Data Privacy and Security: Encryption and Information Hiding
- Book Review, by David Salomon

Book Description
Computers are indispensable in today's world, and many professionals and researchers spend substantial amounts of time using them. New cryptographic methods scramble data, making it unreadable and thereby providing privacy. Another means to protecting privacy and securing data entails hiding it, an approach called steganography. "Data Privacy" focuses on keeping data private and covers classical cryptography, modern cryptography, and steganography in one volume. Each of these topics is presented and explained by describing various methods, techniques, and algorithms. Moreover, there are numerous helpful examples to solidify the reader's understanding and expertise with these methodologies. Topics and features: *incorporates both data encryption and data hiding in a single volume *supplies many exercises and solutions to support learning the material *presents information in an accessible way *concentrates on specific methodologies that readers can choose from and pursue An essential resource and monograph for all security researchers who want to understand and effectively use 'both' information hiding techniques and encryption to protect digital data.

Book Info

Data Privacy and Security: Encryption and Information Hiding

FROM OUR EDITORS

The Barnes & Noble Review
Securing your data is absolutely essential for doing business in the network-intensive environment you find yourself in today. If you are going to store your data, you must protect it from any sort of theft or abuse; and this is the book to show you how. There are time-tested, tried-and-true methods, as well as new methods, available to keep your data private -- and they are all thoroughly addressed in this excellent volume.

For example, the introduction tells the story of the Zimmermann telegram to illustrate the effect secret codes and code breaking can have on important historical events. Chapter 1 discusses monoalphabetic substitution ciphers, where each symbol is replaced by another symbol and the replacement (substitution) rule does not vary. Next, Chapter 2 is devoted to transposition ciphers. Polyalphabetic substitution ciphers are the topic of Chapter 3. A polyalphabetic substitution cipher can be made absolutely secure through the use of a one-time pad based on random numbers, so Chapter 4 is a survey of random numbers, methods for generating both true and pseudo-random numbers, and statistical tests for randomness. Chapter 5 is devoted to mechanical (or electromechanical) rotor encryption machines, specifically to the most famous of them, the German Enigma. Next, Chapters 6, 7, and 8 discuss modern cryptography. So, does the future belong to quantum cryptography? This question is the topic of Chapter 9, where the principles of this esoteric field are explained. Finally, steganography, the topic of Chapters 10 through 12, represents a different approach to privacy.

So, whether you are already responsible for data security and need to keep current with new methods and approaches, or whether you are moving into this arena and want to jump-start your own skill level, this outstanding book is the place to turn. Why? Because cryptography is very important and popular today -- it scrambles your data, making it unreadable and thereby providing privacy for the future! John Vacca
