Paper Abstract

This paper proposes a group-based fingerprinting scheme employing a joint coding and embedding strategy to trace multimedia distribution and proactively prevent the leak of multimedia information. Taking advantage of the prior knowledge on the collusion pattern, we construct compact fingerprints that consist of user sub-codeword and group sub-codeword and are embedded in host signal via spread spectrum technique. The detection is done in two levels, which identifies guilty groups through correlation and then narrows down to specific colluders through minimum distance decoding. Experimental results show that the proposed method provides higher collusion resistance than the existing non-grouped fingerprint codes.
