The Smartphone
A technology reporter's behind-the-scenes history of the device that has taken over our lives. How have smartphones shaped the way we socialize and interact? Who tracks our actions, our preferences, our movements as recorded by our smartphones? These are just some of the questions that Elizabeth Woyke, a journalist who has covered the industry for Bloomberg Businessweek, Forbes, and MIT Technology Review, addresses in this book. Including photos and an in-depth look at the early decades of mobile communication, The Smartphone offers not only a step-by-step account of how smartphones are designed and manufactured but also a bold exploration of the darker side of this massive industry, including the exploitation of labor, the disposal of electronic waste, and the underground networks that hack and smuggle smartphones. Featuring interviews with key figures in the development of the smartphone and expert assessments of the industry's main players—Apple, Google, Microsoft, and Samsung— The Smartphone is the perfect introduction to this most personal of gadgets. Your smartphone will never look the same again. "The author does a good job explaining the relationships among the makers, carriers and developers, and she delivers an engrossing chapter on design trends." — Kirkus Reviews
Selfie Biometrics
This book highlights the field of selfie biometrics, providing a clear overview and presenting recent advances and challenges. It also discusses numerous selfie authentication techniques on mobile devices. Biometric authentication using mobile devices is becoming a convenient and important means of verifying identity for secured access and services such as telebanking and electronic transactions. In this context, face and ocular biometrics in the visible spectrum has gained increased attention from the research community. However, device mobility and operation in uncontrolled environments mean that facial and ocular images captured with mobile devices exhibit substantial degradation as a result of adverse lighting conditions, specular reflections and motion and defocus blur. In addition, low spatial resolution and the small sensor of front-facing mobile cameras further degrade the sample quality, reducing the recognition accuracy of face and ocular recognition technology when integrated into smartphones. Presenting the state of the art in mobile biometric research and technology, and offering an overview of the potential problems in real-time integration of biometrics in mobile devices, this book is a valuable resource for final-year undergraduate students, postgraduate students, engineers, researchers and academics in various fields of computer engineering.
