In this paper we present, by solving a variant of the guessing secrets problem defined by Chung, Graham and Leighton [3], a sequential traitor tracing scheme equipped with an efficient identification algorithm. Sequential traitor tracing schemes are used to detect piracy in multimedia content broadcast systems, where the traitors illegally rebroadcast the content they receive to unauthorized users.
