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.

individual privacy”
