse is maliciously altered, the checksum stored on the blockchain remains a reliable reference, ensuring data authenticity and integrity.

Furthermore, the patent technology considers practical application scenarios, such as the flexibility and configurability of the preset verification method. System administrators can adjust the parameters and strategies of the verification method based on actual conditions to accommodate different data types and security requirements. This configurability allows the technology to be widely applied in various financial business scenarios, including payment settlement, account management, and risk control, providing more comprehensive data security protection for financial institutions.

As a leading commercial bank in China, CCB has been committed to promoting financial technology innovation, continuously exploring and applying advanced technologies to improve service quality and risk management. The application of this blockchain data verification patent reflects CCB's ongoing innovation and exploration in the fintech field. It not only effectively enhances data security and integrity but also provides a valuable reference for other financial institutions, driving technological advancement across the financial industry.

This technology is of significant importance for maintaining financial security. In the current context of increasingly severe data security challenges, effectively safeguarding data integrity and security is a major concern for financial institutions. CCB's patent technology offers an effective solution to this problem, preventing data tampering or loss and ensuring the authenticity and reliability of financial transactions, thereby maintaining the stability and healthy development of the financial market.

This technology also boasts broad application prospects. Besides the financial sector, it can be applied to other industries requiring high data security, such as healthcare, education, and government. Data integrity and security are equally critical in these sectors, and this technology can provide reliable data security protection, facilitating secure data sharing and utilization.

In conclusion, CCB's applied blockchain data verification patent is an innovative and practical technological achievement. By combining blockchain technology with traditional data warehouse technology, it effectively enhances data security and integrity, providing new solutions for data security in the financial and other industries, and showcasing CCB's leading position and innovative capabilities in fintech. The application of this technology will further drive the development of financial technology and provide a solid foundation for building a more secure and reliable digital economy. This initiative by CCB also provides valuable experience and guidance for other financial institutions, driving progress in data security across the industry. In the future, with technological maturation and expanding application scenarios, this technology will play an even greater role in building a more secure and reliable digital economy.
