Statistical Considerations in Environmental Microbial Forensics

Bayesian-integrated microbial forensics.

In the aftermath of the 2001 anthrax letters, researchers have been exploring ways to predict the production environment of unknown-source microorganisms. Culture medium, presence of agar, culturing temperature, and drying method are just some of the broad spectrum of characteristics an investigator might like to infer. The effects of many of these factors on microorganisms are not well underst...

Courtroom Considerations in Digital Image Forensics

The manner in which results of digital image forensic investigations are presented in the courtroom can be positively or adversely affected by case law, federal rules and legislative acts, availability of discovery materials, tools, and the use of exhibits. Issues pertinent to effective and successful testimony are addressed, along with suggestions for improvement of methods. 1 Computer Forensi...

Statistical Tools for Digital Forensics

A digitally altered photograph, often leaving no visual clues of having been tampered with, can be indistinguishable from an authentic photograph. As a result, photographs no longer hold the unique stature as a definitive recording of events. We describe several statistical techniques for detecting traces of digital tampering in the absence of any digital watermark or signature. In particular, ...

Ubiquitous Computing for Microbial Forensics and Bioterrorism

abstract Microorganisms are ubiquitous in their presence. They are present in air, soil, water, and all kinds of living creatures. Varieties of microbes have been linked to diseases of humans, animals, and plants. Advances in molecular biology, electronics , nanotechnology, computer sciences, and information technology have made it possible to hybridize these to create ubiquitous devices and bi...
