Abstract :
We proposed an effective and efficiency anti-collusion fingerprint scheme based on inner code with orthogonal fingerprint in tandem and outer code with LDPC code that can not only have a good collusion-free performance in the fingerprint system but also have good error correct performance and can resist many other attacks unconsciously such as noise, which protected distributor´s copyright and data integrity.
