Location Privacy Challenges and Solutions. Part 1: GNSS localization

Positioning (or localization) is a key component in many wireless devices and a key enabler and optimizer of many mobile applications, including transportation, smart cities, and ambient assisted living. For example, mobile wireless devices relying on a location component can be used as mobile assistants and wearable devices for the elderly, sick, or disabled, for traffic and environment monitoring, for green mobile crowd sensing, in crisis scenarios, for wildfire risk prediction, etc. (see I. Maglogiannis et alia and L. Skorin-Kapov et alia in Additional Resources). When the time dimension is added to the positioning information, we talk about user or device tracking.
