TSA has implemented strict measures to protect passenger privacy, which is ensured through the anonymity of the image. Automated target recognition software detects any metallic and non-metallic threats concealed under clothing by displaying a generic outline of a person on a monitor attached to the advanced imaging technology unit highlighting any areas that may require additional screening. The generic outline of a person will be identical for all passengers. If there isn’t an alarm, an “OK” appears on the screen with no outline.
