Digital Fingerprint Code and Anti-collusion Attack Scheme
Yang Shi-pingab · Communications technology · 2011
A new way is proposed to solve the anti-collusion code attack from legal digital fingerprint.The CDMA technology is employed to eliminate the interferences between multi-users access,and one of the interferences is that many legal users collude their digital fingerprint and generate another illegal digital fingerprint,and thus violate the copyright of the digital products.The elimination of interferences means the elimination of collusion attack.The framework of the anti-collusion digital fingerprint code and the specific implementation,including in-depth theoretical analysis,are given in this paper.
