Asymptotic fingerprinting capacity in the Combined Digit Model

Dion Boesten and Boris Skoric

Abstract

We study the channel capacity of $q$-ary fingerprinting in the limit of large attacker coalitions. We extend known results by considering the Combined Digit Model, an attacker model that captures signal processing attacks such as averaging and noise addition. For $q=2$ we give results for various attack parameter settings. For $q\geq 3$ we present the relevant equations without providing a solution. We show how the channel capacity in the Restricted Digit Model is obtained as a limiting case of the Combined Digit Model.
