Independent verification systems
Encyclopedia
Independent verification (IV) systems or Independent Dual Verification (IDV) are voting machine
s that produce multiple (at lease two) independent auditable records of votes where the second record is used to check the first. To be considered "independent" at least one of the records must not be editable by the voting machine
and be directly verifiable by the voter. These systems must allow for the multiple records to be able to be cross-checked.
The goal of an IV system is to increase the security, and maintain the integrity of the voting tally. The theory is that any corruption would need to corrupt two separate records to be undetected by an audit.
IV systems can include some Voter Verified Paper Audit Trail
(VVPAT) systems, End-to-end auditable voting systems
, witness systems, and some optical scan voting system

Voter Verified Paper Audit Trail
Voter Verified Paper Audit Trail or Verified Paper Record 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...

End-to-end auditable voting systems
End-to-end auditable or end-to-end voter verifiable systems are voting systems with stringent integrity properties and strong tamper-resistance. E2E systems often employ cryptographic methods to craft receipts that allow voters to verify that their votes were not modified, without revealing which...
