Carousel voting

A scheme in which voters carry out a pre-marked ballot and return a blank one, letting an organiser verify each vote — an attack on ballot secrecy used to enforce vote buying.

Secret ballot

The guarantee that no one can link a voter to their choice — the precondition for free voting, and what vote buying and voter intimidation both attack.

Ballot secrecy breach

Any arrangement that lets a third party learn how an individual voted — including photographed ballots, transparent envelopes and overly small reporting units.
