Transparency and Access to Source Code in E-Voting

Abstract

We examine the potential role of source code disclosure and open source code requirements in promoting technical improvements and increasing transparency of voting systems. We describe the enclosure of transparency of voting technology that has occurred over the course of United States' electoral history, the implications that source code disclosure has for transparency, the negative effects that enclosing transparency has had at different levels and the regulatory and legislative efforts to increase access to source code. We then look at the benefits and risks of open and disclosed source code regimes for voting systems, efforts to provide open source voting systems, existing open source business models that might translate to the voting systems context, regulatory and market barriers to disclosed or open source code in voting systems and alternatives that might exist outside of public disclosure of source code. We conclude that disclosure of full system source code to qualified individuals will promote technical improvements in voting systems while limiting some of the potential risks associated with full public disclosure.
