New Traceability Codes Against a Generalized Collusion Attack for Digital Fingerprinting
In this paper, we discuss collusion-secure traceability codes for digital fingerprinting which is a technique for copyright protection of digital contents. We first state a generalization of conventional collusion attacks where illicit users of a digital content collude to create an illegal digital content. Then we propose a collusion-secure traceability code which can detect at least one colluder against it. We show the rate and properties of the proposed traceability code.
