Abstract
A privacy preserving geofencing system and method are disclosed. The method includes receiving a current location data of a vehicle. The current location data is homomorphically encrypted through a homomorphic encryption technique. The method further includes randomly generating at least two secure values corresponding to the current location data of the vehicle. The method further includes combining the at least two secure values with the current location data of the vehicle. The method further includes sharing a combination of the current location data and the at least two secure values to a computing server. The method further includes computing the current location data of the vehicle obfuscated with the at least two secure values to obtain a computed result. The computed result determines if the vehicle is within a predefined geofencing region based on one or more geofencing criteria.
