What words and images
come to mind when you
think of privacy?

Privacy should not be viewed as
ALL or NOTHING
but rather along a
CONTINUUM
8
So how do we balance our desire for
privacy with the desire to share
personal information?
9
To understand privacy, context matters. 10
Privacy in context: Multiple European countries sued
Google over Street View for perceived privacy violations
11
Selective self-presentation: We highlight certain
aspects of our identities and minimize others; this
varies based on audience (see work by Erving Goffman)

To what extent can you
shape your self-
presentation in systems
categorized by flattened
networks?
To what extent have these
new social systems
reshaped our understanding
of & norms around privacy?

Audience
(Who comprises
my network?)
Disclosure
(What do I disclose &
with whom?)
Privacy
(What are my concerns
about sharing? How do I
manage my privacy?)

As networks grow
larger and more
diverse, users make
more disclosures
and those
disclosures are
characterized by
higher
intentionality.

As a user’s privacy
concerns increase,
the amount of

decrease, and the
conscious intention
increases.

Users who employed
Friend Lists to segment
their networks were
more intentional in
their posts.
Posts to Friend Lists
were more honest,
intimate, detailed, and
sincere than updates to
their whole network.

Affordances on Disclosures & Privacy Practices
User-Identified Goals
Social approval
Social Control
Intimacy
Identity Clarification
Relief of Distress
Digital Diary
User-Identified Risks
Social rejection
Hurt feelings
Reduction of integrity
Loss of control
Affordance-based risks
28
See Omarzu (2000) and Baxter and Montgomery (1996) for research on
disclosure goals and risks.

Study 2 (Vitak & Kim, 2014): Impact of
Facebook’s Affordances on Disclosure Practices
Risk Management Strategies
1. Network regulation
2. Targeted disclosures
3. Self-censorship
4. Content regulation
30
I’m communicating to people from all walks of my life, and I want to make
sure that what I’m putting out there is appropriate for everybody that’s going to see
it. And so I do have that moment of censoring everything before I put it to make
sure, ‘Oh yeah, there’s these people seeing it.’
Study 3 (Vitak et al., under review): Balancing
audience & privacy tensions on Facebook
Conceptualizing “friendship” online.
31
Facebook network
(range 82-1600)
“Actual” friends
(range 10-1000)
What is a Facebook Friend?
A known social connection.
What is an actual friend?
 Someone I’d have over to my
house for dinner.
 Communicates with more
frequently.
 Communicates with through a
variety of channels.
Study 3 (Vitak et al., under review): Balancing
audience & privacy tensions on Facebook
Relationship between audience & privacy concerns.
Two primary categories:
1. Concerns related to existing
Friends (often managed by
high self-monitoring)
2. Concerns related to audiences
outside immediate network
(e.g., potential employers)
32
“I’m very, very aware that whatever
gets out cannot be brought back. It’s
kind of a Pandora’s box. So I’m
concerned that personal information
that I would not want out in public
would somehow get released.”
Where to next?
People are wired to engage in reactive-based
strategies when it comes to managing their
privacy and self-presentation.
33
We need to reboot
users’ cognitive
processes around
privacy & disclosure.

This is already underway…
Privacy “nudges” help remind people of their
options on various sites.
34
From Facebook’s Privacy Team – See Slate article by Will Oremus
…but more needs to be done.
Our understanding of networked privacy is still limited.
35
Mental Framework for
Understanding Privacy in
Online Settings
Influenced by:
• Norms
• Age
• Other demographics
• Network composition on given site
• Privacy efficacy
• Previous privacy-related
experiences
How We Act Online
Includes:
• What we disclose
• Who we interact with
• The sites we use
• How we use those sites
• If/how we engage with sites'
privacy settings
…but more needs to be done.
Extra attention needs to be
paid to specific populations.
1. Young people (teens &
pre-teens)
2. Older adults
3. Those with low
media/computer literacy
36Flickr: jessycat_techie
…but more needs to be done.
Focus on education & behavioral change.
1. Intervention focused on increasing digital
literacy & privacy management knowledge.
2. Intervention focused on inducing behavioral
change by reducing reactive privacy
management in favor of more proactive
behaviors.
