1. "It's our mutual responsibility to share": The Evolution of Account Sharing in Romantic Couples

   https://doi.org/10.1145/3449234

   While most online accounts are designed assuming a single user, past work has found that romantic couples often share many accounts. Our study examines couples' account sharing behaviors as their relationships develop. We conducted 19 semi-structured interviews with people who are currently in romantic relationships to understand couples' account sharing behaviors over the lifecycle of their relationship. We find that account sharing behaviors progress through a relationship where major changes happen at the start of cohabitation, marriage, and occasional breakup. We also find that sharing behaviors and motivations are influenced by couples' relationship ecology, which consists of the dynamics between the couples and the social environment they live in. Based on these findings, we discuss implications for further study to support couples' sharing needs at different relationship stages and identify design opportunities for technology solutions to facilitate couples' sharing.

2. MyTimeUse: An Online Implementation of the Day-Reconstruction Method

   https://doi.org/10.32797/jtur-2022-3  

   Rinderknecht, R. Gordon; Doan, Long; Sayer, Liana C. (July 2022, Journal of Time Use Research)

   Time diaries can record precise measures of daily activities but few such diaries have been developed for use via the internet, which limits our knowledge of how social, economic, and demographic factors affect daily life and our ability to investigate trends over time. We have developed, refined, and deployed an original online time diary, mytimeuse.com, to study daily life in a longitudinal sample of graduate students and a longitudinal sample of U.S. residents recruited online. This article overviews the features we implemented to increase data quality and response rates. The diary is based on the day-reconstruction method, which has participants report on each primary activity in a selected day, then records further contextual information about the activity, such as social engagement, multitasking, and emotions. We recruited online participants to complete three time diaries and report their evaluations of our platform. Feedback indicates most participants found the diary to be intuitive and easy to use, and most who made an account with the diary platform fully participated in our study.

3. "We Hold Each Other Accountable": Unpacking How Social Groups Approach Cybersecurity and Privacy Together

   https://doi.org/10.1145/3313831.3376605  

   Watson, Hue; Moju-Igbene, Eyitemi; Kumari, Akanksha; Das, Sauvik (April 2020, Proceedings of the 2020 CHI Conference on Human Factors in Computing Systems)

   Digital resources are often collectively owned and shared by small social groups (e.g., friends sharing Netflix accounts, roommates sharing game consoles, families sharing WhatsApp groups). Yet, little is known about (i) how these groups jointly navigate cybersecurity and privacy (S&P) decisions for shared resources, (ii) how shared experiences influence individual S&P attitudes and behaviors, and (iii) how well existing S&P controls map onto group needs. We conducted group interviews and a supplemental diary study with nine social groups (n=34) of varying relationship types. We identified why, how and what resources groups shared, their jointly construed threat models, and how these factors influenced group strategies for securing shared resources. We also identified missed opportunities for cooperation and stewardship among group members that could have led to improved S&P behaviors, and found that existing S&P controls often fail to meet the needs of these small social groups.

4. Share and Share Alike? An Exploration of Secure Behaviors in Romantic Relationships

   Park, Cheul Young; Faklaris, Cori; Zhao, Siyan; Sciuto, Alex; Dabbish, Laura; Hong, Jason (August 2018, Fourteenth Symposium on Usable Privacy and Security ({SOUPS} 2018))

   Security design choices often fail to take into account users' social context. Our work is among the first to examine security behavior in romantic relationships. We surveyed 195 people on Amazon Mechanical Turk about their relationship status and account sharing behavior for a cross-section of popular websites and apps (e.g., Netflix, Amazon Prime). We examine differences in account sharing behavior at different stages in a relationship and for people in different age groups and income levels. We also present a taxonomy of sharing motivations and behaviors based on the iterative coding of open-ended responses. Based on this taxonomy, we present design recommendations to support end users in three relationship stages: when they start sharing access with romantic partners; when they are maintaining that sharing; and when they decide to stop. Our findings contribute to the field of usable privacy and security by enhancing our understanding of security and privacy behaviors and needs in intimate social relationships.

5. “Citizens Too”: Safety Setting Collaboration Among Older Adults with Memory Concerns

   https://doi.org/10.1145/3465217

   Designing technologies that support the cybersecurity of older adults with memory concerns involves wrestling with an uncomfortable paradox between surveillance and independence and the close collaboration of couples. This research captures the interactions between older adult couples where one or both have memory concerns—a primary feature of cognitive decline—as they make decisions on how to safeguard their online activities using a Safety Setting probe we designed, and over the course of several informal interviews and a diary study. Throughout, couples demonstrated a collaborative mentality to which we apply a frame of citizenship in opensource collaboration, specifically (a) histories of participation , (b) lower barriers to participation, and (c) maintaining ongoing contribution. In this metaphor of collaborative enterprise, one partner (or member of the couple) may be the service provider and the other may be the participant, but at varying moments, they may switch roles while still maintaining a collaborative focus on preserving shared assets and freedom on the internet. We conclude with a discussion of what this service provider-contributor mentality means for empowerment through citizenship, and implications for vulnerable populations’ cybersecurity.
