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.
