Abstract: As the use of personal information in online social networking seems manifold, including the representation of an individual’s digital persona (social role) and identification, so does the abuse or misuse of the information. The issue of privacy is critically important in this context. Privacy encompasses the right to control information about individuals, including the right to limit access to that information, and the loss of such control often makes us exposed to a bewildering excess of intentional and unintended consequences, including criminal activities ranging from identity theft to online and physical stalking; from embarrassment to price discrimination and blackmailing. In this talk, I will present a novel framework for enabling user-controlled sharing of sensitive personal information for better privacy protection in current online social networks. Specifically, the framework called U-Control is proposed to facilitate digital persona and privacy management (DPPM) in a user-centric way that it can satisfy diverse privacy requirements and specification, and social network environments
