Ebook: Information hiding in speech signals for secure communication

While traditional digital encryption methods are useful, there are many other options for hiding your information. This book provides a number of methods to hide secret speech information using a variety of digital speech coding standards. It 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. --
