In recent years, the tremendous advancement of digital technology has increased the ease with which digital multimedia files are stored, transmitted, and reproduced. Because traditional copyright methods are unsuitable for establishing ownership, digital watermarking is considered one of the best solutions to prevent illegal and malicious copying and distribution of digital media. Advanced Techniques in Multimedia Watermarking: Image, Video and Audio Applications introduces readers to state-of-the-art research in multimedia watermarking. Covering new advancements in digital image watermarking and techniques for implementation and optimization across different media, this book is a valuable companion for professionals and researchers working in areas such as document watermarking, multimedia fingerprinting, information hiding, secured e-commerce, copyright protection, and hardware implementation of real-time multimedia watermarking.

Information Hiding: Steganography and Watermarking - Attacks and Countermeasures deals with information hiding. With the proliferation of multimedia on the Internet, information hiding addresses two areas of concern: privacy of information from surveillance (steganography) and protection of intellectual property (digital watermarking). Steganography (literally, covered writing) explores methods to hide the existence of hidden messages. These methods include invisible ink, microdot, digital signature, covert channel, and spread spectrum communication. Digital watermarks represent a commercial application of steganography. Watermarks can be used to track the copyright and ownership of electronic media. In this volume, the authors focus on techniques for hiding information in digital media. They analyze the hiding techniques to uncover their limitations. These limitations are employed to devise attacks against hidden information. The goal of these attacks is to expose the existence of a secret message or render a digital watermark unusable. In assessing these attacks, countermeasures are developed to assist in protecting digital watermarking systems. Understanding the limitations of the current methods will lead us to build more robust methods that can survive various manipulation and attacks. The more information that is placed in the public's reach on the Internet, the more owners of such information need to protect themselves from theft and false representation. Systems to analyze techniques for uncovering hidden information and recover seemingly destroyed information will be useful to law enforcement authorities in computer forensics and digital traffic analysis. Information Hiding: Steganography and Watermarking - Attacks and Countermeasures presents the authors' research contributions in three fundamental areas with respect to image-based steganography and watermarking: analysis of data hiding techniques, attacks against hidden information, and countermeasures to attacks against digital watermarks. Information Hiding: Steganography and Watermarking &endash; Attacks and Countermeasures is suitable for a secondary text in a graduate level course, and as a reference for researchers and practitioners in industry.

Now that information has become the lifeblood of your organization, you must be especially vigilant about assuring it. The hacker, spy, or cyber-thief of today can breach any barrier if it remains unchanged long enough or has even the tiniest leak. In Information Assurance Architecture, Keith D. Willett draws on his over 25 years of technical, security, and business experience to provide a framework for organizations to align information assurance with the enterprise and their overall mission. The Tools to Protect Your Secrets from Exposure This work provides the security industry with the know-how to create a formal information assurance architecture that complements an enterprise architecture, systems engineering, and the enterprise life cycle management (ELCM). Information Assurance Architecture consists of a framework, a process, and many supporting tools, templates and methodologies. The framework provides a reference model for the consideration of security in many contexts and from various perspectives; the process provides direction on how to apply that framework. Mr. Willett teaches readers how to identify and use the right tools for the right job. Furthermore, he demonstrates a disciplined approach in thinking about, planning, implementing and managing security, emphasizing that solid solutions can be made impenetrable when they are seamlessly integrated with the whole of an enterprise. Understand the Enterprise Context This book covers many information assurance subjects, including disaster recovery and firewalls. The objective is to present security services and security mechanisms in the context of information assurance architecture, and in an enterprise context of managing business risk. Anyone who utilizes the concepts taught in these pages will find them to be a valuable weapon in the arsenal of information protection.

Today the vast majority of the world's information resides in, is derived from, and is exchanged among multiple automated systems. Critical decisions are made, and critical action is taken based on information from these systems. Therefore, the information must be accurate, correct, and timely, and be manipulated, stored, retrieved, and exchanged safely, reliably, and securely. In a time when information is considered the latest commodity, information security should be top priority. A Practical Guide to Security Engineering and Information Assurance gives you an engineering approach to information security and information assurance (IA). The book examines the impact of accidental and malicious intentional action and inaction on information security and IA. Innovative long-term vendor, technology, and application-independent strategies show you how to protect your critical systems and data from accidental and intentional action and inaction that could lead to system failure or compromise. The author presents step-by-step, in-depth processes for defining information security and assurance goals, performing vulnerability and threat analysis, implementing and verifying the effectiveness of threat control measures, and conducting accident and incident investigations. She explores real-world strategies applicable to all systems, from small systems supporting a home-based business to those of a multinational corporation, government agency, or critical infrastructure system. The information revolution has brought its share of risks. Exploring the synergy between security, safety, and reliability engineering, A Practical Guide to Security Engineering and Information Assurance consolidates and organizes current thinking about information security/IA techniques, approaches, and best practices. As this book will show you, there is considerably more to information security/IA than firewalls, encryption, and virus protection.

The Most Progressive and Complete Guide to DDO-Based Ciphers Developers have long recognized that ciphers based on Permutation Networks (PNs) and Controlled Substitution-Permutation Networks (CSPNs) allow for the implementation of a variety of Data Driven Operations (DDOs). These DDOs can provide fast encryption without incurring excessive hardware costs in modern telecommunication networks. However, until now, with a few exceptions, most DDO-based ciphers have been poorly represented in available literature and have continued to remain known to only a small number of encryption experts. In Data-Driven Block Ciphers for Fast Telecommunication Systems, Nikolai Moldovyan and Alexander Moldovyan, major innovators and holders of several dozen international patents in encryption technology, provide the background and detail the applications needed to investigate new properties of PNs especially relevant to the improvement of modern wireless systems.Furthermore, they propose a universal architecture involving controlled bit permutation instruction that will permit the performance of both data-driven permutations and an arbitrary prescribed fixed permutation in a single cycle. Immediately improved efficiency for current and future fast telecommunication systems and mobile networksBecause of its simplicity and efficient use of current hardware, the embedding of this architecture is a highly attractive option for CPU manufacturers.By detailing all the relevant information into a single volume for the first time, the authors of this book make that option more feasible than ever before.

The modern dependence upon information technology and the corresponding information security regulations and requirements force companies to evaluate the security of their core business processes, mission critical data, and supporting IT environment. Combine this with a slowdown in IT spending resulting in justifications of every purchase, and security professionals are forced to scramble to find comprehensive and effective ways to assess their environment in order to discover and prioritize vulnerabilities, and to develop cost-effective solutions that show benefit to the business. A Practical Guide to Security Assessments is a process-focused approach that presents a structured methodology for conducting assessments. The key element of the methodology is an understanding of business goals and processes, and how security measures are aligned with business risks. The guide also emphasizes that resulting security recommendations should be cost-effective and commensurate with the security risk. The methodology described serves as a foundation for building and maintaining an information security program. In addition to the methodology, the book includes an Appendix that contains questionnaires that can be modified and used to conduct security assessments. This guide is for security professionals who can immediately apply the methodology on the job, and also benefits management who can use the methodology to better understand information security and identify areas for improvement.

An organization's employees are often more intimate with its computer system than anyone else. Many also have access to sensitive information regarding the company and its customers.
