Latest Patents

Blockchain-Based Anonymous Trusted Voting Method, Apparatus and Related Device. This invention describes a trusted anonymous voting method that hashes 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. After other voters verify the signature, the method forms a vote tuple and uploads it, along with a related commitment tuple, to a blockchain. The commitment tuple can be used to decrypt the vote tuple.

Timestamp Generation Method and Apparatus, and Electronic Device and Storage Medium. This invention proposes a timestamping approach intended to reduce the risk of information leakage associated with relying on a traditional trusted third-party timestamp authority. The method hashes a file record and sends the hash to a random issuer. The issuer signs the hash and the time it received it, then returns the signature result, which is stored on a blockchain as the file’s timestamp.
