Several issues related to the vulnerability of fingerprint recognition systems to attacks have
been highlighted in the biometrics literature. One such vulnerability involves the use of …

Nowadays, fingerprint biometrics is widely used in various applications, varying from
forensic investigations and migration control to access control as regards security sensitive …

The primary purpose of a fingerprint recognition system is to ensure a reliable and accurate
user authentication, but the security of the recognition system itself can be jeopardized by …

User authentication systems (in short authentication systems) have wide utilization in our
daily life. Unfortunately, existing authentication systems are prone to various attacks while …

Biometric authentication systems are quite vulnerable to sophisticated spoofing attacks. To
keep a good level of security, reliable spoofing detection tools are necessary, preferably …

Biometric-based authentication is gaining increasing attention for wearables and mobile
applications. Meanwhile, the growing adoption of sensors in wearables also provides …

Earables (ear wearables) are rapidly emerging as a new platform encompassing a diverse
range of personal applications. The traditional authentication methods hence become less …

In recent years, fingerprint authentication systems have been extensively deployed in
various applications, including attendance systems, authentications on smartphones, mobile …

Fingerprint liveness detection consists in verifying if an input fingerprint image, acquired by a
fingerprint verification system, belongs to a genuine user or is an artificial replica. Although …

We propose a new local descriptor for fingerprint liveness detection. The input image is
analyzed both in the spatial and in the frequency domain, in order to extract information on …
