The Value Of Computer Forensic Analysis

Different criminal investigations will require different kinds of computer forensic analysis. Thus, between homicide and corporate date theft, the procedure will vary a lot. There are common features shared as part of the legal system, or some form of common grounds. First of all, finding evidence that can be accepted in a court of law is not enough. Before getting to court, a computer forensics investigator has to make sure that he/she extracts and preserves evidence, preventing decay or damage that would make it unusable. Furthermore, the forensic analysis actually starts when the crime scene has been thoroughly searched by the forensic experts.

Computer forensic analysis can reveal a whole range of traces and evidences that cannot be identifiable on the spot and with regular means. Thus, fingerprint matching, facial portraits from DNA prints, analysis of minerals, textiles, germs and bacteria as well as other elements collected on the the site of a crime get under micro-scrutiny to be proved or improved as relevant or irrelevant for criminal prosecution. Medical exams are also commonly necessary when there are victims involved in a certain crime; medical experts will perform such forensic analysis, giving the answer to the legal questions.

It is the popular belief that a forensic analysis necessarily involves manslaughter or other very tragic crime but forensic analysis serves for a very large number of investigations. Where there is a work accident, a fire, a case of identity or data theft, situations of financial fraud and so on, a good forensic analysis could reveal the culprit, and even help to reducing loss and recovering data. The criminal justice picture we tend to attribute to a regular forensic analysis results from the impact that police TV series such as CSI have on popular culture.

Science TV channels like Discovery for instance also allow an insight of a computer forensic investigation, but they surely present the most spectacular of cases. It seems like there is an international trend to be fascinated with the sensationalism of violence and ever younger people are psychologically affected by such trends in the group subconscious. Nobody should interfere with forensic investigation because without knowing it one could destroy or ruin evidence and affect the very course of a trial. Let’s leave the drama aside and allow the professionals to do their jobs. A forensic analysis does not make the subject of amateurish investigation as it is a very complex scientific procedure that requires special training.
