New "hybrid" voting system can change paper ballot after it's been cast
Paper ballots are safe only if marked by hand, not by machine
These “dieselgate” defects, however, are just the latest example of the myriad problems that inevitably arise whenever you place a hackable machine between voters and their ballots. Here are some of the other well-established problems that have caused most independent cybersecurity experts to recommend hand-marked paper ballots (counted on scanners or by hand) as a primary voting system:
Most ballot marking devices (BMDs) that are intended for use as a primary voting system put barcodes on the paper printouts, which purport to encapsulate the voters’ selections. Although voters can’t read barcodes, the barcodes are the only portion of the printout counted as their vote.
The barcodes can be maliciously programmed to instruct the scanners to flip votes.
Although the machine-marked printouts also include human readable text purporting to summarize the voters’ selections, it is up to the voters to catch any erroneous or fraudulent machine-marked selections within that text. A recent study suggests that most voters don’t review the text, even when instructed to do so. Often, voters who do undertake such a review fail to catch inaccuracies.
A manual audit or recount based on corrupted machine-marked printouts would itself be corrupted.
Touchscreens lead to frequent user error. (As noted, BMDs and hybrids are touchscreen systems.)
Touchscreens enable corrupt officials to generate long lines by limiting the number of machines sent to each precinct.
Touchscreens are vulnerable to denial-of-service attacks and power outages that could prevent voters from voting at all.
Vendors pushing BMDs have disturbingly cozy relationships with many election officials.
Some BMDs test very poorly on the issue of disability access.
BMDs and hybrids cost substantially more than hand-marked paper ballots and scanners, which are more secure.
