Scantegrity - Wikipedia, the free encyclopedia

Scantegrity - Wikipedia, the free encyclopedia:

Scantegrity is a security enhancement for optical scan voting systems, providing such systems with end-to-end (E2E) verifiability of election results. It uses privacy-preserving confirmation codes to allow a voter to prove to themselves that their ballot is included unmodified in the final tally.

Scantegrity II prints the confirmation codes in invisible ink to improve usability and dispute resolution. As the system relies on cryptographic techniques, the ability to validate an election outcome is both software independent as well as independent of faults in the physical chain-of-custody of the paper ballots. The system was developed by a team of researchers including cryptographers David Chaum and Ron Rivest.
