Self Incrimination And Cryptographic Keys, Gregory S. Sergienko

Greg Sergienko

Modern cryptography can make it virtually impossible to decipher documents without the cryptographic key thus making the availability of the contents of those documents depend on the availability of the key. This article examines the Fourth and Fifth Amendments' protection against the compulsory production of the key and the scope of the Fifth Amendment immunity against compelled production. After analyzing these questions using prevailing Fourth and Fifth Amendment jurisprudence, I shall describe the advantages of a privacy-based approach in practical and constitutional terms.

Amicus Brief -- Riley V. California And United States V. Wurie, Charles E. Maclean, Adam Lamparello

Adam Lamparello

Warrantless searches of cell phone memory—after a suspect has been arrested, and after law enforcement has seized the phone—would have been unconstitutional at the time the Fourth Amendment was adopted, and are unconstitutional now. Simply stated, they are unreasonable. And reasonableness—not a categorical warrant requirement—is the “touchstone of Fourth Amendment analysis.”

Katz On A Hot Tin Roof: The Reasonable Expectation Of Privacy Is Rudderless In The Digital Age Unless Congress Continually Resets The Privacy Bar, Charles E. Maclean

Charles E. MacLean

The Katz reasonable expectation of privacy doctrine has lasting relevance in the digital age, but that relevance must be carefully and clearly guided in great detail by Congressional and state legislative enactments continually resetting the privacy bar as technology advances. In that way, the Katz “reasonableness” requirements are actually set by the legislative branch, thereby precluding courts from applying inapposite analogies to phone booths, cigarette packs, and business records. Once legislation provides the new contours of digital privacy, those legislative contours become the new “reasonable.”

This article calls upon Congress, and to a lesser extent, state legislatures, to control that …

Immigration Policing And Federalism Through The Lens Of Technology, Surveillance, And Privacy, Anil Kalhan

Anil Kalhan

With the deployment of technology, federal programs to enlist state and local police assistance with immigration enforcement are undergoing a sea change. For example, even as it forcefully has urged invalidation of Arizona’s S.B. 1070 and similar state laws, the Obama administration has presided over the largest expansion of state and local immigration policing in U.S. history with its implementation of the “Secure Communities” program, which integrates immigration and criminal history database systems in order to automatically ascertain the immigration status of every individual who is arrested and booked by state and local police nationwide. By 2012, over one fifth …

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

David C. Gray

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 …
