  In this work, we present CCTV-Exposure -- the first CCTV-aware solution to
evaluate potential privacy exposure to closed-circuit television (CCTV)
cameras. The objective was to develop a toolset for quantifying human exposure
to CCTV cameras from a privacy perspective. Our novel approach is trajectory
analysis of the individuals, coupled with a database of geo-location mapped
CCTV cameras annotated with minimal yet sufficient meta-information. For this
purpose, CCTV-Exposure model based on a Global Positioning System (GPS)
tracking was applied to estimate individual privacy exposure in different
scenarios. The current investigation provides an application example and
validation of the modeling approach. The methodology and toolset developed and
implemented in this work provide time-sequence and location-sequence of the
exposure events, thus making possible association of the exposure with the
individual activities and cameras, and delivers main statistics on individual's
exposure to CCTV cameras with high spatio-temporal resolution.
