A Secured Online Voting System by Using Blockchain as the Medium

The secured online voting system aspires to achieve its objective by developing a website for eligible voters to cast their votes online in a secured manner. This system is designed to ease the difficulties and tedious procedures that voters would have to endure when they seek to cast their votes during the polling day. Secure computer algorithms would immensely improve efficiency while reducing the amount of time for the entire operation and eradicating human errors. When diversifying traditional voting systems into an online voting system, an essential factor that should be considered is cybersecurity. Online voting systems are vulnerable to attacks performed by hackers. This brought about the need to develop a fully secured online voting system. Various researches have been conducted using multiple algorithms to construct a secured online voting system that includes steganography, visual cryptography, hybrid crypto realm, encryption, digital signature, and biometric security. This paper reviews various secured online voting systems in the body of knowledge and utilizing public-key cryptography, digital signature, steganography, and many more. A particular emphasis would be given on blockchain technology's role in the secured online voting system, mainly to preserve the voting tracking system's integrity and authenticity
