Digital watermarking is one of the most popular technologies for protecting the ownerships of digital contents or products. By embedding digital watermarks into digital contents, the owners of the contents can convince the judge or the trusted third party of their ownership of the contents. However, some attacks, such as the binding attacks and the men-in-the-middle attacks, are threatening the security of the watermarking mechanisms. Moreover, that the privacy of content buyers is not fully protected or the dispute between the buyers and the sellers cannot be fairly resolved also reduce the quality of the services. Although several buyer-seller watermarking protocols have been introduced in the literature, none can cope with all of the above problems. In this thesis, we will propose a novel buyer-seller watermarking protocol that can resolve the dispute between the buyers and the sellers fairly. Furthermore, not only is the proposed protocol immune to all of the known attacks, but it is truly buyer anonymous as well.
