China Mobile Suzhou's Patent Application for a Data Verification Method and Related Device Enhances Data Security and Integrity

On November 27, 2024, the State Intellectual Property Office of China announced that China Mobile (Suzhou) Software Technology Co., Ltd. had applied for a patent titled "Data Verification Method, Apparatus, and Related Equipment," with publication number CN119026180A and application date in July 2024. This patent aims to improve data verification effectiveness, enhancing data security and integrity. Its core technology involves verifying data using a combination of server and blockchain technologies.

The patent abstract details the proposed data verification method, apparatus, and related equipment, designed for client-side applications. The core process is as follows: first, the data to be stored is encrypted, generating encrypted ciphertext and signature data. The system then uploads the encrypted ciphertext and hash data to the server, and simultaneously uploads the encrypted ciphertext and signature data to the blockchain. Significantly, the patent employs a "dual insurance" strategy, storing data on both the server and the blockchain, rather than relying on a single storage and verification method.

Next, the client sends a first data verification request to the server and a second data verification request to the blockchain. Upon receiving the first request, the server returns first feedback information; similarly, the blockchain returns second feedback information upon receiving the second request. By comparing the feedback from the server and the blockchain, the client can effectively verify the data's integrity and authenticity. This dual verification mechanism significantly improves the reliability of data verification and effectively mitigates the risk of single points of failure. If one verification stage encounters a problem, the other can still provide a reference for data verification.

The patent's innovation lies in its clever combination of server and blockchain technologies. The server provides fast data access and processing capabilities, while the blockchain ensures data immutability and transparency. Uploading encrypted ciphertext and hash data to the server enables fast data access and verification; simultaneously uploading encrypted ciphertext and signature data to the blockchain ensures data integrity and security, preventing malicious alteration or destruction. This combination achieves a good balance between data security and efficiency.

Specifically, uploading hash data to the server is primarily for fast data verification and comparison. The server can quickly compute and compare hash data, thus rapidly verifying data integrity. Uploading signature data and encrypted ciphertext to the blockchain focuses on long-term data security and immutability. Blockchain technology's inherent properties guarantee data immutability; even if the server fails or data is maliciously altered, the data on the blockchain remains a reliable reference, ensuring data authenticity.

This patented technology has wide-ranging applications in areas requiring data security and integrity, such as finance, healthcare, and the Internet of Things (IoT). In finance, it can safeguard transaction data security and authenticity, preventing fraud. In healthcare, it protects patient medical data security and privacy, preventing data breaches and tampering. In IoT, it ensures the security and reliability of IoT device data, preventing malicious attacks.

China Mobile (Suzhou) Software Technology Co., Ltd.'s patent application demonstrates its innovative capabilities and proactive exploration in data security technology. This technology not only improves data verification effectiveness but also enhances data security and integrity, providing more reliable data security for various applications. With further development and application, it is expected to positively impact data security across various industries.

This patented technology could also play a significant role in data traceability. Since data is backed up on both the server and the blockchain, the data's origin and modification history can be clearly traced, which is crucial for resolving data disputes and assigning responsibility. This improves data transparency and trustworthiness, creating a more secure and reliable data environment.

In summary, China Mobile (Suzhou) Software Technology Co., Ltd.'s patent application for "Data Verification Method, Apparatus, and Related Equipment" represents a significant innovation in data security technology. Its proposed dual verification mechanism combining server and blockchain technologies effectively improves data verification, enhances data security and integrity, and provides new technical means for building a more secure and reliable data environment. The widespread application of this technology will have a profound impact on data security across various industries. With continued development and improvement, this technology is expected to find application in even more fields, better safeguarding data security and promoting the healthy development of the information society.
