Users share their personal devices with different entities in various circumstances. While prior research shed light on the broad reasons behind the sharing of mobile phones, there is a dearth of systematic study to understand the user's decision-making process and the underlying preferences and concerns in the context of phone sharing. To address these gaps, we designed a prototype that we leveraged to investigate the interplay between a user's relationship with sharees, preferences of sharing a subset of apps with a certain entity, perceived sensitivity of the apps being shared, and how these factors relate to their authentication behavior. We conducted a multi-session study with 50 participants from three countries (USA, Turkey, and Nepal), where the participants interacted with our prototype and took part in semi-structured interviews. The findings from our study revealed the need for phone sharing at a granular level, where we identified the factors that could influence a user's decision-making process in sharing. Our analysis unpacked the relation between a user's perceived sensitivity of apps being shared, and authentication behavior to protect information from unauthorized access. Overall, our findings advance the CSCW community's understanding of how the user attains a balance between privacy protection and the need for phone sharing.
With the growing adoption of digital technology in healthcare organizations, it is important to understand nursing professionals' behavior and challenges, and the corresponding privacy implications around digital technology use. To this end, we conducted semi-structured interviews with 21 participants (16 nursing professionals, and five nursing faculties) in the USA. In our study with nursing professionals, we explored how they used digital technology and protected sensitive health data at their workplace. We investigated their understanding of privacy breaches and possible consequences, the challenges they encountered to maintaining privacy, and their workarounds to deal with such issues. We looked into the support that professional nurses receive in the form of organizational training, and how they collaborate with the IT department at their institution to address technical issues. In addition, we shed light on the gap between their academic preparation and professional needs in the context of digital technology use and privacy protection, where we also interviewed five nursing faculties to get more in-depth understanding of this issue from the point of view of academia. Overall, our findings provide valuable insights for the CSCW community to better understand the challenges and privacy risks in digital technology use by nursing professionals, and lead to our recommendations to address these issues.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
