With the increasing popularity of GPS-enabled handheld devices, location based services (LBS) have access to accurate location information, raising serious privacy concerns for end users. Trying to address these issues, the notion of geo-indistinguishability was recently introduced, protecting privacy by reporting to the LBS only a noisy version of the user's location.Standard geo-indistinguishability works well in the case of a sporadic use, however, under repeated use over time, constantly applying noise leads to a quick loss of privacy.In the first part of this thesis we show that correlation in the trace can be in fact exploited through a prediction function that tries to guess the new location reducing the number of sanitized positions...
