Abstract :
A novel robust anti-collusion encoding scheme which combines the balanced incomplete block design (BIBD) code with turbo code in digital fingerprinting system is proposed. The fingerprints are coded by Turbo code before embedding and added to the wavelet domain which is suitable for the visual characteristics of human. The experimental results indicate that the proposed algorithm can successfully resist not only the collusion attacks by colluders, but also the other attacks such as noise when the digital products are transmitted in the channel. Meanwhile it can decrease the bit error rate (BER) of the fingerprints and enhance the overall resistance of the system
