In contrast to traditional file systems designed for hard disks, the file systems used within smartphones and embedded devices have not been fully analyzed from a forensic perspective. Many modern smartphones make use of the NAND flash file system YAFFS2. In this paper we provide an overview of the file system YAFFS2 from the viewpoint of digital forensics. We show how garbage collection and we...

This paper uses the theory of abstraction layers to describe the purpose and goals of digital forensic analysis tools. Using abstraction layers, we identify where tools can introduce errors and provide requirements that the tools must follow. Categories of forensic analysis types are also defined based on the abstraction layers. Abstraction layers are not a new concept, but their usage in digit...

In the past decade there has been a significant increase in the popularity of synthetic cathinones in the illegal drug market. They have been easily available from Internet-based vendors as well as at "head shops" and "smart shops". The recent prominence of synthetic cathinones can be attributed to their stimulatory properties similar to those of amphetamines. This paper provides a review on th...

Critics, unimpressed by the rigor of the forensic digital examination process, have taken the position that forensic digital analysis is, more rightly, simply little more than ad hoc data collection and analysis. The reality is that forensic digital analysis as a whole, in its relative infancy, is the unwilling victim of the rapid advancement of computer technology. Struggling to keep pace with...

During the past decade, technological advances in mobile phones and the development of smart phones have led to increased use and dependence on the mobile phone. The explosion of its use has led to problems such as fraud, criminal use and identity theft, which have led to the need for mobile phone forensic analysis. In this regard, the authors discuss mobile phone forensic analysis, what it mea...

In this paper, we will show how any speaker recognition system can be adapted to provide its results according to the bayesian approach for evidence analysis and forensic reporting. This approach, firmly established in other forensic areas as fingerprint, DNA or fiber analysis, suits the needs of both the court and the forensic scientist. We will show the inadequacy of the classical approach to...
