Scott Jones will present: Negative Space Signaling: A Threat to Election Integrity?

The aftermath of the 2020 election in Georgia has produced many questions regarding election integrity, including the integrity of the state’s recently purchased Ballot Marking Devices, used statewide, which produce paper records for each voter.

In the interest of improving election transparency, there have been calls to release digital scans of all ballots, which are presumably de-identified. However, it will be demonstrated that markings in the unused space of the paper ballots can allow, either intentionally or unintentionally, “out of band” messages to be passed through publicly disclosed digital copies of the ballots, which can then threaten election integrity.

Scott M. Jones is acting director of Electronic Frontiers Georgia, a local activist group promoting and advocating for the protection of online civil liberties. Mr. Jones is also the Director of the Electronic Frontiers Forums track at DragonCon, a lecture series covering the intersection of technology, law, activism, and society. Mr. Jones has been involved in advocacy for Internet- and technology-related civil liberties since the mid-1990’s. In his day job, Mr. Jones is a system administrator for a small startup and consulting firm in the insurance industry.


We will have time after the presentation for people to to share what they are working on. Your project doesn’t have to be complete and slides are not required (like show-n-tell).
