Understanding Vulnerabilities of Location Privacy Mechanisms against Mobility Prediction Attacks
Zohaib Riaz, Frank Dürr, Kurt Rothermel · 2017
In today's online social networks such as Facebook, users increasingly share their location information as a popular type of personal information. However, since location data can leak privacy-sensitive information about individuals such as the type of places they like to visit, a number of location obfuscation mechanisms have been proposed to avoid such disclosure. These mechanisms publish bigger regions containing the actual user location in order to make it imprecise. Thus an attacker may find it hard to precisely locate the user in a privacy-sensitive place such as a hospital.
