Linear Combination Collusion Attack and its Application on an Anti-Collusion Fingerprinting
Yongdong Wu · 2006
This paper presents a linear combination collusion attack (LCCA) which is a generalization of the average attack model. LCCA generates a pirated image of good quality but prevents traitors from being identified. As an application example, LCCA is used to attack a fingerprinting scheme published in IEEE Transactions on Signal Processing. The theoretical analysis and experiment results demonstrate that the attack is practical and efficient.
