DHS/S&T/PIA-016 Critical Infrastructure Change Detection


The Critical Infrastructure Change Detection (CICD) program (also known as the Wide Area Surveillance program) is a DHS Science and Technology (S&T) research program that is examining novel technical approaches to provide wide area surveillance and change detection capabilities to protect the Nation's critical infrastructure. S&T proposes to test a high resolution, 360 degree field-of-view video system that will accommodate multiple simultaneous users and also have change detection and tracking capabilities. A PIA is being conducted because system demonstrations will be performed in public areas within major US cities and will involve capturing images of persons and textual information in the public space.
