Diffensive Privacy

A Response to the Criticisms of Fool’s Gold: An Illustrated Critique of Differential Privacy By Jane Bambauer and Krish Muralidhar Two years ago, we coauthored an article that challenged the popular enthusiasm for Differential Privacy. Differential Privacy is a technique that permits researchers to query personal data without risking the privacy of the data subjects. It […]

Tyler Broker on Expanding the “No Speculation” Test in Free Speech Cases

My friend and former student Tyler Broker is publishing an interesting and provocative free speech essay in the Gonzaga Law Review. I’ve asked Tyler to prepare a guest blog post. A draft of the full essay is available here. Who would be so base as to challenge the conventional wisdom that commercial speakers receive less […]

Is De-Identification Dead Again?

Earlier this year, the journal Science published a study called “Unique in the Shopping Mall: On the Reidentifiability of Credit Card Metadata” by Yves-Alexandre de Montjoye et al. The article has reinvigorated claims that deidentified research data can be reidentified easily. These claims are not new, but their recitation in a vaunted science journal led […]

Reporting Fail: The Reidentification of Personal Genome Project Participants

Last week, a Forbes article by Adam Tanner announced that a research team led by Latanya Sweeney had re-identified “more than 40% of a sample of anonymous participants” in Harvard’s Personal Genome Project. Sweeney is a progenitor of demonstration attack research. Her research was extremely influential during the design of HIPAA, and I have both […]

Privacy Law in Sixty Seconds (or so)

I am occasionally struck by my good fortune to write in an area that has such a supportive community. Much credit is due to the influence, ingenuity, and incessant hard work of Paul Schwartz and Dan Solove. Invariably, every privacy scholar has benefited from Dan’s and Paul’s support. This promotional video for their informal treatise Privacy Law […]

Do Reactions To Drug-Sniffing Dogs Say More About Drug Policy Than Privacy?

In Florida v. Jardines, the U.S. Supreme Court will determine whether the sniff of a trained narcotics dog at the front door of a person’s home constitutes a Fourth Amendment search. This is very exciting for privacy scholars because it presents two possible shifts in Fourth Amendment jurisprudence. First, the court might further expand Justice […]

Abusing Anonymity

The sexual assault case against former IMF head Dominique Strauss-Kahn is famously falling apart; the alleged victim faces credibility problems from lying on her asylum application, among other things. Here in New York City, the district attorney, Cy Vance, is under considerable scrutiny for his decision to charge Strauss-Kahn in the first place. Unsurprisingly, the […]

Ohm on Bambauer on Cybersecurity

I will save my co-blogger Derek Bambauer from tooting his own horn by tooting it for him: Paul Ohm has written a very lovely review on Jotwell of Derek’s forthcoming law review article, Condundrum. From Paul’s review: I have never felt entirely satisfied by a single work about cybersecurity, at least not until now. Derek […]

Is the DMCA Still Controversial?

It’s easy to understand why the Digital Millennium Copyright Act caused an uproar when it was enacted twelve years ago. Nominally in the name of deterring piracy, Congress acted directly to regulate the creation, use, and distribution of the sorts of tools that potentially could be used to infringe copyright. As written, however, the statute […]

Well, Someone at Nixon Peabody Isn’t a Winner…

There has been extensive commentary and derision around the legal blogosphere about a preposterous corporate song commissioned by the law firm of Nixon Peabody, and then the firm’s subsequent efforts to threaten those who mocked it with IP saber-rattling. David Lat first posted the song, and here he summarizes the ensuing flapdoodle. A very funny […]
