The blockchain-based voting system with authentication through Aadhaar number, voter ID, face unlock, and password combines secure identification methods with the transparency and immutability of blockchain. Voters register with their Aadhaar number and voter ID, create a password, and undergo face unlock for authentication. The system uses blockchain to record each vote as a transaction, ensuring transparency and preventing tampering. Independent verification is possible, and the system generates accurate results by counting the cryptographic hashes stored in the blocks. Overall, the system provides a secure, transparent, and efficient voting process while maintaining privacy.
