Abstract:
GPS navigation systems are a potential threat to user privacy in case of curious providers, espionage and many
other aspects. Users tend to place blind trust into GPS applications without realizing the ease at which the GPS
can be spoofed or their position compromised via either the hardware or software. Thus, when a high level
of privacy assurance is required, the GPS should be completely switched off. This paper presents an efficient
method, a smartphone-based alternative solution, for an outdoor offline navigation system, which works in
the absence of GPS, wireless, and cellular signals. The proposed approach exploits the various digital and
mathematical resources present to use DEM data and sensor data to minimize errors in the calculated position
data.
