Preview abstract
Online content creators---who create and share their content on platforms such as Instagram, TikTok, Twitch, and YouTube---are uniquely at-risk of increased digital-safety threats due to their public prominence, the diverse social norms of wide-ranging audiences, and their access to audience members as a valuable resource. We interviewed 23 creators to understand their digital-safety experiences. This includes the security, privacy, and abuse threats they have experienced across multiple platforms and how the threats have changed over time. We also examined the protective practices they have employed to stay safer, including tensions in how they adopt the practices. We found that creators have diverse threat models that take into consideration their emotional, physical, relational, and financial safety. Most adopted protections---including distancing from technology, moderating their communities, and seeking external or social support---only after experiencing a serious safety incident. Lessons from their experiences help us better prepare and protect creators and ensure a diversity of voices are present online.

Preview abstract
Addressing digital security and privacy issues can be particularly difficult for users who face challenging circumstances. We performed semi-structured interviews with residents and staff at 4 transitional homeless shelters in the U.S. San Francisco Bay Area (n=15 residents, 3 staff) to explore their digital security and privacy challenges. Based on these interviews, we outline four tough times themes -- challenges experienced by our financially insecure participants that impacted their digital security and privacy -- which included: (1) limited financial resources, (2) limited access to reliable devices and Internet, (3) untrusted relationships, and (4) ongoing stress. We provide examples of how each theme impacts digital security and privacy practices and needs. We then use these themes to provide a framework outlining opportunities for technology creators to better support users facing security and privacy challenges related to financial insecurity.

Preview abstract
Recognizing how intimate partner abuse’s three phases—physical control, escape from abuser, and life apart—affect survivors’ technology use can help technology creators better understand and support this population’s digital security and privacy needs.

We present a qualitative study of the digital privacy and security motivations, practices, and challenges of survivors of intimate partner abuse (IPA). This paper provides a framework for organizing survivors' technology practices and challenges into three phases: physical control, escape, and life apart. This three-phase framework combines technology practices with three phases of abuse to provide an empirically sound method for technology creators to consider how survivors of IPA can leverage new and existing technologies. Overall, our results suggest that the usability of and control over privacy and security functions should be or continue to be high priorities for technology creators seeking ways to better support survivors of IPA.

“She’ll just grab any device that’s closer”: A Study of Everyday Device & Account Sharing in Households

Proceedings of the ACM Conference on Human Factors in Computing Systems, ACM (2016) (to appear)
Preview abstract
Many technologies assume a single user will use an account or device. But account and device sharing situations (when 2+ people use a single device or account) may arise during everyday life. We present results from a multiple-methods study of device and account sharing practices among household members and their relations. Among our findings are that device and account sharing was common, and mobile phones were often shared despite being considered “personal” devices. Based on our study results, we organize sharing practices into a taxonomy of six sharing types — distinct patterns of what, why, and how people shared. We also present two themes that cut across sharing types: that (1) trust in sharees and (2) convenience highly influenced sharing practices. Based on these findings, implications for study and technology design.

Perceived Frequency of Advertising Practices

Symposium on Usable Privacy and Security (SOUPS), Privacy Personas and Segmentation Workshop, Usenix (2015)
Preview abstract
In this paper, we introduce a new construct for measuring individuals’ privacy-related beliefs and understandings, namely their perception of the frequency with which information about individuals is gathered and used by others for advertising purposes. We introduce a preliminary instrument for measuring this perception, called the Ad Practice Frequency Perception Scale. We report data from a survey using this instrument, as well as the results of an initial clustering of participants based on this data. Our results, while preliminary, suggest that this construct may have future potential to characterize and segment individuals, and is worthy of further exploration.
