Brazil’s rapid election count, utilizing a digitally-checked system with biometric verification and extensive audits, has drawn attention for its security. Analysts suggest it could offer a model for the US midterms, following challenges to the integrity of the Brazilian system by former President Bolsonaro.
What happened
- In Brazil, approximately 125 million citizens voted on October 4th using machines that print no paper ballots.
- The system, in place for over three decades, relies on fingerprint verification for voter identification and is audited by numerous parties, universities, and watchdogs.
- Eleven days after the election, Flavio Bolsonaro, son of former President Jair Bolsonaro, secured first place with 47.03% of the vote, while Luiz Inacio Lula da Silva received 45.16%. The system’s robustness is attributed to its disconnection from the internet, open-source software, and automated tallying process.
- Karina Stange Calandrin, a political scientist, highlighted the system’s combination of electronic voting, locally stored voter eligibility data, and automated tallying as exceptionally secure.
- The Superior Electoral Court (TSE) utilizes a process where randomly drawn machines feed paper ballots, and every machine prints its tally with a QR code for public verification.
- Eleven days before the US midterms, the Brazilian system is being considered as a potential model for enhanced voting security in the United States.
- The TSE’s digital signature system confirms the results produced by the machines, and the system has faced scrutiny from former President Bolsonaro, who spent years attacking its credibility.
- The system’s security has been repeatedly validated by external audits and evaluations, with no evidence of tampering or malicious intent found.
