An Optical Scan E-Voting System based on N-Version Programming

This article presents Demotek, a multi-agent prototype for an electronic voting system based on optical character recognition technology. Trade-offs in voter training, ease of use, security, and coercion across various systems are considered for the purpose of recognizing achievable improvements. Based on the use of N-version programming techniques, we propose improvements to Demotek, including those in security and new capabilities. This case study demonstrates how the voter´s authentication system and vote data transmission could further simplify and improve the electoral process by adding these new capabilities to the electronic voting system using N-version programming.
