Comment :  This article presents an innovative solution developed by Scytl Secure Electronic
Voting to complement and improve VVPAT solutions, providing them with enhanced
security and accessibility. Scytl’s solution is based on a simple Audit Module, which
can be easily integrated with any DRE and with any VVPAT solution. This Audit Module
acts as a neutral auditing element, which monitors the verification process and
provides its own digital signature on both printed paper ballots and digital votes, thus
assuring that both representations of the same 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).
The addition of the Audit Module to DRE-VVPAT systems allows (i) to prevent the
addition of bogus ballots without running the risk of invalidating valid votes as a result
of the accidental or voluntary generation of incorrect digital signatures on the printed
paper ballots, (ii) to prevent the elimination or alteration of valid votes by providing an
accurate recovery mechanism, (iii) to provide election authorities with accurate
mechanisms to determine the correct results in case of discrepancies between the
results from the DRE and the count of paper votes, and (iv) to provide accessibility to
the VVPAT solution for blind and visually impaired voters.
