The popularity of online social media sites (OSM) like Facebook and
Twitter have led to a renewed discussion about user privacy concerns
today. These sites now mediate the sharing of personal information,
photos, status updates, and contacts of billions of users around the
world; some OSMs even serve as the de-facto internet portal for a
significant fraction of the world's population. However, in OSMs, users
themselves are burdened to manage the privacy for the large number of
social content they post. As a result, often, the user specified privacy
settings do not match user expectation. Consequently, in recent years
numerous news media reports as well as research studies captured users'
concern with protecting privacy of their social media content. These
reports and studies boldly underline the users' urgent need for better
privacy control mechanisms. Thus, today, the key research challenge in
this space is: How do we provide improved privacy protection to OSM
users for their social content? In this thesis, we propose approaches to
address this question.

In this talk, I will first motivate my thesis research with privacy
violation examples from real world which are not captured by access
control, the dominant privacy model today. Then I will propose exposure
control, a more inclusive privacy model to capture such violations. We
define exposure for a content as the set of people who actually view the
content. Next I will present an brief overview of our work on
understanding and controlling exposure into three different real world
scenarios -- (1) Understanding and controlling exposure using social
access control lists (SACLs) (2) Controlling exposure by limiting
large-scale social data aggregators and (3) Understanding and
controlling longitudinal exposure in OSMs. i.e., how users control
exposure of their old content. Finally I will expand upon the
understanding and controlling longitudinal exposure in OSMs and propose
our ongoing work on designing mechanisms to better control the
longitudinal exposure.
