Watson, Jason, Besmer, Andrew and Lipford, Heather Richter (2012): +Your circles: sharing behavior on Google+. In: Proceedings of the 2012 Symposium on Usable Privacy and Security 2012. p. 12.

Users are sharing and consuming enormous amounts of information through online social network interaction every day. Yet, many users struggle to control what they share to their overlapping social spheres. Google+ introduces circles, a mechanism that enables users to group friends and use these groups to control their social network feeds and posts. We present the results of a qualitative interview study on the sharing perceptions and behavior of 27 Google+ users. These results indicate that many users have a clear understanding of circles, using them to target information to those most interested in it. Yet, despite these positive perceptions, there is only moderate use of circles to control information flow. We explore reasons and risks associated with these behaviors and provide insight on the impact and open questions of this privacy mechanism.

Besmer, Andrew, Watson, Jason and Lipford, Heather Richter (2010): The impact of social navigation on privacy policy configuration. In: Proceedings of the 2010 Symposium on Usable Privacy and Security 2010. p. 7.

Social navigation is a promising approach to help users make better privacy and security decisions using community knowledge and expertise. Social navigation has recently been applied to several privacy and security systems such as peer-to-peer file sharing, cookie management, and firewalls. However, little empirical evaluation of social navigation cues has been performed in security or privacy systems to understand the real impact such knowledge has on user behavior and the resulting policies. In this paper, we explore the application of social navigation to access control policy configuration using an empirical between subjects study. Our results indicate that community information does impact user behavior, but only when the visual representation of the cue is sufficiently strong.

Besmer, Andrew and Lipford, Heather Richter (2010): Moving beyond untagging: photo privacy in a tagged world. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 1563-1572.

Photo tagging is a popular feature of many social network sites that allows users to annotate uploaded images with those who are in them, explicitly linking the photo to each person's profile. In this paper, we examine privacy concerns and mechanisms surrounding these tagged images. Using a focus group, we explored the needs and concerns of users, resulting in a set of design considerations for tagged photo privacy. We then designed a privacy enhancing mechanism based on our findings, and validated it using a mixed methods approach. Our results identify the social tensions that tagging generates, and the needs of privacy tools to address the social implications of photo privacy management.

Besmer, Andrew and Lipford, Heather Richter (2010): Users' (mis)conceptions of social applications. In: Proceedings of the 2010 Conference on Graphics Interface 2010. pp. 63-70.

Many social network sites, such as Facebook and MySpace, feature social applications, applications and services written by third party developers that provide additional functionality linked to a user's profile. Current platforms allow these applications to consume much of a user's profile information, as well as the profile information of the user's friends. Researchers are proposing mechanisms to reduce the risks of this data sharing, yet these efforts need to be informed with an understanding of application use and impressions. This paper examines users' motivations, intentions, and concerns with using applications, as well as their perceptions of data sharing. Our results indicate that the social interaction driving application use is also leading to a lack of awareness of data sharing, its risks, and its implications.

Besmer, Andrew and Lipford, Heather (2009): Tagged photos: concerns, perceptions, and protections. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 4585-4590.

Photo sharing has become a popular feature of many online social networking sites. Many of the photo sharing applications on these sites, allow users to annotate photos with those who are in them. A number of researchers have examined the social uses and privacy issues of online photo sharing sites, but few have explored the privacy issues of photo sharing in social networks. In this paper, we begin by examining some of our findings from a series of focus groups on photo privacy in the social networking domain. We then devise a new mechanism to enhance photo privacy based on these findings.

Besmer, Andrew, Lipford, Heather Richter, Shehab, Mohamed and Cheek, Gorrell (2009): Social applications: exploring a more secure framework. In: Proceedings of the 2009 Symposium on Usable Privacy and Security 2009. p. 2.

Online social network sites, such as MySpace, Facebook and others have grown rapidly, with hundreds of millions of active users. A new feature on many sites is social applications -- applications and services written by third party developers that provide additional functionality linked to a user's profile. However, current application platforms put users at risk by permitting the disclosure of large amounts of personal information to these applications and their developers. This paper formally abstracts and defines the current access control model applied to these applications, and builds on it to create a more secure framework. We do so in the interest of preserving as much of the current architecture as possible, while seeking to provide a practical balance between security and privacy needs of the users, and the needs of the applications to access users' information. We present a user study of our interface design for setting a user-to-application policy. Our results indicate that the model and interface work for users who are more concerned with their privacy, but we still need to explore alternate means of creating policies for those who are less concerned.
