Book Description
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, the core concepts of secure speech communication, the ABS-based information hiding algorithm, and much more. This book shows how to implement a secure speech communication system, including applications to various network security states. Readers will find information hiding algorithms and techniques (embedding and extracting) that are capable of withstanding the advanced forms of attack. The book presents concepts and applications for all of the most widely used speech coding standards, including G.711, G.721, G.728, G.729 and GSM, along with corresponding hiding and extraction algorithms. Readers will also learn how to use a speech covert communication system over an IP network as well as a speech secure communication system applied in PSTN. Presents information hiding theory and the mathematical model used for information hiding in speech. Provides a number of methods to hide secret speech information using the most common digital speech coding standards. A combination of practice and theory enables programmers and system designers not only to implement tried and true encryption procedures, but also to consider probable future developments in their designs.

Book Description
The Pulitzer Prize–winning investigation into surveillance abuses and the Edward Snowden case that brought them to light. The NSA's extensive surveillance program has led Americans to question threats to their privacy. As reported by the Washington Post, in their Pulitzer Prize-winning coverage of whistleblower Edward Snowden's NSA leaks, NSA Secrets delves into the shadowy world of information gathering, exposing how data about you is being collected every day. From his earliest encrypted exchanges with reporters, Edward Snowden knew he was a man in danger. Sitting on a mountain of incriminating evidence about the NSA surveillance programs, Snowden was prepared to risk his freedom, and his very life, to let the world know about the perceived overreach of the NSA and the massive collection of personal information that was carried out in the name of national security by the U.S. government. The Washington Post’s complete coverage of the NSA spying scandal, which it helped break, is now collected in one place to give as comprehensive a view of the story as is known. From the first contact with Snowden to the latest revelations in worldwide cellphone tracking, the award-winning reporters at the Post have vigorously reported on the scope of the NSA’s surveillance. Snowden called the internet “a TV that watches you,” and accused the government of “abusing [it] in secret to extend their powers beyond what is necessary and appropriate.” Here, the secrets of those who tried in vain to remain in the shadows are revealed.
