—In voting, the notion of receipt-freeness has been proposed to express that a voter cannot gain any information to prove that she has voted in a certain way. It aims to prevent vote buying, even when a voter chooses to renounce her privacy. In this paper, we distinguish various ways that a voter can communicate with the intruder to reduce her privacy and classify these according to their ability to reduce the privacy of a voter. We develop a framework combining knowledge reasoning and trace equivalences to formally model voting protocols and define vote privacy for the voters. Our framework is quantitative, in the sense that it defines a measure for the privacy of a voter. Therefore, the framework can precisely measure the level of privacy for a voter for any of the identified privacy classes. The quantification enables the framework to capture receipts that reduce, but not nullify, the privacy of the voter. This has not been identified and dealt with by other formal approaches...
