On Secure and Anonymous Buyer-Seller Watermarking Protocol
—Buyer-seller watermarking protocols incorporates digital watermarking with cryptography, in order to protect digital copyrights and privacy rights for the seller and the buyer before, during, and after purchase activities in e-commerce. In this paper, we analyze the security of some previously proposed schemes, and propose an secure and anonymous buyer-seller watermarking protocol. In contrast to early work, our improvement on the protocol’s security properties ensures that the design requirements are fulfilled. The proposed scheme is able to simultaneously resolve the piracy tracing problem, the customer’s rights problem, the unbinding problem, the anonymity problem, the conspiracy problem, and the dispute problem. In the proposed scheme, a buyer can purchase digital contents anonymously but his anonymity can be revoked as soon as he is adjudicated to be guilty by a legal institute, such as civil court.
