‘Investigating crime’ explains how the police investigate criminal activity, setting out some of the principles and procedures involved and how forensic science provides them with answers. Radical changes in English law and forensic science practices resulted in the introduction of formal quality assurance systems to standardize laboratory practices and the Police and Criminal Evidence Act (1984), which specifies how police deal with accused persons, go about their investigations, and are accountable for their actions. The ‘trace, interview, eliminate’ (TIE) method of systematic elimination of individuals from an investigation is described, as well as the role of digital forensics to extract and interpret data from a wide range of devices.

The study and practice of forensic science comprises many distinct areas that range from behavioral to biological to physical and to digital matters, and in each area forensic science is utilized to obtain evidence that will be admissible within the legal framework. This article focuses on inconsistencies within the accepted methodology of digital forensics when comparing the current best practices of mobile digital devices and traditional computer devices. Here the authors raise the awareness of this disconnect in methodology, and they posit that some specific tasks within the traditional best practices of digital forensic science are artifacts of ritual rather than based on scientific requirements.

Tools And Techniques

Digital Forensics is that special branch of forensic science that deals with electronic evidence. Evidence that is electronic in nature could be in several states. When the evidence in contention is a source code with its origin and authorship in question, such evidence comes under the sub-branch of Source Code or Software Forensics. This field has been found to be up and coming as frequent cases pertaining to IPR are being reported in India off late. This paper is a review of this discipline and talks about various tools and techniques that may be employed to process a case in this sub-branch. It discusses the various practical problems that are faced by an investigator in conducting such investigations along with the various shortcomings of the existent techniques. A few relevant and recent case studies along with their various considerations have also been discussed in this work.

The article focuses on the present state of digital forensics and its potential when investigating different types of crimes with a “digital” element. It also presents a brief historical overview of the development of digital forensics as an independent type of forensic examination, its theoretical framework.The paper presents a summary of the practice of the Laboratory of Digital Forensics of the Russian Federal Centre of Forensic Science of the Russian Ministry of Justice over 2017–2019. In the course of the summary, the author analyses typical questions to experts, the percentage of cases’ categories, the most common objects of the expertise, and experts’ opinions, their form, and completeness. Following the summary’s results, the most frequent investigators’ requests for this kind of examination have been highlighted. Also, typical errors at appointing the expertise have been revealed.The author presents a prognosis for the further development of digital forensics and proposes strategies and measures to minimize the errors at the appointment of the examinations and unsustainable expenditure of resources in appointment and conduct of this type of research.

Science provides the basis for truth claims in forensics. Very little research has been done to explore the scientific basis of digital forensics. The work that has been done vary widely in what they propose; in most cases it is unclear how the philosophical remarks about such forensic science apply to digital forensics practice, or that the practical suggestions are a sufficient basis to claim that practice based on them is scientific. This chapter provides an initial exploration of the potential of decision problems from the field of algorithmics to form this scientific basis. There is no doubt that decision problems operate in the scientific domain and decision problems look similar to hypotheses to be of immediate practical use. The chapter suggests that, if decision problems are used in this manner, it is clear that current digital forensics have only scratched the surface of what is possible. Probabilistic complexity classes, for example, offer interesting possibilities for performing complex tests in relatively short times, with known error rates. Using decision problems as a demarcation criterion makes it possible to distinguish between digital forensic science (or simply digital forensics) and digital forensic craft, which should be called digital investigative technique or some other suitable term that does not imply that its use leads to scientific truths.
