Abstract(in English) | Digital ?ngerprinting codes are embedded in digital contents for protecting copyrights of the digital contents against malicious users who generate a pirated copy. Usually, digital ?ngerprinting codes should be designed so that a part (or all) of the malicious users can be speci?ed with high probability. In this paper, we consider the situation where two malicious users choose two distinct attack models and use their mixture for generation of a pirated copy. We succeed in obtaining a lower bound of the joint capacity for this case by giving an identi?cation algorithm of the two malicious users based on a certain score function. Key words digital ?ngerprintingcodes, collusion attack, joint capacity. |
