When Disclosure Is Involuntary: Empowering Users With Control To Reduce Concerns, David W. Wilson, Ryan M. Schuetzler, Bradley Dorn, Jeffrey Gainer Proudfoot

Ryan Schuetzler

Modern organizations must carefully balance the practice of gathering large amounts of valuable data from individuals with the associated ethical considerations and potential negative public image inherent in breaches of privacy. As it becomes increasingly commonplace for many types of information to be collected without individuals' knowledge or consent, managers and researchers alike can benefit from understanding how individuals react to such involuntary disclosures, and how these reactions can impact evaluations of the data-collecting organizations. This research develops and empirically tests a theoretical model that shows how empowering individuals with a sense of control over their personal information can help …

Patient Preferences For Authentication And Security: A Comparison Study Of Younger And Older Patients, Ann Fruhling, Devika Ramachandran, Tamara Bernard, Ryan Schuetzler, John R. Windle

Ryan Schuetzler

We examine authentication and security preferences of younger versus older patients in the healthcare domain. Previous research has investigated users' perception of the acceptability of various forms of authentication in nonhealthcare domains, but not patients’ preferences. First, we developed an interactive prototype to test three authentication methods: passwords, pattern, and voice. Our results indicate that younger patients prefer passwords by a significant margin. Older patients indicated more mixed preferences. In addition, we evaluated the level of security patients desired for protection of health information compared to financial information. We found no difference based on age: both groups felt financial security …

A Field Trial Of Privacy Nudges For Facebook, Yang Wang, Pedro Giovanni Leon, Alessandro Acquisti, Lorrie Faith Cranor, Alain Forget, Norman Sadeh

Lorrie F Cranor

Anecdotal evidence and scholarly research have shown that Internet users may regret some of their online disclosures. To help individuals avoid such regrets, we designed two modifications to the Facebook web interface that nudge users to consider the content and audience of their online disclosures more carefully. We implemented and evaluated these two nudges in a 6-week field trial with 28 Facebook users. We analyzed participants' interactions with the nudges, the content of their posts, and opinions collected through surveys. We found that reminders about the audience of posts can prevent unintended disclosures without major burden; however, introducing a time …

Your Location Has Been Shared 5,398 Times! A Field Study On Mobile App Privacy Nudging (Cmu-Isr-14-116), Hazim Almuhimedi, Florian Schaub, Norman Sadeh, Idris Adjerid, Alessandro Acquisti, Joshua Gluck, Lorrie Cranor, Yuvraj Agarwal

Lorrie F Cranor

Smartphone users are often unaware of the data collected by apps running on their devices. We report on a study that evaluates the benefits of giving users an app permission manager and of sending them nudges intended to raise their awareness of the data collected by their apps. Our study provides both qualitative and quantitative evidence that these approaches are complementary and can each play a significant role in empowering users to more effectively control their privacy. For instance, even after a week with access to the permission manager, participants benefited from nudges showing them how often some of their …

An Approach To Identity Management In Clouds Without Trusted Third Parties, Akram Y. Sarhan, Leszek T. Lilien

Akram YM Sarhan

The management of sensitive data, including identity management (IDM), is an important problem in cloud computing, fundamental for authentication and fine-grained service access control. Our goal is creating an efficient and robust IDM solution that addresses critical issues in cloud computing. The proposed IDM scheme does not rely on trusted third parties (TTPs) or trusted dealers. The scheme is a multiparty interactive solution that combines RSA distributed key generation and attribute-based encryption. We believe that it will be a robust IDM privacy-preserving solution in cloud computing, because it has the following features: (i) protects sensitive data on untrusted hosts using …

Measuring Privacy Disclosures In Url Query Strings, Andrew G. West, Adam J. Aviv

Andrew G. West

Publicly posted URLs may contain a wealth of information about the identities and activities of the users who share them. URLs often utilize query strings (i.e., key-value pairs appended to the URL path) as a means to pass session parameters and form data. While often benign and necessary to render the web page, query strings sometimes contain tracking mechanisms, user names, email addresses, and other information that users may not wish to publicly reveal. In isolation this is not particularly problematic, but the growth of Web 2.0 platforms such as social networks and micro-blogging means URLs (often copy-pasted from web …

