Digital watermarking is a potential solution to protecting intellectual property rights of digital products.An effective digital watermarking solution must be able to tackle the copyright protection,piracy trace,and other related problems.Several famous digital protocols are presented,and their deficiencies are pointed out.Based on the protocol proposed by LEI et al.,an effective buyer-seller watermarking protocol is proposed,which,with the idea of secret sharing and homomorphic public key cryptosystem,effectively solves the problem of customer's right-and-interest protection.The unbinding problem,the piracy tracing problem effectively.And with the introduction of trusted certification authority(CA),the conspiracy problem and the problem of buyer's participation in the dispute resolution could be solved effectively.
