  - 24/7 data availability;
  - data transfer;
  - data loading and processing delay;
  - data encryption;
  - data caching;
  - social network relationship management.

- 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.
