Comment :  The main function of the Audit Module is to provide cryptographic protection to both
printed paper ballots and digital votes. This cryptographic protection is based
exclusively on the voter’s verification decision and does not rely on any instruction
given by the DRE or the printer. In other words, the Audit Module protects both the
printed paper ballot and the corresponding digital vote against any manipulation after
the voter has verified and confirmed her vote, thus assuring that both representations
of the vote will coincide and that one can replace the other in case of loss or elimination
(e.g., physical elimination of the printer paper ballot).
Figure 1 summarizes the steps that take place when voting on a DRE-VVPAT system
enhanced with an Audit Module. The addition of the Audit Module, which is transparent
to the voter, allows avoiding having to rely on the DRE and on the physical handling of
the printed ballots.
