Access Logs – Underestimated Privacy Risks

Access logs may offer service providers a lot of information about specific users. Depending on the type of the service offers, the operator is capable of obtaining the user’s IP, location, communication habits, device information and so on. In this paper, we analyze a sample instant messenger service that is operating for a certain period of time. In our sandbox, we gathered enough data to correlate user communication habits with their localization, and even contacts. We show how seriously metadata may impact the user’s privacy and make some recommendations about mitigating the quantity of data collected in connection with this type of services

Connecting Couples in Long-Distance Relationships : Towards Unconventional Computer-Mediated Emotional Communication Systems

The number of couples who find themselves in a long-distance relationship (LDR) is increasing for a wide range of reasons, such as overseas employment, academic pursuits, military duty, and similar circumstances. With the myriad of communication channels enabled by the low cost and ubiquity of computer-mediated communication technologies, couples in LDRs are able to stay in touch with each other around the globe. However, recent studies have revealed that the mainstream communication tools are inadequate to support the full spectrum of communication needed in intimate relationships. Emotional communication is one of the fundamental needs in close relationships, as it forms an important part of intimacy. This dissertation argues that there is a gap between what is known about LDR couples’ needs in research and what has been implemented for them in practice. The aim of this work is to bridge this gap by mediating emotional communication through unconventional user interfaces that use interaction solutions outside of the scope of their conventional use, with a particular focus on couples who sustain a committed LDR. Here, taking research through design as a core approach, a variety of qualitative methods were employed to seek answers to the research questions. This dissertation includes eight case studies, each of which is dedicated to answering its corresponding research question(s). Study I presents a systematic literature review which explored the current state of the art and identified the design opportunities. Study II introduces a series of co-design activities with five couples in LDRs to reveal the needs and challenges of users in an LDR. Studies III and IV propose two functional prototypes for unconventional communication systems to connect couples in LDRs. Study V showcases 12 design concepts of wearables created by the participants to support their own LDR. Study VI describes how four low-resolution prototypes created for mediating LDRs by the participants in the workshop would be used in real-world contexts. Studies VII and VIII each present a novel design tool to be used as a scaffold when designing communication systems for supporting LDRs: specifically, a conceptual design framework and a card-based design toolkit. This dissertation contributes new knowledge to the field of human-computer interaction through design interventions. It showcases a spectrum of practices which can be seen as a first step towards mediating emotional communication for couples in LDRs using unconventional communication systems. The findings comprise theoretical and empirical insights—derived from the eight case studies in which the author identified design opportunities and design considerations—relating to how couples in LDRs can be better supported by unconventional computer-mediated emotional communication systems

Seeing the Invisible: Understanding the Implications of Social Media Invisible Responses for Well-Being and Relational Development

Large swathes of current social media scholarship monolithically treats browsing behaviors as passive behaviors, per the passive versus active behaviors approach to social media activities. Such labeling fails to capture the numerous ways that people respond to social media sharing beyond visible clicks on the platform, such as relational distancing or switching channels to respond. Moreover, understanding what people do with information seen on social media platforms and how they respond to such information is integral to theorizing the implications of using these platforms. My dissertation tackles these challenges by first proposing the concept of invisible responses to unify the diverse approaches of responding possible to social media. Specifically, I define invisible responses as reactions to social media sharing by viewers that are invisible along any of the following dimensions: (1) to the original platform, (2) to the sharer, and (3) to the viewer’s imagined audience of third parties. The dissertation presents three empirical studies to investigate the different dimensions of invisible responses. Study 1 examines viewing time and visible clicks while browsing Facebook feeds. While viewing time—a proxy for visual attention—is largely invisible, public feedback of clicks are visible to everyone. Study 1 reveals that the combination of these two types of responses, along with the amount of social content in feeds, can predict important well-being outcome, namely self-esteem. Study 2 explores how people practice self-presentation and relational maintenance in an environment where responses are invisible to third parties. These findings suggest that, given responses that are invisible to third parties, sharers feel lower self-presentational pressure. However, what remains unchanged compared to public feedback is the emphasis on the amount of attention and effort as signaling investment in a relationship. Finally, Study 3 investigates when and why people would make their reception of a social media post invisible or not to the original sharer of the post. Once again, the findings underscore that sending signals of attention and effort is meaningful for relational maintenance. Together, the studies in this dissertation illustrate the importance of invisible responses in understanding well-being and relational outcomes of social media use, as well as opening up future avenues for research. Specifically, responding to the research agenda outlined by the communication visibility theory (Treem, Leonardi, & van den Hooff, 2020), I highlight questions around the management of visibility on social media.PHDInformationUniversity of Michigan, Horace H.

The Queer Allure of Digital Sociality

This dissertation explores the resonance between queer sociality and emergent forms of digital communication. Drawing from queer theory and LGBTQ social histories, this dissertation charts the convergence of digital social modulation with the polyvalence, promiscuity, and mutability of queer sociality. A close analysis of the infrastructure and design of Facebook, Snapchat, Grindr, and other queered social media platforms demonstrates how digital capitalism’s desire for lifelong compulsive engagement is in part facilitated by an appropriation of the ongoingness of queer sexuality and relationality. In highlighting the key role of temporality, aesthetic, and affect in regulating the creation and circulation of digital media, this dissertation frames a socio-political landscape that has moved away from the rational human subject. To engage with this developing landscape, a genealogy of queer computation and an analysis of corporeal and ecological data systems are presented to suggest a generative, digital, queer method
