Title of dissertation: DIGITAL MULTIMEDIA FORENSICS AND ANTI-FORENSICS Matthew C. Stamm, Doctor of Philosophy, 2012 Dissertation directed by: Professor K. J. Ray Liu Department of Electrical and Computer Engineering As the use of digital multimedia content such as images and video has increased, so has the means and the incentive to create digital forgeries. Presently, powerful editing software...

–Digital forensics tools frequently use to calculate the hash value of digital evidence drive. MD5 and SHA hash function is used in digital forensic tools to calculate and verify that a data set has not been altered, due to the application of various evidence collection and analysis tools and procedures. Additionally, due to the impact on the personal life of the subject of an investigation, ve...

The new cloud computing concept delivers an adaptable service to many users. This is due to the fact that cloud computing offers an economic solution based on pay-per use idea. At the same time, digital forensics is a relatively new discipline born out due to the growing use of computing and digital solution. Digital forensics in cloud computing brings new technical and legal challenges (e.g. t...

Discovering Hidden Evidence C. Hosmer Chet Hosmer WetStone Technologies, Inc., Cortland, New York, USA ABSTRACT Over the past decade, the advancement of a myriad of methods, techniques and technologies to conceal digital evidence and covertly communicate have increased at an alarming rate. In addition, new information suggests that the download of an arsenal of software tools that perform these...

Many digital forensic tools used by investigators were not originally designed for forensic applications. Even in the case of tools created with the forensic process in mind, there is the issue of assuring their reliability and dependability. Given the nature of investigations and the fact that the data collected and analyzed by the tools must be presented as evidence, it is important that digi...

In this paper, researchers provide a preliminary analysis on the forensic implications of cloud computing reference architecture, on the segregation of duties of cloud actors in cloud investigations, forensic artifacts on all layers of cloud system stack, cloud actors interaction scenarios in cloud investigations, and forensic implications of all cloud deployment models. The analysis serves as ...

In this paper we present study about how to analyze the malware on the system for digital investigation and also give the superficial knowledge and comparison about forensic model. This paper proposes a plan for achieving a dramatic improvement in research and operational efficiency through the adoption of systematic approaches for representing forensic data and performing forensic computation....

Ontologies are widely used in different disciplines as a technique for representing and reasoning about domain knowledge. However, despite the widespread ontology-related research activities and applications in different disciplines, the development of ontologies and ontology research activities is still wanting in digital forensics. This paper therefore presents the case for establishing an on...

Digital forensic examiners are tasked with retrieving data from digital storage devices, and frequently these examiners are expected to explain the circumstances that led to the data being in its current state. Through written reports or verbal, expert testimony delivered in court, digital forensic examiners are expected to describe whether data have been altered, and if so, then to what extent...
