Abstract This paper provides an overview of the field of digital evidence and forensics from the perspective of the use of these fields in finance or digital crimes. Specifically, this paper investigates digital evidence and techniques for digital forensics in terms of how they complicate or facilitate the investigative process: how can forensic investigators apply new methods, given the rapidly expanding scope of cybercrime? How can new digital techniques facilitate investigations of computer fraud and other crimes? This paper considers computer and digital evidence from a forensic standpoint, considering how they have changed or rendered obsolete the already novel protocols for investigating such crimes. Conducting an in-depth review of…show more content…
S66). Garfinkel (2010) conceives of the years 1999 to 2007 as a so-called “golden age” of digital forensics: “During this time digital forensics became a kind of magic window that could see into the past (through the recovery of residual data that was thought to have been deleted) and into the criminal mind (through the recovery of email and instant messages). Network and memory forensics made it possible to freeze time and observe crimes as they were being committed even many months after the fact” (Garfinkel, 2010, p. S66). Therefore, the Golden Age created an important history of digital forensics – yet this vaunted past has been difficult for the present to keep up with, and Garfinkel is not certain that the future of digital forensics will match its past: “Without a clear strategy for enabling research efforts that build upon one another, forensic research will fall behind the market, tools will become increasingly obsolete, and law enforcement, military and other users of computer forensics products will be unable to rely on the results of forensic analysis” (Garfinkel, 2010, p. S64). Thus, it is clear that digital forensics is undergoing or must undergo a dramatic shift. Is this the case? The following literature review, which is subdivided into two main sections (i.e., statistical tools and processes and the future of digital forensics), seeks to evaluate the literature on this topic with an eye towards Garfinkel’s claims.
