Images, Issues, and Attacks explores important differences between incumbents and challengers in the uses of televised advertising in modern presidential elections. Elections since 1956 can be divided into three categories: elections with strong incumbents, the incumbent wins; elections with weak incumbents, the incumbent loses; and elections with surrogate incumbents, the vice president runs. Incumbent and challenger advertising emphasizes personal imagery, links the imagery to specific issues, and attacks rivals for opposing those images and issues. The first part of the book describes how incumbents and challengers used these themes in the elections from 1980 to 2000. The second part applies those findings to the 2004 election and shows how George W. Bush presented himself as a strong incumbent and how he and his challengers varied their mix of images, issues, and attacks over different periods of the election campaign.

This book defines the nature and scope of insider problems as viewed by the financial industry. This edited volume is based on the first workshop on Insider Attack and Cyber Security, IACS 2007. The workshop was a joint effort from the Information Security Departments of Columbia University and Dartmouth College. The book sets an agenda for an ongoing research initiative to solve one of the most vexing problems encountered in security, and a range of topics from critical IT infrastructure to insider threats. In some ways, the insider problem is the ultimate security problem.

Image Bite Politics is the first book to systematically assess the visual presentation of presidential candidates in network news coverage of elections and to connect these visual images with shifts in public opinion. Presenting the results of a comprehensive visual analysis of general election news from 1992-2004, encompassing four presidential campaigns, the authors highlight the remarkably potent influence of television images when it comes to evaluating leaders. The book draws from a variety of disciplines, including political science, behavioral biology, cognitive neuroscience, and media studies, to investigate the visual framing of elections in an incisive, fresh, and interdisciplinary fashion. Moreover, the book presents findings that are counterintuitive and challenge widely held assumptions--yet are supported by systematic data. For example, Republicans receive consistently more favorable visual treatment than Democrats, countering the conventional wisdom of a "liberal media bias"; and image bites are more prevalent, and in some elections more potent, in shaping voter opinions of candidates than sound bites. Finally, the authors provide a foundation for promoting visual literacy among news audiences and bring the importance of visual analysis to the forefront of research.

Photographic imagery has come a long way from the pinhole cameras of the nineteenth century. Digital imagery, and its applications, develops in tandem with contemporary society’s sophisticated literacy of this subtle medium. This book examines the ways in which digital images have become ever more ubiquitous as legal and medical evidence, just as they have become our primary source of news and have replaced paper-based financial documentation. Crucially, the contributions also analyze the very profound problems which have arisen alongside the digital image, issues of veracity and progeny that demand systematic and detailed response: It looks real, but is it? What camera captured it? Has it been doctored or subtly altered? Attempting to provide answers to these slippery issues, the book covers how digital images are created, processed and stored before moving on to set out the latest techniques for forensically examining images, and finally addressing practical issues such as courtroom admissibility. In an environment where even novice users can alter digital media, this authoritative publication will do much so stabilize public trust in these real, yet vastly flexible, images of the world around us.

This book constitutes the thoroughly refereed post-conference proceedings of the 7th International Workshop on Digital Watermarking, IWDW 2008, held in Busan, Korea, in November 2008. The 36 regular papers included in the volume were carefully reviewed and selected from 62 submissions. Areas of interest to the conference are mathematical modeling of embedding and detection; information theoretic, stochastic aspects of data hiding; security issues, including attacks and counter-attacks; combination of data hiding and cryptography; optimum watermark detection and reliable recovery; estimation of watermark capacity; channel coding techniques for watermarking; large-scale experimental tests and benchmarking; new statistical and perceptual models of content; reversible data hiding; data hiding in special media; data hiding and authentication; steganography and steganalysis; data forensics; copyright protection, DRM, and forensic watermarking; and visual cryptography.

This book presents medical image watermarking techniques and algorithms for telemedicine and other emerging applications. This book emphasizes on medical image watermarking to ensure the authenticity of transmitted medical information. It begins with an introduction of digital watermarking, important characteristics, novel applications, different watermarking attacks and standard benchmark tools. This book also covers spatial and transform domain medical image watermarking techniques and their merits and limitations. The authors have developed improved/novel watermarking techniques for telemedicine applications that offer higher robustness, better perceptual quality and increased embedding capacity and secure watermark. The suggested methods may find potential applications in the prevention of patient identity theft and health data management issues which is a growing concern in telemedicine applications. This book provides a sound platform for understanding the medical image watermarking paradigm for researchers in the field and advanced-level students. Industry professionals working in this field, as well as other emerging applications demanding robust and secure watermarking will find this book useful as a reference.
