Title: Zhenghao Gao and Blockchain-Based Timestamp Generation.
Introduction
Zhenghao Gao is an inventor associated with Guiyang, China. His patent work addresses trusted timestamp generation and the protection of recorded information.
Latest Patents
Gao is associated with 1 patent: “Timestamp Generation Method and Apparatus, and Electronic Device and Storage Medium.” The invention aims to reduce the risk of information leakage that can arise when traditional timestamp systems rely on a trusted third party to record information.
The method acquires a file record and calculates its hash value. It sends the hash to a random issuer, which signs the hash together with the time it received it. The resulting signature is then stored on a blockchain as the file record’s timestamp.
Career Highlights
Gao’s listed professional affiliations include the Electric Power Research Institute, China Southern Power Grid, and Guizhou Power Grid Co., Ltd. His patent describes an approach that combines digital signatures and blockchain storage to create timestamps without relying on a conventional timestamp authority.
Collaborations
Gao’s listed coworkers include Fan Zhang and Jiaxiang Ou.
Conclusion
Zhenghao Gao’s patent focuses on using a signed receipt time and blockchain storage to provide an alternative method for timestamping file records.
