Two goals of this study are to determine the extent of fingerprint distortion on recognition
performance and establish if varying levels of distortion in acquired fingerprints linearly …

Challenges to contextual filtering techniques include difficulties in estimating orientation field
in poor quality images and subsequently failure to extract ridges reliably in large regions of …

The widespread deployment of Automated Fingerprint Identification Systems (AFIS) in law
enforcement and border control applications has heightened the need for ensuring that …

Biometric systems are increasingly replacing traditional password-and token-based
authentication systems. Security and recognition accuracy are the two most important …

Despite the long history of using fingerprints, some key concerns still remain about the
accuracy of identification, the usability of fingerprint systems in different situations, and …

One of the potential vulnerabilities in a biometric system is the leakage of biometric template
information, which may lead to serious security and privacy threats. Most of the available …

The first live scan fingerprint readers introduced in 1988 were difficult to use and had many
problems when compared to the inexpensive and relatively small sensors currently …

Fingerprints are the most widely used physiological identifier in biometric recognition
systems. Consequently, the domain of automated fingerprint matching is of utmost …

Security of biometric templates stored in a system is important because a stolen template
can compromise system security as well as user privacy. Therefore, a number of secure …

Fingerprint recognition has been successfully used in law enforcement and forensics to
identify suspects and victims for over a century. Recent advances in automated fingerprint …
