Abstract(in English) | In fingerprinting code against collusion attack, the optimal detector which detect colluders has been proposed. However, the detector needs two kinds of information about collusion strategy and the number of colluders. In our previous work, these parameters are estimated only from a pirated codeword in noiseless case. In this study, we extend the method in noise case to consider a practical situation. In case of AWGN, the ratio of between the symbol ``0'' and ``1'' can be modeled by a well-known Gaussian mixture model, and hence the ratio can be estimated by using a statistical algorithm. As a result of computational simulation, we also realize the estimator for parameters and the optimal detector in noise case. |
