Ocular and Iris Recognition Baseline Algorithm

November 7, 2011
Author(s)
Yooyoung Lee, Ross J. Micheals, James J. Filliben, P J. Phillips, Hassan A. Sahibzada
Due to its distinctiveness, the human eye is a popular biometricv feature used to identity a person with high accuracy. The Grand Challenge in biometrics is to have an effective algorithm for subject verification or identification under a broad range of

Data Dependency on Measurement Uncertainties in Speaker Recognition Evaluation

November 3, 2011
Author(s)
Jin Chu Wu, Alvin F. Martin, Craig S. Greenberg, Raghu N. Kacker
The National Institute of Standards and Technology (NIST) has been conducting an ongoing series of Speaker Recognition Evaluations (SRE). Speaker detection performance is measured using a detection cost function defined as a weighted sum of the

Real-time Feedback for Usable Fingerprint Systems

October 11, 2011
Author(s)
Mary F. Theofanos, Brian C. Stanton, Yee-Yin Choong, Haiying Guan
Compared with traditional password and other identification methods, biometrics like face, iris, and fingerprint for automatic personal identification/verification have many advantages, and are increasingly gaining popularity in all kinds of applications

Iris Quality Calibration and Evaluation (IQCE): Evaluation Report

September 24, 2011
Author(s)
Elham Tabassi, Patrick J. Grother, Wayne J. Salamon
Iris is rapidly gaining acceptance and support as a viable biometric. Several large scale identity management applications are either using or considering iris as their secondary or primary biometric for verification. While there are several academic

ANSI/NIST-ITL 1-2011 Requirements and Conformance Test Assertions

September 16, 2011
Author(s)
Christofer J. McGinnis, Dylan J. Yaga, Fernando L. Podio
The current version of the ANSI/NIST-ITL standard "Data Format for the Interchange of Fingerprint, Facial & Other Biometric Information" is specified in two parts. Part 1, ANSI/NIST-ITL 1-2007, specifies the traditional format, and Part 2, ANSI/NIST-ITL 2

Standards and Biometrics

September 15, 2011
Author(s)
Bradford J. Wing
This paper addresses the importance of standards when implementing or using biometric systems. Standards have been developed to ensure that biometric systems can effectively and accurately meet users’ needs such as protecting data integrity, privacy, and

A Field Study of User Behavior and Perception in Smartcard Authentication

September 9, 2011
Author(s)
Emile L. Morse, Celeste L. Paul, Aiping L. Zhang, Yee-Yin Choong, Mary F. Theofanos
A field study of 24 participants over 10 weeks explored user behavior and perception in a smartcard authentication system. Ethnographic methods used to collect data included diaries, surveys, interviews, and field observations. We observed a number of

Defining AFIS Latent Print "Lights-Out"

September 8, 2011
Author(s)
Stephen Meagher, Vladimir N. Dvornychenko
The term "lights-out" for AFIS ten-print fingerprint operations has been around for many years and is generally understood to mean "no human intervention is involved." But is this term appropriate for AFIS latent print operations? This IR examines seven

NIST Special Databse 32 - Multiple Encounter Dataset II (MEDS-II)

July 21, 2011
Author(s)
Andrew P. Founds, Nick Orlans, Whiddon Genevieve, Craig I. Watson
This document and associated dataset is an update to the Multiple Encounter Dataset I (MEDS-I), originally published by the National Institute of Standards and Technology (NIST) in May 2010. The MEDS is a test corpus organized from an extract of submission

Conformance Test Architecture and Test Suite for ANSI/NIST-ITL 1-2007

June 22, 2011
Author(s)
Fernando L. Podio, Dylan J. Yaga, Christofer J. McGinnis
The Computer Security Division of NIST/ITL supports the development of biometric conformance testing methodology standards and other conformity assessment efforts through active technical participation in the development of these standards and the

Effects of JPEG 2000 Image Compression on 1000ppi Fingerprint Imagery

May 26, 2011
Author(s)
Shahram Orandi, John M. Libert, John Grantham, Kenneth Ko, Stephen S. Wood, Jin Chu Wu
This paper presents the findings of a study conducted to measure the impact of JPEG 2000 compression on fingerprint imagery at various levels of compression. The impact of compression is measured in terms of impact to both Galton and non-Galton based
