With rapid progress in Internet and digital imaging technology, there are more and more ways to easily create, publish, and distribute images. Considered the first book to focus on the relationship between digital imaging and privacy protection, Visual Cryptography and Secret Image Sharing is a complete introduction to novel security methods and sharing-control mechanisms used to protect against unauthorized data access and secure dissemination of sensitive information. Image data protection and image-based authentication techniques offer efficient solutions for controlling how private data and images are made available only to select people. Essential to the design of systems used to manage images that contain sensitive data—such as medical records, financial transactions, and electronic voting systems—the methods presented in this book are useful to counter traditional encryption techniques, which do not scale well and are less efficient when applied directly to image files. An exploration of the most prominent topics in digital imaging security, this book discusses: Potential for sharing multiple secrets Visual cryptography schemes—based either on the probabilistic reconstruction of the secret image, or on different logical operations for combining shared images Inclusion of pictures in the distributed shares Contrast enhancement techniques Color-image visual cryptography Cheating prevention Alignment problems for image shares Steganography and authentication In the continually evolving world of secure image sharing, a growing number of people are becoming involved as new applications and business models are being developed all the time. This contributed volume gives academicians, researchers, and professionals the insight of well-known experts on key concepts, issues, trends, and technologies in this emerging field.

This book constitutes the refereed proceedings of the 12th International Conference on Information Systems Security, ICISS 2016, held in Jaipur, India, in December 2016. The 24 revised full papers and 8 short papers presented together with 4 invited papers were carefully reviewed and selected from 196 submissions. The papers address the following topics: attacks and mitigation; authentication; authorization and information flow control; crypto systems and protocols; network security and intrusion detection; privacy; software security; and wireless, mobile and IoT security.

iCloud does a lot of amazing things: It keeps your mail, contacts, calendars, reminders, and notes in sync. It instantly (almost magically) copies that photo you took of your cousin on your iPhone to your Mac, iPad mini, and laptop. It lets you work with your Macs from afar. It helps you find stranded and wayward devices, and lets you know when your friends are nearby. And it does it all for free. iCloud encompasses so very many different features and fun bits that it's surprising to realize just how much you can do with a free account. Let Macworld's editors help you get the most out of it. This book collects all the material we've written in the last year on Apple's sync service, and we hope it will help you get to know iCloud and learn how best to use it in your life. This book focuses on OS X 10.8 (Mountain Lion), Windows 8, iOS 6, and iTunes 11 - but we still have some helpful hints for those users with older operating systems. We hope that you enjoy our Starter Guide, but, even more important, that you enjoy iCloud and find ways to incorporate it into your daily routine. If you want to learn more about your other iOS devices, make sure to check out our available Superguides including our iPhone 5 Superguide, iPad Mini Starter Guide, iPad Starter Guide, Fourth Edition (for Retina iPads; Apple's latest iPad, or third generation iPad users running iOS 6), iPhone 5 Starter Guide, iOS 6 Upgrade Guide, and Master iPhone Photography. Looking for Mac and OS X books? We also sell our Total Mountain Lion Superguide, Mac Basics, Mountain Lion, and Mac Gems, Mountain Lion edition.

The book is a collection of high-quality peer-reviewed research papers presented in the first International Conference on Signal, Networks, Computing, and Systems (ICSNCS 2016) held at Jawaharlal Nehru University, New Delhi, India during February 25–27, 2016. The book is organized in to two volumes and primarily focuses on theory and applications in the broad areas of communication technology, computer science and information security. The book aims to bring together the latest scientific research works of academic scientists, professors, research scholars and students in the areas of signal, networks, computing and systems detailing the practical challenges encountered and the solutions adopted.

The Encyclopedia of Image Processing presents a vast collection of well-written articles covering image processing fundamentals (e.g. color theory, fuzzy sets, cryptography) and applications (e.g. geographic information systems, traffic analysis, forgery detection). Image processing advances have enabled many applications in healthcare, avionics, robotics, natural resource discovery, and defense, which makes this text a key asset for both academic and industrial libraries and applied scientists and engineers working in any field that utilizes image processing. Written by experts from both academia and industry, it is structured using the ACM Computing Classification System (CCS) first published in 1988, but most recently updated in 2012.
