This is a book for those interested in understanding how graphics programs work and how present-day computer graphics can generate reallistic-looking curves, surfaces, and solid objects. The book emphasizes the mathematics behind computer graphics and most of the required math is included in an appendix. The main topics covered are: -scan conversion methods; selecting the best pixels for generating lines, circles and other objects -geometric transformations and projections; translations, rotations, moving in 3d, perspective projections -curves and surfaces; construction, wire-frames, rendering, normals -other topics; CRTs, antialiasing, animation, color, perception, polygons, compression. With its numerous illustrative examples and exercises, the book makes a splendid text for a two-semester course in computer graphics for advanced undergraduates or graduate students. It also serves a fine reference for professionals in the computer graphics field.

An essential resource and monograph for all security researchers and practitioners who want to understand and effectively use 'both' information hiding techniques and encryption to protect digital data and have secure communications. All major topics and techniques are presented in an accessible style and suitable for specialists and nonspecialists.

Joseph-Louis Lagrange (1736-1813), one of the greatest mathematicians of the 18th century, made important contributions to the theory of numbers and to analytical and celestial mechanics. His most important work is Mecanique Analytique (1788), the textbook on which all subsequent work in this field is based. A contempo- rary reader is surprised to find no diagrams or figures of any kind in this book on mechanics. This reflects one extreme approach to graphics, namely considering it unimportant or even detracting as a teaching tool and not using it. Today, of course, this approach is unthinkable. Graphics, especially computer graphics, is commonly used in texts, advertisements, and movies to illustrate concepts, to emphasize points being discussed, and to entertain. Our approach to graphics has been completely reversed since the days of La- grange, and it seems that much of this change is due to the use of computers. Computer graphics today is a mature, successful, and growing field. It is used by many people for many purposes and it is enjoyed by even more people. One criterion for the maturity of a field of study is its size. When a certain discipline becomes so big that no one person can keep all of it in their head, we say that that discipline has matured (or has come of age). This is what happened to computer graphics in the last decade or so.

As our society grows ever more reliant on computers, so it also becomes more vulnerable to computer crime. Cyber attacks have been plaguing computer users since the 1980s, and computer security experts are predicting that smart telephones and other mobile devices will also become the targets of cyber security threats in the future.Developed from the author's highly successful Springer text, Foundations of Computer Security, this accessible, broad-ranging, and versatile textbook has been fully updated and enhanced with resources for students, instructors, and even those motivated to self-study on this topic.Topics and features: Examines the physical security of computer hardware, networks, and digital data Introduces the different forms of rogue software (or malware), discusses methods for preventing and defending against them, and thoroughly describes a selection of viruses, worms and Trojans in detail Provides numerous exercises and examples throughout the text, in addition to a Glossary of terms used in the book Investigates the important threats to network security, and explores the timely subjects of authentication, spyware, and identity theft Discusses key issues about privacy and trust in the online world, including children's privacy and safety Includes helpful appendices which discuss the definition, meaning, and history of the term "hacker"; introduce the language of "l33t Speak;" and provide a detailed virus timeline Supplies additional resources at the associated website: http://www.DavidSalomon.name/, including an introduction to cryptography, and answers to the exercisesClearly and engagingly written, this concise textbook is an ideal resource for undergraduate classes on computer security, as well as a solid reference for anyone needing to expand their security knowledge. The book is mostly non-mathematical, and is suitable for anyone familiar with the basic concepts of computers and computations.David Salomon is a professor emeritus of Computer Science at California State University, Northridge. He has authored numerous articles and Springer books, including Handbook of Data Compression, A Concise Introduction to Data Compression, Variable-length Codes for Data Compression, Transformations and Projections in Computer Graphics, Curves and Surfaces for Computer Graphics, Coding for Data and Computer Communications, Data Privacy and Security, and A Guide to Data Compression Methods.

All aspects of computer security-from the firewall for a home PC to the most daunting designs for large distributed systems-are becoming increasingly important worldwide. However, the complexities of securing computing systems can often make the topic too intimidating or onerous for people who are relative novices.Foundations of Computer Security provides a succinct, yet authoritative introduction to the underlying theory, history, vocabulary, and concepts that drive this pivotal area of computer science. With its user-friendly approach and clarity of style, the text conveys-in simple terms-the core principles and developments underlying computer security in its many ramifications in the rapidly evolving computing arena. Following its opening framework laid out in a broad preface and introductory chapter, the book features chapters dedicated to a wide array of security-related subtopics: physical security, viruses and worms, malware and spyware, privacy and trust, and cryptography, to name several. The work is a sort of guidebook for newcomers: It assumes only basic knowledge of computers and refrains from heavy mathematical elements.Topics and Features:¿ Provides a comprehensive, accessible overview of the elements of computer security, conveyed in an easy-to-understand style¿ Covers the main security challenges, and introduces cryptography¿ Reinforces its themes with thorough use of examples, exercises (with answers), historical anecdotes, and case studies¿ Features a supplemental website for auxiliary instructional material¿ Supplies numerous resources, including a helpful glossary, a virus timeline, and an extensive bibliography¿ Instructs readers through a logical andprogressive method, yet flavors treatment of the topic with enjoyable quotes, provocative questions, and other educational tools¿ Presents the "essentials," but offers additional useful background informationThis broad, yet practical textbook/reference is an invaluable instructional tool for undergraduates, graduates, or professionals who know at least the basics about computers but need some exposure to the key elements pertaining to computer security. Its concise approach, complemented by its breadth of security issues covered, will make it an ideal resource for those hoping to learn the foundation topics of this critical subject.David Salomon is a professor emeritus of computer science at California State University, Northridge. He has authored numerous articles, as well as the popular books, Data Compression: The Complete Reference (now in its third edition) and Data Privacy and Security.

This book presents a broad overview of computer graphics (CG), its history, and the hardware tools it employs. examines advanced techniques in CG, including the nature and properties of light and color, graphics standards and file formats, and fractals;
