Recently, it has been recognized that accessing information in the mitochondrial DNA (mtDNA) coding region can provide additional forensic discrimination with respect to the standard typing of the D-loop region, augmenting the sometimes rather limited
Based on auto- and cross-correlation functions (ACF and CCF), a new surface parameter called profile (or topography) difference, Ds, has been developed for quantifying differences between 2D profiles or between 3D topographies with a single number. When Ds

Cell phones and other handheld devices incorporating cell phone capabilities (e.g., Personal Digital Assistants (PDAs) phones) are ubiquitous. Rather than just placing calls, certain phones allow users to perform additional tasks such as SMS (Short Message

Computer simulation has been demonstrated to be credible, when properly applied, as a tool to help fill in critical details of a fire incident and to demonstrate the value of alternative building designs and fire safety measures. This poster presents the
This NIST Internal Report consists of two parts. Part A covers the planning, design, and specification of testing and reviewing the Software write block (SWB) support tools. Part B, which is a companion document, covers the test and code review support
Mobile handheld devices are becoming evermore affordable and commonplace in society. When they are involved in a security incident or crime, forensic specialists require tools that allow proper extraction and speedy examination of any digital evidence

A scanning magneto-resistive (MR) microscope was developed for high resolution imaging of magnetic tapes and digital media. Second harmonic detection was used to remove thermal anomalies. We were able to image sufficient lengths of tape for authentication

Forensic specialists periodically encounter unusual devices and new technologies normally not envisaged as having immediate relevance from a digital forensics perspective. The objective of the guide is twofold: to help organizations evolve appropriate

The typing of single nucleotide polymorphisms (SNPs) located throughout the mitochondrial genome (mtGenome) allows for differentiation between individulas possessing an identical HVa/HV2 sequence. A set of 11 SNPs selected for separating the most common
Adequate user authentication is a persistent problem, particularly with mobile devices such as Personal Digital Assistants (PDAs), which tend to be highly personal and at the fringes of an organization's influence. Yet these devices are being used

A bullet signature measurement system based on a stylus instrument was developed at the National Institute of Standards and Technology (NIST) for the signature measurements of NIST Rm (Reference Material) 8240 standard bullets. The standard bullets are
Genetic markers located on the Y chromosome are of increasing importance in human identity testing. In an effort to evaluate the forensic utility of Y chromosome single nucleotide polymorphism (SNP) markers, we constructed several novel multiplex allele
Multiplex analysis of genetic markers has become increasingly important in a number of fields including DNA diagnostics and human identity testing. Two methods for examination of single nucleotide polymorphisms (SNPs) with a potential for a high degree of
A multiplex PCR assay capable of amplifying 20 Y chromosome short tandem repeat (STR) markers simultaneously has been developed. These markers include all of the Y STRs that make up the extended haplotype used in Europe (DYS19, DYS385, DYS389I/II, DYS390

The Mixed Stain Study #3 (MSS3) interlaboratory challenge exercise evaluated the 2001 performance of STR multiplex DNA typing systems using a set of seven DNA extracts of designed concentration and composition. This initial report focuses on the linkages

The ability of various liquid extraction techniques to isolate the natural and artificial surface components of human scalp hair has been evaluated. These organic components largely consist of sebaceous lipids and hair treatment residues, and have shown

The NIST RM (Reference Material) 8240/8250 Standard Bullets and Casings Project aims to support the National Integrated Ballistics Information Network (NIBIN) in the U.S. Two prototype standard bullets were developed in 1998 with all six lands manufactured
