Big data analytics are the cornerstone of numerous online services, underlying tasks such as targeted advertising, personalized recommendations and user profiling. The proliferation of user data collection practices that have enabled such services, along with several recent high-profile privacy breaches, have raised privacy concerns from consumer advocacy groups, regulatory bodies and the public at large. In turn, this has recently spurred an extensive research effort on both theoretical and practical aspects of privacy in big data analytics.

The purpose of this tutorial is to overview this nascent field along three different axes: threats, countermeasures, and user incentives. After a brief introduction of big data analytic techniques, we will cover privacy threats arising from their unfettered application on user data, focusing on case studies of private information leaks. We will then discuss methods for mitigating privacy risks, while still preserving the utility of deployed services. We will cover statistical methods, such as differential privacy, as well as cryptographic techniques applied to inference tasks such as regression and matrix factorization. Finally, we will conclude by discussing how to incentivize strategic users to relax their privacy constraints in return for monetary compensation. We will cover the formal setting of privacy auctions, and overview recent results for such auctions over different regression tasks.
