Right so the problem is that you want to be able to verify your vote, but you don't want anyone else to be able to verify your vote. Your SSN is semi-public and lots of people likely already know it (e.g. employer, who is also a prime candidate to try to buy/coerce your vote). But even with a private key, you have to assume you can be coerced into giving it up.

So any system that allows you to verify a vote needs to come not only with a way for you to validate it, but also with deniability built in. Because if it's not then you can a) sell your vote or b) be intimidated into showing how you voted (which may result in a firing/beating if you did it wrong).

There are, I think, one or two ways to achieve this, but it's a non-trivial problem.
