  To protect the location of camera trap data containing sensitive, high-target
species, many ecologists randomly obfuscate the latitude and longitude of the
camera when publishing their data. For example, they may publish a random
location within a 1km radius of the true camera location for each camera in
their network. In this paper, we investigate the robustness of geo-obfuscation
for maintaining camera trap location privacy, and show via a case study that a
few simple, intuitive heuristics and publicly available satellite rasters can
be used to reduce the area likely to contain the camera by 87% (assuming random
obfuscation within 1km), demonstrating that geo-obfuscation may be less
effective than previously believed.
