  • Managing your identity, tutorial 2: Protecting your Privacy- Internet Society, January 2013 - Before reading this tutorial you should think what are the important issues in online privacy from your point of view. Are they addressed by the tutorial?
  • Freedom and the Social Contract, Vinton G. Cerf, september 2013 Communications of the ACM 56(9) - a short reflection on the debate over preserving privacy and national security
  • A Primer on Metadata: Separating Fact from Fiction - Ann Cavoukian, Information and Privacy Commissioner Ontario, Canada July 2013 - "A Primer on Metadata: Separating Fact from Fiction, explains that metadata can actually be more revealing than accessing the content of our communications. The paper aims to provide a clear understanding of metadata and disputes popular claims that the information being captured is neither sensitive, nor privacy-invasive, since it does not access any content. Given the implications for privacy and freedom, it is critical that we all question the dated, but ever-so prevalent either/or, zero-sum mindset to privacy vs. security. Instead, what is needed are proactive measures designed to provide for both security and privacy, in an accountable and transparent manner."
  • Surveillance, Then and Now: Securing Privacy in Public Spaces - Ann Cavoukian, Information and Privacy Commissioner Ontario, Canada June 2013 - "Surveillance is growing, as are the technologies that extend its reach. But surveillance that facilitates the sustained monitoring of people engaged in everyday activities in public is, in Justice Gerard La Forest’s unforgettable words, “an unthinkable prospect in a free and open society such as ours.” The purpose of this paper is to assist law enforcement, lawmakers, and the broader public in understanding and protecting our fundamental right to privacy with respect to surveillance by the state of our activities in public spaces through the use of ever-growing new technologies. A proactive Privacy by Design approach is central to designing and implementing the regulatory framework needed to properly supervise state surveillance. It is our experience that, where the use of a particular surveillance technology is justified, proportionate, and effective at delivering public safety, a proactive positive-sum approach is available that will ensure that privacy, accountability, and transparency are embedded into the legal and technical design specifications of any proposed surveillance system. Whatever the future holds, we know that, in addition to privacy and freedom, people will require safety and security. We believe that now, and for the foreseeable future, it is essential that we strive to have both, in tandem. Freedom must be preserved from both terrorism and tyranny. While eternal vigilance will be required to secure our fundamental rights, including our right to privacy, we remain confident that we can have both public safety and personal privacy in public spaces. There is neither reason, nor need, to settle for anything less."
  • Two tales of privacy in online social networks. Seda Gürses and Claudia Diaz. In IEEE Security & Privacy Magazine Vol. 11(3):29-37, Special Issue on Social Networks, May/June 2013. "Privacy is one of the friction points that emerges when communications get mediated in Online Social Networks (OSNs). Different communities of computer science researchers have framed the ‘OSN privacy problem’ as one of surveillance, institutional or social privacy. In tackling these problems they have also treated them as if they were independent.We argue that the different privacy problems are entangled and that research on privacy in OSNs would benefit from a more holistic approach. In this article, we first provide an introduction to the surveillance and social privacy perspectives emphasizing the narratives that inform them, as well as their assumptions, goals and methods. We then juxtapose the differences between these two approaches in order to understand their complementarity, and to identify potential integration challenges as well as research questions that so far have been left unanswered."
  • Hero or Villain: The Data Controller in Privacy Law and Technologies. Claudia Diaz, Omer Tene, and Seda Gürses. To appear at the Ohio State Law Journal 74(6), 78 pages, 2013. "This Article demonstrates that an analysis of the assumptions and principles underlining privacy enhancing technologies (PETs) highlights the gap between the constitutional and information privacy frameworks. It argues that by embracing PETs, information privacy law can recalibrate to better protect individuals from surveillance and unwanted intrusions into their private lives."
  • Understanding the landscape of privacy technologies. Claudia Diaz and Seda Gürses. Extended abstract of invited talk in proceedings of the Information Security Summit, pp. 58-63, 2012 "In the last decades, much effort has been devoted to research on privacy across different subfields in computer science (e.g., security engineering, data mining, HCI), resulting in a broad range of solutions for addressing the “privacy problem”. Privacy is a multifaceted and complex concept that can be tackled from very different perspectives. Existing solutions rely on different definitions of privacy as well as on a variety of (often implicit) social and technical assumptions. As a result, it is hard for non-experts to understand the privacy research landscape and to put available technologies into context. In this paper we provide an overview of the landscape of privacy technologies following the classification in three privacy research paradigms proposed by Gürses [11,14]. For each of these paradigms we describe their conception of privacy and the types of privacy threats that the technologies are meant to address, present representative examples of technologies that have been proposed to address these threats, and discuss their distinguishing characteristics."
  • The Electronic Frontier Foundation’s Who has your back? Third Annual Report on Online Service Providers’ Privacy and Transparency Practices Regarding Government Access to User Data- April 30, 2013 UPDATE: May 13, 2013 - "When you use the Internet, you entrust your conversations, thoughts, experiences, locations, photos, and more to companies like Google, AT&T and Facebook. But what do these companies do when the government demands your private information? Do they stand with you? Do they let you know what’s going on? In this annual report, the Electronic Frontier Foundation examined the policies of major Internet companies — including ISPs, email providers, cloud storage providers, location based services, blogging platforms, and social networking sites — to assess whether they publicly commit to standing with users when the government seeks access to user data. The purpose of this report is to incentivize companies to be transparent about how data flows to the government and encourage them to take a stand for user privacy whenever it is possible to do so."

