Abstract: The traitor tracing scheme is a very useful tool for preventing piracy in the context of digital content broadcast. A traitor tracing procedure allows the data-suppliers to reveal the identities of the subscribers that were implicated in the construction of a pirate-device that illegally receives the digital content. In this paper, a traitor tracing scheme based on RS is proposed, which allows efficient deterministic traitor tracing that recovers all traitors.
