Thread 1. Lawsuit being filed in #Florida today to force #election officials to preserve digital images of #ballots. Digital ballot images are photos of the ballot made when the ballot is scanned. New generation scanners create these images automatically.

2. Fun Fact: Scanners don't count the paper ballot. They take a photo (the digital ballot image) & count info from that photo. So the digital ballot image is part of the chain of custody of the vote & must be preserved. Courts in AZ confirmed this. This is a digital ballot image. 
3. Digital ballot images can be manipulated. This was demonstrated at a 2019 @defcon @VotingVillageDC talk by Kart Kandula & Jeremy Wink, students at @UMich. Because of this it's important to use the original paper ballot for all official audits.
