讲座摘要:
Spatial trajectory data have been collected extensively from vehicles, mobile phones, various types of monitoring devices and social media applications. In this talk, we will discuss the two sides of a coin: how to link moving objects accurately and efficiently based on their historical trajectories to improve data utility, and how to protect user privacy by modifying data such that moving objects cannot be linked together. In addition to discussing different approaches to achieve utility and to protect privacy for spatial trajectories, we will also discuss possible trade-offs between these two objectives in the context of contact tracing.
