Information Hiding in Speech Signals for Secure Communication


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.




Multimedia Modeling


Book Description

Since the beginning of human history we have had a communication network that is identical with the physical distribution network. In the late 19th century we established the energy network to distribute electric and thermal energy, launching the modern society. The analog communication network became popular in the middle of the 20th century. And now, at the end of the 20th century, we have global digital information networks.Along with the advancement of the communication network, the progress of the information processing technology can be classified into three historical phases. The first phase technology is physical information processing, treating physical data from the real world. This technology is often called ?signal processing? and is based on the physical law of nature. The second phase is free from the physical constraints. It is logical information processing, dealing with knowledge and rules. The most important aspect of this phase is consistency. ?Provable? is employed to confirm the reality of the system.Based on the advanced computer and network technology, we are entering the third phase of information processing, which is ?Kansei? information processing. (?Kansei? is a Japanese word expressing some subjective ability referred to as ?sensibility?, ?intuition?, ?affection? or ?emotion?). Emotional resonance or consent is important in the pursuit of reality in this phase.Multimedia modeling to harmonize different media and systems is one of the key technologies in the third phase of information processing. It will provide a next generation framework to construct a human-centered information environment that is more comfortable and more productive.This volume is devoted to a discussion on effective modeling of multimedia information and systems for a wide range of applications. It contains 30 technical articles, all of which were selected, after vigorous peer reviews, for presentation at the International Conference on Multimedia Modeling held in Nagano, Japan, on 13-15 November 2000.

Multimedia Storage and Retrieval


Book Description

The success of multimedia information systems to adequately meet the needs of accessing and presenting audio/video information from a large multimedia server depends heavily on the proper use of storage and retrieval algorithms suitable for this task. Multimedia Storage and Retrieval describes various algorithms from simple to sophisticated: from single user to multiple users, from constant-bit-rate to variable-bit-rate streams, and from single disk to multiple disks. This book emphasizes storage and retrieval of video data using magnetic disk systems and its elementary, mathematical approach concentrates on the fundamental algorithms. Provides those new to the subject with the basic principles of the design and analysis of video-on-demand systems and guides the reader towards a thorough understanding of the field. Comprehensively covers disk scheduling algorithms, including round robin, double and triple buffering, grouped sweeping, and dual sweep. Extensively treats storage strategies, including contiguous and segmented storage, track pairing, striping, and random redundant storage. Concludes with further optimizations in the area of video transmission, covering bit-rate smoothing and near video-on-demand strategies. Senior undergraduate and graduate students on computer science and electrical engineering courses will all find this book appealing. Researchers and those in industry will also find it an invaluable reference.




Protocols for Multimedia Systems


Book Description

This conference in Enschede, The Netherlands, is the sixth in a series of international conferences and workshops under the title Protocols for Multimedia Systems, abbreviated as PROMS. The first PROMS workshop took place in June 1994 in Berlin, Germany, followed by workshops in Salzburg, Austria (October 1995) and Madrid, Spain (October 1996). In 1997, PROMS formed a temporary alliance with Multimedia Networking, a conference previously held in Aizu, Japan, in 1995. This led to the international conference on Protocols for Multimedia Systems – Multimedia Networking, PROMS MmNet, that took place in Santiago, Chile (November 1997). Since then PROMS has been announced as an international conference, although informal contacts and interactive sessions – as in a workshop – were retained as a desirable feature of PROMS. After a gap of three years, PROMS was organized in Cracow, Poland (October 2000), for the fifth time. We consider it a challenge to make this sixth edition of PROMS as successful as the previous events. The goal of the PROMS series of conferences and workshops is to contribute to scientific, strategic, and practical cooperation between research institutes and industrial companies in the area of multimedia protocols. This is also the goal of PROMS 2001. The basic theme of this conference continues to be multimedia protocols, both at the network and application level, although the increasing interest in wireless, mobility, and quality of service as interrelated topics with relevance to multimedia are reflected in the current program.

Information Hiding


Book Description

Although the animal may be, as Nietzsche argued, ahistorical, living completely in the present, it nonetheless plays a crucial role in human history. The fascination with animals that leads not only to a desire to observe and even live alongside them, but to capture or kill them, is found in all civilizations. The essays collected in Beastly Natures show how animals have been brought into human culture, literally helping to build our societies (as domesticated animals have done) or contributing, often in problematic ways, to our concept of the wild. The book begins with a group of essays that approach the historical relevance of human-animal relations seen from the perspectives of various disciplines and suggest ways in which animals might be brought into formal studies of history. Differences in species and location can greatly affect the shape of human-animal interaction, and so the essays that follow address a wide spectrum of topics, including the demanding fate of the working horse, the complex image of the American alligator (at turns a dangerous predator and a tourist attraction), the zoo gardens of Victorian England, the iconography of the rhinoceros and the preference it reveals in society for myth over science, relations between humans and wolves in Europe, and what we can learn from society’s enthusiasm for "political" animals, such as the pets of the American presidents and the Soviet Union’s "space dogs." Taken together, these essays suggest new ways of looking not only at animals but at human history. Contributors Mark V.
