| Abstract(in English) | Digital fingerprinting codes are embedded in licenced digital contents for preventing illegal distribution by malicious users. Digital fingerprinting codes are usually required to have the ability to specify a part (or all) of a collusion of malicious users that generates the pirated copy. In this paper we consider a information-theoretic model of the digital fingerprinting code and characterize the maximum rate of the users (the capacity of the digital fingerprinting code) such that all the malicious users in a collusion can be specified under a certain assumption. In our model, codewords of length n are independently generated subject to a certain probability distribution. In addition, a collusion of size at most u generates an illegal codeword subject to a conditional probability distribution independently. We show that the error probability P_n goes to zero as n→∞ if the rate is less than the capacity, and the rate is less than or equal to the capacity if P_n goes to zero as n→∞ under certain assumptions including the symmetry of the conditional probability distribution. |
