But the collusion attack of several legal users is a potential threat. For the weakness of supporting fewer users in the original anti-collusion spread spectrum orthogonal digital fingerprinting scheme, a scalable spread spectrum orthogonal digital fingerprinting scheme is proposed. It is proved that this scheme increases the number of users the system supports and maintains the original scheme’s better performance against collusion from theoretical analysis and experiments.
