(2016): Data Science and Designing for Privacy. In: Techné: Research in Philosophy and Technology 20 (1), S. 51-68. DOI: 10.5840/techne201632446
Abstract: Unprecedented advances in the ability to store, analyze, and retrieve data is the hallmark of the information age. Along with enhanced capability to identify meaningful patterns in large data sets, contemporary data science renders many classical models of privacy protection ineffective. Addressing these issues through privacy-sensitive design is insufficient because advanced data science is mutually exclusive with preserving privacy. The special privacy problem posed by data analysis has so far escaped even leading accounts of informational privacy. Here, I argue that accounts of privacy must include norms about information processing in addition to norms about information flow. Ultimately, users need the resources to control how and when personal information is processed and the knowledge to make information decisions about that control. While privacy is an insufficient design constraint, value-sensitive design around control and transparency can support privacy in the information age.

(2016): Information Privacy and Social Self-Authorship. In: Techné: Research in Philosophy and Technology 20 (3), S. 216-239. DOI: 10.5840/techne201671548
Abstract: The dominant approach in privacy theory defines information privacy as some form of control over personal information. In this essay, I argue that the control approach is mistaken, but for different reasons than those offered by its other critics. I claim that information privacy involves the drawing of epistemic boundaries—boundaries between what others should and shouldn’t know about us. While controlling what information others have about us is one strategy we use to draw such boundaries, it is not the only one. We conceal information about ourselves and we reveal it. And since the meaning of information is not self-evident, we also work to shape how others contextualize and interpret the information that they have about us. Information privacy is thus about more than controlling information; it involves the constant work of producing and managing public identities, what I call “social self-authorship.” In the second part of the essay, I argue that thinking about information privacy in these terms reveals threats to privacy that the control approach neglects. Namely, information technology makes social self-authorship invisible and unnecessary by making it difficult for us to know when others are forming impressions about us and by providing others with tools for making assumptions about who we are which obviate the need for our involvement in the process.

(2015): Implicit Contextual Integrity in Online Social Networks. In: Information Sciences 325, S. 48-69. DOI: 10.1016/j.ins.2015.07.013
Abstract: Many real incidents demonstrate that users of Online Social Networks need mechanisms that help them manage their interactions by increasing the awareness of the different contexts that coexist in Online Social Networks and preventing them from exchanging inappropriate information in those contexts or disseminating sensitive information from some contexts to others. Contextual integrity is a privacy theory that conceptualises the appropriateness of information sharing based on the contexts in which this information is to be shared. Computational models of Contextual Integrity assume the existence of well-defined contexts, in which individuals enact pre-defined roles and information sharing is governed by an explicit set of norms. However, contexts in Online Social Networks are known to be implicit, unknown a priori and ever changing; users relationships are constantly evolving; and the information sharing norms are implicit. This makes current Contextual Integrity models not suitable for Online Social Networks. In this paper, we propose the first computational model of Implicit Contextual Integrity, presenting an information model for Implicit Contextual Integrity as well as a so-called Information Assistant Agent that uses the information model to learn implicit contexts, relationships and the information sharing norms in order to help users avoid inappropriate information exchanges and undesired information disseminations. Through an experimental evaluation, we validate the properties of the model proposed. In particular, Information Assistant Agents are shown to: (i) infer the information sharing norms even if a small proportion of the users follow the norms and in presence of malicious users; (ii) help reduce the exchange of inappropriate information and the dissemination of sensitive information with only a partial view of the system and the information received and sent by their users; and (iii) minimise the burden to the users in terms of raising unnecessary alerts.

(2014): Medical professionalism. An experimental look at physicians’ Facebook profiles. In: Medical Education Online 19 (1). DOI: 10.3402/meo.v19.23149
DOI: https://doi.org/10.3402/meo.v19.23149 Abstract: BACKGROUND: Use of social networking services (SNS) is on the rise. While many users sign in for personal purposes, it is not uncommon for professionals to connect over SNSs with clients, students, and patients. METHODS: The present study used an experimental approach to examine how medical doctors' SNS profiles impacted potential patients' impressions of professionalism. Participants (N=250 students) were randomly assigned to view one of six Facebook profiles. Profiles were populated with 1) solely professional material, 2) personal material that was strictly healthy, or 3) personal material that included unhealthy behavior. Profiles portrayed a male or female physician resulting in a total of six experimental conditions. Medical professionalism was measured with the First Impressions of Medical Professionalism (FIMP) scale, specifically developed for this study. RESULTS: There was a large and statistically significant main effect for profile type, F(2, 250)=54.77, p<0.001, ηp(2)=0.31. Post hoc tests indicated that personal profiles that contained healthy behavior were rated as most professional followed by profiles with strictly professional content. Personal unhealthy profiles were rated as least professional. Additionally, female profiles consistently received higher professionalism ratings across all three profile types [F(1, 250)=5.04, p=0.026, ηp(2)=0.02]. CONCLUSION: Our results suggest that a physician's SNS profile affects a patient's perception of that physician's medical professionalism. A personal, healthy profile may augment a patient's perception of that physician's character virtues if the profile content upholds the decorum of the medical field.
