Is there a way for us to remove the anonymity of
users in social media sites such as Facebook?



Facial Recognition in Use



Carnegie Mellon University conducted experiments to see if an
individual could be identified based on the availability of
select information, both online and offline.


They searched public profile images from online social networks
and compared them to dating sites to determine how accurate the
software was in identification


They collected images of consenting students walking on a
campus, and compared those to Facebook. Students provided
some information and were asked to identify themselves in
offline images.


Researchers gathered personal information previously unknown
from a face by training an algorithm to identify Facebook profile
owners.

there may be great
potential for commercial, personal, and law
enforcement users of this emerging technology, its
development also raises numerous questions about
individual privacy”
