Location privacy is a major concern for mobile users. This work provides the first experimental evidence about the effectiveness of context-based identifier-change mechanisms in protecting users’ location privacy in currently deployed wireless systems. By means of simple probabilistic tracking algorithms in a real mobile network setting, we show that these techniques are largely ineffective in protecting location privacy of mobile users.
