Optional Data Disclosure and the Online Privacy Paradox: A UK Perspective

Opinion polls suggest that the public value their privacy, with majorities calling for greater control of their data. However, individuals continue to use online services which place their personal information at risk, comprising a Privacy Paradox. Previous work has analysed this phenomenon through after-the-fact comparisons, but not studied disclosure behaviour during questioning. We physically surveyed UK cities to study how the British public regard privacy and how perceptions differ between demographic groups. Through analysis of optional data disclosure, we empirically examined whether those who claim to value their privacy act privately with their own data. We found that both opinions and self-reported actions have little effect on disclosure, with over 99 % of individuals revealing private data needlessly. We show that not only do individuals act contrary to their opinions, they disclose information needlessly even whilst describing themselves as private. We believe our findings encourage further analysis of data disclosure, as a means of studying genuine privacy behaviour.

Future scenarios and challenges for security and privacy

Over the past half-century, technology has evolved beyond our wildest dreams. However, while the benefits of technological growth are undeniable, the nascent Internet did not anticipate the online threats we routinely encounter and the harms which can result. As our world becomes increasingly connected, it is critical we consider what implications current and future technologies have for security and privacy. We approach this challenge by surveying 30 predictions across industry, academia and international organisations to extract a number of common themes. Through this, we distill 10 emerging scenarios and reflect on the impact these might have on a range of stakeholders. Considering gaps in best practice and requirements for further research, we explore how security and privacy might evolve over the next decade. We find that existing guidelines both fail to consider the relationships between stakeholders and do not address the novel risks from wearable devices and insider threats. Our approach rigorously analyses emerging scenarios and suggests future improvements, of crucial importance as we look to pre-empt new technological threats.

Interaction and Transformation on Social Media: The Case of Twitter Campaigns:

The increasing popularity of social media platforms creates new digital social networks in which individuals can interact and share information, news, and opinion. The use of these technologies appears to have the capacity to transform current social configurations and relations, not least within the public and civic spheres. Within the social sciences, much emphasis has been placed on conceptualizing social media’s role in modern society and the interrelationships between online and offline actors and events. In contrast, little attention has been paid to exploring user practices on social media and how individual posts respond to each other. To demonstrate the value of an interactional approach toward social media analysis, we performed a detailed analysis of Twitter-based online campaigns. After categorizing social media posts based on action(s), we developed a typology of user exchanges. We found these social media campaigns to be highly heterogeneous in content, with a wide range of actions performed and substantial numbers of tweets not engaged with the substance of the campaign. We argue that this interactional approach can form the basis for further work conceptualizing the broader impact of activist campaigns and the treatment of social media as “data” more generally. In this way, analytic focus on interactional practices on social media can provide empirical insight into the micro-transformational characteristics within “campaign communication.”

Privacy Salience: Taxonomies and Research Opportunities

Privacy is a well-understood concept in the physical world, with us all desiring some escape from the public gaze. However, while individuals might recognise locking doors as protecting privacy, they have difficulty practising equivalent actions online. Privacy salience considers the tangibility of this important principle; one which is often obscured in digital environments. Through extensively surveying a range of studies, we construct the first taxonomies of privacy salience. After coding articles and identifying commonalities, we categorise works by their methodologies, platforms and underlying themes. While web browsing appears to be frequently analysed, the Internet-of-Things has received little attention. Through our use of category tuples and frequency matrices, we then explore those research opportunities which might have been overlooked. These include studies of targeted advertising and its affect on salience in social networks. It is through refining our understanding of this important topic that we can better highlight the subject of privacy.
