An Approach to Biometric Identity Management Using Low Cost Equipment

Abstract

Digital identities are becoming increasingly popular. Professional implementation relies upon a secure embedded system and two-factor authentication for managing the important credentials. Although biometric user authentication is sometimes employed, it is still costly and difficult for the average user. The hardware currently available does not always use embedded processing or include a certified controller. We designed a system that allows digital identity management using two-factor authentication. This system considers typically existing IT infrastructure, relies upon on-card-biometric-comparison and operates from a portable device transparent to the host system.
