Book excerpt: A concise and accessible guide to techniques for detecting doctored and fake images in photographs and digital media. Stalin, Mao, Hitler, Mussolini, and other dictators routinely doctored photographs so that the images aligned with their messages. They erased people who were there, added people who were not, and manipulated backgrounds. They knew if they changed the visual record, they could change history. Once, altering images required hours in the darkroom; today, it can be done with a keyboard and mouse. Because photographs are so easily faked, fake photos are everywhere—supermarket tabloids, fashion magazines, political ads, and social media. How can we tell if an image is real or false? In this volume in the MIT Press Essential Knowledge series, Hany Farid offers a concise and accessible guide to techniques for detecting doctored and fake images in photographs and digital media. Farid, an expert in photo forensics, has spent two decades developing techniques for authenticating digital images. These techniques model the entire image-creation process in order to find the digital disruption introduced by manipulation of the image. Each section of the book describes a different technique for analyzing an image, beginning with those requiring minimal technical expertise and advancing to those at intermediate and higher levels. There are techniques for, among other things, reverse image searches, metadata analysis, finding image imperfections introduced by JPEG compression, image cloning, tracing pixel patterns, and detecting images that are computer generated. In each section, Farid describes the techniques, explains when they should be applied, and offers examples of image analysis.

Book excerpt: Photographs of contemporary Veles are intertwined with fragments from an archaeological discovery also called 'the Book of Veles' -- a cryptic collection of 40 'ancient' wooden boards discovered in Russia in 1919, written in a proto-Slavic language. It was claimed to be a history of the Slavic people and the god Veles himself--the pre-Christian Slavic god of mischief, chaos and deception

Book excerpt: The first comprehensive and detailed presentation of techniques for authenticating digital images. Photographs have been doctored since photography was invented. Dictators have erased people from photographs and from history. Politicians have manipulated photos for short-term political gain. Altering photographs in the predigital era required time-consuming darkroom work. Today, powerful and low-cost digital technology makes it relatively easy to alter digital images, and the resulting fakes are difficult to detect. The field of photo forensics—pioneered in Hany Farid's lab at Dartmouth College—restores some trust to photography. In this book, Farid describes techniques that can be used to authenticate photos. He provides the intuition and background as well as the mathematical and algorithmic details needed to understand, implement, and utilize a variety of photo forensic techniques. Farid traces the entire imaging pipeline. He begins with the physics and geometry of the interaction of light with the physical world, proceeds through the way light passes through a camera lens, the conversion of light to pixel values in the electronic sensor, the packaging of the pixel values into a digital image file, and the pixel-level artifacts introduced by photo-editing software. Modeling the path of light during image creation reveals physical, geometric, and statistical regularities that are disrupted during the creation of a fake. Various forensic techniques exploit these irregularities to detect traces of tampering. A chapter of case studies examines the authenticity of viral video and famously questionable photographs including “Golden Eagle Snatches Kid” and the Lee Harvey Oswald backyard photo.

Book excerpt: Choosing the right technologies to match student learning outcomes in today's technology-integrated classrooms presents educators and instructional designers with multiple curricula and instructional design challenges including selecting appropriate technologies to match desired student learning outcomes. As students continue to have broad access to information from a variety of web-based platforms, educators and educational professionals are increasingly tasked with ensuring the information used to complete key assignments or tasks is authentic and from a verifiable resource. As such, the era of deep fakes in images, audios, videos, and digital texts is more prevalent than ever as numerous programs using artificial intelligence (AI) can significantly alter original content to fundamentally change the intent of original content. Moreover, students are being bombarded by a plethora of information that is either intentionally or mistakenly false and must be navigated with care. Accordingly, educators and educational professionals are now tasked with employing best practices to not only teach basic digital literacy and citizenship skills but also to recognize how technology-immersed learning environments interact with deep fakes and misinformation while equipping students with the tools necessary to recognize authentic and altered content. Deep Fakes, Fake News, and Misinformation in Online Teaching and Learning Technologies is a critical reference source that addresses rising concerns of students’ ability to navigate the multitude of false and altered information and content that is easily accessible through online platforms. The chapters go into deeper detail about how deep fakes, fake news, and mis- and dis-information have the potential of negatively affecting the fields of teaching and learning and the importance of student access to content-related tasks from legitimate, vetted resources that accurately reflect the desired information the student means to convey. The book seeks to reinforce the importance of digital literacy and digital citizenship among adolescents. This book is essential for teaching faculty, higher education faculty, higher education administrators, educational software developers, security specialists, information specialists, media specialists, librarians, educational researchers, and students looking for information on how deep fakes and fake news are being navigated within the context of online teaching and educational technologies.

