This Could be Microsoft's Most Important Product in 2020. If It Works...

Microsoft's ElectionGuard system.

Building 83 doesn't stand out on Microsoft's massive Redmond, Washington, headquarters. But last week, the nameless structure hosted what might be the software giant's most important product of 2020.

Tucked away in the corner of a meeting room, a sign reading "ElectionGuard" identifies a touchscreen that asks people to cast their votes. An Xbox adaptive controller is connected to it, as are an all-white printer and a white ballot box for paper votes. If you didn't look carefully, you might have mistaken all that for an array of office supplies.

ElectionGuard is open-source voting-machine software that Microsoft announced in May 2019. In Microsoft's demo, voters make their choices by touchscreen before printing out two copies. A voter is supposed to double-check one copy before placing it into a ballot box to be counted by election workers. The other is a backup record with a QR code the voter can use to check that the vote was counted after polls close. 

With ElectionGuard, Microsoft isn't setting out to create an unhackable vote -- no one thinks that's possible -- but rather a vote in which hacks would be quickly noticed.
