Many problems have arisen in the last decade concerning the authenticity of evidence gathered at a crime scene. The importance of this, is the evidence can be easily tampered with, and even destroyed, by a criminal suspect or someone else. Forensic analysis is known as the investigation of techniques to identify, collect, examine and preserve digital information (Cain). This process is often harder than one would think seeing as the evidence can be compromised easily. This leads to lack of what the Forensic officer is searching for, because the evidence can be meddled with and even changed, so thats why it is necessary to research possible alternatives. The purpose of this literature review is to provide an overview for Forensic Analysts who are interested in the protection of their evidence. In order to prevent this unfortunate complication, Analysts must try within their power to make sure the evidence hasn’t been tampered with, find as …show more content…
