This paper presents and discusses a web oriented, interactive anonymous buyer-seller watermarking protocol. In particular, the protocol enables buyers who are neither provided with digital certificates issued by trusted certification authorities (CAs) nor able to autonomously perform security actions to purchase digital contents distributed by web content providers (CPs) while keeping their identities unexposed during web transactions. The protocol also allows guilty buyers, i.e. who are responsible distributors of illegal replicas, to be unambiguously identified. Finally, the protocol has been designed so that CPs can exploit copyright protection services supplied by web service providers (SPs) in a security context. Thus, CPs can take advantage of complex protection services without having to implement them.
