Public election records combined with artificial intelligence risk exposing individual secret ballots
Research suggests that accessible voting records could allow algorithms to connect people directly to their cast ballots.

An academic at Princeton determined that artificial intelligence tools can process public election files to associate individual voters with their specific choices. Ballots are designed to protect voter privacy from public officials, neighbors, and relatives, but cross-referencing available administrative records with modern computational methods undermines that separation.
The findings indicate that information open to public inspection contains enough overlapping data points for automated systems to reconstruct choices made in private. The practical extent of the vulnerability, the specific algorithms involved, and the response from election authorities remain unclear.
