Many consumers today willingly give up their current location information in exchange for location-based social services. This development poses great privacy risks. PALS aims at designing, implementing, and evaluating novel methods and tools to facilitate the privacy-aware sharing of location data with friends, strangers, and operators. Its goal is to offer a decentralized approach that supports all needed features of location sharing systems without the need to centrally collect location data.
Duration of the project: April 2010 – August 2013
