Digital Forensics in Small Devices: RFID Tag Investigation

3.0 INTRODUCTION
Chapter 3 -
Research Methodology
Chapter 2 reviewed the literature relating to a RFID system, the information system
of RFID architecture, the business system (BS), security challenges, and the proposed
RFID BS security risks. This chapter will derive a research methodology and identify
the main research question, sub questions and hypotheses. The specification for data
collection, processing and analysis will also be given.
It is proposed that the RFID security risks identified in Chapter 2 will be
exploited to crack a trial business system in laboratory conditions. The system is to be
stressed by running transaction scenarios. Hence, the whole system (chip, network, &
database) can be searched for sources of digital evidence (stored data). Finally, the
process steps are to be analyzed and written up as a guide for best practice for the
digital forensic investigators.
The research methodology is to be based on descriptive methods for using
case scenarios. In Section 3.1 previous similar studies are reviewed to ground the
method in others published papers. Hence, the methodology chapter is firstly
organized into the review of similar published works (Section 3.1); the research
design, research question and hypotheses (Section 3.2); and the data requirements
such as how data is to be collected, processed, analyzed and presented (Section 3.3).
Then, the limitations and expected outcomes of the research (Section 3.4) will be
followed by the conclusion (Section 3.5).
3.1 REVIEW OF SIMILAR PUBLISHED WORKS
In order to develop the methodology, the reviews of similar works have been
identified and analysed. The analysis of these studies had lead to the methodology for
this research project. The previous similar published works have guided the ways in
