Anomaly detection in electronic voting systems

Studies have shown that voting error remains a problem with Direct Recording Electronic (DRE) voting machines. DRE's have an advantage over other voting technologies by facilitating ballot verification through review screens. However, results from ballot verification studies have shown that no more than half of study participants notice review screen anomalies (Campbell & Byrne, 2009). This research replicated previous studies on anomaly detection on review screens using a multimodal voting system called Prime III. The results suggest that Prime III facilitates ballot verification and effectively yielded a detection rate of 90%, even without informing participants on the importance of ballot verification.
