Software Independence

This section maps to Requirement 9.1.1-A.2

VxSuite provides software independence through a paper ballot based voting system:

• Voters mark pre-printed paper ballots by hand. Since no software is involved, this phase is naturally software independent.

• Ballot scanners, both precinct and batch, produce cast-vote records (CVRs) that are suitable for running post-election audits. Thus, if software on VxSuite scanners is modified in such a way as to affect the way ballots are interpreted, a post-election audit, such as a risk-limiting audit, can be used on the produced cast-vote records to ensure that the outcome is true to the intent of the voters as recorded on the paper.
