tekinha | 11 years ago | on: Fraud possible in Brazil's e-voting system
The Brazilian machines, which are based on the Direct Recording Electronic (DRE) model, do not produce a physical proof that the vote has been recorded. This means there is a constant danger of large-scale software fraud, as well as other non-technical tampering that could be perpetrated by former or current electoral justice staff and go totally undetected, according to Aranha.
