Researchers showed that "anonymized" voter registration records become identifiable when cross-referenced with other public datasets, a vulnerability that persists regardless of what information states withhold. Voter rolls are among the most accessible public records in the U.S., making them a reliable starting point for foreign intelligence services or domestic bad actors to build dossiers on specific individuals. The finding exposes a flaw in the American transparency model: the assumption that limiting any single dataset protects anonymity collapses once adversaries combine multiple sources.
