An Overview of Joint Biometric Identification for Secure Online Voting with Blockchain Technology

Nowadays, voting is done electronically, which has various characteristics which is different from current voting methods. Though there are many demerits in the e-voting systems like voter fraud, requires high security features, damages to the machines can cause the problem of loss of votes. This provides many of the advanced features compared to the other voting mechanisms. These drawbacks can overcome by Online E-Voting with joint biological identity-based authentication such face and finger print based biometric authentication system. The feature extraction process uses the algorithm of Haar-Cascade for face recognition and Minutiae features for finger print recognition. The biometric data are encrypted and stored in voting database secure manner. These details are stored in database for further validation. The encryption process utilizes the ECC algorithm. For login process user will check using OTP and voter id details. Then the biometric verification is processing for predicting user authentication. Then voters are allowed to make vote for specific candidate. Blockchain is an emerging technology which is used for securing the votes and hashes in cryptography is used for the verification of the voters. A Successful vote can be considered as a transaction in blockchain. Each vote is stored as a block in the backend database of the blockchain. This offers features like one person one vote of the voting mechanism. The user-friendly interface fosters a seamless voting experience, while robust security features safeguard against fraud and multiple voting.
