Patent Granted for Blockchain-Based Secure Data Interaction Method: Elevating Data Security to New Heights

On December 5, 2024, the State Intellectual Property Office of China announced the publication of a patent (publication number CN119066707A) applied for by Beijing Password Cloud Core Technology Co., Ltd. The patent, titled "Blockchain-Based Data Secure Interaction Method, Apparatus, Device, and Storage Medium," was filed in August 2024. This marks a significant breakthrough in data security, leveraging blockchain technology to achieve more secure and reliable data interaction and providing enhanced protection for sensitive information.

The core of this patented technology lies in a novel data secure interaction method. It cleverly combines the decentralized, transparent, and immutable characteristics of blockchain with cryptographic encryption and decryption techniques, effectively addressing security vulnerabilities inherent in traditional data interaction methods. Traditional encryption methods often rely on centralized key management systems, making them vulnerable to single points of failure and security breaches. This patented technology mitigates this risk by using blockchain to decentralize key management, significantly improving system security and reliability.

The patent abstract details the method's workflow: First, the data sender transmits the encrypted ciphertext and the target public key to the system. The system generates a private key retrieval request based on the target public key and sends it to the blockchain. The blockchain, acting as a trusted intermediary, uses the private key retrieval request to locate the target private key matching the target public key. To further enhance security, the target private key is split into two parts: a first private key shard and a second private key shard. The first shard is sent to the data requester, and the second shard is sent to a collaborative decryption party. This key splitting mechanism ensures that even if one party is compromised, the data cannot be decrypted independently, effectively preventing key leakage.

Next, the system calculates a first intermediate value from the encrypted ciphertext and sends it to the collaborative decryption party via the blockchain. Upon receiving the intermediate value, the collaborative decryption party combines it with the second private key shard to calculate a second intermediate value, which is then sent to the data requester via the blockchain. Finally, the data requester uses the received second intermediate value and the first private key shard to decrypt the ciphertext, obtaining the required plaintext data.

The entire process relies on the blockchain's immutability, ensuring data integrity and preventing malicious tampering or theft during transmission and decryption. The distributed ledger technology of blockchain allows the entire interaction process to be transparently recorded and traced, improving audit efficiency and transparency, and facilitating supervision of data interaction.

This patented technology has broad application prospects. Financial, medical, and governmental sectors have extremely high data security requirements that traditional security measures often struggle to meet. This blockchain-based data secure interaction method will provide strong security guarantees for these sectors, effectively reducing the risk of data breaches.

Specifically, in finance, this technology can be applied to cross-bank transactions and payment settlements to ensure the security and integrity of transaction information. In healthcare, it can protect sensitive patient medical information, preventing leaks and misuse. In government, it can be used in identity authentication and data sharing to improve the security and efficiency of government data management.

Furthermore, this patented technology exhibits good scalability and portability. It can be integrated with various existing data security technologies to further enhance data protection capabilities. For instance, it can be combined with artificial intelligence for more intelligent security protection.

In conclusion, this blockchain-based data secure interaction method patent applied for by Beijing Password Cloud Core Technology Co., Ltd., represents a major leap in data security technology. It fully leverages the advantages of blockchain and cryptographic technologies, providing a secure and reliable data interaction solution. The application of this technology will significantly enhance data security and reliability, laying a solid foundation for building a more secure and trustworthy digital society. The publication of this patent also provides valuable guidance and reference for other research institutions and companies, driving technological advancements in the field of data security. With ongoing maturation and refinement, this technology will find wider application in more fields, making even greater contributions to data security. It is poised to play an increasingly important role in driving the development of the digital economy and supporting the construction of a more secure and reliable digital society. The successful application of this patent also demonstrates China's significant progress in blockchain technology and its applications, reflecting the nation's emphasis on information security and technological innovation.

The innovation lies not in simply applying blockchain to data storage or transmission, but in cleverly integrating it into the entire data interaction process, effectively combining key management, encryption/decryption, and data verification. This multi-layered security protection mechanism makes the technology highly resilient and reliable against various security threats. This is crucial for maintaining information security and ensuring the healthy development of the digital economy. It is expected that this technology will see wider application and promotion in the future, contributing significantly to the construction of a safer and more reliable digital society.
