Identification, Individualization, Uniqueness, David H. Kaye Mar 2016

Identification, Individualization, Uniqueness, David H. Kaye

David Kaye

Criminalists and many forensic scientists concerned with the identification of trace evidence have distinguished between identification and individualization, but they have not distinguished as precisely between individualization and uniqueness. This paper clarifies these terms and discusses the relationships among identification, individualization, and uniqueness in forensic-science evidence.


A Fourth Amendment Theory For Arrestee Dna And Other Biometric Databases, David H. Kaye Mar 2016

A Fourth Amendment Theory For Arrestee Dna And Other Biometric Databases, David H. Kaye

David Kaye

Routine DNA sampling following a custodial arrest process is now the norm in many jurisdictions, but is it consistent with the Fourth Amendment? The few courts that have addressed the question have disagreed on the answer, but all of them seem to agree on two points: (1) the reasonableness of the practice turns on a direct form of balancing of individual and governmental interests; and (2) individuals who are convicted — and even those who are merely arrested — have a greatly diminished expectation of privacy in their identities. This Article disputes these propositions and offers an improved framework for …

Biometrics: Weighing Convenience And National Security Against Your Privacy, Lauren D. Adkins Jan 2007

Biometrics: Weighing Convenience And National Security Against Your Privacy, Lauren D. Adkins

Michigan Telecommunications & Technology Law Review

The biometric identifier relies on an individual's unique biological information such as a hand, iris, fingerprint, facial or voice print. When used for verification purposes, a "one-to-one" match is generated in under one second. Biometric technology can substantially improve national security by identifying and verifying individuals in a number of different contexts, providing security in ways that exceed current identification technology and limiting access to areas where security breaches are especially high, such as airport tarmacs and critical infrastructure facilities. At the same time, a legitimate public concern exists concerning the misuse of biometric technology to invade or violate personal …

Then, the court withdrew the opinion. This article reproduces an exchange of notes on the initial opinion submitted by five law professors.
