Location spoofing attack detection with
pre-installed sensors in mobile devices The University of Hong Kong, Hong Kong {skwong, smyiu}@cs.hku.hk Abstract The Global Positioning System (GPS) plays an
important role in many industries nowadays. It provides a simple and
convenient way for users to locate their position on the Earth. Since the
radio wave signal from the GPS Satellite propagates through space and air, it
can be easily altered by location spoofing attack (LSA), which is a signal
interference on legitimate GPS signal in order to transmit inaccurate GPS
coordinates to the target. In recent years, the term ’location spoofing’ can
also refer to the act of false reporting on one’s GPS location to other
location-based applications. Not many research works have been proposed
against the latter problem and none of them provide a good solution on
detecting location spoofing within local areas. In this paper, we clarify and
differentiate between these two kinds of location spoofing attacks to avoid
ambiguity in future research work. We proposed a behavioral detection method
making use of the gyroscope and accelerometer commonly equipped in most
mobile devices. We verify the genuineness of the GPS data by comparing the
travel direction with the facing direction deduced from the orientation data
provided by the gyroscope. We further examine the GPS data with the step
count provided by the accelerometer to see whether the step length of the
travel aligns with the average adult step length. Experiment results show
that our proposed methodology can efficiently differentiate between normal
and spoofing travels with large deviation on travel direction and step
length. We also show that our method is simple to implement in practical
situations. Keywords: Location Spoofing, GPS Spoofing,
