A Survey on Privacy in Decentralized Online Social Networks

Decentralized Online Social Networks (DOSNs) have recently captured the interest of users  because of the more control given to the end users over their shared social contents. Indeed, user privacy issues related to the centralized Online Social Network (OSN) services (such as Facebook or Google+) does not apply in the case of DOSNs because of the absence of the centralized service provider. However, these new architectures have motivated researchers to investigate new privacy solutions that allow DOSN's users to protect their contents by taking into account the decentralized nature of the DOSNs platform. In this survey, we provide a comprehensive overview of the privacy solutions adopted by DOSNs and  compare them by exploiting several criteria. After presenting the differences that the proposed DOSNs present in terms of provided services/architecture,  we identify, for each DOSN, the privacy model used to define the privacy policies and the mechanisms for the management of the privacy policy  (i.e., initialization and modification of the privacy policy).In addition, we evaluate the overhead introduced by security mechanisms adopted for privacy policy managements by discussing their advantages and drawbacks.
