This paper addresses privacy leakage in biometric secrecy systems. Four settings are
investigated. The first one is the standard Ahlswede-Csiszar secret-generation setting in …

In this paper, we analyze two types of biometric identification systems with protected
templates that also support authentication. In the first system, two terminals observe …

In this review, biometric systems are studied from an information theoretical point of view. In
the first part biometric authentication systems are studied. The objective of these systems is …

In the XXI st century, there is a strong interest on privacy issues. Technology permits
obtaining personal information without individuals' consent, computers make it feasible to …

Modern biometrics delivers an enhanced level of security by means of a “proof of property”.
The design and deployment of a biometric system, however, hide many pitfalls, which, when …

Systems employing biometric traits for people authentication and identification are
witnessing growing popularity due to the unique and indissoluble link between any …

This is the first part of a two-part paper on the information theoretic study of biometric security
systems. In this paper, the design of single-use biometric security systems is analyzed from …

Biometric security systems are studied from an information theoretic perspective. A
fundamental tradeoff between privacy, measured by the normalized equivocation rate of the …

This is the second part of a two-part paper on the information theoretic study of biometric
security systems. In this paper, the performance of reusable biometric security systems, in …

Biometric technologies promise many benefits, including stronger user authentication,
greater user convenience, improved security, and operational efficiencies. These …
