Introduction to Information Theory and Data Compression, Second Edition

An effective blend of carefully explained theory and practical applications, this text imparts the fundamentals of both information theory and data compression. Although the two topics are related, this unique text allows either topic to be presented independently, and it was specifically designed so that the data compression section requires no prior knowledge of information theory. The treatment of information theory, while theoretical and abstract, is quite elementary, making this text less daunting than many others. After presenting the fundamental definitions and results of the theory, the authors then apply the theory to memoryless, discrete channels with zeroth-order, one-state sources. The chapters on data compression acquaint students with a myriad of lossless compression methods and then introduce two lossy compression methods. Students emerge from this study competent in a wide range of techniques. The authors' presentation is highly practical but includes some important proofs, either in the text or in the exercises, so instructors can, if they choose, place more emphasis on the mathematics. Introduction to Information Theory and Data Compression, Second Edition is ideally suited for an upper-level or graduate course for students in mathematics, engineering, and computer science. Features: Expanded discussion of the historical and theoretical basis of information theory that builds a firm, intuitive grasp of the subject Reorganization of theoretical results along with new exercises, ranging from the routine to the more difficult, that reinforce students' ability to apply the definitions and results in specific situations. Simplified treatment of the algorithm(s) of Gallager and Knuth Discussion of the information rate of a code and the trade-off between error correction and information rate Treatment of probabilistic finite state source automata, including basic results, examples, references, and exercises Octave and MATLAB image compression codes included in an appendix for use with the exercises and projects involving transform methods Supplementary materials, including software, available for download from the authors' Web site at www.dms.auburn.edu/compression

Information theory leaped fully clothed from the forehead of Claude Shannon in
1948 [63]. The foundation of the theory is a quantification of information, a
quantification that a few researchers had been floundering toward for 20 or 30
years ...

A Multidisciplinary Introduction to Information Security

With most services and products now being offered through digital communications, new challenges have emerged for information security specialists. A Multidisciplinary Introduction to Information Security presents a range of topics on the security, privacy, and safety of information and communication technology. It brings together methods in pure mathematics, computer and telecommunication sciences, and social sciences. The book begins with the cryptographic algorithms of the Advanced Encryption Standard (AES) and Rivest, Shamir, and Adleman (RSA). It explains the mathematical reasoning behind public key cryptography and the properties of a cryptographic hash function before presenting the principles and examples of quantum cryptography. The text also describes the use of cryptographic primitives in the communication process, explains how a public key infrastructure can mitigate the problem of crypto-key distribution, and discusses the security problems of wireless network access. After examining past and present protection mechanisms in the global mobile telecommunication system, the book proposes a software engineering practice that prevents attacks and misuse of software. It then presents an evaluation method for ensuring security requirements of products and systems, covers methods and tools of digital forensics and computational forensics, and describes risk assessment as part of the larger activity of risk management. The final chapter focuses on information security from an organizational and people point of view. As our ways of communicating and doing business continue to shift, information security professionals must find answers to evolving issues. Offering a starting point for more advanced work in the field, this volume addresses various security and privacy problems and solutions related to the latest information and communication technology.

An Introduction to Information Processing

An Introduction to Information Processing provides an informal introduction to the computer field. This book introduces computer hardware, which is the actual computing equipment. Organized into three parts encompassing 12 chapters, this book begins with an overview of the evolution of personal computing and includes detailed case studies on two of the most essential personal computers for the 1980s, namely, the IBM Personal Computer and Apple's Macintosh. This text then traces the evolution of modern computing systems from the earliest mechanical calculating devices to microchips. Other chapters consider the components and operation of typical data communications systems. This book discusses as well the various types of communications networks and communications via space satellites. The final chapter deals with software or computer programs, the sets of instructions that programmers write to inform the computer how to solve particular problems. This book is a valuable resource for computer specialists, mathematicians, and computer programmers.

How do they work? How do they process, store, and transmit information? Is the
operation of computers so complex that only electronic geniuses can understand
them, or are they simple enough for most of us to appreciate and un— derstand?

Introduction to Information Retrieval

Class-tested and coherent, this textbook teaches classical and web information retrieval, including web search and the related areas of text classification and text clustering from basic concepts. It gives an up-to-date treatment of all aspects of the design and implementation of systems for gathering, indexing, and searching documents; methods for evaluating systems; and an introduction to the use of machine learning methods on text collections. All the important ideas are explained using examples and figures, making it perfect for introductory courses in information retrieval for advanced undergraduates and graduate students in computer science. Based on feedback from extensive classroom experience, the book has been carefully structured in order to make teaching more natural and effective. Slides and additional exercises (with solutions for lecturers) are also available through the book's supporting website to help course instructors prepare their lectures.
