Abstract

An information barrier for determining whether a person is concealing a dangerous weapon without exposing any sensitive or private information about the subject is disclosed. Within an enclosure, detector means obtain images of individuals, including images of concealed dangerous items, and output the images. Computing means receive the images for separating the concealed dangerous items from the personal image, and output a signal if an image of the concealed dangerous items is located, and display means output a non-sensitive indication of whether the concealed dangerous items have been detected.

display means for outputting a non-sensitive indication of whether said concealed dangerous items have been detected.

2. The information barrier described in claim 1, wherein said computing means contains only volatile memory.

3. The information barrier described in claim 2, further comprising a door in said enclosure, said door having an interlock to interrupt electrical power to said computing means upon the opening of said door.
