A trajectory protection method based on differential privacy and semantic attributes
Abstract:With the popularity of smart wearable devices, Location-Based Services (LBS) have been widely applied. However, LBS generates thousands of trajectories, which may potentially leak personal information. To address such privacy concerns, it's often necessary to protect users' trajectory data. Existing differential privacy schemes commonly used for trajectory protection suffer from inefficiency and lack support for semantic attributes. To tackle these issues, this paper proposes a trajectory protection method bas… Show more
