When you vote on an electronic machine, why not have it give you a printout with a unique number (maybe a checksum) just for you and a list of how you voted. Then when all the voting is done, the list of everyone's unique number and how they voted is made public. That way everyone can verify that their vote has been correctly recorded. If there is a mistake they can report it and edit it (within so many days) if you just entered something wrong or alert the authorities if it doesn't match your printout. And the list could have a checksum to prove that copies of it havn't been altered.

No, because that would be illegal. Do you really think that sort of thing would be widespread or even a greater threat that vote machine manipulation?
