Book Description
Secret sharing schemes form one of the most important topic in Cryptography. These protocols are used in many areas, applied mathematics, computer science, electrical engineering. A secret is divided into several pieces called shares. Each share is given to a user of the system. Each user has no information about the secret, but the secret can be retrieved by certain authorized coalition of users.This book is devoted to such schemes inspired by Coding Theory. The classical schemes of Shamir, Blakley, Massey are recalled. Survey is made of research in Combinatorial Coding Theory they triggered, mostly self-dual codes, and minimal codes. Applications to engineering like image processing, and key management of MANETs are highlighted.

Book Description
The project that captured a nation's imagination. The instructions were simple, but the results were extraordinary. "You are invited to anonymously contribute a secret to a group art project. Your secret can be a regret, fear, betrayal, desire, confession, or childhood humiliation. Reveal anything -- as long as it is true and you have never shared it with anyone before. Be brief. Be legible. Be creative." It all began with an idea Frank Warren had for a community art project. He began handing out postcards to strangers and leaving them in public places -- asking people to write down a secret they had never told anyone and mail it to him, anonymously. The response was overwhelming. The secrets were both provocative and profound, and the cards themselves were works of art -- carefully and creatively constructed by hand. Addictively compelling, the cards reveal our deepest fears, desires, regrets, and obsessions. Frank calls them "graphic haiku," beautiful, elegant, and small in structure but powerfully emotional. As Frank began posting the cards on his website, PostSecret took on a life of its own, becoming much more than a simple art project. It has grown into a global phenomenon, exposing our individual aspirations, fantasies, and frailties -- our common humanity. Every day dozens of postcards still make their way to Frank, with postmarks from around the world, touching on every aspect of human experience. This extraordinary collection brings together the most powerful, personal, and beautifully intimate secrets Frank Warren has received -- and brilliantly illuminates that human emotions can be unique and universal at the same time.

Book Description
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.

Book Description
An educational toolkit for teaching phonics, consisting of a book, posters and musical CD, all of which provides for multiple options and inputs for learning, including: visual-icons, auditory and kinesthetic motor skill manipulations, as well as a variety of dramatic and emotive cuing-systems designed to target the affective learning domain. This "backdoor-approach" to phonemic skill acquisition is based on current neural research on Learning & the Brain--specifically how our brains actually learn best!The Secret Stories® primary purpose is to equip beginning (or struggling, upper grade) readers and writers, as well as their instructors, with the tools necessary to easily and effectively crack the secret reading and writing codes that lie beyond the alphabet, and effectively out of reach for so many learners! It is not a phonics program! Rather, it simply provides the missing pieces learners need to solve the complex reading puzzle--one that some might never solve otherwise! The Secrets(tm) are sure to become one of the most valuable, well-used, and constantly relied-upon teaching tools in your instructional repertoire!

TCC 2005, the 2nd Annual Theory of Cryptography Conference, was held in Cambridge,Massachusetts,onFebruary10–12,2005.Theconferencereceived84 submissions,ofwhichtheprogramcommitteeselected32forpresentation.These proceedings contain the revised versions of the submissions that were presented at the conference. These revisions have not been checked for correctness, and the authors bear full responsibility for the contents of their papers. The conference program also included a panel discussion on the future of theoretical cryptography and its relationship to the real world (whatever that is). It also included the traditional “rump session,” featuring short, informal talks on late-breaking research news. Much as hatters of old faced mercury-induced neurological damage as an occupational hazard, computer scientists will on rare occasion be a?icted with egocentrism, probably due to prolonged CRT exposure. Thus, you must view withpityandnotcontemptmyunalloyedelationathavingmynameonthefront cover of this LNCS volume, and my deep-seated conviction that I fully deserve the fame and riches that will surely come of it. However, having in recent years switched over to an LCD monitor, I would like to acknowledge some of the many who contributed to this conference. First thanks are due to the many researchers from all over the world who submitted their work to this conference. Lacking shrimp and chocolate-covered strawberries, TCC has to work hard to be a good conference. As a community, I think we have.

Book Description
Newbery Medal–winning author Patricia MacLachlan paints a moving portrait of what it means to be a family, the power of love, and the importance of bringing the truth out into the light, in this beautiful and profound story about adoption. Nora and Ben’s younger sister Birdy loves to keep secrets. She surprises her family more than once: She hides a kitten in her room. She writes a beautiful poem. One day Birdy watches her mother spit into a tube, ready to send it off to find out more about herself and where her family came from. Birdy spits into a tube, too, when no one sees her. But when the test results come back, they are a surprise. Birdy is seemingly not related to Nora and Ben’s parents. But if she is adopted, how could that have happened without the children knowing? Nora and Ben must learn when to keep a secret, and who to go to for help—and eventually, how to solve this secret for the entire family.
