A Robust Anti-collusion Coding in Digital Fingerprinting System
Jie Yang, Xiaoxia Xu · 2006
A novel robust anti-collusion encoding scheme which combines the balanced incomplete design (BIBD) code with the turbo code in digital fingerprinting system is proposed. The fingerprints are coded by turbo code before embedding and then added to the wavelet domain which is suitable for the human vision. The experimental results indicate that the proposed algorithm can successfully resist not only the collusion attacks by colluders, but also the attacks such as noise when the digital products are transmitted in the channel. Meanwhile it enhances the overall resistance of the system
