"On the Systematic Generation of Tardos\´s Fingerprinting Codes"

Digital fingerprinting is an emerging technology that offers proactive post-delivery protection of multimedia. It is used to trace back illegal users, where unique ID known as digital fingerprints is embedded into content before distribution. Tardos proposed binary codes for fingerprinting with a code length of theoretically minimum order, and the related works mainly focused on the reduction of the code length were presented. In this paper, for the reduction of computational costs required for the detection, a two-level Tardos code structure is introduced on the number of operations for calculating correlation scores. Furthermore, using the central limit theorem for correlation scores, we present a proper threshold for detecting colluders. The performance evaluation and analysis show that our proposed scheme is efficient.
