1.4 CONCLUSION
Chapter 1 is concerned with presenting the background information for this research
and its the main motivation. A snapshot of the research findings is also captured and
presented in this chapter. The main purpose is to summarise the key research findings
and present them in a concise manner. The structure of this thesis from chapter 1 to 6
has been laid out with a brief introduction.
The rationales behind this research are also explained from both legal and
technological perspectives. The main rationale behind the research is to fill the gaps in
previous studies in the same domain. The findings about the testing environment,
procedures and the performance of the disk imaging tools are also explained briefly.
The structure of this thesis also provides guidance for the readers.
To further explore the gaps in the research field, Section 2.1 offers an overview
of the digital forensic environment, including the review of relevant literature about
the investigative processes and the development of digital forensic tools. Some
previously conducted studies on legal and technical implications of digital forensic
areas are reviewed in Section 2.2. The legal significance of the digital forensic tools
lies in the admissibility of digital evidence. The technical and legal challenges are
