In recent years, advances in digital technologies have created significant changes in the way we reproduce, distribute and market intellectual property (IP). Digital media can now be exploited by the IP owners to develop new and innovative business models for their products and services. The lowered cost of reproduction, storage and distribution, however, also invites much motivation for large-scale commercial infringement. In a world where piracy is a growing potential threat, the rights of the IP owners can be protected using three complementary weapons: Technology, legislation, and business models. Because of the diversity of IP (ranging from ebooks to songs and movies), no single solution is applicable to the protection of multimedia products in distribution networks.
IP is created as a result of intellectual activities in the industrial, scientific, literary and artistic fields. It is divided into two general categories: (1) Industrial property - includes inventions (patents), trademarks, industrial designs, and geographic indications of source, and (2) Copyright - includes literary and artistic works such as novels, poems and plays, films, musical works, artistic works such as drawings, paintings, photographs and sculptures, and architectural designs.
A digital home network is a cluster of digital audio/visual (A/V) devices including set-top boxes, TVs, VCRs, DVD players, and general-purpose computing devices such as personal computers. Copyrighted digital multimedia content may be delivered to the consumers from a number of sources including the Internet, and satellite, terrestrial or cable television systems. It may also be made available as prepackaged media (e.g., a digital tape or a digital video disc) at retail stores. Before releasing their content for distribution, the content owners may require protection by specifying certain access conditions and digital rights. Although legal institutions exist for protecting intellectual property, complimentary technical measures are needed to sustain financial returns and to ensure incentives for new creations. Recently, two fundamental groups of technologies, encryption and watermarking, have been identified for protecting copyrighted multimedia content in digital distribution networks. Encryption-based technologies transform content into unintelligible form. This transformation, being reversible in nature, allows perfect recovery of content before consumption. Technologies based on watermarking embed data directly into content, resulting in imperceptible degradation in visual quality.
End-to-end security is the most critical requirement for the creation of new digital markets where copyrighted content is a key product. Three major industries have a vital interest in this problem: The motion picture industry, the consumer electronics (CE) industry, and the information technology (IT) industry. This tutorial is an overview of the work done for protecting the content owners' investment in intellectual property. After an introduction to copyright and copyright industries, we examine how the technological, legal, and business solutions help maintain the incentive to supply the lifeblood of the markets.

Ahmet M. Eskicioglu received the B.S. degree from the Middle East Technical University (METU), Ankara, Turkey, and the M.S. and Ph.D. degrees from the University of Manchester Institute of Science and Technology (UMIST), England. He was with the Computer Engineering Department, METU from 1983 to 1992, the Department of Computer Sciences, University of North Texas from 1992 to 1995, and Thomson Multimedia Corporate Research, Indianapolis from 1996 to 2001.
Dr. Eskicioglu is with the Department of Computer and Information Science, Brooklyn College of the City University of New York. He has actively participated in the development of several national and international standards for copy protection and conditional access in the US and Europe. These include the Content Scramble System (CSS) for DVD players, the Advanced Television Systems Committee (ATSC) conditional access system architecture, the Electronics Industries Alliance (EIA) National Renewable Security Standard (NRSS), and the European Union's Digital Video Broadcasting (DVB) Content Protection and Copy Management (CPCM) System. While in the industry, he was the chair of Consumer Electronics Association (CEA) Working Group on Copy Protection, a member of the Copy Protection Technical Working Group (CPTWG), Advanced Television Systems Committee (ATSC) T3/S8 Conditional Access Ad Hoc Working Group, EIA and National Cable Television Association (NCTA) Joint Engineering Committee National Renewable Security Standard (NRSS) Subcommittee, and Society of Cable Telecommunications Engineers (SCTE) Digital Video Subcommittee.
Dr. Eskicioglu is on the program committee of several conferences on networks and security, and has been a reviewer for numerous conferences and journals including EURASIP Journal on Applied Signal Processing, The Computer Journal, ACM Multimedia Systems Journal, IEEE Transactions on Image Processing, IEEE Transactions on Multimedia, IEEE Transactions on Signal Processing, IS&T/SPIE's Security, Steganography, and Watermarking of Multimedia Contents VI Conference, Santa Clara, CA, January 18-22, 2004, and 11th Annual ACM International Conference on Multimedia (MM2003), Berkeley, CA, November 2-8, 2003. He holds several patents on copy protection, conditional access, and digital interface protection. Recently, he co-authored two book chapters entitled "Protection of Multimedia Content in Distribution Networks" and "Fundamentals of Multimedia Encryption Techniques" to appear in Multimedia Security Handbook by CRC Press in 2004.
Dr. Eskicioglu's teaching and research interests include data security, conditional access, digital rights management, copy protection, digital watermarking, and multimedia applications. He has been a National Science Foundation panelist, and a guest lecturer at the City University of New York, Polytechnic University, Fordham University, Drexel University, Purdue University, University of Manitoba, and Swiss Federal Institute of Technology.
