The problem of addition (or deletion) of votes is solved by having a paper pollbook to go with an electronic pollbook, plus doing reconciliation.
Election integrity is about finding all the attacks that can reasonably be expected, and detecting or -even better- preventing them. But it's a tougher problem than this one-sentence summary makes it sound.
Ever heard of "voting the graveyard"?
A paper trail is not a guarantee of electoral integrity. There is always a rough spot when your ideal election system meets the messy real world.
Paper voting at least has a trail. Electronic voting leaves no trail at all.
Re: "voting the graveyard" there are following ways to prevent it:
An election monitor can manually count people coming to the polling station and compare it to the number of ballots taken out of the box. Monitor can observe how those votes are counted, and get a signed document with results. After counting the votes across the country, he can compare his paper document with official published results, filtering them by his polling station. Every step is verifiable.
Also, every voter must leave a signature. Signatures also can be verified.
