Two
tales of privacy in online social networks
ABSTRACT:
Privacy is one of the friction points that emerges when
communications get mediated in Online Social Networks (OSNs). Different
communities of computer science researchers have framed the ‘OSN privacy
problem’ as one of surveillance, institutional or social privacy. In tackling
these problems they have also treated them as if they were independent. We
argue that the different privacy problems are entangled and that research on
privacy in OSNs would benefit from a more holistic approach. In this article,
we first provide an introduction to the surveillance and social privacy
perspectives emphasizing the narratives that inform them, as well as their
assumptions, goals and methods. We then juxtapose the differences between these
two approaches in order to understand their complementarity, and to identify potential
integration challenges as well as research questions that so far have been left
unanswered.
EXISTING SYSTEM:
Researchers from different sub-disciplines in
computer science have tackled some of the problems that arise in OSNs, and
proposed a diverse range of “privacy solutions”. These include software tools
and design principles to address OSN privacy issues. Each of these solutions is
developed with a specific type of user, use, and privacy problem in mind. This
has had some positive effects: we now have a broad spectrum of approaches to
tackle the complex privacy problems of OSNs. At the same time, it has led to a
fragmented landscape of solutions that address seemingly unrelated problems. As
a result, the vastness and diversity of the field remains mostly inaccessible to
outsiders, and at times even to researchers within computer science who are
specialized in a specific privacy problem.
DISADVANTAGES
OF EXISTING SYSTEM:
For example, consider surveillance and social
privacy issues. OSN providers have access to all the user generated content and
the power to decide who may have access to which information. This may lead to
social privacy problems, e.g., OSN providers may increase content visibility in
unexpected ways by overriding existing privacy settings. Thus, a number of the
privacy problems users experience with their “friends” may not be due to their
own actions, but instead result from the strategic design changes implemented
by the OSN provider.
Another major problem is that users encounter great
difficulties to effectively configure their privacy settings.
PROPOSED SYSTEM:
We distinguish three types of privacy problems that researchers
in computer science tackle. The first approach addresses the “surveillance
problem” that arises when the personal information and social interactions of
OSN users are leveraged by governments and service providers. The second approach
addresses those problems that emerge through the necessary renegotiation of
boundaries as social interactions get mediated by OSN services, in short called
“social privacy”. The third approach addresses problems related to users losing
control and oversight over the collection and processing of their information
in OSNs, also known as “institutional privacy”
ADVANTAGES
OF PROPOSED SYSTEM:
In this article, we argue that these different
privacy problems are entangled, and that OSN users may benefit from a better integration
of the three approaches.
The goal of PETs in the context of OSNs is to enable
individuals to engage with others, share, access and publish information
online, free from surveillance and interference. Ideally, only information that
a user explicitly shares is available to her intended recipients, while the
disclosure of any other information to any other parties is prevented.
