Scope of Work
Digital evidence examinations require very specific hardware and software tools to find numerous types of digital evidence. Examiners, depending upon their specialties, may discover evidence and provide testimony concerning digital device examinations, network analysis, and examination and comparison of digitized numerals, images, analog/digital audio and video (which includes examinations such as authenticity, photogrammetry, and enhancement).
Computer forensics used to involve simply looking at individual computers that may have some connection to criminal activity. Now, network forensics is required to properly investigate and determine what happened, including mobile devices that provide fully networked computing technology in the palm of your hand. The analysis of audio recordings requires techniques and procedures that continue to be evolving areas of research. The advent of digital photography provides the potential to aid in the documentation of crime scenes and injuries.
Candidates for an apprenticeship program in digital and multimedia sciences should possess a minimum of a bachelor's degree, preferably in computer science, information technology, or engineering. In the United States, there are undergraduate degree programs with emphasis in digital forensics, computer forensics, and media forensics. There are also graduate degree and graduate certificate programs in these fields. Digital forensic examiners also may have various types of certifications. A certified professional not only possesses technical competency but also adheres to a strong code of ethics.
Digital forensic examiners are employed in both the public and private sector. Private practice consultants can be found in most major cities. Many large police organizations as well as most state and federal law enforcement agencies generally employ digital forensic experts. Scientists who specialize in the field of digital & multimedia sciences work or practice as computer-related crime investigators; computer specialists; image analysts/examiners; audio analysts/examiners; video analysts/examiners; speech scientists; and in facial identification/biometrics.
Many qualified practitioners are members of the American Academy of Forensic Sciences, International Association of Computer Investigative Specialists, the High Technology Crime Investigation Association, the International Society of Forensic Computer Examiners, the Audio Engineering Society, the International Association of Identification, the Law Enforcement & Emergency Services Video Association, the Institute of Electrical and Electronics Engineers, and other professional groups and societies.
