“…In general, these privacy settings enable the users to create multiple social roles for different audiences (such as family, friends, and professional life), to keep their roles separated and consistent, and thus to protect their privacy. However, in a study we were able to show that this idealized conception of managing information flows on SNSs is far from reality [14]. Access control models and privacy settings are difficult to understand and to use, especially for less technically-savvy users.…”

Abstract. The significant change in our social lives and communication habits caused by the rise of Social Network Sites (SNSs) has not only brought along benefits but is also accompanied by privacy threats. In this paper we present our research efforts on SNS privacy and social identity management. First, we outline the results of an empirical study showing significant discrepancies between Facebook users' actual privacy settings and their perception as well as their preferences. Based on this evident need for improving privacy, we present a novel conceptualization of privacy that serves as the basis for tackling the challenges. Finally, the paper provides an overview of solutions we developed as part of our research efforts on privacy in SNSs.Keywords: Social network sites · Privacy · Social identity management MotivationSince their emergence more than a decade ago, Social Network Sites (SNSs) are increasingly changing our social lives and communication habits. While social networks have always been an important part of human life, the advent of easyto-use services and their ability to bridge boundaries -regarding both space and time -increasingly shifts social life to the online world. These networks enable communication with people from different social spheres (e.g. family, close friends, colleagues), ease interaction, and allow their users to stay in touch with existing contacts as well as to create new relationships.However, the rise of SNSs also threatens the privacy of their users. On the one hand, people on SNSs inconsiderately share many personal items (e.g. status updates, location updates, photos) while they are not fully aware of their audience. There are numerous examples of SNS users posting inappropriate pictures and status updates and consequently offending people that have access to these items (such as one's boss or parents). On the other hand, few SNS providers exist that have collected a large amount of personal data in their databases raising surveillance and data protection concerns.

“…They also show that for 24.6 % of the 8,505 binary visibility perceptions analyzed, there is a mismatch between the preferred and the actual visibility settings. Moreover, 64 % of the 68 participants want more restrictive visibility settings for at least one item [14].…”

“…Publications focus on aspects such as quantifying incorrect privacy settings (Liu et al, 2011;Netter et al, 2013;Madejski et al, Mar. 2012), examining to which extent users understand privacy settings and their impact (Strater and Lipford, 2008), assessing usage strategies of privacy settings (Kelley et al, 2011;Watson et al, 2012), and predicting user attitudes from privacy settings (Lewis et al, 2008).…”

“…We expect this to lead to a more accurate assessment of an attribute value's criticality than querying only the user's stance on an attribute but not its actual value. An interactive study on privacy expectations in SNS (Netter et al, 2013) has shown that an interactive questionaire incorporating the user's SNS account data is a feasible way to query the user about particular profile items.…”

Abstract-The growing relevance and usage intensity of Online Social Networks (OSNs) along with the accumulation of a large amount of user data has led to privacy concerns among researchers and end users. Despite a large body of research addressing OSN privacy issues, little differentiation of data types on social network sites is made and a generally accepted classification and terminology for such data is missing, hence leading to confusion in related discussions. This paper proposes a taxonomy for data types on OSNs based on a thorough literature analysis and a conceptualization of typical OSN user activities. It aims at clarifying discussions among researchers, benefiting comparisons of data types within and across OSNs and at educating the end user about characteristics and implications of OSN data types. The taxonomy is evaluated by applying it to four major OSNs.
