Multi-user Itinerary Planning for Optimal Group Preferencese one approximate solution with bounded approximation ratio and one exact solution which computes the optimal itinerary by exploring a limited number of paths in the road network. In addition, an effective compression algorithm is developed to reduce the size of the network, providing a significant

On Privacy in Spatio-Temporal Data: User Identification Using Microblog Datat prolific 500 of these users. Furthermore, it can correctly identify more than 50% of any users by using three observations of these users, rather than their whole location trace. This alarming result shows that spatio-temporal data is highly discriminative, thus putting the privacy of hundreds of
