Uh, no. Computing is the absolute opposite of security. Doubly so for anything networked.
If you want to take anything secure, and make it unsecure, simply transform it from paper, and put it on a computer. Bam!
Paper is millions of times more secure than a computer. No piece of software is ever, ever secure. There are always, literally always thousands and thousands of hardware, and software vulnerabilities just waiting to be exploited.
Compared to any form of computerized voting, ballots are insanely secure.
But what you're missing here is process. Paper voting has been around for a very, very long time. Process is well established, very simple to do, but it seems the US is always changing how to count, how to tally, and more.
But, to pause and take a step back ... I'm not sure how you think adding a computer to the mix, improves auditing. The entire point of a voting system, is that your vote remains anonymous. Therefore, the device or method that records your vote? Must not ever ever be assigned to you. And this also includes any form of anonymization.
This has also been handled for a very, very long time. Again, by process.
I wonder, how many years have you (or others advocating a computer inserted into the voting process), studied in depth the chain of trust used with paper ballots? Or precisely how ballots are counted? Or, even months? Weeks?
All I know is that when I researched paper ballots here in Canada, every aspect I could think of was covered. And that's what you'd expect, from a voting process that evolved over literally hundreds of years, with deep thought put into each voting cycle.
