The manner in which results of digital image forensic investigations are presented in the courtroom can be positively or adversely affected by case law, federal rules and legislative acts, availability of discovery materials, tools, and the use of exhibits. Issues pertinent to effective and successful testimony are addressed, along with suggestions for improvement of methods. 1 Computer Forensi...

In the digital forensics discipline, lack of comprehensive research that addresses investigative challenges and opportunities for newer mobile Operating Systems (OSs) such as Android iOS keeps continuing. These two OSs are currently widely operated by millions smartphones used users; therefore, forensic investigators need to be prepared analyze these during an investigation giving consideration...

Recently the need for “digital evidence bags” – a common storage format for digital evidence – has been identified as a key requirement for enabling inter-organisational sharing of digital evidence, and interoperability between forensic analysis tools. Recent work has described an ontology based approach to correlation of event log based evidence, using semantic web technologies for describing ...

Progress in computer forensics research has been limited by the lack of a standardized data setsdcorporadthat are available for research purposes. We explain why corpora are needed to further forensic research, present a taxonomy for describing corpora, and announce the availability of several forensic data sets. a 2009 Digital Forensic Research Workshop.

Noise is an intrinsic specificity of all forms of imaging, and can be found in various forms in all domains of digital imagery. This paper offers an overall review of digital image noise, from its causes and models to the degradations it suffers along the image acquisition pipeline. We show that by the end of the pipeline, the noise may have widely different characteristics compared to the raw ...

We are proposing forensic techniques that are capable of detecting traces of tampering in digital Video without specialized hardware. These techniques operate under The assumption that video contain naturally occurring properties which are disturbed by Tampering, and which can be quantifed, measured, and used to expose video fakes. In this context we are proposing techniques used in copy-paste ...
