Paper Abstract

This paper presents a traitor tracing method dedicated to video content distribution. It is based on a two-level approach with probabilistic traitor tracing codes. Codes are concatenated and decoded successively, the first one is used to decrease the decoding complexity and the second to accuse users. We use the well-known Tardos fingerprinting code for the accusation process and a Boneh-Shaw code with replication scheme to reduce the search space of users. This method ensures a decrease of the computational time compared to classical Tardos codes decoding. We present a method to select suspect groups of users and compare it to a more complex two-level Tardos code which follows the same construction.
