Selective and intelligent imaging using digital evidence bags

Selective and intelligent imaging using digital evidence bags

This paper defines what selective imaging is, and the types of selective imaging that can be performed. This is contrasted with intelligent imaging and the additional capabilities that have to be built into an imager for it to be ‘intelligent’. A selective information capture scenario is demonstrated using the digital evidence bag (DEB) storage format. A DEB is a universal container for digital...

Unification of Digital Evidence from Disparate Sources (Digital Evidence Bags)

This paper outlines a new approach to the acquisition and processing of digital evidence obtained from disparate digital devices and sources. To date the capture of digital based evidence has always been in its entirety from the source device and different methods and containers (file types) are used for different types of digital device (e.g. computer, PDA, mobile phone). This paper defines a ...

File System Support for Digital Evidence Bags

Secure, Audited Processing of Digital Evidence: Filesystem Support for Digital Evidence Bags

Traditional digital forensics methods capture, preserve, and analyze digital evidence in standard electronic containers: images of seized hard drives (e.g., created using the Unix dd command) are stored in regular files and documents are typically processed “as is”. Auditing of a digital investigation, from identification and seizure of evidence through duplication and investigation is essentia...

The Practice of Chest Radiography Using Different Digital Imaging Systems: Dose and Image Quality

Introduction: The study was undertaken to evaluate the practice of chest radiography using different digital imaging systems and its influence on dose and image quality.  Materials and Methods: The study was carried out in two hospitals from March 2016 to June 2016. Sixty ambulatory patients aged 21 to 60 years who were able to cooperate without difficulty and weighed between 60 to 80 kg were ...
