Notes
The DHS 2025 AI Use Case Inventory (entry DHS-135, as consolidated by the Office of Management and Budget) lists 'Low Probability of False Alarm (Low-Pfa) Algorithm for on-person screening.' as deployed. The entry says the algorithm shows threat locations as a box on a representative human figure for the operator, aiming to cut alarm and touch rates by 50%. It gives an operational date of 12 December 2022 and classes the use as high-impact. The inventory separately lists, as pre-deployment and high-impact, further automated target recognition developments for advanced imaging scanners in standard screening (DHS-131), meant to increase detection and reduce false alarms so that officers no longer need to view the scanner images.
