Multimodal biometric systems are commonly believed to be more robust to spoofing attacks
than unimodal systems, as they combine information coming from different biometric traits …

Biometrics, referred as the science of recognizing an individual based on his or her physical
or behavioral traits, has been widely employed as a security system in the awake of latest …

Recent works have investigated the robustness to spoofing attacks of multi-modal biometric
systems in parallel fusion mode. Contrary to a common belief, it has been shown that they …

Multimodal biometric systems have consistently presented better recognition rates when
compared to the unimodal systems that compose them. A common claim is that they also …

In certain applications based on multimodal interaction it may be crucial to determine not
only what the user is doing (commands), but who is doing it, in order to prevent fraudulent …

Anti-spoofing is attracting growing interest in biometrics, considering the variety of fake
materials and new means to attack biometric recognition systems. New unseen materials …

Prior work has shown that multibiometric systems are vulnerable to presentation attacks,
assuming that their matching score distribution is identical to that of genuine users, without …

While more accurate and reliable than ever, the trustworthiness of biometric verification
systems is compromised by the emergence of spoofing attacks. Responding to this threat …

In biometric systems, the threat of “spoofing”, where an imposter will fake a biometric trait,
has lead to the increased use of multimodal biometric systems. It is assumed that an …

Security is “freedom from risk or danger”, while computer and data security is “the ability of a
system to protect information and system resources with respect to confidentiality and …
