People in the small Wisconsin town of Fulton are the first to try out software Microsoft designed to confirm that votes are being properly counted. On Tuesday, Fulton residents are using the technology while choosing who will join the local school board and hold a seat on Wisconsin's state supreme court.

Microsoft's ElectionGuard software can count votes electronically while providing a separate means for voters to confirm that their votes are included in tallies, Tom Burt, Microsoft's corporate vice president for customer security and trust, said Thursday.

Votes themselves are encrypted using a technique developed by Microsoft Research, so that nobody can see how an individual voted, Burt explained in a media briefing at company headquarters in Redmond, Washington. After a person votes, a printer next to the voting device generates a piece of paper, which the voter can view to make sure the votes were recorded properly and then drop into the ballot box. The paper also shows an online location that voters can look at later to make sure their vote was counted, although this web site doesn't show who they voted for, he said.

The ElectionGuard technology won't be responsible for tallying votes in the Wisconsin primary election, however. Election officials will still count paper votes for the primary, a Wisconsin Elections Commission spokesperson told CNBC on Tuesday. It is technologically possible for a jurisdiction to rely on the software's digital counts and then fall back to paper ballots for verification, but the systems featuring Microsoft technology that people are using in Fulton on Tuesday have not been certified with the state, the spokesperson said.

Microsoft said ElectionGuard won't be material to the company's business, since it's free to use, and that the company has no intention of entering the voting-hardware market. It's simply meant to help restore people's faith in voting, the company said.

If it works, it could make Microsoft look like it's helping with the democratic process. That would be in contrast to companies such as Facebook and Twitter, which have seen their technology used for political aims in ways they say they never intended.

As a first step, Microsoft worked with state, county and town election officials and nonprofit voting machine company VotingWorks to embed ElectionGuard into voting devices that people are using in Fulton, which has a population of 3,257.
