Image Specific Error Rate: A Biometric Performance Metric<br />
Tabassi, Elham, NIST<br />
Image-specific false match and false non-match error rates are defined by inheriting concepts from the biometric zoo. These<br />
metrics support failure mode analyses by allowing association of a covariate (e.g., dilation for iris recognition) with a matching<br />
error rate without having to consider the covariate of a comparison image. Image-specific error rates are also useful in detection<br />
of ground truth errors in test datasets. Images with higher image-specific error rates are more ``difficult’’ to recognize,<br />
so these metrics can be used to assess the level of difficulty of test corpora or partition a corpus into sets with varying level<br />
of difficulty. Results on use of image-specific error rates for ground-truth error detection, covariate analysis and corpus partitioning<br />
is presented.<br />

We propose in this paper a low cost multimodal biometric system combining keystroke dynamics and 2D face recognition.<br />
The objective of the proposed system is to be used while keeping in mind: good performances, acceptability, and espect of<br />
privacy. Different fusion methods have been used (min, max, mul, svm, weighted sum configured with genetic algorithms,<br />
and, genetic programming) on the scores of three keystroke dynamics algorithms and two 2D face recognition ones. This<br />
multimodal biometric system improves the recognition rate in comparison with each individual method. On a chimeric database<br />
composed of 100 individuals, the best keystroke dynamics method obtains an EER of 8.77%, the best face recognition<br />
one has an EER of 6.38%, while the best proposed fusion system provides an EER of 2.22%.<br />

Extended fingerprint features such as pores, dots and incipient ridges have been increasingly attracting attention from researchers<br />
and engineers working on automatic fingerprint recognition systems. A variety of methods have been proposed to<br />
combine these features with the traditional minutiae features. This paper comparatively analyses the parallel and hierarchical<br />
fusion approaches on a high resolution fingerprint image dataset. Based on the results, a novel and more effective hierarchical<br />
approach is presented for combining minutiae, pores, dots and incipient ridges.<br />

Feature Band Selection for Multispectral Palmprint Recognition<br />

Palm print is a unique and reliable biometric characteristic with high usability. Many palm print recognition algorithms and<br />
systems have been successfully developed in the past decades. Most of the previous works use the white light sources for illumination.<br />
Recently, it has been attracting much research attention on developing new biometric systems with both high<br />
accuracy and high anti-spoof capability. Multispectral palm print imaging and recognition can be a potential solution to such<br />
systems because it can acquire more discriminative information for personal identity recognition. One crucial step in developing<br />
such systems is how to determine the minimal number of spectral bands and select the most representative bands to<br />
build the multispectral imaging system. This paper presents preliminary studies on feature band selection by analyzing hyper<br />
