Abstract

Electronic democracy has addressed issues like anonymity and competency associated with traditional democracy, it brings its own challenges, including oversight of vote counting. The proposed blockchain based online voting system integrates advanced security features, including unique identification keys, fingerprint authentication, and one-time passwords. To make sure that the security and integrity of voting process, we employ 128-bit AES encryption, SHA-256, and blockchain technology. Votes are recorded as transactions within a blockchain, ensuring atomicity and integrity. This approach addresses the challenges of existing voting systems, offering an efficient and secure electronic voting solution.
