Biometric template protection is an important issue to be resolved so that practical biometric
authentication systems can be deployed. In this paper, we propose a non-invertible …

Unswerving information security mechanisms are the need of the hour for fighting the
escalating enormity of identity theft in our society. Besides cryptography being a dominant …

This work proposes a technique that improves fingerprint templates by merging and
averaging minutiae of multiple fingerprints. The weighted averaging scheme enables the …

With the growing concern for secure and private information protection, several issues
pertaining to the traditional biometric authentication system such as the reissuance of …

Cancelable (revocable) fingerprint templates have been proposed to protect fingerprint data.
However, many of them have incurred significant authentication performance degradation …

In this paper we focus on constructing k-Nearest Neighborhood Structure (k-NNS) for
minutiae points in a fingerprint image. For each minutiae point in a fingerprint, ak-NNS is …

This paper presents an approach to generate secure minutiae information in fingerprint
templates. Using triplets of minutia points, useful geometrical properties can be derived from …

Cancelable biometrics has become an indispensable technique during biometric
authentication. There have been several prior attempts to construct cancelable fingerprint …

Security of biometric templates in a fingerprint authentication system is highly critical
because the number of fingers of a person is limited and the raw fingerprints cannot be reset …

Biometric recognition systems are now commonplace. Although such systems have
improved security, they are vulnerable to a number of threats, including direct attacks to the …
