Combinatorial Properties of Multimedia IPP Codes of Length 2
Jing Jiang, Chengyao Zhao, Minquan Cheng, Hongyan Dong · 2019
The concept of a code with the identifiable parent property for multimedia fingerprinting (MIPPC) were introduced to construct fingerprints resistant to the averaging collusion attack on multimedia contents. In this paper, we investigate the combinatorial properties of MIPPCs of length 2, and establish an equivalence between such a code and a bipartite graph. Consequently, several infinite families of MIPPCs of length 2 are obtained, one of which is asymptotically optimal.
