  • Context paper
  • Korte introductie over Cupid
    nav cupid ook korte introductie van jou en mezelf en onze onderzoeksgroepen -> mss nog logo’s toevoegen?
  • I would like to shortly mention that “privacy” is a place, time and context dependant concept, ending by saying that privacy is not so much a right, but a freedom
  • Ik dacht dit te gebruiken als overgang naar de evolutie in facebook (punt 4 en eerste deel punt 5 van onze paper) en het legale nog even achterwege te laten, maar het kan natuurlijk ook altijd anders…
  • stukjes uit onze “discussion” en uit de bespreking van open ID in kunnen opnemen. OpenID zou ik dan nemen als een voorbeeld bij de bespreking van het transparantie beginsel. De link die ik dan zou maken is dat de meest gekende OpenID providers helaas ook diegene met de minste beveiliging zijn. Ik zou mijn stukje dan eindigen met wat we zeggen in paragrafen 5 en 6 van onze discussie.

    11. 11. 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

    16. 16. 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” Vivianne Reding “It is unacceptable that the company [facebook nvdr.] fundamentally changed the default settings to the detriment of the user” Article 29 Working Party
    17. 17. Alive or not, but still protected Europe guarantees protection of personal data through the Data Protection Directive (46/95 EC) Social Network Sites do process personal data • Personal = relating to identified or identifiable natural persons • Processing = any operation or set of operations performed upon personal data The Data Protection Directive is based on 4 principles: • Proportionality • Finality • Transparancy • Legitimacy
    18. 18. Data Protection Principles Proportionality and Finality: need to know NOT nice to know ✗ No one can collect data for the purpose of collecting
    19. 19. Data Protection Principles Transparancy: Fair processing THROUGH a guaranteed minimum level of information ✗ Unaware users are vulnerable users
    20. 20. Data Protection Principles Legality: processing after NOT before user consent ✗Consent = opt-in ≠ opt-out
    21. 21. Moving from opt-out to 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
    22. 22. 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!
