Abstract：
With the increasing prevalence of various digital devices and computing services, we leave a large amount of digital traces in our daily lives. Such digital traces are valuable sources for diverse data analysis and data mining tasks. Yet, privacy threats in the course of data sharing have been a major impediment to the advancement of these tasks. In this talk, we will briefly review the technical efforts made by the data privacy community in the past fifteen years. Driven by various privacy attacks, privacy researchers have proposed a series of privacy models, such as k-anonymity, l-diversity and t-closeness, to define individual privacy from a technical perspective. Unfortunately, this line of privacy models is vulnerable to an attacker’s background knowledge. In recent years, differential privacy has emerged as the standard privacy notion that provides rigorous privacy guarantees independent of an attacker’s background knowledge. We will discuss the definition and basic properties of differential privacy, the challenges of applying differential privacy to social network data, and two preliminary solutions towards differentially private social network data publishing.
