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 proteges 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

Peer-to-Peer (P2P) networks enable users to directly share digital content (such as audio, video, and text files) as well as real-time data (such as telephony traffic) with other users without depending on a central server. Although originally popularized by unlicensed online music services such as Napster, P2P networking has recently emerged as a viable multimillion dollar business model for the distribution of academic and clinical information, telecommunications, and social networking. Written at an accessible level for any reader familiar with fundamental Internet protocols, Peer-to-Peer Networking and Applications explains the conceptual operations and architecture underlying basic P2P systems using well-known commercial systems as models. The book also delineates the latest research directions, thereby providing not only a sophisticated understanding of current systems, but also the means to improve upon these systems with innovations that will better performance, security, and flexibility. Peer-to-Peer Networking and Applications is thus both a valuable starting point and an important reference to those practioners employed by any of the 200 companies with approximately $400 million invested in this new and lucrative technology.
* Uses well-known commercial P2P systems as models, thus demonstrating real-world applicability.
* Discusses how current research trends in wireless networking, high-def content, DRM, etc. will intersect with P2P, allowing readers to account for future developments in their designs.
* Provides online access to the Overlay Weaver P2P emulator, an open source tool that supports a number of peer-to-peer applications with which readers can practice.
