Assessing Face Acquisition

September 15, 2008
Author(s)
Mary F. Theofanos, Brian C. Stanton, Charles L. Sheppard, Ross J. Micheals, John M. Libert, Shahram Orandi
The requirements necessary for taking a successful face picture are arguably the least constrained of any biometric. The camera must be operational, and the subject must be illuminated sufficiently and facing the camera. Yet, a significant portion of the

Usability and Biometrics: Ensuring Successful Biometric Systems

June 11, 2008
Author(s)
Mary F. Theofanos, Brian C. Stanton, Cari Wolfson
The National Institute of Standards and Technology (NIST)Visualization and Usability Gropu initiated a Usability and Biometrics effort to focus on the users and human factors of biometric systems. The goal of this effort has been to conduct research to

Subspace Linear Discriminant Analysis for Face Recognition

June 10, 2008
Author(s)
W Zhao, R Chellappa, P. Jonathon Phillips
In this correspondence, we describe a holistic face recognition method based on subspace Linear Discriminant Analysis (LDA). Like existing methods, this method consists of two steps: first, the face image is projected into a face subspace via Principal

Usability Testing of Height and Angles of Ten-Print Fingerprint Capture

May 11, 2008
Author(s)
Mary F. Theofanos, Brian C. Stanton, Charles L. Sheppard, Ross J. Micheals, John W. Wydler II, Nien F. Zhang, Lawrence Nadel, William Rubin
As the deployment of biometric technologies such as fingerprints has become more widespread in government applications there is an increased awareness of the human-computer interaction that such technologies involve. User behavior can impact operational

Infrastructure System Design Methodology for Smart ID Cards Deployment

April 19, 2008
Author(s)
Ramaswamy Chandramouli
With the increasing use of smart cards for identity verification of individuals, it has become imperative for organizations to properly design and engineer the expensive infrastructure system that supports smart card deployment. Apart from sound system

Overcoming Impediments to Cell Phone Forensics

January 16, 2008
Author(s)
Wayne Jansen, Aurelien M. Delaitre, Ludovic Moenner
Cell phones are an emerging but rapidly growing area of computer forensics. While cell phones are becoming more like desktop computers functionally, their organization and operation are quite different in certain areas. For example, most cell phones do not

Latent Fingerprint Performance Modeling

January 14, 2008
Author(s)
Vladimir N. Dvornychenko
This paper describes aspects of work done at NIST, in concert with the latent fingerprint community, toward achieving a partial lights-out latent fingerprint processing capability. The initial steps are to quantify performance over a cross-section of

Smart Cards for Mobile Devices

December 3, 2007
Author(s)
Wayne Jansen, Serban I. Gavrila, Clement Seveillac
While mobile handheld devices provide productivity benefits, they also pose new risks. User authentication is the best safeguard against the risk of unauthorised use and access to a device¿s contents. This paper describes two novel types of Smart Card (SC)

Secure Biometric Match-on-Card Feasibility Report

November 30, 2007
Author(s)
David A. Cooper, Trung-Hung Dang, Philip Lee, William I. MacGregor, Ketan Mehta
FIPS 201, "Personal Identity Verification (PIV) of Federal Employees and Contractors," and its associated special publications define a method to perform biometric match-off-card authentication of a PIV cardholder when the PIV card is inserted into a

Reference Material for Assessing Forensic SIM Tools

October 1, 2007
Author(s)
Wayne Jansen, Aurelien M. Delaitre
Subscriber Identity Modules (SIMs) are a fundamental standardized component of most cell phones used worldwide. A SIM can be removed from a phone handset and inserted into another, allowing users to port identity, personal information, and service between
