The Automated Fourth Amendment, Maneka Sinha

Faculty Scholarship

Courts routinely defer to police officer judgments in reasonable suspicion and probable cause determinations. Increasingly, though, police officers outsource these threshold judgments to new forms of technology that purport to predict and detect crime and identify those responsible. These policing technologies automate core police determinations about whether crime is occurring and who is responsible. Criminal procedure doctrine has failed to insist on some level of scrutiny of—or skepticism about—the reliability of this technology. Through an original study analyzing numerous state and federal court opinions, this Article exposes the implications of law enforcement’s reliance on these practices given the weighty interests …

When Enough Is Enough: Location Tracking, Mosaic Theory, And Machine Learning, Steven M. Bellovin, Renée M. Hutchins, Tony Jebara, Sebastian Zimmeck

Faculty Scholarship

Since 1967, when it decided Katz v. United States, the Supreme Court has tied the right to be free of unwanted government scrutiny to the concept of reasonable xpectations of privacy.^[1] An evaluation of reasonable expectations depends, among other factors, upon an assessment of the intrusiveness of government action. When making such assessment historically the Court has considered police conduct with clear temporal, geographic, or substantive limits. However, in an era where new technologies permit the storage and compilation of vast amounts of personal data, things are becoming more complicated. A school of thought known as “mosaic theory” …

Big Data's Other Privacy Problem, James Grimmelmann

Faculty Scholarship

Big Data has not one privacy problem, but two. We are accustomed to talking about surveillance of data subjects. But Big Data also enables disconcertingly close surveillance of its users. The questions we ask of Big Data can be intensely revealing, but, paradoxically, protecting subjects' privacy can require spying on users. Big Data is an ideology of technology, used to justify the centralization of information and power in data barons, pushing both subjects and users into a kind of feudal subordination. This short and polemical essay uses the Bloomberg Terminal scandal as a window to illuminate Big Data's other privacy …

Addressing The Harm Of Total Surveillance: A Reply To Professor Neil Richards, Danielle Keats Citron, David C. Gray

Faculty Scholarship

In his insightful article The Dangers of Surveillance, 126 HARV. L. REV. 1934 (2013), Neil Richards offers a framework for evaluating the implications of government surveillance programs that is centered on protecting "intellectual privacy." Although we share his interest in recognizing and protecting privacy as a condition of personal and intellectual development, we worry in this essay that, as an organizing principle for policy, "intellectual privacy" is too narrow and politically fraught. Drawing on other work, we therefore recommend that judges, legislators, and executives focus instead on limiting the potential of surveillance technologies to effect programs of broad and indiscriminate …

A Shattered Looking Glass: The Pitfalls And Potential Of The Mosaic Theory Of Fourth Amendment Privacy, David C. Gray, Danielle Keats Citron

Faculty Scholarship

On January 23, 2012, the Supreme Court issued a landmark non-decision in United States v. Jones. In that case, officers used a GPS-enabled device to track a suspect’s public movements for four weeks, amassing a considerable amount of data in the process. Although ultimately resolved on narrow grounds, five Justices joined concurring opinions in Jones expressing sympathy for some version of the “mosaic theory” of Fourth Amendment privacy. This theory holds that we maintain reasonable expectations of privacy in certain quantities of information even if we do not have such expectations in the constituent parts. This Article examines and …

Privacy, Antitrust, And Power, Frank Pasquale

Faculty Scholarship

When a dominant internet service collects information about its users, the situation is so far from the usual arm’s-length market transaction that neoclassical economic analysis is misleading. “Lack of surveillance” is not a product that individuals have varying preferences for and purchase accordingly. Rather, surveillance is an inevitable concomitant of life online. We need to tame the power that surveillance entails, rather than continuing to pursue illusory, surveillance-free alternatives on the platform level.

To the extent a company creates profiles of individuals and collects data on them, a third party ought to be collecting reports from the company on how …

Fighting Cybercrime After United States V. Jones, David C. Gray, Danielle Keats Citron, Liz Clark Rinehart

Faculty Scholarship

In a landmark non-decision last term, five Justices of the United States Supreme Court would have held that citizens possess a Fourth Amendment right to expect that certain quantities of information about them will remain private, even if they have no such expectations with respect to any of the information or data constituting that whole. This quantitative approach to evaluating and protecting Fourth Amendment rights is certainly novel and raises serious conceptual, doctrinal, and practical challenges. In other works, we have met these challenges by engaging in a careful analysis of this “mosaic theory” and by proposing that courts focus …

Federal Search Commission? Access, Fairness, And Accountability In The Law Of Search, Oren Bracha, Frank Pasquale

Faculty Scholarship

Should search engines be subject to the types of regulation now applied to personal data collectors, cable networks, or phone books? In this article, we make the case for some regulation of the ability of search engines to manipulate and structure their results. We demonstrate that the First Amendment, properly understood, does not prohibit such regulation. Nor will such interventions inevitably lead to the disclosure of important trade secrets.

After setting forth normative foundations for evaluating search engine manipulation, we explain how neither market discipline nor technological advance is likely to stop it. Though savvy users and personalized search may …

Reservoirs Of Danger: The Evolution Of Public And Private Law At The Dawn Of The Information Age, Danielle Keats Citron

Faculty Scholarship

A defining problem at the dawn of the Information Age will be securing computer databases of ultra-sensitive personal information. These reservoirs of data fuel our Internet economy but endanger individuals when their information escapes into the hands of cyber-criminals. This juxtaposition of opportunities for rapid economic growth and novel dangers recalls similar challenges society and law faced at the outset of the Industrial Age. Then, reservoirs collected water to power textile mills: the water was harmless in repose but wrought havoc when it escaped. After initially resisting Rylands v. Fletcher’s strict liability standard as undermining economic development, American courts …
