Ethical dilemmas have risen in number and intensity with the increasing dependence of contemporary society on computers and computer networks. Despite the proliferation of expert remedies, viable solutions to computer security issues remain too elusive, and society continues to suffer at the hands of cyber criminals, vandals, and hackers. This thoroughly revised and expanded fourth edition of the successful Ethical and Social Issues in the Information Age provides an up-to-date examination of the ethical, social, and policy challenges stemming from the emergence of cyberspace, the convergence of telecommunication and computing technologies, and the miniaturization of computing, telecommunication, and information-enabling devices. This accessible textbook/reference broadly surveys thought-provoking questions about the impact of these new technologies, with particular emphasis on the rapid growth of a multitude of computer networks, including the Internet. It assumes only a very modest familiarity with basic computer literacy. Topics and features: • Describes how changes in information technology influence morality and the law • Establishes a philosophical framework and analytical tools for discussing moral theories and problems in ethical relativism (NEW) • Offers a pertinent discussion on privacy, surveillance, civil liberties, harassment, and discrimination • Supplies an overview of the history of computing science in hardware, software, and networking (NEW) • Examines how developments in information technology have changed the traditional issues of intellectual property rights • Surveys the evolution of computer crimes, their types, costs on society, and strategies of detection and prevention, as well as techniques in electronic crime investigation • Discusses the new frontiers of ethics: virtual reality, artificial intelligence, and the Internet • Reviews the new realities of computer networks, and their implications for global ethics, culture, and economics (NEW) • Introduces the fundamentals of network-security system design and operation, revealing vulnerable areas in computer network infrastructure • Explores biometric techniques to system access control • Incorporates recent requirements for computer curricula • Provides exercises, objectives, and issues for discussion with every chapter This comprehensive text/reference provides updated discussion of the ethical and social issues that continue to evolve as computing and information technologies proliferate. Students at all levels who need to learn about computer ethics, the legal aspects of computing, network security, computer crime investigation, and biometrics will find this well-documented work an invaluable resource. The book is also highly useful for practitioners needing such insights for their work.

Locally decodable codes (LDCs) are codes that simultaneously provide efficient random access retrieval and high noise resilience by allowing reliable reconstruction of an arbitrary bit of a message by looking at only a small number of randomly chosen codeword bits. Local decodability comes with a certain loss in terms of efficiency – specifically, locally decodable codes require longer codeword lengths than their classical counterparts. Private information retrieval (PIR) schemes are cryptographic protocols designed to safeguard the privacy of database users. They allow clients to retrieve records from public databases while completely hiding the identity of the retrieved records from database owners. In this book the author provides a fresh algebraic look at the theory of locally decodable codes and private information retrieval schemes, obtaining new families of each which have much better parameters than those of previously known constructions, and he also proves limitations of two server PIRs in a restricted setting that covers all currently known schemes. The author's related thesis won the ACM Dissertation Award in 2007, and this book includes some expanded sections and proofs, and notes on recent developments.

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 exercises Clearly 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.
