Abstract :
It simply introduces a new digital fingerprint coding based on LDPC code in this paper. The new technology of coding combines the BIBD code and the LDPC code that have good performance in the fingerprint system. So the digital products with new coding can not only resist collusion attack by illegal users, but also resist the other attacks unconsciously such as noise, which protected their copyright and integrity.
