Talk Title: Privacy-Preserving Data Sharing and Analytics with Differential Privacy
Abstract: While Big Data promises significant value, it also raises increasing privacy concerns. In this talk, I will describe our efforts towards a comprehensive privacy-preserving data sharing and analytics framework. Following an overview of the framework, we discuss two settings based on state-of-the-art differential privacy techniques: 1) aggregated data sharing for data mining and analytics, and 2) individual location sharing for location based services. For aggregated sharing, I will present several technical solutions for handing different types of data including sequential and time series data, using medical and spatiotemporal data mining applications. For individual data sharing, I will present our approach towards a rigorous and customizable privacy notion extending the differential privacy framework for location protection, with location based applications such as nearest POI search and geospatial crowdsourcing.
This lecture satisfies requirements for CSCI 591: Research Colloquium. Please note, due to limited capacity in SOS B2, seats will be first come first serve.
