Embedded Multimedia Security Systems

Opening with a detailed review of existing techniques for selective encryption, this text then examines algorithms that combine both encryption and compression. The book also presents a selection of specific examples of the design and implementation of secure embedded multimedia systems. Features: reviews the historical developments and latest techniques in multimedia compression and encryption; discusses an approach to reduce the computational cost of multimedia encryption, while preserving the properties of compressed video; introduces a polymorphic wavelet architecture that can make dynamic resource allocation decisions according to the application requirements; proposes a light-weight multimedia encryption strategy based on a modified discrete wavelet transform; describes a reconfigurable hardware implementation of a chaotic filter bank scheme with enhanced security features; presents an encryption scheme for image and video data based on chaotic arithmetic coding.

Security is a major concern in an increasingly multimedia-defined universe where the Internet serves as an indispensable resource for information and entertainment. Digital Rights Management (DRM) is the technology by which network systems protect and provide access to critical and time-sensitive copyrighted material and/or personal information. This book equips savvy technology professionals and their aspiring collegiate protégés with the latest technologies, strategies and methodologies needed to successfully thwart off those who thrive on security holes and weaknesses. Filled with sample application scenarios and algorithms, this book provides an in-depth examination of present and future field technologies including encryption, authentication, copy control, tagging, tracing, conditional access and media identification. The authors present a diversified blend of theory and practice and focus on the constantly changing developments in multimedia applications thus providing an admirably comprehensive book. * Discusses state-of-the-art multimedia authentication and fingerprinting techniques * Presents several practical methodologies from industry, including broadcast encryption, digital media forensics and 3D mesh watermarking * Focuses on the need for security in multimedia applications found on computer networks, cell phones and emerging mobile computing devices

This book proposes new algorithms to ensure secured communications and prevent unauthorized data exchange in secured multimedia systems. Focusing on numerous applications’ algorithms and scenarios, it offers an in-depth analysis of data hiding technologies including watermarking, cryptography, encryption, copy control, and authentication. The authors present a framework for visual data hiding technologies that resolves emerging problems of modern multimedia applications in several contexts including the medical, healthcare, education, and wireless communication networking domains. Further, it introduces several intelligent security techniques with real-time implementation. As part of its comprehensive coverage, the book discusses contemporary multimedia authentication and fingerprinting techniques, while also proposing personal authentication/recognition systems based on hand images, surveillance system security using gait recognition, face recognition under restricted constraints such as dry/wet face conditions, and three-dimensional face identification using the approach developed here. This book equips perception technology professionals with the latest technologies, techniques, and strategies for multimedia security systems, offering a valuable resource for engineers and researchers working to develop security systems.

Technological advances have led to wide deployment and use of embedded systems in an increasing range of applications, from mobile phones to car, plane and spacecraft and from digital id’s to military systems in the field. Many of these applications place significant security requirements and have led to significant research activity in the area of security and embedded systems, due to the limited resources of conventional embedded systems. This emerging research area is of great importance to a large number of public and private organizations, due to their desire to deploy secure embedded systems in the field. This publication brings together one of the first international efforts to emphasize the importance of this emerging technical field and provides presentations of leading researchers in the field. Its objectives are to present the technologies and open problems of the emerging area of security and embedded systems, to present the latest research results in all aspects of security in embedded systems, and, finally, to provide a roadmap of the technology for the future. Considering the main directions of research in the field, three main areas are discussed: (i) foundations of security and embedded systems, (ii) secure embedded computing systems and (iii) telecommunications and network services.

Intellectual property owners who exploit new ways of reproducing, distributing, and marketing their creations digitally must also protect them from piracy. Multimedia Security Handbook addresses multiple issues related to the protection of digital media, including audio, image, and video content. This volume examines leading-edge multimedia securit

This book is a collection of outstanding content written by experts working in the field of multimedia security. It provides an insight about various techniques used in multimedia security and identifies its progress in both technological and algorithmic perspectives. In the contemporary world, digitization offers an effective mechanism to process, preserve and transfer all types of information. The incredible progresses in computing and communication technologies augmented by economic feasibility have revolutionized the world. The availability of efficient algorithms together with inexpensive digital recording and storage peripherals have created a multimedia era bringing conveniences to people in sharing the digital data that includes images, audio and video. The ever-increasing pace, at which the multimedia and communication technology is growing, has also made it possible to combine, replicate and distribute the content faster and easier, thereby empowering mankind by having a wealth of information at their disposal. However, security of multimedia is giving tough time to the research community around the globe, due to ever-increasing and efficient attacks carried out on multimedia data by intruders, eves-droppers and hackers. Further, duplication, unauthorized use and mal-distribution of digital content have become a serious challenge as it leads to copyright violation and is considered to be the principal reason that refrains the information providers in freely sharing their proprietary digital content. The book is useful for students, researchers and professionals to advance their study.

The great strides made over the past decade in the complexity and network functionality of embedded systems have significantly enhanced their attractiveness for use in critical applications such as medical devices and military communications. However, this expansion into critical areas has presented embedded engineers with a serious new problem: their designs are now being targeted by the same malicious attackers whose predations have plagued traditional systems for years. Rising concerns about data security in embedded devices are leading engineers to pay more attention to security assurance in their designs than ever before. This is particularly challenging due to embedded devices’ inherent resource constraints such as limited power and memory. Therefore, traditional security solutions must be customized to fit their profile, and entirely new security concepts must be explored. However, there are few resources available to help engineers understand how to implement security measures within the unique embedded context. This new book from embedded security expert Timothy Stapko is the first to provide engineers with a comprehensive guide to this pivotal topic. From a brief review of basic security concepts, through clear explanations of complex issues such as choosing the best cryptographic algorithms for embedded utilization, the reader is provided with all the information needed to successfully produce safe, secure embedded devices. The ONLY book dedicated to a comprehensive coverage of embedded security! Covers both hardware- and software-based embedded security solutions for preventing and dealing with attacks Application case studies support practical explanations of all key topics, including network protocols, wireless and cellular communications, languages (Java and C/++), compilers, web-based interfaces, cryptography, and an entire section on SSL
