The Public Information Fallacy, Woodrow Hartzog

Faculty Scholarship

The concept of privacy in “public” information or acts is a perennial topic for debate. It has given privacy law fits. People struggle to reconcile the notion of protecting information that has been made public with traditional accounts of privacy. As a result, successfully labeling information as public often functions as a permission slip for surveillance and personal data practices. It has also given birth to a significant and persistent misconception — that public information is an established and objective concept.

In this article, I argue that the “no privacy in public” justification is misguided because nobody knows what “public” …

Privacy's Trust Gap, Neil M. Richards, Woodrow Hartzog

Faculty Scholarship

It can be easy to get depressed about the state of privacy these days. In an age of networked digital information, many of us feel disempowered by the various governments, companies, and criminals trying to peer into our lives to collect our digital data trails. When so much is in flux, the way we think about an issue matters a great deal. Yet while new technologies abound, our ideas and thinking — as well as our laws — have lagged in grappling with the new problems raised by the digital revolution. In their important new book, Obfuscation: A User’s Guide …

Surveillance As Loss Of Obscurity, Woodrow Hartzog, Evan Selinger

Faculty Scholarship

Everyone seems concerned about government surveillance, yet we have a hard time agreeing when and why it is a problem and what we should do about it. When is surveillance in public unjustified? Does metadata raise privacy concerns? Should encrypted devices have a backdoor for law enforcement officials? Despite increased attention, surveillance jurisprudence and theory still struggle for coherence. A common thread for modern surveillance problems has been difficult to find.

In this article we argue that the concept of ‘obscurity,’ which deals with the transaction costs involved in finding or understanding information, is the key to understanding and uniting …

The Case For Online Obscurity, Woodrow Hartzog, Frederic Stutzman

Faculty Scholarship

On the Internet, obscure information has a minimal risk of being discovered or understood by unintended recipients. Empirical research demonstrates that Internet users rely on obscurity perhaps more than anything else to protect their privacy. Yet, online obscurity has been largely ignored by courts and lawmakers. In this Article, we argue that obscurity is a critical component of online privacy, but it has not been embraced by courts and lawmakers because it has never been adequately defined or conceptualized. This lack of definition has resulted in the concept of online obscurity being too insubstantial to serve as a helpful guide …

Obscurity By Design, Woodrow Hartzog, Frederic D. Stutzman

Faculty Scholarship

Design-based solutions to confront technological privacy threats are becoming popular with regulators. However, these promising solutions have left the full potential of design untapped. With respect to online communication technologies, design-based solutions for privacy remain incomplete because they have yet to successfully address the trickiest aspect of the Internet — social interaction. This Article posits that privacy-protection strategies such as “Privacy by Design” face unique challenges with regard to social software and social technology due to their interactional nature.

This Article proposes that design-based solutions for social technologies benefit from increased attention to user interaction, with a focus on the …
