I was over it in 2020, I am worried about future elections. Hackers Can Compromise Electronic Voting
By far, the biggest disadvantage of an electronic voting machine is election hacking. As with any electronic device, there is always the risk that someone could illegally alter the results of an election.
This could be done either through physical tampering or a remote attack over the internet. Allowing people to vote using their own devices could pose major risks as well. A malicious agent could change millions of electronic votes undetected. Changing that many paper ballots would be impossible not to notice.
Fraud Is Easier With Electronic Voting
Skeptics of the electronic voting solution claim that fraud can occur digitally. When going to a polling location, voters in most countries are required to provide a form of photo ID to confirm that they are the registered voter they claim to be. While fraud for in-person voting is possible, it requires a false photo ID, which is hard to come across.
With online voting, voter identification would have to occur with some other type of credential. This could include Social Security numbers, dates of birth, driver's license numbers, or some other unique identifier.
The problem with using these types of verification is that anyone who obtains these pieces of information could log in and cast a vote for someone else. If someone obtained a large amount of these identifiers with a data breach, they would be able to cast thousands of fraudulent votes.
Manufacturer Bias Can Influence Votes
Another issue is how electronic voting systems are designed. These would be created and distributed by a private company, who will likely keep their source code locked away. Elections can have a huge effect on business, so company bias becomes an element when purchasing voting machines or systems.
When the government hires a company to implement its electronic voting machines, it's trusting said company to accurately collect and report its votes. There's no guarantee that this will occur, and many believe that no system should ever be implemented if it can't guarantee fair and unbiased voting.
