Digital Voting Platform Using Blockchain Segmentation and Trusted Third Party

The patent introduces a Trusted Third Party (TTP) as an intermediary that issues cryptographic key pairs to voters and manages the public key infrastructure. This mediator handles the sensitive key management operations, isolating the vulnerability from the core voting process. The TTP signs voter registrations and manages ballot issuance, creating a trusted layer that protects both voter privacy and vote authenticity without requiring voters to directly manage complex cryptographic keys.

The patent segments the voting system into distinct functional blocks implemented as smart contracts on the Blockchain: voter registration block, ballot issuance block, voting block, and result tallying block. Each block handles a specific aspect of the voting process independently. This segmentation allows the system to achieve vote integrity through distributed immutable recording while managing complexity by dividing functions into modular, independently verifiable components that can be implemented and audited separately.

The patent implements a unified cryptographic authentication mechanism that serves multiple functions: it provides multi-factor authentication by combining something the voter knows (password) with something the voter possesses (cryptographic key pair), while also enabling digital signing of votes, voter identity verification, and ballot receipt confirmation. This universal authentication approach enhances authorization security without requiring voters to learn and manage multiple separate authentication systems, thereby maintaining relative ease of operation.
