Using Digital Forensics for Investigations: A Question of Trust

By Gov CIO Outlook | Friday, February 08, 2019

Today, digital technology has been used to secure convictions and prove innocence. The world market of digital forensics has segmented the regions of South America, North America Middle East, Asia, and Europe. Research Report Insights (RRI), the digital forensics market stood around the valuation value of around $2.87 billion in the year 2016. It is estimated to have around $6.65 by the year 2025. Compound Annual Growth Rate (CAGR) has increased by 9.7 percent between 2015 and 2017.

As fraudsters have increased technology usage, the police also tend to keep up with the advancements like a digital forensic unit. For instance, in serious road collisions, the phone activity can be scrutinized using the digital forensic approach to know the details about the victim. In criminal and family-related cases, identification through DNA analysis is essential. The STR typing has now overtaken DNA typing and parentage testing.

The STR typing helps in monitoring bone marrow engraftment following the transplantation. These days, digital forensic methods have been using STR typing instead of forensic DNA typing.  While using DNA typing, analytical methods for smaller fragments have been increased. In order to reduce the fragments, the standard STR method has been used in the United States. In U.S. 15, loci were used to compare the DNA.

Fingerprint evident is the next high profile involved in the digital forensic methods that rests on the principle of friction ridge patterns. Experts declare a match when the point goes 12 in common. There are several digital forensic methodologies used in the sector. The cybercrime lab at Computer Crime and Intellectual Property Section has the flowchart that explains the methods and the steps involved in forensic methods. The key elements of computer forensics involve scientific methods, collection, and preservation, validation, identification, documentation, and presentation.

The research that took place at the University of York in England has evident information regarding the accuracy of digital forensic methods. International standards have been created in the testing laboratories that use scientific techniques to test metals and chemical compounds.
