ABSTRACT
As one of the main multimedia distribution channels, digital versatile disc (DVD) has been one of the main objectives attacked by pirates. Since DVD has the feature that once distributed, it is difficult to be controlled, finding the secure way to protect DVD contents is a challenging task. Until now, there have been some solutions, among which, content-scrambling system (CSS) and advanced access content system (AACS) are two important ones. Although AACS is much more powerful than CSS, such as adopting longer key, and using broadcasting encryption to block certain user, audiowatermark to resist recording, and video fingerprint to trace traitors, some recent attacks have broken it. In this chapter, after reviewing the existing techniques and protocols of DVDcontent distribution techniques includingCSS, AACS, and their following progresses,we emphasize on the usage of radio-frequency identification (RFID) for protecting DVD copyright and also indicate that introducing RFID for DVD content distribution will bring some other priorities. After that, we propose a method using RFID in key management for video decryption and fingerprint embedding. This chapter concludes by identifying some open research issues in secure DVD distribution based on RFID.
