Spatial data, also known as geospatial data or geographic information, identifies the geographic location of natural and constructed features and boundaries on Earth, and has become increasingly important in various administrative practices. In order to facilitate access, use, and sharing of spatial data among organizations, information is brought together in clustered initiatives known as Spatial Data Infrastructures (SDIs). In Spatial Data Infrastructures at Work, Ezra Dessers introduces spatial enablement as a key concept to describe the realisation of SDI objectives in the...

Block ciphers encrypt blocks of plaintext, messages, into blocks of ciphertext under the action of a secret key, and the process of encryption is reversed by decryption which uses the same user-supplied key. Block ciphers are fundamental to modern cryptography, in fact they are the most widely used cryptographic primitive - useful in their own right, and in the construction of other cryptographic mechanisms.

In this book the authors provide a technically detailed, yet readable, account of the state of the art of block cipher analysis, design, and deployment. The authors first...

Exploring a vast array of topics related to computation, Computing: A Historical and Technical Perspective covers the historical and technical foundation of ancient and modern-day computing. The book starts with the earliest references to counting by humans, introduces various number systems, and discusses mathematics in early civilizations. It guides readers all the way through the latest advances in computer science, such as the design and analysis of computer algorithms.

Through historical accounts, brief technical explanations, and examples, the book...

In the digital world, the need to protect communications increases every day. While traditional digital encryption methods are useful, there are many other options for hiding your information. Information Hiding in Speech Signals for Secure Communication provides a number of methods to hide secret speech information using a variety of digital speech coding standards. Professor Zhijun Wu has conducted years of research in the field of speech information hiding, and brings his state-of-the-art techniques to readers of this book, including a mathematical model for information hiding,...

Information is everywhere, and defines everything in today's society. Moreover, information is a key concept in a wide range of academic disciplines, from quantum physics to public policy. However, these disciplines all interpret the concept in quite different ways. This book looks at information in several different academic disciplines - cybernetics, ICT, communications theory, semiotics, information systems, library science, linguistics, quantum physics and public policy.

Perspectives on Information brings clarity and coherence to different perspectives through promoting information...

This book focuses mainly on the recent developments of all types of theoretical, mathematical, and computational conceptions, as well as modelling and simulation of specific research themes covering all scientific and technical disciplines from chemistry, physics, and engineering to biology and medicine. The book contains timely reviews and research covering fundamental and applied research aspects in all disciplines of natural sciences, including their historical representations and philosophical perspectives.

The book discusses the fact that the largest and smallest values of the...

Originally developed by Claude Shannon in the 1940s, the theory of information laid the foundations for the digital revolution, and is now an essential tool in deep space communication, genetics, linguistics, data compression, and brain sciences. In this richly illustrated book, accessible examples are used to show how information theory can be understood in terms of everyday games like '20 Questions', and the simple MatLab programs provided give hands-on experience of information theory in action. Written in a tutorial style, with a comprehensive glossary, this text represents an ideal...
