Multimedia Forensics


Book Description

This book is open access. Media forensics has never been more relevant to societal life. Not only media content represents an ever-increasing share of the data traveling on the net and the preferred communications means for most users, it has also become integral part of most innovative applications in the digital information ecosystem that serves various sectors of society, from the entertainment, to journalism, to politics. Undoubtedly, the advances in deep learning and computational imaging contributed significantly to this outcome. The underlying technologies that drive this trend, however, also pose a profound challenge in establishing trust in what we see, hear, and read, and make media content the preferred target of malicious attacks. In this new threat landscape powered by innovative imaging technologies and sophisticated tools, based on autoencoders and generative adversarial networks, this book fills an important gap. It presents a comprehensive review of state-of-the-art forensics capabilities that relate to media attribution, integrity and authenticity verification, and counter forensics. Its content is developed to provide practitioners, researchers, photo and video enthusiasts, and students a holistic view of the field.

Handbook of Digital Forensics of Multimedia Data and Devices, Enhanced E-Book


Book Description

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




Multimedia Forensics and Security


Book Description

This book presents recent applications and approaches as well as challenges in digital forensic science. One of the evolving challenges that is covered in the book is the cloud forensic analysis which applies the digital forensic science over the cloud computing paradigm for conducting either live or static investigations within the cloud environment. The book also covers the theme of multimedia forensics and watermarking in the area of information security. That includes highlights on intelligence techniques designed for detecting significant changes in image and video sequences. Moreover, the theme proposes recent robust and computationally efficient digital watermarking techniques. The last part of the book provides several digital forensics related applications, including areas such as evidence acquisition enhancement, evidence evaluation, cryptography, and finally, live investigation through the importance of reconstructing the botnet attack scenario to show the malicious activities and files as evidences to be presented in a court.




MATERIAL WITNESS


Book Description

The evidential role of matter—when media records trace evidence of violence—explored through a series of cases drawn from Kosovo, Japan, Vietnam, and elsewhere. In this book, Susan Schuppli introduces a new operative concept: material witness, an exploration of the evidential role of matter as both registering external events and exposing the practices and procedures that enable matter to bear witness. Organized in the format of a trial, Material Witness moves through a series of cases that provide insight into the ways in which materials become contested agents of dispute around which stake holders gather. These cases include an extraordinary videotape documenting the massacre at Izbica, Kosovo, used as war crimes evidence against Slobodan Milošević; the telephonic transmission of an iconic photograph of a South Vietnamese girl fleeing an accidental napalm attack; radioactive contamination discovered in Canada's coastal waters five years after the accident at Fukushima Daiichi; and the ecological media or “disaster film” produced by the Deep Water Horizon oil spill in the Gulf of Mexico. Each highlights the degree to which a rearrangement of matter exposes the contingency of witnessing, raising questions about what can be known in relationship to that which is seen or sensed, about who or what is able to bestow meaning onto things, and about whose stories will be heeded or dismissed. An artist-researcher, Schuppli offers an analysis that merges her creative sensibility with a forensic imagination rich in technical detail. Her goal is to relink the material world and its affordances with the aesthetic, the juridical, and the political.
