Title: Bin Qian: Blockchain and Digital Trust Innovations.
Introduction
Bin Qian is an inventor associated with Guangzhou, China. His patent work addresses blockchain-based voting and timestamp generation, with an emphasis on privacy, verification, and trusted digital records. He is associated with Guizhou Power Grid Co., Ltd. and the Power Research Institute of China Southern Power Grid. His portfolio includes 2 patents.
Latest Patents
Qian’s listed patents include “Blockchain-Based Anonymous Trusted Voting Method, Apparatus and Related Device” and “Timestamp Generation Method and Apparatus, and Electronic Device and Storage Medium.”
The blockchain-based voting invention describes a process for hashing voting content, blinding commitment values using information from other voters, and signing commitment-value tuples. After other voters verify the signature, the method forms a vote tuple and uploads it, along with related commitment information, to a blockchain. The commitment information supports decrypting the vote tuple, while the process is designed to enable trusted anonymous voting.
The timestamp-generation invention offers an alternative to relying on a conventional trusted third party as a timestamp authority. It obtains a file record, calculates its hash, 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. This approach is intended to reduce the risk of recorded information being exposed through a centralized timestamping process.
