In 2005, the Human Centered Computing Lab at Auburn University created the first version of Prime III. Prime III is an electronic voting system that offers a secure, open-source, multimodal electronic voting system that delivers the necessary system security, integrity and user satisfaction safeguards in a user friendly interface that accommodates all people regardless of ability. Prime III's implements a Universal Design. By Universal Design, we mean " an approach to the design of all products and environments to be as usable as possible by as many people as possible regardless of age, ability or situation. Other terms for Universal Design used around the world include Design For All, Inclusive Design, and Barrier-Free Design." (Universal Design Education Online) Essentially, if you are illiterate, cannot see, hear or if you have a physical disability, i.e. arthritis, you are still able to vote using Prime III in a private, secure environment without assistance. Prime III is incorporated into the current voting process that the voter is accustomed to using. The voting process begins when the voter enters the voting precinct and is verified using the standard procedures in each precinct/state. When the voter enters the voting area, s/he will be assigned a voting booth by a poll worker. The poll worker initiates the Prime III session and the voter cast his/her ballot unassisted! Voters can cast their ballots using touch and/or voice. Prime III uses a uniquely designed touch screen that allows sighted voters to easily cast their ballots by simply touching their selections. Prime III uses a headset with a microphone to allow voters to privately cast their ballots using their voice. Voters that use the headset to vote will receive prompts that speak the ballot options currently displayed. Each option is randomly assigned a number. If the choices are Democrat, Republican, Green Party; Prime III will prompt the user with something similar to “To vote for the democratic party, say four <beep> to vote for the republican party, say three <beep> to vote for the green party, say two <beep>”. The voter will simply speak the number associated with her/his choice. As such, eavesdroppers will hear a voter speaking numbers with no indication of the voter’s choices. From a security perspective, Prime III uses multiple encryption schemes to securely store each ballot amongst several encrypted imposter ballots. This makes modifying the actual ballots more difficult. Furthermore, each Prime III machine is attached to two separate video recorders that capture all the interactions that occur on each machine. The video is directly connected to each machine; therefore, the voters’ identity is not captured on the video. This is video surveillance of the software, not the voter. The video provides a voter-verifiable video audit trail (VVVAT). Before the voter cast his/her ballot, the voter must verify the ballot by touch and/or voice twice. Together, Prime III’s usability and security create a usable security model that uses election administration and training to create a secure, yet easy to manage election process.
