Use of threat image projection (TIP) to enhance security performance

Threat Image Projection (TIP) is a software system that is used at airports to project images of threat items amongst the passenger baggage being screened by X-ray. The use of TIP is becoming more widespread and is increasingly being included as part of security regulation. This is due to its purported benefits of improved attention and vigilance, and increased exposure to threat items that are linked to improvements in threat detection performance. Further, the data collected by the TIP system can be used to assess individual performance, provide feedback to screeners, and tailor training to specific performance weaknesses; which can generate further performance improvements. However, TIP will only be successful in enhancing security performance if it is used and managed effectively.
