Abstract: These are most exciting times to be a privacy researcher since, in today's hyper-networked world with global data flows, almost all major business and technology trends, then be it Big Data, Cloud Computing, Mobility, BYOD, or Internet of Things, require deep privacy underpinnings. So there is ample opportunity to invent and innovate.

In this talk we begin by observing that security and privacy are fundamentally different notions. While security paradigm assumes a clear separation between users and attackers, in privacy paradigm users are attackers too, depending on the use intent, and therefore security controls such as standard encryption-based mechanisms do not suffice!

Next we discuss the major goal of data privacy research, that is, to find the right balance between the two extremes of fully disclosed and completely withheld data that preserves both data privacy and its utility, and thus enable data sharing.

We then deliberate on two orthogonal efforts towards privacy formalization, namely, k-anonymity model and differential privacy. Both of them are not full proof, and yet are good frameworks for enabling fool proof data sharing in diverse scenarios.

Finally we close the talk with a brief overview of our work and description of some privacy problems that could have both practical relevance and theoretical meat.

Duration : 60 minutes (including audience Q&A)
