The Brazilian Voting System: Electronic ballot boxes are used which bring speed and reliability to the electoral process. Electronic ballot boxes allow polling, storage and counting of votes in hours.
To prove the security that the electronic ballot box offers, the Superior Electoral Court conducts public tests with technicians who are not related to the Court. 200 thousand attempts are made to break the security system of the ballot box per second. So far, none of the attempts has managed to tamper with the system, nor has there been any fraud. This is because the urn is composed of 15 systems and 15 million lines of programming, and, if any of these points are modified, the equipment stops working immediately.
By remote connection, the chances of an attack to succeed are null, since the equipment does not connect to the internet or communication network. The votes are stored in the ballot box, in an encrypted way, and transmitted by a proper system of Electoral Justice. Physically, the polls are sealed and only work on the day and time of the election. In case of tampering, it is possible to view it before voting starts.
With the computerized system, it is not possible to know how each voter votes, since each vote is counted at random and not in the order in which it was entered, precisely to maintain confidentiality. To access the totality of the votes of each ballot box, it is necessary to have a digital signature, to block changes, and access is directly through the exclusive Electoral Justice network and controlled by the Superior Electoral Court.
With this voting system, it is possible to carry out audits on electronic voting machines to attest to security. For this, the Superior Electoral Court conducts the “parallel vote”. In this process, some ballot boxes are drawn by state and some people are selected to vote for a specific candidate in an open way. At the end, a ballot box is analyzed in which it is verified whether the vote given is the same as that registered.
Electronic voting machines have existed in Brazil since the 1996 municipal elections and are considered one of the most automated voting systems on the planet. The degree of reliability is such that ballot boxes developed by the Superior Electoral Court (TSE) have already been loaned to other countries, such as Paraguay, Dominican Republic, Costa Rica, Ecuador, Argentina, Guinea-Bissau, Haiti and Mexico, being a world reference.
