Vis-a-Vis DOSN

A Vis-a-Vis DOSN is a Decentralized Online Social Network that is a decentralized cloud system that runs on independent and personal virtual individual servers.

• AKA: Vis-à-Vis.
• Context:
  • It was first developed by Shakimov et al. (2011).
  • It can include the following DOSN's services:
    • data management by the users;
    • 24/7 data availability;
    • data transfer;
    • data loading and processing delay.
• Example(s):
  • ...
  • …
• Counter-Example(s):
  • DECENT DOSN,
  • PeerSoN,
  • Persona OSN,
  • SafeBook,
  • PrPl,
  • SlopPy,
  • SuperNova.
• See: Decentralized P2P-based Online Social Network, Decentralized Network, Decentralized Computing System, Decentralized Application, Distributed Network, Decentralized Clinical Trial, Online Social Network, Amazon Elastic Compute Cloud (EC2), Rackspace Cloud Server.

  • QUOTE: The results of the comparison are summarized in Fig. 1. The solutions of the investigated concepts of PeerSoN (Buchegger et al., 2009), Priv.io (Zhang and Mislove, 2013), Safebook (Cutillo et al., 2011), and SuperNova (Sharma & Datta, 2012) are based on a peer-to-peer approach. The concepts PrPl (Seong et al., 2010), SlopPy (Gambs & Lolive, 2012), and Vis-à-Vis (Shakimov et al., 2011) are based on distributed applications and on server solutions as well as cloud solutions that are self-managed by the user. As a common ground of these concepts, all parties are expected to run and manage their own cloud system. The eight already mentioned systems will now be explained shortly and examined with regard to their currently unsolved problems.

  • QUOTE: Given the importance of OSNs in users' lives and the sensitivity of the data users place in them, it is critical to limit the privacy risks posed by today’s OSNs while preserving their features. To address this challenge, we have developed a general framework for managing privacy-sensitive OSN data called Vis-a-Vis. Vis-a-Vis can interoperate with existing OSNs and is organized as a federation of independent, personal Virtual Individual Servers (VISs). A VIS is a virtual machine running in a paid cloud-computing utility such as Amazon Elastic Compute Cloud (EC2) or Rackspace Cloud Servers. Utilities provide better availability than desktop PCs and do not claim any rights to the content placed on their infrastructure. Thus, just as cloud utilities are already trusted with many enterprises’ intellectual property, utility-based VISs store their owner’s sensitive data and arbitrate requests for that data by other parties.
