Short collusion-secure fingerprints based on dualbinary Hamming codes
J. Domingo-Ferrer, Jordi Herrera‐Joancomartí · Electronics Letters · 2000
Electronic copyright protection is increasingly dependent on fingerprinting and watermarking techniques. The properties of dual binary Hamming codes are exploited to obtain a fingerprinting scheme secure against collusion of two buyers. The advantage over previous proposals is that collusion security is obtained using well-known and shorter length error correcting codes.
