Digital & Multimedia Sciences
The advent of digital photography with its potential to
aid in the documentation of crime scenes and injuries, as
well as to speed up all aspects of photography from mug
shots to autopsy, creates an important area of research and
development. Such photographs present many challenges and
the burdens of easy alteration must be balanced with the
benefits of speed and economy. These issues extend to the
computer imaging of crime scenes, suspect composites, and
victim characteristics for possible identification. The
reliability and scientific accuracy of computer recreations
of crime scene events also remains an area for much-needed
research.
There are several specialties in Digital & Multimedia
Sciences. Digital & Multimedia Sciences professionals help
develop the scientific foundations for the practice of
digital forensics, including research and publication, or
they may manage digital forensic laboratories.
The forensic sciences utilize multitudes of instruments,
chemical tests, measuring devices, and numerous specialty
tools to assist in forensic examinations. Laboratory
accreditation is a mechanism for achieving quality
assurance. Digital evidence examinations require very
specific hardware and software tools to find numerous types
of latent digital evidence. Digital forensic laboratories
that are accredited require annual proficiency tests, like
all other forensic specialties.
Examiners, depending upon their specialties, may discover
and prove facts concerning the following:
• Digital device examinations
• Network analysis
• Examination and comparison of digitized numerals,
images,
and analog/digital audio and video (which
includes
examinations such as authenticity,
photogrammetry and
enhancement)
The work of the examiner might address some of the following
questions:
• What files have been deleted from the digital device?
• Can a timeline of activity be established on this
system?
• What other digital devices have been connected to
this
system?
• Was this system attacked or modified by someone
over the
network?
• Can a remote system or user be located or identified?
• What sites on the internet were visited by this system?
• Was this audio recording altered?
• Can this video recording be enhanced to help identify
someone?
• Can the physical characteristics of an object in a
photograph be determined?
