New 2-secure Digital Fingerprinting Algorithm
Zhiguang Zhang · Journal of Chinese Computer Systems · 2009
Based on concatenated codes,a digital fingerprint coding and tracing algorithm is proposed. A new constructed code based on chaos is used as inner code,and IPP code is used as outer code. Both theoretical analysis and experimental results show that under the collusion size 2,by the fingerprinting algorithm,the owner can trace the traitors efficiently. Compared with Boneh-Shaw fingerprinting scheme,under the same collusion size and error probability,the algorithm shortens digital fingerprint length greatly.
