On the Benefits of Information Retrieval and Information Extraction Techniques Applied to Digital Forensics

Many jurisdictions suffer from lengthy evidence processing backlogs in digital forensics investigations. This has negative consequences for the timely incorporation of digital evidence into criminal investigations, while also affecting the timelines required to bring a case to court. Modern technological advances, in particular the move towards cloud computing, have great potential in expediting the automated processing of digital evidence, thus reducing the manual workload for investigators. It also promises to provide a platform upon which more sophisticated automated techniques may be employed to improve the process further. This paper identifies some research strains from the areas of Information Retrieval and Information Extraction that have the potential to greatly help with the efficiency and effectiveness of digital forensics investigations.
