Recent advances in biometric recognition and the increasing use of biometric data prompt
significant privacy challenges associated with the possible misuse, loss, or theft of biometric …

Biometrics now play a crucial role in user identification and authentication. However, storing
biometric features in plaintext and conducting authentication without protection pose a risk of …

In this correspondence, we analyze the vulnerabilities of biometric authentication protocols
with respect to user and data privacy. The goal of an adversary in such context is not to …

We design privacy-preserving protocols for scaled Manhattan and scaled Euclidean
verifiers, secure against malicious clients and honest-but-curious server. We then augment …

In biometric authentication protocols, a user is authenticated or granted access to a service if
her fresh biometric trait matches the reference biometric template stored on the service …

We introduce a new cryptographic primitive for noise tolerant template security. Our primitive
consists of two algorithms. The first algorithm extracts a noise tolerant and secure template …

As many vulnerabilities of one-time authentication systems have already been uncovered,
there is a growing need and trend to adopt continuous authentication systems. Biometrics …

In this paper, we study the security of two recently proposed privacy-preserving biometric
authentication protocols that employ packed somewhat homomorphic encryption schemes …

In this paper, a new method for secure remote biometric authentication preventing the
vulnerability of compromised biometrics is presented. The idea is based on a public-key …

In an increasing number of image and video processing problems, cryptographic techniques
are used to enforce content access control, identity verification and authentication, and …
