Efficient service discovery in decentralized online social networks

Decentralized Online Social Networks

Current Online social networks (OSN) are web services run on logically centralized infrastructure. Large OSN sites use content distribution networks and thus distribute some of the load by caching for performance reasons, nevertheless there is a central repository for user and application data. This centralized nature of OSNs has several drawbacks including scalability, privacy, dependence on a...

iSocial: Decentralized Online Social Networks

A taxonomy of decentralized online social networks

Despite their tremendous success, centrally controlled cloud-based Online Social Networks (OSNs) have inherent issues related to user privacy and control. These issues have motivated researchers to make a paradigm shift in the OSN architecture by proposing to replace centrally controlled OSNs with Decentralized OSNs (DOSNs) in a peer-to-peer setting. DOSNs give users more autonomy and the chanc...

Efficient Polling Protocol for Decentralized Social Networks

We address the polling problem in social networks where individuals collaborate to choose the most favorite choice amongst some options, without divulging their vote and publicly exposing their potentially malicious actions. Given this social interaction model, Guerraoui et al. [1], [2] recently proposed polling protocols that do not rely on any central authority or cryptography system, using a...
