Short 3-Secure Fingerprinting Codes for Copyright Protection
A construction is presented to obtain 3-secure fingerprinting codes for copyright protection. Resistance against collusions of up to three buyers is achieved with a codeword length dramatically shorter than the one required by the general Boneh-Shaw construction. Thus the proposed fingerprints require much less embedding capacity. Due to their very clandestine nature, collusions tend to involve a small number of buyers, so that there is plenty of use for codes providing cost-effective protection against collusions of size up to 3.
