Voter Identity Verification
Public/Private Key Mechanism
Verifying the identity of voters is crucial in any voting system to prevent fraud and ensure the legitimacy of the process. Blockchain leverages a public/private key mechanism to verify the identity of participants. Each voter is assigned a unique pair of cryptographic keys, consisting of a public key for encryption and a private key for decryption. These keys are used to authenticate the voters and ensure that only eligible individuals can cast their votes. The public key can be openly shared, while the private key remains confidential, providing a secure mechanism for verifying voter identities.
Blockchain enhances the security of online voting systems by utilizing digital signatures. When a vote is cast, it is signed using the voter’s private key, creating a unique digital signature. This signature is mathematically linked to the voter’s identity and the encrypted vote, ensuring that the vote is authentic and has not been altered during transmission. By utilizing digital signatures, blockchain provides a robust mechanism for verifying the integrity and authenticity of each vote, enhancing the overall security of the online voting process.
While ensuring the authenticity of votes is crucial, preserving the anonymity of voters is equally important in maintaining the integrity of the voting process. Blockchain technology allows for the anonymization of votes by separating the identity of the voter from the actual vote.
