Abstract：
Crowd sourced data collection and data surveillance are gradually integrated into an inseparable part of our society and enable many applications ranging from syndromic surveillance to traffic monitoring. While such individual contributed “Big Data” promises significant economic and social benefits, it also raises serious privacy concerns. In this talk, I will present our PREDICT project for PRivacy Enhancing Dynamic Information Collection and moniToring focusing on two challenges: 1) how to protect location privacy of data contributors for crowd sourced data collection, and 2) how to protect privacy of individual data subjects when sharing the collected data for real time monitoring and analytics. I will present several novel solutions for spatiotemporal data monitoring with differential privacy followed by empirical studies on real-world data, demonstrating the feasibility of the approach as well as some open challenges.
