ICBC Develops Blockchain-Based Digital Vault File Indexing Technology to Enhance Data Security and Efficiency

On March 25, 2025, the National Intellectual Property Administration of China revealed that Industrial and Commercial Bank of China Limited (ICBC) filed a patent application for a "Construction Method and Device for File Indexing in a Blockchain-Based Digital Vault," with publication number CN119669158A and an application date of December 2024. This patent publication marks a significant step forward for ICBC in leveraging blockchain technology to improve data security and management efficiency.

The patent abstract indicates that this technology proposes a novel file indexing method and device designed to address the inaccuracies in existing file indexing systems caused by inconsistent file naming conventions, which hinder the effective identification of duplicate files. Traditional digital vault technologies have limitations in file management, such as chaotic file naming leading to difficult retrieval and the inability to easily identify duplicate files. These issues not only reduce data retrieval efficiency but also increase the complexity of data management and potentially lead to data loss or security risks. ICBC's patent aims to resolve these issues using blockchain technology and an innovative indexing method.

The core of this method lies in utilizing semantic vector technology for file indexing. Specifically, the method first receives N target files (where N is a positive integer) and identifies each file, obtaining the target identification results. Then, based on these results, semantic vectors are constructed for each file, resulting in N semantic vectors, each corresponding to a target file. These semantic vectors are not simple file names or tags, but vector representations that more accurately reflect the file content and meaning, making the indexing process more precise and reliable.

Next, the N semantic vectors are input into a module called the "chaotic index executor" for processing. This executor utilizes advanced algorithms to build a data structure called a "chaotic index tree" based on the semantic vectors. The chaotic index tree contains N branch nodes and their connections, with each branch node storing the semantic vector corresponding to a target file. This tree structure effectively organizes the file index information, making file retrieval more efficient. The term "chaotic" might suggest that the algorithm employs a non-linear or stochastic strategy to enhance the robustness and anti-interference capability of the index, maintaining efficient retrieval speed even with large amounts of data.

Through this indexing method based on semantic vectors and the chaotic index tree, ICBC's patented technology effectively addresses the shortcomings of traditional file indexing methods. Compared to simple methods based on file names or hash values, this method can more accurately identify files, avoiding indexing errors caused by inconsistent naming or similar file content. This is crucial for ensuring the accuracy and integrity of data within the blockchain-based digital vault, especially when dealing with large numbers of files with similar content.

The application of this technology to blockchain-based digital vaults will further enhance their security and efficiency. The decentralized and tamper-proof nature of blockchain technology, combined with the precise indexing method proposed in this patent, can effectively prevent data loss, tampering, and leakage, ensuring data integrity and reliability. Simultaneously, the efficient file indexing method significantly improves data retrieval speed and efficiency, allowing users to quickly find the required files. This is of significant practical importance for financial institutions, as it can effectively improve operational efficiency and reduce operating costs.

As one of China's largest commercial banks, ICBC has consistently explored and applied fintech to enhance its service capabilities and competitiveness. This patent application demonstrates ICBC's continuous innovation and investment in blockchain technology applications. This technology can not only be applied to ICBC's own business systems but also serve as a reference for other financial institutions, promoting the improvement of data security and management levels across the financial industry.

The successful application of this patent also reflects the strong government support for fintech innovation in China. In recent years, the Chinese government has issued a series of policies encouraging financial institutions to actively explore and apply new technologies, driving the digital transformation of the financial industry. ICBC's patent application is an excellent example of fintech innovation within this policy context.

According to Tianyancha data, ICBC was founded in 1985, is located in Beijing, has a registered capital of RMB 35,640,625.7089 million, and a paid-in capital of RMB 24,800,000 million. ICBC is a company primarily engaged in monetary financial services, with its business scope covering various aspects of commercial banking. Tianyancha data also shows that ICBC has invested in 30 companies, participated in 5,000 bidding projects, holds 981 trademark registrations, 5,000 patents, and 76 administrative licenses. This data fully demonstrates ICBC's strong capabilities and extensive business coverage. The blockchain-based digital vault file indexing patent is another achievement in ICBC's technological innovation, further solidifying its leading position in the fintech field. This not only benefits ICBC's core competitiveness but also contributes to the digital transformation and development of the entire financial industry.

ICBC's patented technology has profound implications for the future development of fintech. It can not only enhance data security and management efficiency but also provide a technological foundation for other innovative applications. For example, combined with artificial intelligence, it can further optimize file indexing and retrieval processes, achieving more intelligent data management. This will provide financial institutions with safer, more efficient, and convenient data services, driving the financial industry towards a higher level of development. With continuous technological advancements and expanding application scenarios, this patented technology may play a role in a wider range of fields, contributing to the construction of a digital society.

In conclusion, ICBC's patent application for a blockchain-based digital vault file indexing technology represents another breakthrough in the fintech field. Its innovative indexing method effectively addresses the pain points of traditional file management, providing financial institutions with a more secure and reliable data storage and management solution. The successful application of this technology will further promote the digital transformation of the financial industry and make significant contributions to building a safer and more efficient digital economy. In the future, as the technology matures and application scenarios expand, this technology will demonstrate even broader application prospects.