Book excerpt: The man who is “the embodiment of the Mythbusters, Sherlock Holmes, and Richard Feynman” weeds out the treasures from the shams in artifact investigations (Michael Shermer, founding publisher of Skeptic magazine). Detailing how the pros determine whether an Abraham Lincoln signature is forged or if a photograph of Emily Dickinson is genuine, Nickell, a leader in forgery detection and forensic investigation, provides the essential tools necessary to identify counterfeits. In this general introduction to the principles of authentication, Nickell provides readers with step-by-step explanations of the science used to detect falsified documents, photographs, and other objects, illustrating methods used on hit shows such as Antiques Roadshow and History Detectives. Including fascinating cases drawn from Nickell’s illustrious career, Real or Fake combines historical and scientific investigations to reveal reproductions and genuine objects. Nickell explains the warning signs of forgery, such as patching and unnatural pen lifts; chronicles the evolution of writing instruments, inks, and papers; shows readers how to date photographs, papers, and other materials; and traces the development of photographic processes since the mid-nineteenth century. Lavishly illustrated with examples of replicas and authentic objects inspected by Nickell, Real or Fake includes case studies of alleged artifacts including Jack the Ripper’s diary, a draft of the Gettysburg Address, notes by Charles Dickens, Jefferson Davis’s musket, and debris from the Titanic. “An expert on antique ink and paper, and the forensic analysis of historic documents.” —The New Yorker “Nickell advocates a multifaceted approach that looks at provenance, content, material composition, and scientific analysis.” —Maine Antique Digest

Book excerpt: New perspectives on the misinformation ecosystem that is the production and circulation of fake news. What is fake news? Is it an item on Breitbart, an article in The Onion, an outright falsehood disseminated via Russian bot, or a catchphrase used by a politician to discredit a story he doesn't like? This book examines the real fake news: the constant flow of purposefully crafted, sensational, emotionally charged, misleading or totally fabricated information that mimics the form of mainstream news. Rather than viewing fake news through a single lens, the book maps the various kinds of misinformation through several different disciplinary perspectives, taking into account the overlapping contexts of politics, technology, and journalism. The contributors consider topics including fake news as “disorganized” propaganda; folkloric falsehood in the “Pizzagate” conspiracy; native advertising as counterfeit news; the limitations of regulatory reform and technological solutionism; Reddit's enabling of fake news; the psychological mechanisms by which people make sense of information; and the evolution of fake news in America. A section on media hoaxes and satire features an oral history of and an interview with prankster-activists the Yes Men, famous for parodies that reveal hidden truths. Finally, contributors consider possible solutions to the complex problem of fake news—ways to mitigate its spread, to teach students to find factually accurate information, and to go beyond fact-checking.

Book excerpt: The Threats of Algorithms and A.I. to Civil Rights, Legal Remedies, and American Jurisprudence addresses the many threats to American jurisprudence caused by the growing use of algorithms and artificial intelligence (A.I.). Although algorithms prove valuable to society, that value may also lead to the destruction of the foundations of American jurisprudence by threatening constitutional rights of individuals, creating new liabilities for business managers and board members, disrupting commerce, interfering with long-standing legal remedies, and causing chaos in courtrooms trying to adjudge lawsuits. Alfred R. Cowger, Jr. explains these threats and provides potential solutions for both the general public and legal practitioners. Scholars of legal studies, media studies, and political science will find this book particularly useful.