  • Why Privacy Matters Even if You Have 'Nothing to Hide' - The article is an excerpt from Daniel J. Solove's book, Nothing to Hide: The False Tradeoff Between Privacy and Security, Yale University Press 2011"Legal and policy solutions focus too much on the problems under the Orwellian metaphor—those of surveillance—and aren't adequately addressing the Kafkaesque problems—those of information processing. [...] Commentators often attempt to refute the nothing-to-hide argument by pointing to things people want to hide. [...] Surveillance, for example, can inhibit such lawful activities as free speech, free association, and other First Amendment rights essential for democracy. The deeper problem with the nothing-to-hide argument is that it myopically views privacy as a form of secrecy. In contrast, understanding privacy as a plurality of related issues demonstrates that the disclosure of bad things is just one among many difficulties caused by government security measures. [...] One such harm, for example, which I call aggregation, emerges from the fusion of small bits of seemingly innocuous data. [...] Another potential problem with the government's harvest of personal data is one I call exclusion. Exclusion occurs when people are prevented from having knowledge about how information about them is being used, and when they are barred from accessing and correcting errors in that data. [...] a kind of due-process problem[...]. A related problem involves secondary use. Secondary use is the exploitation of data obtained for one purpose for an unrelated purpose without the subject's consent. How long will personal data be stored? How will the information be used? What could it be used for in the future? The potential uses of any piece of personal information are vast. [...] Yet another problem with government gathering and use of personal data is distortion. [...] Privacy is often threatened not by a single egregious act but by the slow accretion of a series of relatively minor acts. In this respect, privacy problems resemble certain environmental harms, which occur over time through a series of small acts by different actors. Although society is more likely to respond to a major oil spill, gradual pollution by a multitude of actors often creates worse problems.

Procedia - Social and Behavioral Sciences, Volume 48, 2012, Pages 941-950 Scott Cruickshanks, Ben Waterson "[...] This paper examines the methodology and results of a mail survey conducted in the UK. This survey seeks to ascertain whether in the eyes of the public the potential benefits of future transport systems will outweigh the loss of personal information. The results of the survey support the fears that the advent of some future ITS applications will cause some people to travel with less freedom. It also highlights several key groups that are the most likely to reject future ITS, with contributing factors being elderly, poorly educated, female, from an ethnic minority group and/or having little experience of using the latest transport technologies"

    • Challenges in Retaining Privacy in Smart Spaces - Procedia Computer Science, Volume 19, 2013, Pages 556-564 Jimmy C. Chau, Thomas D.C. Little "[...] occupants. The privacy of the information manipulated by smart spaces quickly becomes a key barrier in realizing the full value of ambient systems and is the focus of this paper. We approach this challenge first by surveying current privacy definitions and mechanisms (access control, k-anonymity, and differential privacy) under the assumption of ambient sensors and networking found in smart spaces. We then identify how existing approaches are not suitable for smart spaces under major smart space privacy scenarios and propose adaptations with strong potential for addressing these scenarios."

  • The TOR project - TOR offers protection at the TCP/IP (transport) level and offers protection against traffic analysis which can be used either to obtain identification information or for profiling or for information extraction."Instead of taking a direct route from source to destination, data packets on the Tor network take a random pathway through several relays that cover your tracks so no observer at any single point can tell where the data came from or where it's going. ". TOR is complex to use so end-user normally use it with an user interface called Vidalia. To ensure privacy at higher levels that transport (HTTP) on should use the TOR browser bundle.

  • The makers of the social media privacy management app Mypermissions has used their attempted "standardization" approach to develop a certification for other apps and developers. This is an example of an attempt to standardize privacy policies and act as a mediator between companies and users to the management of the complexities of privacy policies. Though this approach is moving in the right direction there are many questions about how how reliable this company is to be an authority on the subject as well as factors that may be influencing their decision making. For instance, they offer a free version, but also a paid version in which they offer a/b testing and "trend alerts."
  • AppPrivacy free privacy policy generator
  • Sleights of privacy: framing, disclosures, and the limits of transparency Idris Adjerid Alessandro Acquisti Laura Brandimarte George Loewenstein (2013) - In an effort to address persistent consumer privacy concerns, policy makers and the data industry seem to have found common grounds in proposals that aim at making online privacy more "transparent." Such self-regulatory approaches rely on, among other things, providing more and better information to users of Internet services about how their data is used. However, we illustrate in a series of experiments that even simple privacy notices do not consistently impact disclosure behavior, and may in fact be used to nudge individuals to disclose variable amounts of personal information. In a first experiment, we demonstrate that the impact of privacy notices on disclosure is sensitive to relative judgments, even when the objective risks of disclosure actually stay constant. In a second experiment, we show that the impact of privacy notices on disclosure can be muted by introducing simple misdirections that do not alter the objective risk of disclosure. These findings cast doubts on the likelihood of initiatives predicated around notices and transparency to address, by themselves, online privacy concerns.
