Privacy-Aware Access Control in Social Networks: Issues and Solutions

Abstract

Abstract Access control in online social networks (OSNs) is becoming an urgent need due to the amount of data managed by social networks and their sensitivity. Performing access control in a social network has many differences with respect to performing access control in a traditional data management system, in terms of both the policy language to support and the reference architecture for access control enforcement. Moreover, it is fundamental to also consider privacy issues connected to access control and to devise appropriate privacy-preserving access control systems. The aim of this chapter is to first discuss which are the requirements of privacy-aware access control to OSN resources and then to review the literature in view of the identified requirements. Finally, the chapter discusses future research directions in the field.KeywordsAccess ControlPolicy LanguageOnline Social NetworkTrust LevelAccess Control PolicyThese keywords were added by machine and not by the authors.
