Privacy and Copyright protection is a very important issue in our digital society, where a very large amount of multimedia data are generated and distributed daily using different kinds of consumer electronic devices and very popular communication channels, such as the Web and social networks. This book introduces state-of-the-art technology on data hiding and copyright protection of digital images, and offers a solid basis for future study and research. Steganographic technique overcomes the traditional cryptographic approach, providing new solutions for secure data transmission without raising users' malicious intention. In steganography, some secret information can be inserted into the original data in imperceptible and efficient ways to avoid distortion of the image, and enhance the embedding capacity, respectively. Digital watermarking also adopts data hiding techniques for copyright protection and tampering verification of multimedia data. In watermarking, an illegitimate copy can be recognised by testing the presence of a valid watermark and a dispute on the ownership of the image resolved. Different kinds of steganographic and watermarking techniques, providing different features and diverse characteristics, have been presented in this book. This book provides a reference for theoretical problems as well as practical solutions and applications for steganography and watermarking techniques. In particular, both the academic community (graduate student, post-doc and faculty) in Electrical Engineering, Computer Science, and Applied Mathematics; and the industrial community (engineers, engineering managers, programmers, research lab staff and managers, security managers) will find this book interesting.

QUANTUM BLOCKCHAIN While addressing the security challenges and threats in blockchain, this book is also an introduction to quantum cryptography for engineering researchers and students in the realm of information security. Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. By utilizing unique quantum features of nature, quantum cryptography methods offer everlasting security. The applicability of quantum cryptography is explored in this book. It describes the state-of-the-art of quantum blockchain techniques and sketches how they can be implemented in standard communication infrastructure. Highlighting a wide range of topics such as quantum cryptography, quantum blockchain, post-quantum blockchain, and quantum blockchain in Industry 4.0, this book also provides the future research directions of quantum blockchain in terms of quantum resilience, data management, privacy issues, sustainability, scalability, and quantum blockchain interoperability. Above all, it explains the mathematical ideas that underpin the methods of post-quantum cryptography security. Readers will find in this book a comprehensiveness of the subject including: The key principles of quantum computation that solve the factoring issue. A discussion of a variety of potential post-quantum public-key encryption and digital signature techniques. Explanations of quantum blockchain in cybersecurity, healthcare, and Industry 4.0. Audience The book is for security analysts, data scientists, vulnerability analysts, professionals, academicians, researchers, industrialists, and students working in the fields of (quantum) blockchain, cybersecurity, cryptography, and artificial intelligence with regard to smart cities and Internet of Things.

Even before the terrorist attacks of September 2001, concerns had been rising among security experts about the vulnerabilities to attack of computer systems and associated infrastructure. Yet, despite increasing attention from federal and state governments and international organisations, the defence against attacks on these systems has appeared to be generally fragmented and varying widely in effectiveness. Concerns have grown that what is needed is a national cybersecurity framework -- a co-ordinated, coherent set of public- and private-sector efforts required to ensure an acceptable level of cybersecurity for the nation. As commonly used, cybersecurity refers to three things: measures to protect information technology; the information it contains, processes, and transmits, and associated physical and virtual elements (which together comprise cyberspace); the degree of protection resulting from application of those measures; and the associated field of professional endeavour. Virtually any element of cyberspace can be at risk, and the degree of interconnection of those elements can make it difficult to determine the extent of the cybersecurity framework that is needed. Identifying the major weaknesses in U.S. cybersecurity is an area of some controversy. However, some components appear to be sources of potentially significant risk because either major vulnerabilities have been identified or substantial impacts could result from a successful attack -- in particular, components that play critical roles in elements of critical infrastructure, widely used commercial software, organisational governance, and the level of public knowledge and perception about cybersecurity. There are several options for broadly addressing weaknesses in cybersecurity. They include adopting standards and certification, promulgating best practices and guidelines, using benchmarks and checklists, use of auditing, improving training and education, building security into enterprise architecture, using risk management, and using metrics. These different approaches all have different strengths and weaknesses with respect to how they might contribute to the development of a national framework for cybersecurity. None of them are likely to be widely adopted in the absence of sufficient economic incentives for cybersecurity.

The term 'spyware' is not well defined. Generally it is used to refer to any software that is downloaded onto a person's computer without their knowledge. Spyware may collect information about a computer user's activities and transmit that information to someone else. It may change computer settings, or cause 'pop-up' advertisements to appear (in that context, it is called 'adware'). Spyware may redirect a Web browser to a site different from what the user intended to visit, or change the user's home page. A type of spyware called 'keylogging' software records individual keystrokes, even if the author modifies or deletes what was written, or if the characters do not appear on the monitor. Thus, passwords, credit card numbers, and other personally identifiable information may be captured and relayed to unauthorised recipients. Some of these software programs have legitimate applications the computer user wants. They obtain the moniker 'spyware' when they are installed surreptitiously, or perform additional functions of which the user is unaware. Users typically do not realise that spyware is on their computer. They may have unknowingly downloaded it from the Internet by clicking within a website, or it might have been included in an attachment to an electronic mail message (e-mail) or embedded in other software. According to a survey and tests conducted by America Online and the National Cyber Security Alliance, 80% of computers in the test group were infected by spyware or adware, and 89% of the users of those computers were unaware of it. The Federal Trade Commission (FTC) issued a consumer alert on spyware in October 2004. It provided a list of warning signs that might indicate that a computer is infected with spyware, and advice on what to do if it is. This new book helps shed light on this insidious nightmare created by members of the human race to wreck havoc on the remainder.

