Abstract :
Digital watermarking techniques have been used for preventing an illegal copying and re-distributing of contents. A collusion attack is a strong attack against digital watermarking schemes. To prevent such attacks, a collusion secure fingerprint code can be used. Collusion secure fingerprint code have been studied widely and many codes have been proposed. However, a code length of them are too long to embed it into a content using digital watermarking.
