Voter Authentication is the process of verifying the identity of individuals who wish to vote in an election. This ensures that only eligible voters can cast their ballots, helping to maintain the integrity of the electoral process. Methods of authentication can include presenting identification documents, using biometric data, or confirming registration details. Effective voter authentication helps prevent issues such as voter fraud and ensures that each vote counts. Different regions may have varying requirements for authentication, which can include photo IDs, signature matching, or online verification systems, depending on local laws and regulations.
