Nowadays Social Network Sites (SNSs) have integrated
into our daily life and become an integral part of users’ social life.
The number of users of SNSs has dramatically increased
in recent years, together with the huge revelation of
information. Although SNSs vary in usage patterns, design
and so forth, SNS share the main characteristic: they provide
users with chance of creating their own profile – which can be
considered as their self-presentation, network-building,
sharing interest and also the platform to express themselves.
On the one hand, it bring to our modern life another platform
for maintaining current relationships and starting seeking for
new friends and communities. On the other hand, with the
disclosure of profile information, also the revelation of other
personal data to the friends or unknown audiences, it raises the
concern of privacy.
