Differential privacy has become an important research area since the first publication on information
disclosure in 2006. Since then, extensive work has been done to develop this new concept because
it constitutes a rigorous and provable privacy notion that can be implemented in various research areas.
In this presentation, I will start with introducing the basic concept of differential privacy and several
scenarios on which it can be used for data release and analysis. Based on these scenarios, I then focus
on the challenge of the privacy preserving in Big Data. Finally, I will present some popular applications
of differential privacy and envisage future research directions. The talk will be based on our following
publications:

Dr Tianqing Zhu received her BEng and MEng degrees from Wuhan University, China, in 2000 and 2004,
respectively, and a PhD degree from Deakin University in Computer Science, Australia, in 2014. Dr Tianqing
Zhu is currently a continuing teaching scholar in the School of Information Technology, Deakin University,
Melbourne, Australia. Before joining Deakin University, she served as a lecturer in Wuhan Polytechnic
University, China from 2004 to 2011. Her research interests include privacy preserving, data mining and
network security. She has won the best student paper award in PAKDD 2014 and was invited to give a
tutorial on differential privacy in PAKDD 2015.
