  • 12. Facebook’s evolving privacy policy
    Main idea: connecting people
    With friends
    With interests
    Promise privacy of the user at the center
    Default setting: strictly limited to approved friends
    However throughout the years
    FB Beacon, FB Connect, Transition tool, Open Graph
    => Forcing users to accept opt-out services
  • 13. Facebook’s evolving default privacy settings
  • 14. Reactions on Facebook
  • 15. Reactions on Facebook

  • 17. Alive or not, but still protected
    “I am surprised by this sudden change of policy. I can’t understand that, because it is in the interest of social network sites to give users control of their privacy” VivianneReding
    “It is unacceptable that the company [facebooknvdr.] fundamentally changed the default settings to the detriment of the user” Article 29 Working Party
  • 18. Alive or not, but still protected
    Europeguaranteesprotection of personal data through the Data ProtectionDirective(46/95 EC)
    SocialNetwork Sites do processpersonal data
    Personal = relating to identifiedoridentifiablenaturalpersons
    Processing = anyoperationor set of operationsperformeduponpersonal data
    The Data ProtectionDirective is basedon4 principles:
  • 19. Data ProtectionPrinciples
    Proportionality andFinality:
    need to know NOT nice to know
    ✗ No one can collect data for the purpose of collecting
  • 20. Data ProtectionPrinciples
    Fair processing THROUGH a guaranteed minimum level of information
    ✗Unaware users are vulnerable users
  • 21. Data ProtectionPrinciples
    processing after NOT before user consent
    ✗Consent = opt-in ≠ opt-out
  • 22. Moving from opt-outto opt-in
    A user-centered privacy approach
    In control & ability to tweak
    Transparent recommendation engine
    Gives a justification of the recommendations and profile use and creates greater commitment
    Leads to knowledge, trust and involvement with complex data flows
    CUPID’s cultural profile as a personal tool to structure an experienced abundance of event information
  • 23. To conclude: Trading of privacy for personalisation?
    Facebook’s opt-out model guarantees the largest possible database… as it is a profit-organisation
    CUPID shows that privacy-friendly personalization services and social networks compliant with European Data Protection principles are possible and may be appreciated
    In a user-driven and participatory media environment consumer awareness, media literacy and self-protection are important in order to exercise power
    Opt-in can further enhance users’ power
    Allow changes to settings after consenting!