Challenges For Mapreduce In Big Data, Katarina Grolinger, Michael Hayes, Wilson Higashino, Alexandra L'Heureux, David Allison, Miriam Capretz

Wilson A Higashino

In the Big Data community, MapReduce has been seen as one of the key enabling approaches for meeting continuously increasing demands on computing resources imposed by massive data sets. The reason for this is the high scalability of the MapReduce paradigm which allows for massively parallel and distributed execution over a large number of computing nodes. This paper identifies MapReduce issues and challenges in handling Big Data with the objective of providing an overview of the field, facilitating better planning and management of Big Data projects, and identifying opportunities for future research in this field. The identified challenges are grouped …

On The Privacy Concerns Of Url Query Strings, Andrew G. West, Adam J. Aviv

Andrew G. West

URLs often utilize query strings (i.e., key-value pairs appended to the URL path) as a means to pass session parameters and form data. Often times these arguments are not privacy sensitive but are necessary to render the web page. However, query strings may also contain tracking mechanisms, user names, email addresses, and other information that users may not wish to reveal. In isolation such URLs are not particularly problematic, but the growth of Web 2.0 platforms such as social networks and micro-blogging means URLs (often copy-pasted from web browsers) are increasingly being publicly broadcast.

This position paper argues that the …

Big Data: New Opportunities And New Challenges, Katina Michael, Keith Miller

Associate Professor Katina Michael

We can live with many of the uncertainties of big data for now, with the hope that its benefits will outweigh its harms, but we shouldn't blind ourselves to the possible irreversibility of changes—whether good or bad—to society.

It's no secret that both private enterprise and government seek greater insights into people's behaviors and sentiments. Organizations use various analytical techniques—from crowdsourcing to genetic algorithms to neural networks to sentiment analysis—to study both structured and unstructured forms of data that can aid product and process discovery, productivity, and policy-making. This data is collected from numerous sources including sensor networks, government data …

Balance Or Trade-Off? Online Security Technologies And Fundamental Rights, Mireille Hildebrandt

Mireille Hildebrandt

In this contribution I argue that the image of the balance is often used to defend the idea of a trade-off. To understand the drawbacks of this line of thought I will explore the relationship between online security technologies and fundamental rights, notably privacy, non-discrimination, freedom of speech and due process. After discriminating between three types of online security technologies I will trace the reconfiguration of the notion of privacy in the era of smart environments. This will lead to an inquiry into the metaphor of the scale, building on the triple test regarding the justification of the limitation of …

The Social Implications Of Covert Policing, Simon Bronitt, Clive Harfield, K. Michael

Clive Harfield

Police agencies have been accused of suffering from an acute form of technophilia. Rather than representing some dreadful disorder, this assessment reflects the strong imperative, both in police agencies and the wider community, that police must have access to the latest technologies of surveillance and crime detection.

The last decade has witnessed the proliferation of low-cost surveillance technologies, some developed specifically for law enforcement purposes. Technology once the preserve of the military or secret intelligence agencies is now within the reach of ordinary general duties police officers. The new generation of police recruits is highly adept at using new technologies. …

Introduction To The Value Of Personal Data, Mireille Hildebrandt, Kieron O'Hara, Michael Waidner

Mireille Hildebrandt

This Chapter provides an introduction to and overview of the 2013 Yearbook of the Digital Enlightenment Forum, on the subject of the value of personal data. It discusses why we should care about the current monetization of our personal data and raises the issue of whether and, if so, how user-centric personal data ecosystems help to rebalance power asymmetries between individual citizens and large Personal Data Processing Systems.

