“Biometrics: technologies, challenges, and research directions”
Vincenzo Piuri, Università degli Studi di Milano, Italy
Abstract
Once typically used for critical applications and services, biometric technologies are now
pervasively permeating our everyday life enabling seamless and convenient
identification, authentication, as well as service assistance, from business to leisure.
Think of passport control, smart phone unlocking, voice command to home/IoT devices,
automatic photo tagging in social applications, all services based on underlying control
of biometric traits (e.g., face, finger, voice). Different biometric traits and technologies
have different characteristics, for instance, in terms of universality, uniqueness,
permanence, performance, and circumvention, making each of them suitable different
application scenarios. In this lecture I will illustrate the main biometrics techniques, their
strengths, limitations, and applications. I will also illustrate challenges and research
directions.
