This document discusses Facebook's new Graph Search feature and some privacy concerns it raises. Graph Search allows users to search for connections between people, interests, locations, and other information shared on Facebook. However, the document notes that surprising amounts of personal data can now be discovered about users and their connections through Graph Search. A number of privacy issues are raised, such as whether public data should be blurred, if users know their data is public, and the potential for personal data to be linked and extrapolated in unintended ways.

2. Introducing Graph Search

3. Discovery via friends
• People who share your interests
• People who like your photographs
• People who live in Manchester and like
restaurants in Leeds
• Films that your married friends like
• Books that my relatives like
• Photographs taken in London before 2003

4. Discovery from strangers
• People who like wargaming
– and who live in Basildon
• People who like eHarmony (a dating site)
– And who are married
• Pastors who like Ann Summers (an adult
store)
• People who like Alcoholics Anonymous
– And who work for Microsoft
– Or who work for Google

5. In other words
• With Graph Search you can look up anything
that has been shared with you on Facebook
• Other people can find things you have shared
with them

6. Privacy issues
• Control who sees your Profile on the About
Tab
• Review photographs that you have shared or
been tagged in
• Review your posts with location tags in your
activity log

7. Using Graph Search

12. However...
• It’s surprising what you can actually find out...

17. But hang on!
• Only two married men out of millions of men
who are that stupid?
• How trustworthy are these results?

18. Let’s get back on track

24. Concerns
•
•
•
•
Should I worry about blurring out faces etc?
After all, it IS public data. Isn’t it?
Do these people know that it’s public?
What responsibility, if any, do I have for or
with their data?
• At what point do we need worry about linking
A + B data to get C, which may be private?

25. More concerns
• Up to what point can we extrapolate?
• Does ‘liberal minded’ in a ‘complicated
relationship’ mean something that others
might think is a bit sleazy?
• If we don’t think so, what about other people
who will?

26. Targeting selling
• Easy to find all the people who like Argos
• Then corrolate to those who also like
gardening
• Then who live in a particular area
• Promote a 20% off offer on lawnmowers!
• Is this acceptable? After all, it’s advertising
they might actually want!
