Attacks on Kuribayashi's Fingerprinting Scheme
Hans Georg Schaathun · IEEE Transactions on Information Forensics and Security · 2014
The main threat against fingerprinting systems is collusion attacks. The attack most commonly assumed in the literature is a combination of averaging the collusion fingerprints and additive noise. In this correspondence, we demonstrate that the recently proposed fingerprinting scheme of Kuribayashi's is very vulnerable to certain nonlinear collusion attacks.
