When using a centralized communications service, such as Facebook,
the level of security and privacy we can achieve is that the postman carries
non- transparent sacks. The business model of most such services is to read
peoples postcards to better profile their interests and thus deliver better suiting
advert- ising. Here, third parties cannot directly see who is communicating with
whom. They can only see that something goes to and from the service.
However, all information is available internally to the service. This means
that there are ways of learning this, for example through PRISM (Greenwald
and MacAskill
2013) of the US National Security Agency (NSA).

%Which kind of third parties are these, when compared to the
%case of e-mail? Advertisers? Or other parties? And
%can advertisers read the content in e-mail systems? Google
%lets them advertise on keywords, but not read the mail
%itself for instance. Or hackers?

This comment was treated in another way. It's an interesting problem to
look into though, but maybe it's a paper in itself.
It's now moved to issue #33.
