Latest Patents

Xiao’s listed patents address ways to use blockchain technology to support privacy, verification, and recordkeeping.

- **Blockchain-Based Anonymous Trusted Voting Method, Apparatus and Related Device.** This invention describes a voting process that hashes the original voting content, blinds commitment values using information from other voters, and uses digital signatures to support verification. The resulting vote information and related commitment values are uploaded to a blockchain, where the commitment values can be used to decrypt the vote tuple. The approach is designed to enable trusted anonymous voting.

- **Timestamp Generation Method and Apparatus, and Electronic Device and Storage Medium.** This invention proposes a timestamping process that does not rely on a traditional trusted third-party timestamp authority to record information. It hashes a file record and sends the hash to a random issuer, which signs the hash together with its receiving time. The signature result is then stored on a blockchain as the file’s timestamp.
