| Research Abstract |
The rise of location-sharing services on a number of mobile platforms have recently opened up the possibilities of sharing location information with other users. However, location sharing raises significant privacy concerns because location data (e.g., visiting a hospital) can be used to infer a user's personal activities. Since it is often possible to infer a user's suppressed location data from disclosed public locations considering strong spatial and temporal correlation among them, we develop a new access-control scheme against such inference attacks and conduct experiments with a real location dataset to show the effectiveness of our proposed method.
