Abstract: Examples provide a system for score-based verification of basket contents. A user trust score is generated based on the user's transaction history, item selection area data, and trust rules. The trust score provides a base value which is decremented by a predetermined amount based on behavior-related triggers detected as the user scans items during item selection to generate a temporary per-basket verification score. The triggers include a threshold number of item voids, a threshold number of unknown items scanned, and/or a threshold time elapsed after scanning an item. If the per-basket verification score is greater than or equal to a minimum threshold score, the basket is approved for check-out. If the per-basket verification score is below the threshold value, the basket of items is selected for a partial verification of the contents of the basket. If the partial verification fails, a comprehensive verification of the basket contents is initiated.