Since the collapse of the Soviet Union, the United States has faced the challenge of reorienting its foreign policy to address post-Cold War conditions. In this new edition of a groundbreaking work -- one of the first to bring critical theory into dialogue with more traditional approaches to international relations -- David Campbell provides a fundamental reappraisal of American foreign policy, with a new epilogue to address current world affairs and the burgeoning focus on culture and identity in the study of international relations.

Extending recent debates in international relations, Campbell shows how perceptions of danger and difference work to establish the identity of the United States. He demonstrates how foreign policy, far from being an expression of a given society, constitutes state identity through the interpretation of danger posed by others.

Strong Pseudorandompermutations or SPRPs,which were introduced byLuby andRacko? [4], formalize the well established cryptographic notion ofblock ciphers.They provided a construction of SPRP, well known as LRconstruction, which was motivated by the structure of DES[6].The basicbuildingblock is the so called 2n-bit Feistel permutation (or LR round permutation) LR based F K on an n-bitpseudorandomfunction (PRF) F : K n LR (x ,x)=(F (x )?x ,x ),x ,x?{0,1} .

Industrial cyber-physical systems operate simultaneously in the physical and digital worlds of business and are now a cornerstone of the fourth industrial revolution. Increasingly, these systems are becoming the way forward for academics and industrialists alike. The very essence of these systems, however, is often misunderstood or misinterpreted. This book thus sheds light on the problem areas surrounding cyber-physical systems and provides the reader with the key principles for understanding and illustrating them. Presented using a pedagogical approach, with numerous examples of applications, this book is the culmination of more than ten years of study by the Intelligent Manufacturing and Services Systems (IMS2) French research group, part of the MACS (Modeling, Analysis and Control of Dynamic Systems) research group at the CNRS. It is intended both for engineers who are interested in emerging industrial developments and for master's level students wishing to learn about the industrial systems of the future.

'The best book on codebreaking I have read', SIR DERMOT TURING 'Brings back the joy I felt when I first read about these things as a kid', PHIL ZIMMERMANN 'This is at last the single book on codebreaking that you must have. If you are not yet addicted to cryptography, this book will get you addicted. Read, enjoy, and test yourself on history's great still-unbroken messages!' JARED DIAMOND is the Pulitzer Prize-winning author of Guns, Germs, and Steel; Collapse; and other international bestsellers 'This is THE book about codebreaking. Very concise, very inclusive and easy to read', ED SCHEIDT 'Riveting', MIKE GODWIN 'Approachable and compelling', GLEN MIRANKER This practical guide to breaking codes and solving cryptograms by two world experts, Elonka Dunin and Klaus Schmeh, describes the most common encryption techniques along with methods to detect and break them. It fills a gap left by outdated or very basic-level books. This guide also covers many unsolved messages. The Zodiac Killer sent four encrypted messages to the police. One was solved; the other three were not. Beatrix Potter's diary and the Voynich Manuscript were both encrypted - to date, only one of the two has been deciphered. The breaking of the so-called Zimmerman Telegram during the First World War changed the course of history. Several encrypted wartime military messages remain unsolved to this day. Tens of thousands of other encrypted messages, ranging from simple notes created by children to encrypted postcards and diaries in people's attics, are known to exist. Breaking these cryptograms fascinates people all over the world, and often gives people insight into the lives of their ancestors. Geocachers, computer gamers and puzzle fans also require codebreaking skills. This is a book both for the growing number of enthusiasts obsessed with real-world mysteries, and also fans of more challenging puzzle books. Many people are obsessed with trying to solve famous crypto mysteries, including members of the Kryptos community (led by Elonka Dunin) trying to solve a decades-old cryptogram on a sculpture at the centre of CIA Headquarters; readers of the novels of Dan Brown as well as Elonka Dunin's The Mammoth Book of Secret Code Puzzles (UK)/The Mammoth Book of Secret Codes and Cryptograms (US); historians who regularly encounter encrypted documents; perplexed family members who discover an encrypted postcard or diary in an ancestor's effects; law-enforcement agents who are confronted by encrypted messages, which also happens more often than might be supposed; members of the American Cryptogram Association (ACA); geocachers (many caches involve a crypto puzzle); puzzle fans; and computer gamers (many games feature encryption puzzles). The book's focus is very much on breaking pencil-and-paper, or manual, encryption methods. Its focus is also largely on historical encryption. Although manual encryption has lost much of its importance due to computer technology, many people are still interested in deciphering messages of this kind.
