This synthesis lecture provides a survey of work on privacy in online social networks (OSNs). This work encompasses concerns of users as well as service providers and third parties. Our goal is to approach such concerns from a computer-science perspective, and building upon existing work on privacy, security, statistical modeling and databases to provide an overview of the technical and algorithmic issues related to privacy in OSNs. We start our survey by introducing a simple OSN data model and describe common statistical-inference techniques that can be used to infer potentially sensitive information. Next, we describe some privacy definitions and privacy mechanisms for data publishing. Finally, we describe a set of recent techniques for modeling, evaluating, and managing individual users' privacy risk within the context of OSNs.

Social Capital and Strategy Effectiveness: An Empirical Study of Entrepreneurial Ventures in a Transition Economy

Although new ventures’ competitive positioning and their founders’ social networks are both recognized as important in the context of transition economies, not much is known about their multiplicative effect on performance. We build on the strategic management literature and social network theory to develop theoretical predictions about the role of competitive strategies and social capital for entrepreneurial performance. These are tested with survey data from Bulgaria. We find that both the venture’s competitive strategic positioning and the founder’s networking positively influence performance. The hypothesized moderating effect of networking for the relationship between differentiation strategy and performance received only tentative support. Contrary to expectations, we find a negative moderating effect of networking for the relationship of cost leadership with performance. These results suggest that the entrepreneur’s network plays a role in shaping how strategies influence performance by possibly upholding differentiation and deemphasizing cost leadership strategy. Implications for managerial practice and public policy are discussed.
