Part 1 Multimedia Evidence Handling includes a discussion on the terminology, real-world requirements, standards, legal aspects and technical challenges regarding multimedia evidence which concern forensics examiners and practitioners in law enforcement and digital forensics/e-discovery industry. It will highlight key differences between computer forensics and multimedia forensics, and the new technical challenges raised from such differences. Part 2 Digital Evidence Extraction bridges digital forensics and multimedia forensics by focusing on extraction of two classes of evidence: 1) non-multimedia evidence that can be extracted from multimedia data via a multimedia processing and analysis process, 2) multimedia evidence that are extracted or enhanced via non-multimedia forensic approaches (e.g. by using traditional computer forensic techniques and tools). Part 3 Multimedia Device and Source Forensics focuses on two main topics: digital forensics of multimedia devices and multimedia source identification. The first topic covers available techniques and tools of analysing multimedia devices to recover different types of evidence, and the second topic is about determining the source of a multimedia artefact (a digital or printed multimedia document). Multimedia devices covered include digital cameras/camcorders, audio recorders and players, scanners, printers. Part 4 Multimedia Content Forensics focuses on forensic analysis and identification of multimedia data which is a core area in the multimedia forensic field. Chapters in this part are about pure digital data, but many techniques are based on physical mechanisms that are involved in the generation of the digital data. Some techniques are also based on multimedia device/source identification from the third part, e.g. image forgery may be detected by exposing clues about mismatch of detected sources of different regions of the same image.Vom Verlag:
Digital forensics and multimedia forensics are rapidly growing disciplines whereby electronic information is extracted and interpreted for use in a court of law. These two fields are finding increasing importance in law enforcement and the investigation of cybercrime as the ubiquity of personal computing and the internet becomes ever-more apparent. Digital forensics involves investigating computer systems and digital artefacts in general, while multimedia forensics is a sub-topic of digital forensics focusing on evidence extracted from both normal computer systems and special multimedia devices, such as digital cameras.
This book focuses on the interface between digital forensics and multimedia forensics, bringing two closely related fields of forensic expertise together to identify and understand the current state-of-the-art in digital forensic investigation. Both fields are expertly attended to by contributions from researchers and forensic practitioners specializing in diverse topics such as forensic authentication, forensic triage, forensic photogrammetry, biometric forensics, multimedia device identification, and image forgery detection among many others. Key features: * Brings digital and multimedia forensics together with contributions from academia, law enforcement, and the digital forensics industry for extensive coverage of all the major aspects of digital forensics of multimedia data and devices * Provides comprehensive and authoritative coverage of digital forensics of multimedia data and devices * Offers not only explanations of techniques but also real-world and simulated case studies to illustrate how digital and multimedia forensics techniques work * Includes a companion website hosting continually updated supplementary materials ranging from extended and updated coverage of standards to best practice guides, test datasets and more case studies
