| Abstract(in English) | Illegal copies of digital contents are spreading due to the development of the Internet. Digital finger-printing codes provide a method in which we can identify malicious users who generate illegal copies under the collusion attack. In this paper we discuss performance of a probabilistic digital fingerprinting code in which codewords are generated according to a certain probability distribution. Although we often use such i.i.d. codewords in digital fingerprinting codes, there also exists a digital fingerprinting code such as the Tardos code where the codewords are generated according to a varying distribution. In this paper, we use a tracing algorithm based on the marking assumption and evaluate the probability of misidentification of a collusion of two malicious users. We show the existence of the situation where a digital fingerprinting code generated from a nonstationary distribution outperforms a digital fingerprinting code generated from a fixed stationary distribution. |
