Latest Patents

Blockchain-Based Anonymous Trusted Voting Method, Apparatus and Related Device. This invention describes a trusted anonymous voting method that hashes the original voting content to produce a commitment value. The value is blinded using information from other voters, and an ESDSA signature is generated for the resulting commitment tuple. The method then forms a vote tuple using the commitment and signature information, and uploads it and related commitment data to a blockchain. The approach is designed to support verification and enable decryption of the vote tuple.

Timestamp Generation Method and Apparatus, and Electronic Device and Storage Medium. This invention addresses the risk of information leakage associated with traditional timestamp systems that rely on a trusted third-party timestamp authority. The method hashes a file record and sends the hash to a random issuer. The issuer signs the hash together with the time it received it, and the resulting signature is stored on a blockchain as the file’s timestamp.

Career Highlights

Deng has been associated with Guizhou Power Grid Co., Ltd. and the Power Research Institute of China Southern Power Grid. His listed patent work applies blockchain technology to voting and timestamp records.

Collaborations

His listed coworkers include Ji Wang and Bin Qian. The patent descriptions also refer to participation by other voters and a random issuer in the respective systems.

Conclusion

Yaodan Deng’s two listed patents focus on using blockchain to support anonymous voting and timestamp generation, with an emphasis on verification, record integrity, and reducing reliance on traditional trusted intermediaries.
