Abstract: Encryption can provide multimedia data with the desired security during transmission. However, once a piece of multimedia content is decrypted, the dishonest customer can redistribute it arbitrarily. Digital fingerprinting is an emerging technology for copyright protection of multimedia data, where unique identification information called fingerprint is embedded into each distributed copy. Once an unauthorised content copy is found somewhere, the embedded fingerprint can uniquely identify the source of the leakage. There are three main problems with digital fingerprinting systems, which are collusion attack, the distribution of the marked copies and the fairness of both the merchant and the customer. In this paper, we summarise the current state-of-the-art of the solutions to the main problems of digital fingerprinting.

Keywords: digital fingerprinting; digital copyright protection; secure multimedia distribution; collusion resistance; information hiding; encryption; embedded fingerprints; collusion attacks; fairness; data security.
