Digital forensics is the investigation and recovery of data from digital hardware. The field has grown in recent years to include support for operating systems such as Windows, Linux and Mac OS X. However, little to no support has been provided for less well known systems such as the FreeBSD operating system. The project presented in this paper focuses on creating the foundational support for F...

Cloud computing is arguably one of the most significant advances in information technology (IT) services today. Several cloud service providers (CSPs) have offered services that have produced various transformative changes in computing activities and presented numerous promising technological and economic opportunities. However, many cloud customers remain reluctant to move their IT needs to th...

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 expeditin...

Abstract Steganography is the art and science of writing hidden messages in such a way that no one apart from the intended recipient knows of the existence of the message. In today’s world, it is widely used in order to secure the information. Since digital forensics aims to detect, recover and examine the digital evidence and steganography is a method for hiding digital evidence, detecting the...

Forensic investigative procedures are used in the case of an intrusion into a networked computer system to detect the scope or nature of the attack. In many cases, the forensic procedures employed are constructed in an informal manner that can impede the effectiveness or integrity of the investigation. We propose a formal model for analyzing and constructing forensic procedures, showing the adv...

A digitally altered photograph, often leaving no visual clues of having been tampered with, can be indistinguishable from an authentic photograph. As a result, photographs no longer hold the unique stature as a definitive recording of events. We describe several statistical techniques for detecting traces of digital tampering in the absence of any digital watermark or signature. In particular, ...
