  • 1. Rheinische Fachhochschule Köln – University of Applied Science / University of Cologne Christian Bosau Privacy protection as a matter of trust: How trust in Facebook and trust in friends lead to different behaviour in social networks
  • 2. Bosau – Privacy protection as a matter of trust 8th Conference of the Media Psychology Division - 2013 Seite 2 Privacy and Facebook
  • 3. Bosau – Privacy protection as a matter of trust 8th Conference of the Media Psychology Division - 2013 Seite 3 Privacy and Facebook source: „Die Zeit“, No. 34, 14.08.2013 29 people in a small office in small Portarlington in the middle of nowhere in Irland à control whether Facebook follows the lax irish data privacy laws
  • 4. Bosau – Privacy protection as a matter of trust 8th Conference of the Media Psychology Division - 2013 Seite 4 Purpose of the study Main purpose: Looking into trust and the members‘ reaction in social networks a bit deeper Aspects about Facebook: •  members are aware of privacy risks (Bosau, Becks & Aelker, 2009; Bosau, Fischer & Koll, 2008) •  still à huge amount of usage •  members try out different protection strategies to lower privacy risks (Young & Quan- Haase, 2009) •  members restrict their profile (Utz & Krämer, 2009), however mostly to their “friends”-list •  but what about information management? The importance of privacy concerns & trust: •  how people generally think about privacy and whether they trust the requestor influences how much information they give online (Joinson, Reips, Buchanan & Paine-Schofield, 2010)
  • 5. Bosau – Privacy protection as a matter of trust 8th Conference of the Media Psychology Division - 2013 Seite 5 Two agents to be trusted The platform provider (e.g. Facebook): •  many reports discuss the misbehaviour of Facebook regarding privacy issues •  people know the risk, but don’t care? The “friends”: •  users add numerous people to their friends-list, even people, that are not close friends •  managing the increasing number of different kinds of “friends” becomes an issue Main question: Who is the requestor, i.e. the communication partner in a social network?
  • 6. Bosau – Privacy protection as a matter of trust 8th Conference of the Media Psychology Division - 2013 Seite 6 The study Method: •  online questionnaire (posted via mailing-lists and personal emails, snowball sampling) in February/March 2012 •  270 participants •  age: mean=24,8 SD=5,4 male=24%, female=76% Former studies: § measurement of privacy concerns, privacy protection behaviour & information dissemination separately This study: § combining the different aspects in one single study § differentiation between two trust agents Research question / hypotheses: •  Trust in Facebook and trust in “friends” are two separate factors. •  How do the different kinds of trust (in “friends” & in Facebook) matter, when it comes to protecting the privacy in a social network? à dependent variable: privacy protection behaviour in Facebook
  • 7. Bosau – Privacy protection as a matter of trust 8th Conference of the Media Psychology Division - 2013 Seite 7 The dependent variables Information input •  Question: “Which of the following informational aspects have you put into your profile?” •  Scale: 0 = no vs. 1 = yes •  11 items, summed up to a single indicator à amount of information •  e.g. “birthday” “address & home town” “name” “relationship status” “gender” “favourite music/hobbies/interests” “profile picture” Information deletion •  based on Young & Quan-Haase (2009), additional up-to-date aspects were added •  Scale: 1 = never vs. 5 = very often •  Cronbach’s α = .86 •  9 items •  e.g. “I have deleted unpleasant pictures from my profile.” “I have deleted unpleasant comments of myself.” “I have deleted other’s comments on my profile.” “I have told others to delete pictures that I found unpleasant.”
  • 8. Bosau – Privacy protection as a matter of trust 8th Conference of the Media Psychology Division - 2013 Seite 8 The predictors Sociodemographic control factors: Age General privacy concern & behaviour (Reips, U.-D., Buchanan, T., & Oostlander, J. ,2008, 2010): Gender Attitude Behaviour Technical Protection Behaviour General Caution Additional predictors: privacy concerns in FB (e.g. boyd & Ellison, 2008) No. of “friends” Trust (based on Joinson, Reips, Buchanan & Paine-Schofield, 2010): in “friends” in Facebook
  • 9. Bosau – Privacy protection as a matter of trust 8th Conference of the Media Psychology Division - 2013 Seite 9 General privacy concern: •  Scale by Reips, U.-D., Buchanan, T., & Oostlander, J. ,2008, 2010) •  Attitude: 16 Items (Cronbach’s α = .88): •  e.g. “Are your afraid of online identity theft”, “Are you afraid that someone could steal your credit card number online” •  Behaviour – General Concern: 6 Items (Cronbach’s α = .70): •  e.g. “Do you hide your PIN-code at an ATM”, “Do you read the data security terms and conditions before you register” •  Behaviour – Technical Protection: 6 Items (Cronbach’s α = .74): •  e.g. “Do you delete cookies”, “Do you use a pop-up-blocker” The additional predictors Specific privacy concerns in Facebook: •  Scale developed based on boyd & Ellison (2008) and Debatin, Lovejoy, Horn & Hughes (2009) •  Question “Which problems or threats do you see when using Facebook?” •  Scale: 1 = can happen hardly vs. 5 = can happen very easily •  14 Items (Cronbach’s α = .85): •  Focusing on the major concerns or threats named in the literature: •  e.g. “damaged reputation due to rumors and gossip“; “hacking or identity theft“; “phishing“; “surveillance-like structures due to backtracking“ “consumer-profiling”

  • 13. Bosau – Privacy protection as a matter of trust 8th Conference of the Media Psychology Division - 2013 Seite 13 Conclusion The “friends” in Facebook are a new important issues •  trust in “friends” and trust in Facebook are two independent factors •  trust in “friends” is quite high, while trust in Facebook is very low •  the huge number of “friends” comprises the risk of not being able to predict the behaviour of all “friends” Different kinds of trust lead to different kind of privacy protection behaviour •  low trust in “friends” leads to more protection behaviour in terms of deleting information regarding likes, comments & pictures •  low trust in Facebook leads to higher withholding of profile information, but has no influence if the information is already in Facebook Other results: •  general attitudes about privacy are to abstract and broad to be able to predict specific behaviour; though, specific Facebook concerns to not lead to protection either
