A Framework for Enabling User-Controlled Persona in Online Social Networks

Abstract

Abstract-As the use of personal information in social network sites seems manifold, including the representation of an individual's digital persona (or social role) and identification, so does the abuse or misuse of the information. The issue of privacy is critically important in this context. In this paper we 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. We discuss the design of a security system based on the proposed framework. Finally we discuss a proof-of-concept implementation, along with performance evaluation.

“…The basic notion of user-centricity is to give users, not organizations, a larger degree of control over personal information, and it has been practiced widely in the federated identity management (FIM) domain to provide a better mech-Digital Object Identifier: 10.4108I/CST.COLLABORATECOM2009.8401 http://dx.doi.org/10.4108/ICST.COLLABORATECOM2009.8401 anism for upholding user privacy over identity attributes [3], [4]. In order to support the notion of user-centricity in existing online SN systems, we identified three fundamental services, which are identity attribute management, privacy preference management, and selective attribute sharing [5]. Further we proposed a framework called If-Control that enables those services, as shown in Figure 1.…”
