Digital fingerprinting achieves piracy tracing through embedding a unique serial number called fingerprint into each distributed digital copy secretly. Once an unauthorized content copy is discovered somewhere, the embedded fingerprint can uniquely identify the source of the pirated copy. How to defense collusive attack is one of the key problems when designing multimedia digital fingerprinting systems. Each colluder takes the equal risk in average collusion attack, which is fair to all colluders. Therefore, the average collusion attack is the most widely used attack model. In this paper, a digital fingerprinting scheme is proposed for protecting multimedia data, where the upper triangular matrix is used to construct the customer' fingerprints to resist the average collusion attack. The proposed fingerprinting scheme can accommodate a lot of customers, as the upper triangular matrix can be generated easily. Experiments show that the proposed scheme has good anti-collusion performance to the average attack.
