Forensic science, more commonly known as forensics, is the application of sciences to answer questions of interest to a legal system. Forensics may be used to answer questions in relation to a crime or a civil action. Forensics encompasses the accepted scholarly or scientific methodology and norms under which the facts regarding an event, or an artifact, or some other physical item (such as a corpse) is ascertained as being the case. The concept, therefore, is related to the notion of authentication, whereby an interest outside of a legal form exists in determining whether an object is what it purports to be, or is alleged as being.
The word forensic comes from the Latin adjective forensis, meaning “of or before the forum.” In Roman times, a criminal charge meant presenting the case before a group of public individuals in the forum. Both the person accused of the crime and the accuser would give speeches based on their side of the story.
The individual with the best argument and delivery would determine the outcome of the case. This origin is the source of the two modern usages of the word as a form of legal evidence and as a category of public presentation.
Private investigators with specialized training and education may engage in various forms of forensic investigations such as:
- Forensic accounting
- Forensic computer software examination and analysis
- Document examinations
- Crime scene investigations
Following are resources for conducting investigations in this area:

- National Forensic Science Technology Center – Dedicated to supporting science laboratories achieve the highest possible quality of operations.
- Unshredder – Unshredder is a simple program that unleashes the power of a desktop computer to reduce the time consumed by investigators reconstructing shredded documentary evidence. Until now the only alternative to manual processing was to engage a third party to process the work on computers at their premises. By comparison to external processing of the evidence Unshredder reduces the turnaround time, keeps full control of the investigation in-house and there is less risk of a security risk or loss of the evidence. The original shreds remain unchanged from the process and the integrity of the original is captured electronically to be printed or dispatched electronically by wire or disc.
