Abstract

Several new video and image watermarking proposals are based on Informed Coding and Informed Embedding. However, these systems can be not easily used in fingerprinting schemes because they do not satisfy the marking assumption defined in [1]. In this paper we discuss some guidelines to adapt a watermarking system based on informed coding and informed embedding to a generic fingerprinting code, while keeping up with the marking assumption, that is to say, when as a result of one collusion attack of two users, that have different marks that represent the value 0 in the nth position, we have a pirate mark wich represents the 0 value in this same nth position. This can be achieved modifying the work of Miller, Doër and Cox in [2].
