Aerospace Information Technology Applies for "Privacy Data Comparison System" Patent: A New Breakthrough in Data Security

On April 2nd, 2025, the State Intellectual Property Office of China announced that Aerospace Information Technology Co., Ltd. had applied for a patent entitled "A Privacy Data Comparison System, Method, Device, Equipment, and Medium," with publication number CN119739790A and an application date of December 2024. The core of this patented technology lies in its novel method for comparing privacy data without revealing the data itself, representing a significant breakthrough in data security.

The patent abstract details the system's mechanism. Terminal devices first use a first zero-knowledge proof tool to encrypt the privacy data, generating a corresponding first commitment value and first random value. The system then retrieves relevant verification data from a blockchain platform, including a corresponding second commitment value and second random value. Based on the privacy data, the first commitment value, the first random value, the verification data, the second commitment value, and the second random value, the system generates an encrypted result called the "first proof." Thereafter, the terminal device only needs to send the generated first proof and first commitment value to the blockchain platform, without transmitting the original privacy data.

The blockchain platform then uses a preset subtraction verification function to verify the received first proof, first commitment value, and second commitment value, ultimately deriving the comparison result of the privacy data. This ingenious design effectively prevents the leakage or tampering of privacy data during transmission, ensuring data security. The core of the entire process is the application of zero-knowledge proof technology, which allows one party to prove the truth of an assertion without revealing any information. In this patented technology, zero-knowledge proof technology is used to prove the comparison result of two pieces of privacy data without revealing the specific numerical values.

This technology boasts extensive application prospects. Many sectors, including healthcare, finance, and government, have extremely high requirements for the security protection of privacy data. Traditional data comparison methods often require the transmission of raw data, significantly increasing the risk of data leakage. The patent technology proposed by Aerospace Information Technology effectively solves this problem. By implementing data comparison on a blockchain platform, the system not only enhances data security but also increases the transparency and traceability of data processing. The decentralized nature of blockchain technology further enhances system security, preventing single points of failure and data tampering.

Aerospace Information Technology Co., Ltd., a company with many years of experience in telecommunications, broadcasting, television, and satellite transmission services, has applied for a patent technology that is not directly related to its main business, yet reflects the company's exploration and investment in technological innovation and cutting-edge technology.
