Abstract
The linkability of trajectory data based on similarities to candidate trajectory data is measured and quantified as describer herein. Methods may include: receiving a set of probe data points defining a target trajectory from a probe apparatus; characterizing the trajectory based on features of the target trajectory; identifying a plurality of candidate trajectories sharing at least some features with the target trajectory; calculating, for each of the plurality of candidate trajectories, a similarity score with respect to the target trajectory; calculating a privacy score representing a likelihood of identifying the probe apparatus from the target trajectory based on a number of trajectories in the plurality of candidate trajectories and their respective similarity score; and providing information associated with the target trajectory for location-based services in response to the privacy score satisfying a predetermined value.
