Punchscan: Introduction and System Definition of a High-Integrity Election System

Punchscan is a unique hybrid paper/electronic voting system concept. As a receipt-based system, Punchscan provides high voter privacy and election integrity, yet it does not rely on the complex and fragile electronic voting machines found in many current implementations. In this paper, we define the Punchscan system and voting protocol, including the people, objects and events involved and the ways they interact. We also trace the flow of data throughout the election process. This definition will aid those implementing the Punchscan system, but also lays a foundation for critical analysis and discussion within the voting research community.
