VVPAT
is the acronym of “Voter Verified Paper Audit Trail” and VVBP is the acronym of “voter verified paper ballot“. The terms are equivalent and refer to a kind of “vote receipt” printed by an electronic voting machine that shows the elector his/her vote as it is being entered into the electoral system. The voter must be required to perform an action that confirms that their choices have been recorded correctly on the paper, hence making it a verified (rather than just “verifiable”) ballot in a legal sense. The VVPAT/VVBP is kept by the election official, as the record of votes cast, for audit and recount purposes. Verification of a small percentage of VVPAT should to be activated when elections are close.

Voter-verified paper audit trail (VVPAT) or verified paper record (VPR) is a method of providing feedback to voters using a ballot less voting system. A VVPAT is intended as an independent verification system for voting machines designed to allow voters to verify that their vote was cast correctly, to detect possible election fraud or malfunction, and to provide a means to audit the stored electronic results.

The VVPAT offers some fundamental differences as a paper, rather than computer memory, recording medium when storing votes. A paper VVPAT is readable by the human eye and voters can directly interpret their vote. Computer memory requires a device and software which potentially is proprietary. Insecure voting machine records could potentially be changed quickly without detection by the voting machine itself. It would be more difficult for voting machines to corrupt records without human intervention. Corrupt or malfunctioning voting machines might store votes other than as intended by the voter unnoticed. A VVPAT allows voters the possibility to verify that their votes are cast as intended and can serve as an additional barrier to changing or destroying votes.
