The performance of a biometric system that relies on a single biometric modality (eg,
fingerprints only) is often stymied by various factors such as poor data quality or limited …

Continuous authentication has been proposed as a possible approach for passive and
seamless user authentication, using sensor data comprising biometric, behavioral, and …

This paper presents a new approach to improve the performance of finger-vein identification
systems presented in the literature. The proposed system simultaneously acquires the finger …

This work evaluates the security strength of a smartphone-based gait recognition system
against zero-effort and live minimal-effort impersonation attacks under realistic scenarios …

Current smartphones generally cannot continuously authenticate users during runtime. This
poses severe security and privacy threats: A malicious user can manipulate the phone if …

Active authentication is the problem of continuously verifying the identity of a person based
on behavioral aspects of their interaction with a computing device. In this paper, we collect …

A widely accepted prediction is that computing will move to the background, weaving itself
into the fabric of our everyday living spaces and projecting the human user into the …

User identification and access control have become a high demand feature on mobile
devices because those devices are wildly used by employees in corporations and …

Most existing computer and network systems authenticate a user only at the initial login
session. This could be a critical security weakness, especially for high-security systems …

Human–Robot Interaction in Social Robotics explores important issues in designing a robot
system that works with people in everyday environments. Edited by leading figures in the …
