T-15: Biometric System Security

Monday Afternoon, March 31
14:00 - 17:00

Presented by

Anthony Vetro, Mitsubishi Electric Research Laboratories, uSA and Nasir Memon, Polytechnic University, USA

Abstract

This tutorial will address the area of biometric security. We will motivate and describe the problem, with particular emphasis on the specific challenges for secure storage and exchange of biometrics. We will also review various architectures that could be used for secure biometric authentication and describe systems in which a secure biometric could be used for encryption. We will then describe the performance measures that are used to evaluate the effectiveness of a particular approach - both robustness and security aspects will be examined. The various approaches for securing biometric data will then be discussed. The merits and drawbacks of the different techniques will also be covered. We will conclude this session with a discussion on the status of biometric security and open issues.
