Beijing Yimi Technology Applies for a Patent on a "Blockchain Identity Privacy Protection System" Enabling Controllable Anonymous Supervision

On January 18, 2025, the State Intellectual Property Office of China revealed that Beijing Yimi Technology Co., Ltd. had applied for a patent titled "A Blockchain Identity Privacy Protection System," with publication number CN119316152A and an application date of December 2024. The core of this patented technology lies in enabling regulatory authorities to offline identify the true identities of transaction parties when necessary, while simultaneously ensuring the privacy of their identities during transactions. This achieves a controllable anonymous supervision model, which is of significant practical importance in today's digital age, where data security and privacy protection are highly valued.

The patent abstract details the system's composition and operating mechanism. The system primarily consists of four components: users, an authentication center, transaction verifiers, and regulators. Users are further divided into receivers and senders, each generating a key pair (public key and private key). Before a transaction, both the receiver and sender submit real-name authentication requests to the authentication center using their respective public keys, completing identity verification. This step ensures the authenticity of the transaction participants, laying the foundation for subsequent privacy protection and supervision.

After identity verification, the sender uses their public key and the receiver's public key to generate a one-time public key. This one-time key is used only for the current transaction and discarded afterward, effectively preventing security risks stemming from key leakage. The sender then uses this one-time public key to generate transaction information. Importantly, the transaction information itself does not directly contain the real identity information of the sender and receiver, which is the key to the system's privacy protection.

Regulators extract regulatory ciphertext from the transaction information. This ciphertext is not directly readable information but encrypted data. Regulators possess a dedicated regulatory key (private key), which is the only key capable of decrypting the regulatory ciphertext to obtain the real identities of the sender and receiver. This design cleverly implements offline supervision: regulators do not need to monitor all transactions in real-time; decryption only occurs when investigating a specific transaction, maximizing user privacy.

The innovation of this patented technology lies in its combination of blockchain technology and zero-knowledge proof technology. Quantum-resistant zero-knowledge proof technology ensures the correct operation of the protocol while reducing computational resources and time consumption. Zero-knowledge proof technology allows verifiers to verify the truthfulness of a statement without knowing the specific content of the statement. In this system, this guarantees the authenticity of the transaction while concealing the specific identity information of the transaction participants. This not only improves system efficiency but also enhances security, effectively resisting potential attacks.

The system's security is further reinforced by its strict control over key management. The use of one-time public keys effectively reduces the risk of key leakage; even if a key is stolen, it will not affect the security of other transactions. Strict management of the regulatory key ensures that only when necessary can regulators access the real identity information of transaction participants, further protecting user privacy and data security.

In summary, Beijing Yimi Technology's patented "Blockchain Identity Privacy Protection System" demonstrates a commitment to user privacy and data security, cleverly balancing privacy protection and regulatory needs. By combining blockchain technology, zero-knowledge proof technology, and strict key management mechanisms, the system achieves a controllable anonymous supervision model, providing crucial technological support for the future development of the digital economy. This technology has broad application prospects across various fields, including finance, healthcare, and identity authentication, contributing to the creation of a safer and more reliable digital society.

Beijing Yimi Technology Co., Ltd., established in 2023, has a registered capital of 5 million RMB and a paid-in capital of 1.5 million RMB.
