Survey on Decentralized Online Social Networks
Résumé
Because of growing popularity of Online Social Networks (OSNs) and huge amount of sensitive
shared data, preserving privacy is becoming a major issue for OSN users. While most
OSNs rely on a centralized architecture, with an omnipotent Service Provider, several
decentralized architectures have recently been proposed for decentralized OSNs (DOSNs).
In this work, we present a survey of existing proposals. We propose a classification of previous
work under two dimensions: (i) types of approaches with respect to resource provisioning
devices and (ii) adopted strategies for three main technical issues for DOSN
(decentralizing storage of content, access control and interaction/signaling). We point
out advantages and limitations of each approach and conclude with a discussion on the
impact of DOSNs on users, OSN providers and other stakeholders
