报告摘要：In recent years, social network research has advanced significantly. People perceive the Web increasingly as a social medium that fosters interaction among people, sharing of experiences and knowledge, group activities, community formation and evolution. This has led to a rising prominence of social network analysis and mining in academia, politics, homeland security and business. However, growing popularity of on-line social networking, not only brings the convenience of information sharing but also concerns of privacy breaches, as sensitive information, through links and inferences, individual’s identity, health, financial status, political affiliations, etc, might be disclosed. In order to preserve privacy of users, anonymization is required prior to attempts to make the data more widely available to public. In this talk, we will first review the basic concepts of social networks analysis and then concentrate on introducing recent studies in privacy preservation on published data such as relational, transactional, social network data, and spatial data.