Location And Tracking Of Mobile Devices: Überveillance Stalks The Streets, Katina Michael, Roger Clarke

Professor Katina Michael

During the last decade, location-tracking and monitoring applications have proliferated, in mobile cellular and wireless data networks, and through self-reporting by applications running in smartphones that are equipped with onboard global positioning system (GPS) chipsets. It is now possible to locate a smartphone-user's location not merely to a cell, but to a small area within it. Innovators have been quick to capitalise on these location-based technologies for commercial purposes, and have gained access to a great deal of sensitive personal data in the process. In addition, law enforcement utilise these technologies, can do so inexpensively and hence can track many …

Towards A Conceptual Model Of User Acceptance Of Location-Based Emergency Services, Anas Aloudat, Katina Michael

Professor Katina Michael

This paper investigates the introduction of location-based services by government as part of an all-hazards approach to modern emergency management solutions. Its main contribution is in exploring the determinants of an individual’s acceptance or rejection of location services. The authors put forward a conceptual model to better predict why an individual would accept or reject such services, especially with respect to emergencies. While it may be posited by government agencies that individuals would unanimously wish to accept life-saving and life-sustaining location services for their well-being, this view remains untested. The theorised determinants include: visibility of the service solution, perceived service …

Privacy Issues And Solutions In Social Network Sites, Xi Chen, Katina Michael

Associate Professor Katina Michael

The boom of the internet and the explosion of new technologies have brought with them new challenges and thus new connotations of privacy. Clearly, when people deal with e-government and e-business, they do not only need the right to be let alone, but also to be let in secret. Not only do they need freedom of movement, but also to be assured of the secrecy of their information. Solove [6] has critiqued traditional definitions of privacy and argued that they do not address privacy issues created by new online technologies. Austin [7] also asserts: “[w]e do need to sharpen and …

Privacy- The Times They Are A-Changin', M.G. Michael, Katina Michael

Professor Katina Michael

This special section is dedicated to privacy in the information age. Since the rise of mobile social media in particular and the advent of cloud computing few can dispute that the times have changed. Privacy is now understood in context, and within a framework that is completely different to what it once was. The right to be let alone physically seemingly has been replaced by the right to give away as much information as you want virtually. What safeguards can be introduced into such a society? We cannot claim to wish for privacy as a right if we ourselves do …

Glogging Your Every Move, Lisa Wachsmuth, Katina Michael

Professor Katina Michael

"It is one thing to lug technologies around, another thing to wear them, and even more intrusive to bear them... But that's the direction in which we're headed."

"I think we're entering an era of person-view systems which will show things on ground level and will be increasingly relayed to others via social media.

"We've got people wearing recording devices on their fingers, in their caps or sunglasses - there are huge legal and ethical implications here."

Social Implications Of Technology: Past, Present, And Future, Karl D. Stephan, Katina Michael, M.G. Michael, Laura Jacob, Emily Anesta

Professor Katina Michael

The social implications of a wide variety of technologies are the subject matter of the IEEE Society on Social Implications of Technology (SSIT). This paper reviews the SSIT’s contributions since the Society’s founding in 1982, and surveys the outlook for certain key technologies that may have significant social impacts in the future. Military and security technologies, always of significant interest to SSIT, may become more autonomous with less human intervention, and this may have both good and bad consequences. We examine some current trends such as mobile, wearable, and pervasive computing, and find both dangers and opportunities in these trends. …

Location Privacy Under Dire Threat As Uberveillance Stalks The Streets, Katina Michael, Roger Clarke

Associate Professor Katina Michael

Location tracking and monitoring applications have proliferated with the arrival of smart phones that are equipped with onboard global positioning system (GPS) chipsets. It is now possible to locate a smart phone user down to 10 metres of accuracy on average. Innovators have been quick to capitalise on this emerging market by introducing novel pedestrian tracking technologies which can denote the geographic path of a mobile user. At the same time there is contention by law enforcement personnel over the need for a warrant process to track an individual in a public space. This paper considers the future of location …

Implementing Namebers Using Microchip Implants: The Black Box Beneath The Skin, Katina Michael, M.G. Michael

Associate Professor Katina Michael

The use of electronic-based physical access cards to secure premises such as government buildings and large corporate offices has been in operation since the inception of bar code and magnetic-stripe cards in the 1970s. Over time, for secure access control, these first generation card technologies based on optical character recognition (OCR) and magnetic ink character recognition (MICR) were replaced by more sophisticated technologies such as smart cards and biometrics, containing encrypted data and techniques which were more difficult to dupe or to replicate \cite{michael2003a}.
