Digital Forensics at the National Institute of Standards and Technology

April 1, 2008
Author(s)
James R. Lyle, Douglas R. White, Richard Ayers
There are three digital forensic science projects: National Software Reference Library (NSRL), Computer Forensic Tool Testing (CFTT), Computer Forensic Reference Data Sets (CFReDS) currently providing resources for the digital investigator underway at the

Characterization of 26 miniSTR loci for improved analysis of degraded DNA samples

January 25, 2008
Author(s)
Carolyn R. Steffen, Margaret C. Kline, Michael Coble, John M. Butler
An additional 20 novel mini-short tandem repeat (miniSTR) loci have been developed and characterized to aid in the analysis of degraded DNA samples. These new markers produce short PCR products in the target range of 50 150 base pairs (bp) by moving the

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

Toward Quantitative Fluorescence Measurements with Multicolor Flow Cytometry

December 28, 2007
Author(s)
Lili Wang, Adolfas Gaigalas, Gerald Marti, Fatima Abbasi, Robert A. Hoffman
A procedure is presented for calibrating the output of a multicolor flow cytometer in units of antibodies bound per cell (ABC). The procedure involves two steps. First, each of the fluorescence channels of the flow cytometer is calibrated using Ultra

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

Concordance Study Between the AmpFlSTR((R)) MiniFiler(TM) PCR Amplification Kit and Conventional STR Typing Kits

July 25, 2007
Author(s)
Carolyn R. Steffen, Margaret C. Kline, Julio J. Mulero, Robert E. Lagace, Chien-Wei Chang, Lori K. Hennessy, John M. Butler
The AmpFlSTR MiniFiler PCR Amplification kit developed by Applied Biosystems enables size reduction on eight of the larger short tandem repeat (STR) loci amplified in the Identifiler kit, which will aid recovery of information from highly degraded DNA

Forensic Techniques for Cell Phones

June 27, 2007
Author(s)
Shirley M. Radack
The data that is captured on mobile phones can be a source of valuable information to organizations that are investigating crimes, policy violations and other security incidents. The science of recovering digital evidence from mobile phones, using

Face Recognition Algorithms surpass humans matching faces across changes in illumination

May 15, 2007
Author(s)
P. Jonathon Phillips, Alice J. O'Toole, Fang Jian, Julianne Ayadd, Nils Penard, Herve Abdi
We compared the accuracy of eight state-of-the-art face recognition algorithms with human performance on the same task. Humans and algorithms determined whether two face images, taken under different illumination conditions, were pictures of the same

A 14-pixel, multiplexed array of gamma-ray microcalorimeters with 47 eV energy resolution at 103 keV

May 9, 2007
Author(s)
W.Bertrand (Randy) Doriese, Joel Ullom, James A. Beall, William Duncan, S. L. Ferreira, Gene C. Hilton, Rob Horansky, Kent D. Irwin, John Mates, Carl D. Reintsema, Leila R. Vale, Yizi Xu, Barry L. Zink, Andrew Hoover, Michael W. Rabin, Clifford R. Rudy, Duc Vo
We present a prototype for a high-energy-resolution, high-count-rate, gamma-ray spectrometer intended for nuclear forensics and international nuclear safeguards. The prototype spectrometer is an array of 14 transition-edge-sensor microcalorimeters with an

Cell Phone Forensic Tools: An Overview and Analysis Update

March 21, 2007
Author(s)
Richard Ayers, Wayne Jansen, Aurelien M. Delaitre, Ludovic Moenner
Cell phones and other handheld devices incorporating cell phone capabilities (e.g., Personal Digital Assistant (PDA) phones) are ubiquitous. Rather than just placing calls, certain phones allow users to perform additional tasks such as SMS (Short Message

Unique File Identification in the National Software Reference Library

October 24, 2006
Author(s)
Steven L. Mead
The National Software Reference Library (NSRL) provides a repository of known software, file profiles, and file signatures for use by law enforcement and other organizations involved with computer forensic investigations. This paper examines whether the

Guide to Integrating Forensic Techniques into Incident Response

September 1, 2006
Author(s)
Timothy Grance, Suzanne Chevalier, Karen A. Scarfone, Hung Dang
This publication is intended to help organizations in investigating computer security incidents and troubleshooting some information technology (IT) operational problems by providing practical guidance on performing computer and network forensics. The
